Abstract Granular bed filtration is one of the processes under development for separation of fine dust at relatively high temperatures and pressures, for application in coal based combined cycle power plants. Bharat Heavy Electricals Limited (BHEL) have installed a test facility to evaluate the performance of a Circulating Bed Granular Filter (CBGF).

Abstract Casing is designed to provide well bore stability and withstand imposed loads such as external pressure, internal pressure and mechanical load due to compressive forces on casing. To ensure integrity and reliability of casings, a cost effective approach is hereby presented using finite element (FE) methods.

Abstract When drilling wells in HTHP fields, the drilling fluid properties are of utmost importance. The difference between fracture and pore pressure, expressed as the hydraulic window, can be quite narrow. One of the remedies for making sure that one stays within this hydraulic window, is to design a drilling fluid with very low ...

Abstract With the development of drilling in deep water areas, chemical treatments encounter more and more challenging operational conditions, including high temperature (>300°F), high pressure (>5,000 psi), and high salinity (>100,000 mg/L) as well as potential seawater breakthrough due to waterflood operations.

Overpressure strongly influences gas migration and trapping in deep high-temperature/high-pressure (HTHP) reservoirs. However, its time-dependent evolution is commonly poorly constrained by direct, quantitative pressure proxies. Here we combine quantitative Raman spectroscopy and microthermometry of fluid inclusions with 1-D burial–thermal modelling to
