Horizontal drilling above a steamflooded reservoir

摘要

In the past two years, Macpherson Energy, through its operating company Macpherson Oil Company, has brought 56 wells into production using horizontal drilling in California's Round Mountain oil field, northeast of Bakersfield, and has expanded production from the field nearly threefold. This increase has come about while Kern County, where the field is located, has seen its overall oil production decrease from about 166 million bbl (455,000 bpd) in 2007 to 162 million bbl (443,000 bpd) in 2008 to 155 million bbl (425,000 bpd) in 2009, according to the state Department of Conservation.
