Identification of problem

A client in Angola, Africa, was experiencing excessive water production from the lower zone of 2 separate subsea wells with open-hole gravel pack completions.

Issues to overcome

The 2 wells had different completion sizes and the operator wanted to utilize the same size tool for both wells. The first well had a 5” OHGP assembly inside 9 ½” open-hole and the second had a 5 ½” OHGP assembly inside 8 ½” open-hole.

Application

Rigless interventions were performed, running a Wel-lok™ WSO from a TLP on e-line and set inside the base pipe of each well, sealing through the base pipe and gravel pack screen and mixing with the proppant out to the open-hole formation.

Outcomes/Conclusion

Initial results reported by the client is that each well has at least doubled the oil production and significantly reduced the water cut.

About the application

The Wel-lok™ WSO (Water Shut Off) has been specifically developed to reduce unwanted water production from wells with sand screen and open hole gravel pack completions (OHGP). Unlike any other solution on the market, the Wel-lok™ WSO tool seals the annulus and the wellbore in one operation without the need to perforate the sandscreen or squeeze the alloy into the open hole annulus. The melted alloy fills inside the completion and in the annulus to form a metal to metal sealing solution that is seamless, significantly reducing unwanted water production.
