Compact Production SamplerBottomhole sampling solution for productionlogging and slickline applicationsThe Compact Production Sampler is a mercury-free, positive-displacementbottomhole reservoir fluid sampling tool that captures conventional bottom-hole samples. It is electrically actuated and modular and can be integratedinto any Schlumberger production logging operation. The sampler uses exist-ing planned production logging interventions and thus eliminates the needfor a separate wireline intervention to collect reservoir fluid during real timeor memory production logging.

The sampler’s through-wired design allows the tool to be run in any sectionof the PS Platform* production logging string (slickline or electric line conveyed)or in any section of a memory production logging string that has eFire*electronic actuation capabilities. Its design allows a fullbore flowmeter tobe run simultaneously at the bottom of the PS Platform* production loggingstring. The sampler does not interfere with any existing tool configuration.

Because the system can be surface fired, there is no need to pull out ofhole to reset the time delay, and minimum downtime is required. The surfaceactuation is especially valuable in these two situations: � when bottomhole samplers are run on coiled tubing or wireline with

a tractor in horizontal wells � when actuation by time delay risks wasting time in the hole or requiring

a rerun if the tools do not reach the appropriate sampling depth beforethe sample is collected.

The small sample remains in the chamber, which incorporates an integralagitation device. The sample can be shipped for quick testing by the PVT Express onsite well fluid analysis service or for testing by one of the PVT laboratories in the Schlumberger global network.
