HOUSTON – Schlumberger has introduced the Saturn 3D probe as the newest module for the MDT formation dynamics testing tool. The Saturn now can get pressure measurements and fluid samples from reservoirs that previously could not be sampled.
“Whether the reservoir is unconsolidated, has low permeability, or contains heavy oil, we can now perform pressure measurements and downhole fluid analysis and bring high-quality samples to surface,” said Catherine MacGregor, president, Schlumberger Wireline.
In field applications, the Saturn probe has successfully sampled fluids as low as 7º API from unconsolidated formations with unconfined compressive strength as low as 300 psi. In the Middle East, Saturn sampled fluid in formations with mobility less than 2 mD/cP.
The Saturn probe has four elliptical suction probes mounted at 90º intervals circumferentially around the tool, providing the largest surface flow area of any probe in the industry—more than 500 times that of a standard probe, according to Schlumberger.
