(2009-05-15)In order to keep up with the world’s energy demands, oil and gas producing companies have taken the initiative to explore offshore reserves or drill deeper into previously existing wells. The consequence of this, however, ...
-
(2014-09-05)A Chandler 7600 Ultra HPHT Viscometer was setup to imitate well bore conditions of high pressure, high temperature wells, and the research objective was to investigate the reaction of Class H cement with 35% silica and ...
-
(2012-11-15)In the life of a well, the cement sheath not only provides zonal isolation but also supports casing and increases casing-collapse resistance. Due to the high-pressure, high-temperature (HPHT) conditions, the cement sheath ...
-
(2014-12-15)Annulus Pressure Buildup (APB) is one of the major design considerations/problems for deepwater wells. APB is even more problematic in High Pressure/High Temperature (HP/HT) wells. High flow rates could potentially worsen ...
-
(2012-02-14)Modeling the performance of high-pressure, high-temperature (HPHT) natural gas reservoirs requires the understanding of gas behavior at such conditions. In particular, gas viscosity is an important fluid property that ...
-
(2013-12-06)Ilmenite (FeTiO_(3)), with a mean particle size of 30 - 45 µm, was first introduced into the oil industry as weighting material in 1976. However, its use was limited mainly because of its abrasiveness to drilling equipment. ...
-
(2016-08-09)Drilling teams face several challenges when operating in high-pressure, high-temperature (HPHT) fields, such as lost circulation and difficulties in well control. One way to address these issues is to fully understand the ...
-
(2018-12-04)The scarcity of conventional oil reservoirs has led the oil and gas (O&G) industry to develop non-conventional extraction techniques such as extended-reach drilling (ERD) that brings new engineering challenges. Challenges ...
-
(2012-11-12)Down-hole damages such as borehole collapse, circulation loss and rock tensile/compressive cracking in the open-hole system are well understood at drilling and well completion stages. However, less effort has been made to ...
-
(2019-07-15)Iron sulfide scales of different forms exist in sour oil/gas-producing wells as well as seawater injection wells. Traditionally, they are dissolved using HCl and other inorganic acids. In the past decade, a tetrakis ...
-
(2017-06-30)The scope of this research is to study the rheological behavior of an oil based mud (OBM) sample from the Mexican side of the Gulf of Mexico (GOM) under extreme conditions of High Pressure High Temperature (HPHT). In the ...
-
(2020-04-13)Drillers dedicate many hours to well control training, where they learn how to identify a kick by looking at drilling parameters and comparing them to the planned values. In HPHT wells, UBD and other advanced drilling ...
-
(Texas A&M University, 2007-09-17)Estimation of viscosities of naturally occurring petroleum gases provides the information needed to accurately work out reservoir-engineering problems. Existing models for viscosity prediction are limited by data, especially ...
