Update No. 15: Pennsylvania Incident

March 3, 2014, 6:00 p.m. EST – Over the last few days, Wild Well Control and Chevron conducted tests to assess the integrity of the Lanco 8H well, after previously capping the 7H and 6H wells. The testing included inspecting the seals on the well head and testing the integrity of the valves and ports. We then successfully installed a valve that shuts off the gas flow and replaced the wellhead on the Lanco 8H well. With the actions taken this weekend, all three wells on the Lanco pad are now secure.

Over the next several weeks, we will be installing plugs about 8000 feet below the surface in all three wells as an extra layer of protection to relieve any pressure on the wellheads. We are continuing to conduct our investigation into the cause of the incident in cooperation with the Pennsylvania Department of Environmental Protection and all appropriate regulatory authorities.

Update No. 14: Pennsylvania Incident

Feb. 25, 2014, 4:00 p.m. EST – Today at approximately 4:00 p.m., Wild Well Control successfully capped the second Lanco well, the 6H. At this time both wells are capped, stopping gas flow from the wells. These are significant milestones in our response efforts.

The next step is for Wild Well Control to assess the integrity of the 8H well. The integrity testing involves inspecting the seals on the well head as well as testing the integrity of the valves and ports. Once we have diagnostics from the testing, we will begin planning the path forward and complete any repairs, if necessary, to secure this final well.

The continuing well intervention efforts involve many steps and must be executed in a precise, controlled, and methodical manner. We are working to be efficient in our efforts; and the safety of the workers and operations will determine the appropriate pace.

Once it is determined that the 8H well is also secure, a thorough investigation to determine the cause of the incident will begin.

Air samples were also taken and were consistent with readings at a Pennsylvania DEP air quality station in Washington, PA. Air sampling will continue during the duration of the response activities.

Update No. 13: Pennsylvania Incident

Feb. 23, 2014, 3:30 p.m. EST – Today at 2:25 p.m., Wild Well Control successfully capped Lanco well 7H, stopping gas flow from the well.

The next step of the process is for WWC to conduct similar procedures on well 6H. This is expected to occur in the next few days. After that, WWC will assess the integrity of the 8H well and complete any necessary repairs to secure the well. Part of the plan might involve flaring of the gas.

The continuing well intervention efforts involve many steps and have to be executed in a precise, controlled, methodical manner. We are working to be efficient in our efforts to minimize the duration however, the safety of the workers and operations will determine the appropriate pace.

Update No. 12: Pennsylvania Incident

Feb. 22, 2014, 12:30 p.m. EST – Wild Well Control (WWC) is completing preparations to safely secure the wells. They have performed diagnostics to test the integrity of existing lower well head sections of the 7H and 6H wells. The tests were positive, which means the new capping stack can be bolted securely to the existing lower section.

 

The next step will be for WWC to cut the well heads and seal the wells with a capping stack beginning with the 7H well. The cutting operation on the upper portion of the well head will allow the capping stacks to have clear connection points. To do this, WWC will use specialized equipment that creates a high-powered stream of water and sand to cut through the upper assembly of the wellheads.

 

WWC will connect the new capping stacks to the lower section of the wellheads while the wells are flowing. This is a critical step in the operation in the effort to secure the well.

 

The cutting and capping operations are planned to occur during daylight hours because of the potential noise impact, but it is possible that operations may continue into the night. We expect cutting and capping to last one day for each well.

 

The section of the 7H wellhead where the leak occurred will be transported offsite for further analysis by an independent third party as part of the ongoing root-cause investigation.

 

Following the capping of the 7H and 6H wells, WWC will assess the integrity of the 8H well and complete any necessary repairs to secure the well head equipment. This work should be completed in one day.  Once this occurs, the well head equipment of all three wells on the Lanco “A” pad will be secured and all gas flow will be stopped.

 

WWC will install plugs as protective barriers approximately 8,000 feet below the surface in all three wells to prevent gas pressure from reaching the well head. This down-hole intervention involves several steps and should take approximately four days per well to complete.

 

Portions of these processes may involve flaring of gas.

 

These well intervention efforts involve many steps and will be executed in a precise, controlled, and methodical manner. We are striving to be efficient in our efforts to minimize the duration of the operations, however, the safety of the workers and operations will determine the appropriate pace.

Update No. 11: Pennsylvania Incident

Feb. 20, 2014, 3:17 p.m. EST – It is with heartfelt sadness that we learned from the Pennsylvania State Police that investigators from their forensic services unit located remains at the Lanco well pad site yesterday. Our thoughts go out to the family, friends and co-workers of the missing worker, Ian McKee.

We value our employees and contractors as our greatest asset and work extremely hard every day to prevent incidents like this. We are committed to fully understanding what happened and are determined to prevent this from happening again. 

Chevron and Wild Well Control personnel are working collaboratively to design and execute our well intervention plan to control the wells on the Lanco pad.

We were successful in installing the diversion tube on Wednesday, a device that directs gas away from the well head area allowing Chevron and Wild Well Control personnel access to safely access the well head. The plan at this time is to cap 7H, then 6H, and to then run diagnostics on 8H to determine the best path forward.

The next step of the process includes cutting and unbolting part of the upper portion of the well head so that the blowout prevention equipment [or capping stack] has a clear connection point. We will utilize specialized equipment that creates a high powered stream of water and sand to cut through the upper assembly of the well head. Weather permitting; this work is planned to begin this weekend and could last several days.

Due to the pressure needed to pump the water and sand in a jet like fashion, this process has the potential to be loud.  Abrasive water-jet cutting is the safest cutting method in potentially flammable atmospheres because it is self-cooling and provides no ignition source.

Part of the plan might involve flaring of the gas. We ask residents not to be alarmed if this occurs as this is expected under these conditions.

These well intervention efforts involve many steps and have to be executed in a precise, controlled, methodical manner. We are working to be efficient in our efforts to minimize the duration however, the safety of the workers and operations will determine the appropriate pace.

Any questions regarding Mr. McKee should be directed to the Pennsylvania State Police or Cameron International.

Update No. 8: Pennsylvania Incident

Feb. 17, 2014, 4:55 p.m. EST – For clarification regarding the timeline associated with the Lanco Well Site Fire – the initial well, 7H, began burning the morning of February 11. An adjacent well on the pad, 6H, began burning on February 14, after sustaining damage from the heat of the fire from the initial well. The two wells are no longer burning as of 3PM Saturday. 

It is premature to speculate on what caused the flames to go out. However, we do know at this time the volume of natural gas is lower than what it had been previously.

Due to the flames going out, Wild Well Control was able to access the well pad to perform an assessment of the wellhead equipment on Sunday. The information gathered allows our planning engineers to have the latest and most accurate information readily available to assist with their intervention. Wild Well Control is also mobilizing blowout prevention equipment, such as capping stacks, to seal the wells, which is standard equipment for these types of situations.

Before the well intervention equipment work can commence, a crane that was burned as a result of the fire must be removed from the site. The crane, that is approximately 30 feet from the well head, required special equipment to be brought in to assist with its removal.

Water tanks have been moved onto the Lanco well pad to prepare for well intervention work and fire prevention and suppression, if necessary. We are currently connecting all of the tanks together and filling them with fresh water. We have mobilized a fleet of tanks that hold 500 barrels of water each, with an approximate capacity of 21,000 gallons per tank. The purpose of these tanks is to provide enough water to cool the area and minimize the potential for re-ignition.

We are staging additional response equipment at nearby locations, including the Greene County Fairgrounds.

On Sunday, Chevron met with DEP representatives at the Incident Command Center in Moon Township for a Technical Briefing on the well intervention plan. Chevron continues to work cooperatively with local, state and federal agencies and emergency response organizations. We appreciate their ongoing support to this incident.

A weather station is in place on site to provide accurate, current on-site weather conditions for monitoring by the Incident Command Center to assist with operations planning.

We are dedicating considerable resources to maintaining and clearing the roads due to weather conditions to help assist personnel traveling to the site and equipment being delivered.

Incident command and response teams continue to work 24 hours a day to assess and respond to the incident and to help protect the safety of all involved in responding to this incident.

Update No. 7: Pennsylvania Incident

Feb. 16, 2014, 5:08 p.m. EST – The two wells are no longer burning as of 3PM Saturday. It is premature to speculate on what caused the flames to go out. However, we do know that at this time, there is not enough fuel being emitted to sustain combustion, and with the cooling of the crane, the ignition source has been removed.

Before the well intervention equipment work can commence, a crane that was burned as a result of the incident must be removed from the site. This crane was in the line of fire and is badly damaged, so special equipment was brought in to assist with its removal. The removal of the crane is necessary before we can begin well intervention work.

One of our top priorities continues to be staging water near the site to prepare for well intervention work and for fire prevention and suppression, if necessary. Ten water storage tanks were delivered and installed on Friday, and one tank was installed on Saturday. Additional tanks were able to be installed Sunday as well. Our focus will soon shift to connecting all of the tanks together and then filling them with fresh water. 

Water from these tanks will be used to cool the well site and equipment, if necessary, so the wells can safely be worked on and for potential fire prevention and suppression. The water tanks are being placed on a tank pad that Chevron constructed adjacent to the well pad. Weather permitting, we hope to source water around the clock. We are staging additional response equipment at nearby locations, including the Greene County Fairgrounds.

Chevron continues to work with local, state and federal agencies and emergency response organizations. We appreciate their ongoing support to this incident.

We are dedicating considerable resources to maintaining and clearing the roads due to weather conditions to help assist personnel traveling to the site and equipment being delivered.

Update No. 6: Pennsylvania Incident 

Feb. 14, 2014, 4:40 p.m. EST – Activity continues on the Lanco well pad site, where the initial well is burning at a steady flow, as expected, and an adjacent well on the pad is burning intermittently. This second well sustained damage from the heat of the fire from the initial well. We continue to monitor the condition and integrity of the remaining well on-site and a contingency plan is in place should conditions change.

Chevron continues its operations of clearing the site of equipment and vehicles that were on the site at the time of the incident. This will allow Wild Well Control to get close enough to the well to perform its operations. The last piece of equipment to be removed from the site is a charred crane. This crane is maintaining extreme temperatures and is the ignition source that continues to reignite the natural gas flowing from the initial well. This flame is serving as the source of ignition for the second well. The flames have prevented the combustible gas from spreading beyond the well site. The crane is being moved to allow access for the well intervention equipment.

Staging water near the site in preparation for firefighting is a top priority. Toward that end, water trucks, heavy lifting equipment and pumping systems are being delivered to the site. Additional response equipment is being staged at the Greene County Fairgrounds and other locations near the well site. Chevron has constructed a water tank pad adjacent to the well pad, approximately 155 feet by 185 feet, so that water can be stored on site and used to fight the fire.

Activity at this point has been focused on ensuring that Wild Well Control has the space, resources, conditions and equipment on-site and in place to safely begin its operations to gain control of the well and stop the flow of natural gas. We continue to monitor the air, surface waters and noise in the area for any signs of impact. Fixed, portable and personal gas monitors and alarms have been deployed on-site and in the surrounding areas. Air and water samples are being collected and sent to labs for analysis.

Chevron continues to work with local, state and federal agencies and emergency response organizations. We appreciate their ongoing support to this incident. Incident command has been staffed with dedicated resources since the incident took place. Response teams continue to work 24 hours a day to continue to assess and respond to the incident. We are working at a pace that helps ensure the safety of all involved in responding to this incident.

Neighbors may call a Chevron toll-free line with any questions: 1-877-847-8408.


Update No. 5: Pennsylvania Incident 

Feb. 13, 2014, 9:00 p.m. EST – Chevron has had a full day of on-site operations to move our plan forward to extinguish and cap the well. The water tank pad has been prepared and the site is expected to be ready for water tanks to be delivered on Friday, weather permitting. We expect additional equipment will be removed Friday, which will safely enable clear access to the well. Chevron, Wild Well Control and partners continue to make progress in planning for the removal of machinery from the incident site. 

The fire is currently an intermittent flame sourced by natural gas from the initial well. While progress has been made today responding to conditions at the well site, we remain focused on the unaccounted for contractor. Chevron continues to work with local, state and federal agencies and emergency response organizations. We appreciate their ongoing support to this incident.

Out of an abundance of caution, we continue to monitor the air, surface waters and noise in the area for any signs of impact. Fixed, portable and personal gas monitors have been brought on site to aid responders. At this point we have no indications that this incident has created any safety risk. 

Incident command has been staffed with dedicated resources since the incident took place. Response teams continue to work 24 hours a day to continue to assess and respond to the incident.
