Case-Histories:

RX-72TL Brine Lubricant / Friction Reducer.

During a logging-operation at Sleipner, well B-17, MWS W/L recorded a pickup-weight = 1700 lbs at 3000m depth (with Ramex RX-72TL in the well).
After the well was produced, and Ramex RX-72TL was produced out of well, the pickup-weight increased to 2700 lbs, still using the same BHA and located at the same depth, 3000m.(59% increase in pickup weight)
This illustrates clearly that Ramex RX-72TL is very efficient during wireline-operations in long, highly deviated wells.

During two ea. identical Coil-Tubing operations at Statfjord, well C-18a, the friction factor was reduced from 0,27 to 0,17 and the only variable was the addition of 2 vol.% RX-72TL prior to the second RIH.
