Openhole MDT Sample Transfer Equipment

Overview Library

Custom-designed heating and agitation system for restoration and pressurized transfer of MDT samples

MDT modular formation dynamics tester sample transfer equipment is used to safely recombine the liquid and gas phases of hydrocarbon samples retrieved from an open hole with the MDT 250-cm3, 450-cm3, 1-galUS, or 2.75-galUS sample chambers. The MDT chamber is fitted to the equipment, where it is repressurized, heated, and agitated to restore the sample to reservoir conditions prior to sample transfer or subsampling.

The electronically controlled heating jacket provides even, indirect heating through a liquid-filled annulus. The sample chamber is heated to transfer temperature in less than one hour, and the temperature is controlled at ±1.8 degF [1 degC].

The transfer unit, which has a working pressure of up to 30,000 psi [207 MPa], is equipped with dedicated high-pressure hoses suitable for all transfer fluids and a validation manifold for measuring bubblepoint pressure of the hydrocarbon sample at ambient temperature, reservoir temperature, or both.

Use of MDT equipment improves the quality and safety of the sample reconditioning and transfer process while saving time and money.
