exploration and production

Using the latest technology, Chevron continues to make major discoveries in the United States while maintaining strong production in mature fields.

Chevron is one of the largest hydrocarbon producers in the United States. In 2015, we produced an average of 720,000 barrels of net oil-equivalent per day, or 27 percent of the corporation’s worldwide total.

Our company’s major operations in the United States are in California, the Gulf of Mexico, Colorado, Louisiana, New Mexico, Ohio, Oklahoma, Pennsylvania, Texas, West Virginia and Wyoming.

At the end of 2015, Chevron was the largest leaseholder in the Gulf of Mexico.

Gulf of mexico shelf
Chevron is the largest producer of crude oil and natural gas on the Gulf of Mexico shelf. Daily net production during 2015 averaged 45,000 barrels of crude oil, 218 million cubic feet of natural gas and 6,000 barrels of natural gas liquids (NGLs).

In 2015, we drilled 41 development and delineation wells.

Deepwater gulf of mexico
Chevron is one of the leading leaseholders in the deepwater Gulf of Mexico, with a long history of technical achievement and operational safety.

Average net daily production in 2015 was 119,000 barrels of crude oil, 97 million cubic feet of natural gas and 10,000 barrels of NGLs, primarily from the Blind Faith, Caesar/Tonga, Jack, St. Malo, Tahiti and Tubular Bells fields and the Perdido Regional Development.

Marine Well Containment Company LLC, a nonprofit company sponsored by Chevron and other major energy companies, commissioned its expanded containment system in the third quarter of 2015. The system provides increased capacity and compatibility with a wider range of well designs, flow rates and environmental conditions.

The Jack and St. Malo fields in the Walker Ridge area—in a water depth of 7,000 feet (2,134 m)—are being jointly developed with a host floating production unit centrally located between the two fields. Chevron has a 50 percent interest in the Jack Field and a 51 percent interest in the St. Malo Field and operates both. Production from the development is linked to the market by the Jack/St. Malo oil and gas export pipelines. Total daily production in 2015 averaged 61,000 barrels of liquids (31,000 net) and 10 million cubic feet of natural gas (5 million net). Production ramp-up and development drilling for the first development phase continued in 2015. The second phase of the development plan includes four more development wells. Drilling began in October 2015 and is expected to continue in 2016. First oil from Stage 2 is expected in 2017.

Production from the Jack/St. Malo development is expected to ramp up to a total daily production rate of 94,000 barrels of crude oil and 21 million cubic feet of natural gas. Total potentially recoverable oil-equivalent resources are estimated to exceed 500 million barrels. 

Also in Walker Ridge is the 60 percent-owned and operated Big Foot project. The facility is designed with a capacity of 75,000 barrels of crude oil and 25 million cubic feet of natural gas per day. Work to install the platform was suspended in the second quarter of 2015 when nine of 16 mooring tendons lost buoyancy. The remaining tendons were recovered, and the platform was moved to a safe harbor location. First oil is expected in the second half of 2018.

In 2015, net daily production at the 58 percent-owned and operated Tahiti Field averaged 31,000 barrels of crude oil, 12 million cubic feet of natural gas and 2,000 barrels of NGLs. The next development phase, the Tahiti Vertical Expansion Project, began front-end design and development work in 2015, and a final investment decision is expected in mid-2016.

Chevron also has a role in these deepwater developments:

  • Tubular Bells Field is in a water depth of 4,300 feet (1,311 m) in the Mississippi Canyon area. Chevron has a 42.9 percent nonoperated working interest in the development. In 2015, net daily production averaged 10,000 barrels of crude oil and 20 million cubic feet of natural gas. Development drilling continued in 2015.
  • Mad Dog Field averaged net daily production of 4,000 barrels of liquids and 1 million cubic feet of natural gas in 2015. Also in 2015, front-end engineering and design work continued on the Mad Dog 2 Project, which would develop the southern portion of the Mad Dog Field. 
  • Stampede is a joint development of the Knotty Head and Pony fields, in Green Canyon. Chevron holds a 25 percent nonoperated working interest. The fields are in a water depth of 3,500 feet (1,067 m), with a reservoir depth of 30,000 feet (9,144 m). The development is designed for a capacity of 80,000 barrels of crude oil and 40 million cubic feet of natural gas per day. Development drilling began in the fourth quarter of 2015, with first oil expected in 2018. 

During 2015 and early 2016, the company participated in nine deepwater wells—five appraisal and four exploration. We discovered crude oil at the 50 percent-owned and operated Sicily exploration in the second quarter of 2015. That was followed by the drilling of an appraisal well at Sicily in December. We successfully completed appraisal work at the 55 percent-owned and operated Anchor discovery in the fourth quarter of 2015. Drilling began on a new appraisal well at Anchor in the first quarter of 2016. In the last quarter of 2015, we began drilling an exploration well at the 36 percent-owned and operated Gibson exploration. That well is expected to be completed in the second quarter of 2016.

Chevron acquired 13 new deepwater leases in the Gulf of Mexico in 2015.

At 179,000 barrels per day in 2015, Chevron is California’s largest producer in net oil-equivalent. We have 16,000 wells in operation, primarily in the San Joaquin Valley. Net daily production in 2015 averaged 166,000 barrels of crude oil, 61 million cubic feet of natural gas and 3,000 barrels of NGLs.

The majority of the production is from Chevron-operated leases that are part of three major crude oil fields in the San Joaquin Valley—Kern River, Midway Sunset and Cymric. We also operate and hold interests in the San Ardo, Coalinga and Lost Hills fields. Our expertise in steamflood operations—which makes the oil flow more easily—has resulted in a crude oil recovery rate at the Kern River Field of more than 60 percent.

Chevron continues to leverage leading-edge heat management capabilities in the recovery of these hydrocarbons, with emphasis on improved energy efficiency through new technology and processes. An active development drilling program and increased steam injection have helped reverse the decline rate on company-operated properties from 7 percent in 2010 to a 2 percent increase in 2015.

Chevron also holds a nonoperated working interest of approximately 23 percent in four producing zones at the Elk Hills Field. 

Chevron operates crude oil and natural gas fields in the midcontinental United States—primarily in Colorado, New Mexico, Oklahoma, Texas and Wyoming. In 2015, the company’s net daily production in these areas averaged 116,000 barrels of crude oil, 600 million cubic feet of natural gas and 34,000 barrels of NGLs.

Chevron is the largest net acreage leaseholder and one of the largest producers in the Permian Basin of West Texas and southeastern New Mexico. Operations in the Permian date back to 1926, and total net production has surpassed 5 billion barrels of oil-equivalent. The Permian is composed of several basins, including the liquids-rich Midland and Delaware basins, and it offers opportunities for conventional resources as well as for shale and other tight resources. Substantial conventional hydrocarbons are recoverable through secondary and tertiary methods that increase ultimate recovery and offset field decline. Chevron’s capital spending on exploration and development of the approximately 1.5 million net acres (6,070 sq km) of shale and other tight resources in the Midland and Delaware basins is focused on horizontal wells with multistage fracture stimulation.

The company has approximately 500,000 net acres (2,023 sq km) in the Midland Basin. At the end of 2015, four company-operated rigs were active and 115 company-operated wells were drill during the year. The company also participated in 72 nonoperated wells during 2015, with three nonoperated rigs active at year-end. 

Chevron is the largest acreage holder in the Delaware Basin, with approximately 1 million net acres (4,047 sq km). A total of 32 company-operated wells were drilled in 2015, and two company-operated rigs were active at year-end. We also participated in 108 nonoperated wells in 2015, with 11 nonoperated rigs active at year-end. Five of the nonoperated active rigs were in the company’s two joint development agreement areas in the Delaware Basin that include access to related infrastructure. These operated and nonoperated development activities have defined multiple liquids-rich stacked plays. 

Appalachian basin
The company is a significant leaseholder in the Marcellus Shale and the Utica Shale, primarily located in southwestern Pennsylvania, eastern Ohio and the West Virginia panhandle. In 2015, the company’s net daily production in these areas averaged 334 million cubic feet of natural gas. 

Chevron has 600,000 net acres (2,425 sq km) in the Marcellus Shale. During 2015, 56 development wells were drilled. The company had two drilling rigs in operation at year-end. Development is proceeding at a measured pace, focused on improving execution capability, well performance and cost effectiveness.

In the Utica Shale, Chevron has approximately 320,000 net acres (1,295 sq km). Two exploratory wells were drilled in 2015 to acquire data necessary for potential future development.


Our subsidiary Chevron Pipe Line Company transports crude oil, refined petroleum products, liquefied petroleum gas, natural gas, natural gas liquids and chemicals within the United States. Chevron also operates pipelines for its 50 percent-owned CPChem affiliate.

In the U.S. Gulf of Mexico, Chevron completed and commissioned a 136-mile (219-km), 24-inch (61-cm) crude oil pipeline from the Jack/St. Malo deepwater production facility to a platform in Green Canyon Block 19 on the U.S. Gulf of Mexico shelf, where there is a connection to pipelines that deliver crude oil into Texas and Louisiana. 

Chevron Shipping Company LLC is based in San Ramon, California.

Our fleet uses a combination of single-voyage charters, short- and medium-term charters, and company-owned and bareboat-chartered vessels. Our fleet includes both U.S.- and foreign-flagged vessels. The U.S.-flagged vessels transport refined products, primarily in the coastal waters of the United States. The foreign-flagged vessels primarily transport crude, LNG, oil, and refined products and feedstocks to and from various locations worldwide. In 2015, the company took delivery of its third and fourth LNG carriers, expanding our fleet to support Chevron’s growing global LNG portfolio. Chevron also owns a one-sixth interest in each of seven LNG carriers that transport cargoes for the North West Shelf Venture in Australia. 

Power generation
Our subsidiary Chevron Power and Energy Management Company manages Chevron’s interest in our gas-fired and renewable power generation assets and provides comprehensive commercial, engineering and operational support services to improve the power reliability and energy efficiency of Chevron operations worldwide.

marketing and retail

Chevron manufactures and sells a range of high-quality refined products, including gasoline, diesel, marine and aviation fuels, premium base oil, finished lubricants, and fuel oil additives. We own five U.S. fuel refineries and have a network of Chevron® and Texaco® service stations.


Chevron has a crude refining capacity in the United States of more than 900,000 barrels per day. Refineries are in Richmond and El Segundo, California; Salt Lake City, Utah; and Pascagoula, Mississippi.

We continued to improve our refineries’ flexibility and their ability to process lower-cost crude oil. At the Richmond Refinery, the company is resuming preconstruction work on its modernization project, which will replace some of the refinery’s processing equipment with more modern technology that is designed to meet or exceed the nation’s toughest applicable environmental and safety standards.

Chevron became a leader in premium base oil production with the startup of the lubricant base-oil facility at the Pascagoula Refinery in 2014.

Americas products
Chevron’s fuel marketing efforts are managed by our Americas Products organization. Chevron has a network of nearly 8,000 Chevron® and Texaco® service stations in the United States.

The Chevron and Texaco brands, both of which contain our Techron® gasoline additive, are well known to consumers. Chevron’s award-winning ExtraMile® convenience stores operate at more than 700 company-owned and franchised sites in California, Oregon and Washington.

We are among the leading suppliers of jet and aviation fuels to commercial airlines, as well as a key supplier to the military. Chevron markets aviation fuel to commercial airlines at more than 40 airports in the United States and supplies many general aviation locations as well.


Chevron sells finished lubricants to commercial, industrial and retail customers nationwide. Our U.S. line of lubricant and coolant products includes our well-known Chevron Havoline® and Chevron Delo® motor oils.

The 25,000-barrel-per-day premium base oil facility at our Pascagoula Refinery began operations in July 2014. The $1.4 billion project made Chevron a leading producer of premium base oils.

Supply and trading
Chevron’s Supply and Trading organization provides a critical link between Chevron’s upstream and downstream operations. Headquartered in Houston, Texas, with additional trading hubs in London, Singapore and San Ramon, California, it provides commercial support for crude oil and natural gas production operations and our refining and marketing network. The organization manages daily commodity transactions averaging 5 million barrels of liquids and 5 billion cubic feet of gas.  

The Crude Supply and Trading group buys, sells and transports all major grades of crude oil and secures the best prices for selling Chevron’s upstream production and for purchasing crudes used by our refineries. 

The Product Supply and Trading group manages global supply, trading and logistics for feedstocks, fuels, and refined products like gasoline, naphtha, diesel, jet fuel, heavy fuels, biofuels, coke, sulfur, ammonia, asphalt, and other products for the manufacturing and marketing network. 

The Gas Supply and Trading (GSAT) group markets natural gas to wholesale and large end-use consumers, such as utility and industrial customers and pipeline operators. The GSAT also negotiates supply commitments of natural gas through short-term and long-term LNG marketing opportunities in North America, Europe and the Asia-Pacific region.


Chevron is one of the world’s top producers of commodity petrochemicals, through the 50 percent-owned joint venture CPChem. Based in The Woodlands, Texas,CPChem manufactures building-block chemicals—olefins, polyolefins, aromatics, styrenics and specialty products—used to make consumer and industrial products.

CPChem continues construction of its U.S. Gulf Coast Petrochemicals Project in Texas. The $6 billion project includes an ethane cracker with an annual design capacity of 1.5 million metric tons of ethylene at the Cedar Bayou plant and two polyethylene units in Old Ocean, each with an annual design capacity of 500,000 metric tons. Startup is expected in mid-2017.

Construction to expand the Cedar Bayou facility’s normal alpha olefin capacity was completed in 2015. Normal alpha olefins and their derivatives are used extensively as plasticizers, synthetic motor oils, lubricants and automotive additives and as building blocks in the development of new chemical products. 

In 2016, CPChem started construction of a state-of-the-art polyethylene pilot plant at its research and technology facility in Bartlesville, Oklahoma. The testing site will provide leading-edge polyethylene research, including new catalyst and polymer development as well as polymer performance enhancements. Completion of the new pilot plant is expected in 2017.

  • A technology center, in Richmond, California
  • A manufacturing plant, in Belle Chasse, Louisiana
  • The sales headquarters for the Americas region in Houston, Texas


Chevron has three technology companies that support the company’s businesses. The work that these companies do is integrated across Chevron—the groundbreaking technologies we are developing are deployed throughout the company.

Chevron continues advancing capabilities in subsurface imaging and modeling to support exploration, field development and reservoir management. The company integrates rapid advances in commercial seismic data acquisition techniques with proprietary imaging capability, well information, reservoir models and regional knowledge to provide a competitive advantage in geologically complex basins worldwide.

Chevron’s Gulf of Mexico business unit successfully developed and executed a rigless hydraulic intervention approach that reduces costs and production shut-in time relative to the historical rig-based process. The first application of this was on five wells in the Tahiti Field where we saw a 52 percent increase in production and an 85 percent decrease in cost. Where applicable, this technology will be used across Gulf of Mexico deepwater assets.

The company continues to develop technology innovations in heavy oil recovery that reduce costs, reduce environmental impact and help capture previously undevelopable reserves. In 2015, Chevron surpassed 24 months of operations at the company’s first horizontal steam injection well pilot in the San Joaquin Valley, California. The pilot included the successful trial of industry-advancing capability in downhole fiber optic–based steam injection flow profiling and in the testing of multiple configurations of flow control devices for optimizing steam distribution.

Chevron is applying nuclear magnetic resonance technology to oil field applications in a best-in-industry laboratory in Houston, Texas, that was completed in 2015.

Chevron uses technology to monitor the effects of operations on the environment and the community. For example, we developed and deployed advanced airborne sensors and algorithms to measure methane in the atmosphere. We also deployed wave gliders during dredging operations at the Wheatstone Field in Australia to monitor real-time water data and impact on ocean water quality.


in the community

Wherever Chevron operates, the company strives to build lasting relationships to create prosperity now and for decades to come. We contribute to the economic and social well-being of the communities where we operate by creating jobs, supporting local businesses and training the workforce of the future. 

investing in education

Over the past three years, Chevron has invested more than $170 million in education partnerships and programs in the United States. We work with education organizations, government officials, nonprofit organizations and community leaders to create and strengthen education opportunities and offer career and technical training for students and workers. We invest in partnerships at every stage—from early education through employment—all with a special focus on cultivating programs in science, technology, engineering and math (STEM). 

Chevron supports a broad range of programs across the United States:

  • Chevron partners with the Fab Foundation to bring Fab Labs—fabrication laboratories—to areas where Chevron operates. The Fab Foundation provides access to tools and technology in order to educate, innovate and invent. The first Chevron-sponsored Fab Lab opened in 2014 at California State University, Bakersfield.

We also support Service to Opportunity programs focused on preparing residents and veterans for energy and manufacturing jobs in the region.

improving career and technical training

Chevron supports career and technical training programs that provide a foundation for long-term economic development.

In partnership with Casa de Amigos, Chevron supports the Take2 job skills program in the Permian Basin. The program helps equip low-income women and men with the skills to obtain high-paying jobs. From 2011 through 2015, Take2 participants experienced gross annual income increases totaling $4.1 million. 

Among a number of Gulf Coast initiatives, Chevron partnered with GNO, Inc., and Delgado Community College to use the annual Technical Skills Expo to introduce more than 800 high school students to industry opportunities, career pathways and training available at their schools.

Chevron sponsors the Contra Costa County Office of Education’s Regional Occupational Program (ROP). This program offers courses that provide free job training and equip residents with the skills to compete for well-paying jobs, including technical jobs at the Richmond Refinery. ROP courses help students develop strong communication skills, strengthen analytical skills, and learn how to work productively, both independently and as part of a team.  


record of achievement

Chevron’s story dates back to an 1876 oil discovery at Pico Canyon in the Santa Susana Mountains, north of Los Angeles. The find led to the 1879 formation of Chevron’s earliest predecessor, the Pacific Coast Oil Co.

Another part of our history begins with the 1901 founding of The Texas Fuel Co. (later Texaco) and its historic oil discovery two years later at Sour Lake, Texas. These companies and other members of the Chevron family have been instrumental in transforming the oil business into today’s global energy industry.

Throughout the 20th century, Chevron and Texaco experienced dynamic growth in the United States and internationally. In 1984, Standard Oil Co. of California, Chevron’s immediate predecessor, acquired Gulf Corporation in a $13.3 billion merger. At the time, it was the largest acquisition in corporate history. That same year, Texaco purchased Getty Oil and gained 1.9 billion barrels in proved reserves of crude oil and 2.8 trillion cubic feet of natural gas reserves.

Chevron and Texaco formed a number of partnerships, most notably Caltex Corp. in 1936. The 2001 merger of Chevron and Texaco was a natural outgrowth of a successful history of teamwork. In 2005, Chevron acquired Unocal Corp. In 2011, we acquired Atlas Energy, Inc., which added natural gas resources and shale acreage, primarily in southwestern Pennsylvania and northern Michigan.

health and safety

Chevron continues to demonstrate its commitment to advancing health initiatives, protecting the environment and promoting safety. We use our Operational Excellence Management System to systematically drive continuous improvement throughout our organization.

We are instituting a standard Contractor Health and Safety Management process across the company to help ensure that workers can do their jobs without risk to themselves, others or the environment and to help contract workers be aware of the safe work practices that apply to the work they are doing. For example, our San Joaquin Valley upstream business unit works with key contractors to raise their awareness about safeguards to prevent and mitigate incidents.  

Chevron was selected as the Best of the Best among the 2014 IHS SPECTRUM Excellence Award winners based on our innovative use of information systems to achieve environmental, health, safety and sustainability business goals.

Chevron ranked highest of all integrated oil and gas competitors in North America in the 2014 CDP S&P 500 Climate Change Report, with an overall score of 95 points. The score reflects Chevron’s transparency in disclosing our greenhouse gas emissions and our climate policies.  

In addition, our Piceance Basin operation, in northwestern Colorado, has initiated a multiyear research study of wildlife and habitat conducted by Colorado State University’s Warner College of Natural Resources.

In 2015, the Center for Offshore Safety awarded Chevron North America Exploration and Production its Safety Leadership Award in recognition of the Greater Gulf of Mexico’s Field Competency Program. Chevron was the only operator to receive the award, which recognizes outstanding contributions by an operator to improving safety management and sharing that knowledge with the industry.
