New drilling process increases rate of penetration, footage per day

摘要

ExxonMobil has developed a new approach to drilling optimization, called the ExxonMobil Fast Drill Process (FDP), that uses real time analysis of the energy consumption of the drilling system to maximize the rate of penetration (ROP). Implementation of FDP has resulted in significant gains in drilling performance with instantaneous ROP increases of 100-400% and increases in footage per day including trips and connection time by 30-100%. Similar results have been observed in soft and hard formations, low and high angle wells, and with all rig types. Improvements continue to be observed in the most mature implementations. Operators' drill rate performance is difficult to assess objectively. The great majority of bits are evaluated based on their performance relative to offsets. However, drill rates are often constrained by factors that the driller does not control, and in ways that cannot be documented in a bit record. Consequently, drill rates may vary greatly between two wells running identical bits. The manner in which a bit is run is often more important than which bit is run.
