Experimental Investigation of Molecular Hydrogen Effect on Cement Related to Well Integrity for Underground Hydrogen Storage
(2022)Underground Hydrogen Storage (UHS) in the subsurface is an alternative to overcome limitations associated with a fluctuating production of renewable energy sources. The excess energy produced can be converted to hydrogen ... -
Experimental investigation of polymer-based lost circulation materials for fluid loss treatment under high temperature using additive manufacturing
(2023-05-13)Lost circulation continues to be one of the most troublesome problems encountered during drilling. The financial cost of lost circulation in geothermal drilling can rise to 15% of the total drilling cost. A corrective ... -
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. ... -
EXPERIMENTAL INVESTIGATION OF SHALE-DRILLING FLUID INTERACTION AND ITS IMPLICATIONS ON DRILLING EFFICIENCY
(2020-05-08)The United States (US) energy consumption is growing at an amazing rate. The high demand in oil and gas has created a surge in shale exploration, drilling, and production. Shale formations have become a source of attraction ... -
Experimental Investigation of Synthetic and Microbial Surfactants for Enhanced Oil Recovery in Bone Spring Sandstones
(2022-12-17)Surfactants have been used to increase hydrocarbon recovery to meet the increasing demand for oil and gas. This mechanism of using surfactants reduces the Interfacial Tension (IFT) at the fluid/fluid interface and wettability ... -
EXPERIMENTAL INVESTIGATION OF THE CEMENT BOND INTEGRITY BY APPLICATION OF DIGITAL IMAGE CORRELATION (DIC) TECHNIQUE
(2019-05)API Class G and H Portland cements are the most recommended cements for different well operations in order to have good well integrity throughout the life of the well. A loss of zonal isolation is a result of improper ... -
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 ... -
AN EXPERIMENTAL INVESTIGATION ON CREEP BEHAVIOR OF SHALE ROCKS: WITH EMPHASIS ON THE INFLUENCE OF TEMPERATURE AND ANISOTROPY
(2017-05-12)The deformation of materials under constant load over time is called creep. The conductivity of fracture produced by hydraulic fracturing decreased over time as a result of this time dependent phenomenon that requires to ... -
Experimental investigations of the effect of oil based mud (OBM) contamination on long-term integrity of API cements
(2020-12)Well construction, well abandonment, and restoration of well integrity are the reasons at a broad level why cementing jobs are performed. During the well construction phase, the primary objective of the cementing job is ... -
Experimental Modeling of Geometry and Evolution of Structures above Ductile and Frictional Detachments
(2016-05-13)Fold-thrust belts formed above ductile units like salt are typically characterized by detachment folds, whereas those formed above frictional detachments contain fault-related folds, such as fault-bend folds and duplexes. ... -
An Experimental Setup to Measure Argon Leak Rate Through Barriers for Static and Rotational Motion
(2022-08)As a greenhouse gas, methane significantly impacts global warming and air pollution. Oil and gas production, crude oil transportation, refining, and natural gas processing, transportation, and distribution are considered ... -
Experimental study of asphaltene accumulation in a sandstone core plug
(2021-08)Hydrocarbon production leads to the disturbance of several thermodynamic equilibriums including the destabilization of crude oil. Asphaltenes precipitation, aggregation and deposition inside the hydrocarbon reservoirs ... -
EXPERIMENTAL STUDY OF EFFECT OF PROPPANT CONCENTRATION, TYPES, SIZES, ROCK MINERALOGY AND OVERBURDEN STRESS ON FRACTURE CONDUCTIVITY
(2019-12-13)Hydrocarbon production from unconventional reservoirs, particularly shales, requires massive hydraulic fractures to expose the large surface areas within the formation and provide a conduit to the wellbore. Proppants are ... -
EXPERIMENTAL STUDY OF FLOW AND RHEOLOGY OF WATER-IN-CRUDE OIL EMULSIONS
(2019-05-10)The formation of water-in-crude oil emulsion is one of the main causes of flow assurance issues in petroleum production systems. These mixture exhibit changes in their flow behavior, and the rheological models used to ... -
EXPERIMENTAL STUDY OF GAS INJECTION ENHANCED OIL RECOVERY IN SHALE RESERVOIRS
(2019)Miscible gas injection enhanced oil recovery (huff-n-puff gas injection) has received increased attention especially in the unconventional plays like the Eagle Ford, where oil recovery is as low as 5 – 10% (Sheng, ... -
