IMPROVING THE EnKF FOR HISTORY MATCHING: MULTISCALE PARAMETERIZATION AND BOOTSTRAP-BASED SCREENING
(2010)
Although the ensemble Kalman filter (EnKF) has been remarkably successful for history matching and quantifying uncertainty in petroleum reservoirs, there have been problems with the use of small ensembles, and occasionally ...
PRODUCTION OF HYDROCARBONS FROM ORGANIC NANOPORES: A COMPREHENSIVE STUDY USING MOLECULAR SIMULATIONS
(2020-07)
Molecular models of organic pores are created using molecular dynamics simulations to investigate fluid behavior of confined reservoir fluids and fluid transport through nanoporous shales, aiming to reveal the underlying ...
CORROSION BEHAVIOR OF TUBULARS IN SOUR GAS ENVIRONMENT
(2017)
The existence of corrosive gases (CO2 and H2S) in oil wells under High-Pressure High-Temperature (HPHT) condition exacerbates the severity of tubular corrosion and increases the need for different corrosion mitigation ...
Production performance of horizontal wells in gas-condensate reservoirs.
(2002)
Gas condensate reservoirs go under two kinds of changes in their lifetime. The phase change and the physical properties change. Both the changes have been handled in this study using the pseudopressure function integral ...
Long term experimental investigation for leakage and permeability of the cement-casing microannulus
(2021-05-14)
The oil and gas industry is the primary provider of energy globally. Energy extraction from wells takes place through several stages, such as exploration, drilling and production, and then plugging and abandonment. The ...
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 ...
Finite element analysis of the heat and mass transfer in a magma body.
(1981)
The conductive moving boundary model developed in this study indicates that the solidification of magma takes more time when the latent heat of fusion is considered. The convective moving boundary model shows that the ...
Experimental and advanced computational modelling study of downhole elastomer seal assemblies
(2020-05)
Elastomers seals are widely used in various drilling, completion, and production equipment. One such equipment is liner hanger which has become integral part of modern well designs. Failure of liner hanger seal assembly ...
Development of suitable approximation algorithms to be used in the description of heterogeneous reservoirs for secondary recovery studies.
(1981)
The prediction method makes use of flow capacity distributions in a heterogeneous reservoir.
Development of polymer gel systems for lost circulation treatment and wellbore strengthening
(2021-05-07)
Lost circulation is a frequent problem and a significant contributor to the non-productive time (NPT) in the drilling operation. Field reports and experimental studies have revealed that conventional solutions are doomed ...
