The Sapesco Positiive Displacement (SDS) bottom hole sampler provides for the taking of representative reservoir fluid samples. The sampler can also be operated to take Single Phase Samples (SPS) from which samples are maintained at a pressure above the reservoir pressure, back to the PVT laboratory. Samples, when analysed, provide data vital for the economic and technical evaluation of the reservoir.
The sampler is run on wire line (slick or electric) and can be triggered by a mechanical firing device or surface firing via and electric line. Multiple samplers can also be run simultaneously.
For transportation of samples, a range of cylinders (700 ml) can be supplied with pressure ratings of 5,000, 10,000 and 15,000 psi. For the USA market, DOT-approved cylinders are also available.
