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, ...
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 ...
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 ...
Modeling Multicomponent Gas Flow in Liquids Rich Shales
(2016-05)
Production data acquired from liquids-rich shale reservoirs show a few very interesting trends:
1. A relatively constant gas-oil ratio (GOR) or condensate-gas ratio (CGR) although flowing bottomhole pressures may be below ...
EXPERIMENTAL STUDY OF PROPPANT TRANSPORT IN HORIZONTAL AND DIRECTIONAL WELLS
(2016)
Wellbore cleanouts represent the main application of the coiled tubing (CT) industry. A typical cleanout operation designed to remove solids from the wellbore using stationary circulation method involves tripping the CT ...
History matching production data using the ensemble Kalman filter.
(2006)
In this dissertation, the ensemble Kalman filter (EnKF) is refined for applications to the problem of history matching. This method assimilates data sequentially whenever data are acquired. It is a Monte Carlo approach, ...
