... Abstract This study investigated the influence of reservoir and geomechanical properties on CO 2 storage performance, focusing on trapping mechanisms, pressure evolution, displacement, and plume migration in saline aquifers of the Gulf Coast region. We conducted a numerical simulation...

... in mitigating casing deformation. Current operators redesigned a cementing material with high-strength beads which would collapse when stresses are above the designed threshold, which would "absorb" the formation displacement and reduce the severity of casing deformation caused by the aforementioned mechanisms...

... cases were studied. The new tool has two mechanisms to prevent gas phase from entering the tubing. The first mechanism is the breakage of the mixture’s wave by the bull plug of the tool. The second mechanism is the separation of small gas bubbles due to the flow through the tortuous path inside the tool...

... has risen as a number of successful pilots have been reported; however, little information is available on recovery mechanisms for the process. This paper evaluates oil swelling caused by diffusion and advection processes for gas injection in unconventional reservoirs. To accurately evaluate gas...

... strengthening " is conducted to increase the fracture gradient. The method relies on propping and/or sealing the fractures with specially designed materials. Different competing theories exist for wellbore strengthening mechanisms. These can be categorized into two groups. The first group believes...

...Introduction Abstract This paper presents a mathematical model and its numerical solution, describing mass-transfer between a gas flowing in a fracture and resident fluids in the adjacent matrix block. The model accounts for diffusion and convection mass-transfer mechanisms both for gas...

... As we are using hydraulic energy to operate the extendable arm drill bit, we need some kind of a plunger system to transform this hydraulic energy into mechanical energy. We use a dual plunger mechanism for this specific function. Dual because we intend to transform a small amount of hydraulic...

Work performed in Latin America recently showed the limitations of this process and how shallow liner-top installations might not have the string weight to apply a sufficient setting force to the liner-top packer...

... fed to the bacteria. Parameters relating to transport, growth, and metabolite production by microorganisms in petroleum reservoirs need vigorous research. Microbial transport studies must be performed under reservoir conditions. The following are the main types of chemicals and mechanisms...

The results of this study strongly indicate that the sand and shale laminations present in the Mesaverde reservoir act as a hydraulic fracture height containment mechanism. Two events are presented as the reasons...

... Abstract A large Illinois oil field implemented the use of a new low cost manual tubing rotator in 25 marginal oil wells to reduce wear failures. Wear failures were indicated by "tubing splits" (Mechanical Wear 1 ) or "corrosion occurring along a straight line due to corrosion inhibitor being...

This paper describes the state of the art of hydrate prevention, detailing hydrate structure, conditions and mechanisms of formation, and developing approaches – from the conventional to the cutting-edge – to hydrate inhibition. Its focus on low-dosage inhibitors, including a review of kinetic...

... Abstract Well stimulation normally consists of matrix acidizing, acid fracturing and proppant fracturing. The optimum stimulation treatment depends on both reservoir characteristics and the formation damage mechanism. The oil recovery can be improved with successful stimulation treatments...
