Numerical simulation of multiphase fluid flow in naturally fractured reservoirs.
(1983)A new mathematical flow model is derived for characterizing the multiphase fluid flow phenomenon in naturally fractured reservoirs. This model treats the reservoir as a double porosity medium consisting of a heterogeneous, ... -
Numerical simulation of nonlinear buoyancy waves in the lower atmosphere.
(1997)A 2D dry incompressible vorticity-stream function model is developed and used to investigate nonlinear buoyancy waves, especially internal solitary waves and related phenomena in the lower atmosphere. Using this model some ... -
Numerical simulation of pile geothermal heat exchanger with spiral tube considering its thermo-mechanical behavior
(International Ground Source Heat Pump Association, 2017)Pile geothermal heat exchanger (PGHE), which utilizes the building foundation piles as part of the geothermal heat exchangers (GHEs) for a ground-coupled heat pump (GCHP) system, has been attracting the interests of ... -
Numerical simulation of slinky-coil ground heat exchangers installed in railway tunnels
(International Ground Source Heat Pump Association, 2018)The use of horizontal ground heat exchangers (HGHEs) greatly reduces the initial cost of GSHP systems in comparison with vertical GHEs. Though the HGHEs are commonly used in North American countries, the installation number ... -
NUMERICAL SIMULATION OF THE EFFECTS OF RESERVOIR HETEROGENEITY, FRACTURES, AND MULTI-WELL INTERFERENCE ON PRESSURE TRANSIENT RESPONSES USING MULTISTENCILS FAST MARCHING METHOD
(2017-08-28)Analysis of rate and pressure transient responses of a well in spatially heterogeneous reservoir cannot be performed using conventional well-test analytical equations. An accurate analysis of transient pressure/rate responses ... -
Numerical simulation of transient cuttings transport with foam in horizontal wells
(2013)The use of foam for underbalanced drilling applications is increasing significantly. This is because foam exhibits properties, which are desirable when drilling depleted and low-pressure wells. However, a good knowledge ... -
Numerical simulation study on CO2 injection for enhancing hydrocarbon recovery and sequestration in tight oil formations
(2014)Hydrocarbon resources from unconventional reservoirs, especially tight/shale plays, are changing the North America's energy prospect. Single digit percentage of oil shale recovery with current best practices, leaves a large ... -
Numerical simulations of cyclic storm behavior: Mesocyclogenesis and tornadogenesis.
(2003)Building upon previous work that examined the dynamics and model sensitivity of cyclic mesocyclogenesis, this study uses idealized numerical simulations to investigate the cyclic redevelopment of vertical vortices in ... -
Numerical Simulations of Fracture Propagation Applied to Petroleum and Geothermal Reservoir Using Finite Element Method
(2015-08)Hydraulic fracturing is a major technique in reservoir stimulation to enhance production. Better understanding of mechanisms of hydraulic fracturing is essential for designing hydraulic fracture treatments. Multiple physical ... -
Numerical simulations of wellbore cement sheath microannuli leakage in Gulf of Mexico wells
(2021-02-25)The Gulf of Mexico (GoM) is home to more than 50,000 oil and gas wells with approximately 30,000 wells that are plugged and abandoned leading to concerns of oil and gas leakage where currently, little to no monitoring is ... -
