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 INVESTIGATION, CORRELATION, AND DIMENSIONAL ANALYSIS OF NEAR-WELLBORE FORMATION TREATMENT BY GEL PARTICLES AND PARTICLE-GEL SYSTEM
(2014-12)
Reservoir permeability heterogeneity with high permeability zones can create many problems in petroleum reservoirs such as lost circulation of drilling fluids and high water production in hydrocarbon producing wells. These ...
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 ...
Three-Dimensional FEM Modeling of Geothermal Reservoir Stimulation Using Stochastic Fracture Networks and Continuum Damage Mechanics
(2014-08)
Unconventional reservoirs are gaining more and more attention in recently years. Pore pressure and temperature variations in unconventional reservoirs during stimulation are of great importance in reservoir exploration and ...
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 ...
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 ...
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 ...
