What Production Optimisation Is

Production optimisation is the routine work of getting the most value from the wells and facilities you already have, within safe operating limits. It does not add new reserves by drilling. It closes the gap between what the system could deliver and what it does deliver, and it does this at the lowest cost and risk.

The word "most" needs care. The goal is usually maximum value, not maximum rate. Producing a well harder can bring sand, water or gas into the well earlier, damage equipment, or reduce the oil finally recovered from the reservoir. A good optimiser always asks: "More production today — at what cost tomorrow?"

Optimisation is a cycle, not a project. The team watches the system (surveillance), finds where production is lost (analysis), chooses and carries out a fix (action), and then checks the result. Then the cycle starts again, because wells and reservoirs change every day.

Short-term and long-term optimisation

Short-term optimisation works in hours to weeks. It uses the equipment as it is: adjusting chokes, set points, gas lift allocation, pump speed and well routing. It is cheap and fast, and it is mostly the work of operations and production technologists.

Long-term optimisation works in months to years. It changes the system itself: well interventions, new compression, larger flowlines, a change of artificial lift method, or a new water handling train. It needs budget, engineering and approval, and the asset team ranks these opportunities against each other.

Example. On an onshore field, the night shift sees that five gas lift wells share a limited supply of lift gas. Re-allocating the gas between them gives 150 barrels per day more oil the same week — a short-term gain. The same review shows that the lift gas compressor is too small for the field's future water cut. A new compressor stage becomes a long-term opportunity in the asset plan.
