... the quality of an electronic circuit board, it is recommended in this paper to follow the guidelines and specifications of the Institute of Printed Circuits to certify the robustness of the design. Finally, the proposed DVP is thoroughly exercised on the insulation monitoring PCB under the prescribed test...

... vacuum-insulated tubing (VIT), active heating using electrical heating elements inside the well tubing, jet pumps using water as a power fluid, and downhole injection of paraffin inhibitors. In the field cases studied, none of these measures is 100% effective in preventing wax deposition. Mitigation...

...J. H. Azzola; D. P. Tselepidakis; P. D. Pattillo; J. F. Richey; S. J. Tinker; R. A. Miller; S. J. Segreto Summary Vacuum-insulated tubing (VIT) has been used successfully to mitigate the potentially harmful effects of annular pressure buildup (APB). In a recent deepwater installation, the subject...

...J. T. Finger; R. D. Jacobson; A. T. Champness Summary The Geothermal Research Dept. at Sandia Natl. Laboratories, in collaboration with Drill Cool Systems Inc., has worked to develop and test insulated drillpipe (IDP). IDP will allow much cooler drilling fluid to reach the bottom of the hole...

... on the thermal performance of subsea equipment such as wellheads, tubing and flowline jumpers, and flowline field joints. In contrast to previous published studies on the thermal performance of insulated subsea wellbores and flowlines, this paper addresses the thermal performance of the subsea equipment that can...

... of inhibitor injection systems used in deepwater completions and during testing of deepwater exploration wells will be reviewed. The benefits of insulated tubing to enhance inhibition design will be discussed. Also, a method will be introduced that can be used to estimate the maximum inhibitor injection rate...
