WebAug 27, 2024 · Flowline Temperature. The temperature gradient in the transition between normal and abnormal pressure zones often increases to about twice the rate of the normal temperature gradient. Increases of the mud temperature at the surface can also indicate the top of an overpressured section. Consideration must be given to circulation times, trip ... WebThe innovative tool architecture of PressureXpress-HT service provides the superior thermal stability of a quartz gauge and enables extended holding time: 14 h at 450 degF. The dual-flask design protects the electronic components from high temperatures. The HPHT Quartzdyne gauge is in one of the flasked sections, which also isolates it from ...

WebJun 2, 2014 · During the last decade, however, direct electrical heating (DEH) has emerged as an attractive alternative. DEH controls the flowline temperature to maintain it above the critical threshold for hydrate formation. By heating the flowline electrically, the need for chemical injections is reduced considerably. WebDec 1, 1995 · Summary. This paper is a case history of a deep, high-temperature, high-pressure (HTHP) well, drilled in the U.K. sector of the North Sea. The topics covered include the use of a vertical seismic profile (VSP) ahead-of-the-bit prediction combined with measurement-while-drilling (MWD) information to assist in picking a critical casing point. … cycloplegics and mydriatics
