new life for oil fields

Horizontal drilling is helping to enhance production and recovery from old oil fields. At the century-old Kern River Field in California’s San Joaquin Valley, horizontal wells drilled with steerable tools allow us to effectively access remaining oil, achieving higher production rates and greater recovery than vertical wells. Directional control is maintained within tight tolerances during drilling operations and logging tools allow us to monitor and react in real time when we’re deviating from the target formation. The result: We’ve significantly reduced Kern River’s decline, due to the higher production rates from horizontal wells.

Elsewhere in the San Joaquin Valley, horizontal drilling is achieving similar results. A good example is the San Ardo Field, where horizontal drilling is enabling us to increase production by improving drainage from the heated portions of a much thicker reservoir.
