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 ...
A LOW-FREQUENCY ASYMPTOTIC FORMULATION TO ESTIMATE HYDRAULIC FRACTURE PROPERTIES FROM PRESSURE DATA
(2016-12-16)
The key drivers of success in unconventional oil and gas recovery, specifically in shale plays, is the rapid growth in hydraulic fracturing and horizontal well technology. With these completion methods, wells contact ...
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 ...
INVESTIGATING MICROSTRUCTURAL HETEROGENEITY IN ORGANIC SHALE VIA LARGE-SCALE, HIGH RESOLUTION SEM IMAGING
(2017)
The physical properties of shale are fundamentally controlled by its microstructure; however, shale is problematic due to microstructural heterogeneity that can exist across multiple scales. This creates difficulty in ...
PROPPANT FLOW AND TRANSPORT MODELING IN DEFORMABLE HYDRAULIC FRACTURE NETWORKS
(2018)
The objective of the hydraulic fracturing stimulation is to create a large volume of fractured rock with enhanced permeability. The effectiveness of a hydraulic fracturing stimulation depends on maintaining the created ...
HUMAN-CENTERED OPTIMIZATION OF WELL CONTROL: IMPLICATIONS FOR DRILLING SAFETY
(2019-08-01)
Today 70% of incidents in offshore and marine environment are due to human factors (HF). Among all such incidents, loss of well control can have tremendous damage to human life, well, rig, underground reserves and to the ...
PERFORMANCE PREDICTION FOR DEEPWATER GULF OF MEXICO USING DATA MINING
(2016-08-05)
The estimation of recovery factor is important in every stage of hydrocarbon development, and multiple traditional techniques are available for engineering application for particular fields. However, the estimated recovery ...
Evaluation of multistage triaxial testing on Berea sandstone
(2004)
Conventional methods for obtaining failure envelopes require testing multiple samples, a luxury not enjoyed when dealing with core recovered from boreholes. Consequently, a multistage test performed on a single plug is ...
USING DATA ANALYTICS ON DIMENSIONLESS NUMBERS TO PREDICT THE ULTIMATE RECOVERY FACTORS FOR DIFFERENT DRIVE MECHANISMS OF GULF OF MEXICO OIL FIELDS
(2017-05-12)
The ultimate recovery factor is strongly affected by petrophysical parameters, engineering data, structures, and drive mechanisms. The knowledge of the recovery factor is needed for multiple decision makings and it should ...
DEVELOPMENT OF UNCONVENTIONAL RESERVOIRS: FLUID CHARACTERIZATION, STIMULATED RESERVOIR VOLUME DETERMINATION, AND PRODUCTION FORECASTING IN THE STACK
(2018-05)
The Mississippian-age Meramec Series is one of the primary producing intervals of the Sooner Trend in the Anadarko Basin of Canadian and Kingfisher (STACK) counties, Oklahoma and is currently among the most sought-after ...
