A Heuristic Simulation and Optimization Algorithm for Large Scale Natural Gas Storage Valuation under Uncertainty
(2015-04-23)
Natural gas storage valuation is an optimal scheduling of natural gas storage facilities. It is a complex predictive decision making research problem since it involves the financial decisions and the physical storage ...
Laboratory imaging of hydraulic fractures using microseismicity.
(2002)
Developing robust algorithms and software for locating the coordinates of hydraulic fracturing-induced microseismic events, and for simulating the first motion of the induced waveforms were central tasks for this research. ...
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 ...
Inferring Interwell Connectivity by Statistical Diagnostic Tools and Signal Processing Methods
(2018-12-14)
Data mining has become increasingly crucial in deciphering reservoir dynamics. Operators currently acquire an enormous amount of data that are not effectively being used. These data contain valuable information about ...
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 ...
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 ...
Importance of Capillary Heterogeneity in Developing a Representative Reservoir Model for Shales with Complex Fractures
(2016-12-16)
Our advancement in hydraulic fracturing has enabled us to produce shale formations economically. The formation stimulation is successful when the effective transport properties of the formation is improved significantly, ...
A DISLOCATION-BASED BOUNDARY ELEMENT METHOD TO MODEL PRESSURIZED FRACTURES
(2019)
A significant portion of hydrocarbon and geothermal resources in the world, and especially in the United States, is unconventional. Some of the unconventional resources have special geological structures so that their ...
EXPERIMENTAL INVESTIGATION OF THE EFFECTS OF ROTATIONAL SPEED AND WEIGHT ON BIT ON DRILLSTRING VIBRATIONS, TORQUE AND RATE OF PENETRATION
(2017-05-12)
Experimental investigation was carried out on an automated drilling rig fabricated for the Drillbotics competition. The effects of rotational speed and weight on bit were observed on drillstring vibrations, torque and rate ...
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 ...
