Restoring rate on mature Hassi Messaoud producers
Behind-casing saturation and remaining oil were mapped on a cluster of old onshore producers. Perforation and water-shutoff choices followed the logs, not the original completion drawing. The field returned a measurable oil rate without a full workover rig on every well.
Well Intervention and Integrity
Killing sustained casing pressure in a tight annulus
SCP on a producing onshore well had already failed a conventional squeeze. We diagnosed leak paths, selected a resin and placement method that could still enter at low injectivity, and left a barrier that held on the subsequent pressure test.
Well Construction
First oil on a pad while the plant was still being built
An onshore development needed production while permanent facilities were still catching up. Tubular running, completion, and surface tie-in were planned as one sequence so a temporary production system could take the well without rework.
Well Flow Management
Production log that stopped a useless restimulation
A Hassi Messaoud producer was making oil, but allocation between intervals was a guess. A production log showed which zones were contributing. The operator shut in the dead intervals and stopped chasing a stimulation that would not pay.
Completions
Unloading two onshore wells after completion
Two Hassi Messaoud wells sat loaded with completion fluid and would not flow. Access, barriers, and coil were sequenced in one campaign so both wells cleaned up and produced before the rig window closed.
Sustainable Well Solutions
A P&A that held on the first pressure test
An old onshore well needed plugs the regulator would accept, not a copy of the last abandonment on the pad. Cement, barriers, and records were written for that wellbore. The test passed and the next operator inherited a file, not a surprise.
