Slim tool taxis facilitate logging a highly deviated 6” hole section on wireline
KOC needed to acquire petrophysical and reservoir data in a highly deviated 6”wellbore section. Conveying wireline tools via 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 Schlumberger 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 drag on wireline tools can be reduced down 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 pretesting tool was deployed in one run and tool reached TD effortlessly. Data quality was devoid of stick-slip and no sticking observed during extensive pre testing.

CHALLENGE
High deviation wireline logging in 6” wellbores without resorting to PCL.
SOLUTION
Petromac’s Slim Tool Taxis and conveyance expertise enable designing toolstrings with ultra low friction.
RESULTS
World record deviation of 72° achieved in the first attempt in Kuwait with a TripleCombo-Pressure Express Toolstring.
