Considerations of Well Cementing Materials in High-Pressure, High-Temperature Conditions (RESEARCH NOTE)
As worldwide demand of hydrocarbon is growing fast, the oil and gas companies have been forced to explore reservoirs with more hostile conditions, such as high-pressure, high-temperature conditions. Improved technology, material selection and testing procedures are required to overcome the common problems in these conditions. One of the main phases of well construction is cementing job. Appropr...
متن کاملHigh-Temperature Pressure Transducers
Pressure sensing systems operating at temperatures >200 °C are required for a variety of presentand next-generation applications ranging from oil field instrumentation to turbine engine control. Quite often, part or all of the sensing system must be physically removed from the hightemperature environment. In some cases, pressure translating devices and capillary tubes are used to isolate the se...
متن کاملHigh-pressure – High-temperature Synthesis of Na6MnO4
Z. Naturforsch. 2009, 64b, 487 – 490; received February 20, 2009 The title compound has been synthesized under 4 GPa and at 500 ◦C from Na2O and MnO as starting materials. Rietveld refinement of the X-ray powder pattern indicates that Na6MnO4 is isostructural to Na6ZnO4 and thus is representing the second manifestation of an “isolated” [MnO4]6− anion after Na14Mn2O9. The compound crystallizes i...
متن کاملEffects of hydrostatic pressure and temperature on the AlGaN/GaN High electron mobility transistors
In this paper, drain-source current, transconductance and cutoff frequency in AlGaN/GaN high electron mobility transistors have been investigated. In order to obtain parameters of exact AlGaN/GaN high electron mobility transistors such as electron density, the wave function, band gap, polarization charge, effective mass and dielectric constant, the hydrostatic pressure and temperature effects a...
متن کاملCHEMICAL REACTION AT HIGH TEMPERATURE AND HIGH PRESSURE VI Polymorphic Transition in ZnP, at High Temperature and High Pressure
:1 new pressure-induced modification of zincdiphosphide, ZnP2, has been prepared by the di reel union o(zinc with phosphorus and also through the polymorphic transitions of both monoclinic and tetragonal ZnP2. The application of pressures above 20 kb combined with temperatures above 150'C is required for [be synthesis. The new modification of ZnP2 has a pseuda•cuhic cps[al symmetry with a latti...
