Wellbore Cleanout in Inclined and Horizontal Wellbores – The Effects of Fluid Rheology, Inclination, and Solids Density.
(2019-08-30)
Recent technical improvements in the drilling process have allowed drilling of high inclination and horizontal wells with longer laterals. The frequency of such wells has increased over time due to their advantage of ...
Three-dimensional fully coupled thermoporomechanical modelling of fractured reservoir rock
(2019-05-10)
The coupled behaviors of fluid flow, heat transport and geomechanics in fractured porous media are studied. Emphasis is placed on the coupled hydro-mechanical processes involved in hydraulic fracture propagation, thermal ...
STUDY OF FLUID DYNAMICS EFFECTS FOR LOSS OF WELL CONTROL INCIDENTS IN SUBSEA WELLS
(2019-05-10)
The safety of well operations has become the focal point of the research paradigm since the Deepwater Horizon incident. The risks of wellbore blowouts cannot be neglected in any drilling operation, which makes the discharge ...
EXPERIMENTAL AND MODELING STUDIES ON AXIAL OSCILLATION-SUPPORTED DRILLSTRINGS
(2019-05-10)
Extending the reach of high-angle and extended-reach wells through slide drilling operations are hindered by high downhole friction (static and dynamic), which emanates to inefficiencies, such as poor weight transfer from ...
Laboratory Characterization of Reservoir Stimulation and Heat Extraction with Application to EGS
(2019-12)
Enhanced or engineered geothermal systems (EGS) could enable extraction of significant geothermal energy from hot relatively dry rock reservoirs. However, issues related to reservoir creation in different type of rocks and ...
DRAINAGE BEHAVIOR OF AQUEOUS, POLYMERIC, AND OIL-BASED NITROGEN FOAMS: THEORETICAL AND EXPERIMENTAL INVESTIGATION
(2019-08-01)
Foams can be formulated to have a wide range of densities and viscosities. This unique behavior makes foam suitable for underbalanced drilling where pressure exerted on formation is maintained below pore pressure and at ...
Downhole Geothermal Power Generation in Oil Wells
(2019-12-13)
Sustainable production of sufficient energy to power the world’s economies with minimum environmental footprint have been one of the most significant challenges for decades. As an essential type of alternative energy, ...
THE EFFECT OF PORE SPACE ON FLUID FLOW AND PHASE BEHAVIOR IN TIGHT FORMATIONS
(2019-05)
Unconventional resources have led to a new abundance of natural oil and gas supply all over the world over the past decade and are expected to play a vital role in the future of this industry. Despite tremendous growth of ...
BARITE SAG UNDER DYNAMIC AND ELEVATED TEMPERATURE CONDITIONS: EXPERIMENTAL STUDIES AND MATHEMATICAL MODELING
(2019-05-10)
Barite sag is an undesired occurrence that causes density variation in the wellbore. It is a problem that is related to both fluid property (mainly rheology) and drilling practices, and it arises mostly in invert emulsion ...
UNDERSTANDING THE FUNDAMENTAL DRIVE MECHANISMS FOR HUFF-N-PUFF ENHANCED OIL RECOVERY IN TIGHT FORMATIONS
(2019-12-13)
Unconventional oil and gas resources have recently become the major source of produced hydrocarbons in the US. The change in the energy landscape follows nearly two decades of technological breakthroughs including horizontal ...
