Optimizing drilling parameters and drill bit design boosts ROP by 37% in Algerian field

摘要

DRILLING CHALLENGES IN the Hassi Messaoud (HMD) oilfield of Algeria have proven to be equal to the magnitude of its production. Historically, wells drilled in this field were vertical, moderate borehole diameters having a long 12 1/4-in. section. In order to increase production and gain a better understanding of the reservoir, Sonatrach Drilling engineering moved to moderately deviated, large-diameter boreholes delivering 1,000 m of drain in the reservoir.
