Meet the exact needs and goals of your data acquisition program with the readily customized MDT modular formation dynamics tester system. In one trip, you get the representative data you need for timely decisions:
The MDT wireline formation tester makes real-time flowline resistivity measurements at the probe module to discriminate between formation fluids and filtrate from water- and oil-base muds. Formation fluid is excluded from the sample chamber until a sample with an acceptibly low level of contamination can be recovered.
To collect virtually contamination-free formation fluids in substantially less time than it takes with a conventional probe, Quicksilver Probe focused fluid extraction is used with the MDT formation tester system. In conjunction with DFA, the quicker collection of more-representative samples for gives you a real-time understanding of hydrocarbon properties at reservoir PVT conditions while the MDT system is still in the borehole to avoid extended production testing or lengthy additional PVT laboratory work.
For challenging environments as varied as low-permeability or unconsolidated formations, heavy oil or near-critical fluids, and rugose boreholes, Saturn 3D radial probe technology employs multiple, self-sealing probes to circumferentially extract pure reservoir fluids and conduct pressure and permeability measurements. With a total surface flow area of 79.44 in2—a 1,200% increase over the largest conventional single-probe formation tester—Saturn 3D radial probe technology extends wireline formation testing to previously inaccessible fluids and reservoirs conditions.
The modular design of the MDT tool makes it easy to meet the exact needs and goals of your data acquisition program. Flexibility is designed in for compatibility with almost all Schlumberger measurement technologies. Modularity also enables evolving the MDT tool as new measurement techniques, technologies, and options are developed.

Analyze formation fluid as samples are flowed to the MDT tool to capture single-phase samples and differentiate oil types.
Limit pressure drawdown during fluid extraction and sampling to obtain critical data for optimized well tests and facility design.
Increase the length scale by obtaining permeability and anisotropy away from the wellbore to better understand reservoir heterogeneity.
