More than 140% oil production raised using Saltel Patch

Context

oil production raised using Saltel Patch

The client, one of the largest independent oil company, expected to shut off 7in casing perforation sets producing gas, over 15 wells on an onshore oil field in a remote area in Central Africa.

The Gas produced was originally used for artificial lift purpose (Natural Gas Lift & Artificial Gas Lift) and the client decided to switch artificial lift method from gas lift system to Sucker Rod Pump (SRP) system. For this, they required Saltel Patches in 15 wells, to shut off casing perforations, which were producing gas from the Turonian formation.

Solution

Fifteen 7in Slimline patches, with variable lengths (adjusted locally) as per client needs.
A 14-month campaign completed in 5 mobilizations.
