Landed well in sweet spot, eliminated pilot holes
The GeoSphere service mapped the reservoir, including its top, base, and
dip at distances up to 82-ft [25-m] TVD below the well path in real time. It
also detected the top of the reservoir 33-ft [10-m] TVD deeper than expected.
As a result, Apache maintained the trajectory before geostopping the section
10-ft [3-m] TVD above the reservoir top.
Eliminating pilot holes reduced drilling costs and managed risks while
also achieving Apache's goals and objectives in this complex geological
environment. The subsurface information recorded by the service during the four
landing operations will be used by Apache for further field
development.
