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 ... -
The accuracy of pulsed neutron capture logs for residual oil saturation determinations.
(1981)Pulsed neutron capture logs have been used to determine residual oil saturations for many years. A previous study found that at low values of residual oil saturation (ROS) conventional pulsed neutron logging techniques did ... -
Acoustic anisotropy measurements and calibration of the non-hydrostatic in-situ stresses in a wellbore.
(2007)The comparison of the static and dynamic stress-strain data (measured from borehole strain gages and velocities) indicates that velocities have to be calibrated according to the rock type to take into account the specific ... -
Analysis of pressure build-up in an infinite two-layered oil reservoir /
(The University of Oklahoma., 1975) -
Anisotropic effects upon amplitude-vs-offset response in realistic earth models.
(2000)The derivation and computation of the reflection coefficient for general anisotropic media is described along with software written to implement the computation. This program is then used to compare the reflection response ... -
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 ... -
Application of a New Yield Strength Acquisition Method to the Calculation of Collapse Pressure
(2018)The accuracy of a casing collapse prediction is critical to a successful casing design program. This is especially true today as the likelihood of HPHT reservoirs and difficult conditions downhole has become increasingly ... -
Application of PEBI grid simulation to analyze pressure-transient behavior of hydraulically fractured vertical wells.
(2002)Because of their flexibility while handling non-orthogonal systems, in this study, PEBI grids, implemented in a commercial simulator were employed to solve the mathematical models. However, it was first necessary to study ... -
Application of Tiab's Direct Synthesis technique to multi-layer naturally fractured reservoirs.
(2000)Next, the problem of the pressure behavior of a well crossed by a uniform-flux and infinite-conductivity vertical fracture and located in a single-layer and multilayered bounded square reservoir with a double porosity ... -
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 ... -
Bottom hole analyses of gas kick (inflow) and gas reservoir characterization while drilling underbalanced.
(2005)This study presents two new models developed to analyze gas flow between the reservoir and the wellbore while drilling underbalanced. Three drilling operational stages were considered in the analyses. These stages are the ... -
Case Study: Integrated Core Modeling and Simulation of Unconventional Hydraulically Fractured Wells in the Delaware Basin
(2020-07-30)The Early Paleozoic Wolfcamp formation is one of the main unconventional reservoirs in the Delaware Basin, and highly targeted by U.S. companies. Innovative completion techniques and representative core analysis have ... -
Chemical Flood Under High Total Dissolved Solids (TDS) Conditions
(2014-08-15)After the primary and secondary production, there is still a great potential of enhanced oil recovery (EOR). Currently, the high oil price, increase of oil demand and maturing oil fields and the improvement in surfactant ... -
Chemoporoelastic solution of transversely isotropic saturated porous media.
(2004)The solution is closed-form in the Laplace domain; and is then inverted to the time domain by using Stehfest's (1970) algorithm. This solution simulates the chemoporoelastic process triggered by drilling a borehole in ... -
Comparative Study of Pore Structure Characterization for Different Rock Samples Using Digital Images
(2019-12)Due to the scarcity in supply of energy and slumping production from conventional reservoirs, exportation from unconventional tight shale reservoirs has received considerable scholarly attention in recent years. However, ... -
A Comparison Of Coherence Enhancement, Probabilistic Neural Network, And Convolutional Neural Network Fault Imaging With Manual Interpretation In The Taranaki Basin Area, New Zealand.
(2021-05-17)Fault identification is a key aspect in seismic interpretation, and model generation is an essential task to achieve any accurate, precise reservoir modeling or structural framework that solves problems in the subsurface. ... -
Compositional flow in porous media :
(1976) -
A coupled model for the prediction of fluid and reservoir properties from minifrac tests.
(1999)A computer program was developed for the calculation of all parameters mentioned above and also to automatically curve-fit the main output and diagnostic plots of the model.
