..., and measurement of the strain is performed by switching to an encoder when the deformation becomes large. The control of the back pressure corresponding to the internal pressure, external pressure, and pore pressure is operated by syringe pump. The servo motor is connected to the syringe and the processes...

.... When gas hydrate is melted, gas bubbles would be created in the soil. The purpose of this study is to investigate what would happen to fine grained, clayey soils when gas bubbles expands. A triaxial cell was modified and used to consolidate the sample under a high back pressure, 981 kPa. CO 2...

... was percolated into a host specimen at the rate of 0.5 MPa to 1.0 MPa per minute passing through the same pipe which water for back pressure goes into. The testing apparatus can be operated by a digital servo control system and has capabilities of 200 kN for axial loading, 20 MPa for confining pressure and 20...

... phase in case of oil wells and rich with gaseous phase in case of gas wells. Transportation of this fluid from well head to the processing facility is accomplished through pipelines. AS the distance of pipeline increases, the back pressure on well head increases due to pressure loss in pipeline...
