World Record: 6” wireline logging to 72° deviation in Kuwait

KOC needed to acquire petrophysical and reservoir data in a highly deviated 6”wellbore section. Historically, conveying wireline tools via drill-pipe was the only option, when faced with deviations over 60degrees in such wellbore sizes.

However, KOC is laser focused on rig efficiency and tasked the wireline provider and Petromac to provide a solution to deploy wireline tools by gravity. A slim tool taxi was designed, manufactured and deployed in record time.

Slim tool taxis were extensively tested and Petromac simulations showed that the wireline toolstring drag could be reduced to as little as 5%. Armed with this, the slim taxis were deployed for the first time in Kuwait to a record-breaking deviation of 72°. A triple combo plus pressure testing tool were deployed in one run and the tool reached TD effortlessly. Data quality was devoid of stick-slip and no sticking observed during extensive pressure testing.
