Studying “fitness for service” of the sealing assemblies and cement system
(2018-05)
Well integrity is a crucial phase of well design and construction, as such multiple barriers are usually installed in wells to prevent any migration of formation fluids. One of these barriers include the elastomeric sealing ...
EXPERIMENTAL CHARACTERIZATION OF BRINE IN CRUDE OIL EMULSIONS AND ITS PERFORMANCE IN ARTIFICIAL LIFT SYSTEMS
(2018)
Understanding the behavior of water in oil emulsions can prevent flow assurance problems and the conditions at which these two fluids can mix. The stability and rheology of water in crude oil emulsions was studied for three ...
EXPERIMENTAL INVESTIGATION OF PROPPED FRACTURE CONDUCTIVITY
(2018-05)
Hydraulic fractures act as conduits connecting a wellbore to nanodarcy permeability unconventional reservoirs. Proppants are responsible for enhancing the fracture conductivity and help in maintaining high production rates. ...
NUMERICAL SIMULATION OF THE EFFECTS OF RESERVOIR HETEROGENEITY, FRACTURES, AND MULTI-WELL INTERFERENCE ON PRESSURE TRANSIENT RESPONSES USING MULTISTENCILS FAST MARCHING METHOD
(2017-08-28)
Analysis of rate and pressure transient responses of a well in spatially heterogeneous reservoir cannot be performed using conventional well-test analytical equations. An accurate analysis of transient pressure/rate responses ...
DENSITY CHANGES AND COMPOSITIONAL PATH DURING CO2 INJECTION
(2016-12-16)
CO2 EOR has been used for a couple of decades as it improves oil recovery. With more than 50% of original oil in place (OOIP) remaining inside reservoir after primary and secondary stage, more and more companies start to ...
TRANSIENT TEMPERATURE BEHAVIOR IN WELLBORE AND SURROUNDING FORMATION
(2017-05-12)
Transient temperature behavior in a wellbore develops as a result of heat exchange between fluid in the wellbore and surrounding formation as the hot fluid from reservoir moves upward in production, or vice versa during ...
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 ...
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 ...
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 ...
