Abstract: A technique facilitates formulation of predictions regarding the run life of a pumping system. Based on the predicted run life, and factors affecting that predicted run life, corrective actions may be selected and implemented. The corrective actions may involve adjustment of operational parameters regarding the pumping system so as to prolong the actual run life of the pumping system. The technique utilizes an algorithm which combines various models, e.g. physical models and degradation models, to provide various failure/run life predictions. The various models may utilize a variety of sensor data, such as actual sensor data and virtual sensor data, to both evaluate the state of the pumping system and the predicted run life of the pumping system.

Abstract: A reverse circulation debris cleanup tool has a pressure control valve that closes up a passage through the body based on a sensed well condition to help pressure control the well when rams close around the tool to isolate the surrounding annulus. The sensor can hold the valve open for a predetermined time to allow debris removal operations and then close. The debris chamber below an eductor in a VACS tool can be thousands of feet long and the valve can provide protection during running in or removal of the tool from well pressure events so as to avoid using shear rams and losing the bottom hole assembly in the borehole and a fishing operation to get it out.

Abstract: An integrated system is disclosed to handle production of multiphase fluid consisting of oil, gas and water. The production stream is first separated into two streams: a liquid dominated stream (GVF<5% for example) and a gas dominated stream (GVF>95% for example). The separation can be done through shrouds, cylindrical cyclonic, gravity, in-line or the like separation techniques. The two streams are then routed separately to pumps which pump dissimilar fluids, such as a liquid pump and a gas compressor, and subsequently recombined. Both pumps are driven by a single motor shaft which includes an internal passageway associated with one of the pumps for reception of the fluid from the other pump, thereby providing better cooling and greater overall efficiency of all systems associated therewith. A method for providing artificial lift or pressure boosting of multiphase fluid is also disclosed.
