Continuous Improvement Philosophy Results in 50Time Reduction to Sidetrack in the Shallow Oil Zone,Elk Hills Field

摘要

Continuous improvement measured in time savings required to sidetrack and redrill 133 shallow wells is documented.Time savings and a learning curve are related to decision making through a catalogue of sequential,applied techniques. Paralleling the evolution of applied techniques at the wellsite, bit and reamer technology evolves.Steer and ream while drilling tools(SRWD)evolve and make the sidetrack program viable.The confluence of geology,reservoir character as well as existing/new technology and management philosophy results in forecastable,positive changes.The incremental improvements produce a multi-year sidetrack program to successfully exploit the mature Elk Hills oil field.
