BP had substantial landing holdings across the Texas panhandle, which
encompassed a large part of the tight gas Cleveland formation. They began an infill-
drilling program of horizontal wells in the Cleveland formation starting in late 2003, and
are ongoing throughout 2004 and should continue into 2006. In 1999, BP considered this
area uneconomic by existing practices and was ready to sell or farm out their interests in the
area. BP desired to devise a plan, which would make this area economic by increasing
the reserves and rates of the new development wells. It was determined from data taken
from a well prior to the merger of Amoco and BP by a small company owned by Amoco
that horizontally drilling infill wells could achieve the purpose of bringing this asset base back to
economic acceptability within company. This report provides detailed analysis of the infill-drilling program up to August 2004:
to demonstrate the results of the program, the problems occurred by introducing horizontal drilling to an area that had never
drilled horizontal wells, and recommendations to improve the drilling
performance within this program.
