Experimental and numerical simulation study of microbial enhanced oil recovery using bio-surfactants.
(2005)
A 2-phase, 10-component microbial enhanced oil recovery numerical simulator was modified to include reservoir salinity and facilitate surfactant and polymer injection. The effects of reservoir brine salinity and divalent ...
Simulation of asphaltene deposition in petroleum reservoirs during primary oil recovery.
(2000)
In this study, a polymer solution model for asphaltene precipitation was used to simulate the experimental data of asphaltene precipitation due to pressure depletion. The results predicted by the polymer solution model ...
Horizontal well productivity and wellbore pressure behavior incorporating wellbore hydraulics.
(2001)
This research reviews the equations used to determine horizontal well productivity, the models used for wellbore pressure, and develops a new method to estimate horizontal well productivity incorporating the effects of ...
Bacillus lipopeptide biosurfactants: Purification, structure-activity relationship, and in-situ production in oil reservoirs.
(2006)
Alternatively, biosurfactant activity can be manipulated by formulation of biosurfactant mixtures with different properties. The efficacy of biosurfactants from individual strains, and mixtures of biosurfactants from ...
3-D numerical simulation of horizontal well gravel pack.
(2004)
The modeling equations consist of five partial differential equations with five dependent variables, all of which were solved simultaneously. The system of partial differential equations was approximated using the ...
Anisotropic poromechanics of the wellbore coupled with thermal and chemical gradients.
(2002)
A generalized anisotropic porothermoelastic formulation incorporating fully coupled thermo-hydro-mechanical response of saturated porous media is developed. Governing equations are tailored for transversely isotropic media ...
Theoretical and experimental studies of power-law fluid flow in coiled tubing.
(2006)
Abstract not available.
The poromechanics of naturally fractured rock formations: A finite element approach.
(2003)
The mathematical models have been cast into finite element form and verified against analytical solutions for one-dimensional consolidation and an inclined wellbore in a fully saturated single-porosity formation subjected ...
