.... While the severity of the skin may vary from well to well the mechanisms of damage are generally mechanical, chemical, biological, or thermal in nature. Whereas a formation with no damage would have a skin factor of zero a well with serious damage may have a skin factor of 20 or greater. Formation...

... Abstract Glass reinforced epoxy (GRE) lining is a polymer composite material, the main components of which are a thermosetting resin and a fiberglass reinforcement. The combined properties of its components result in a material with excellent chemical, thermal and mechanical performance. GRE...

... interpretation. From the formation damage study, biopolymer was highlighted as a limiting damage mechanism. This prompted both Equinor and Schlumberger to look at alternative ways to provide rheological support without using biopolymers. A mono-valent biopolymer free reservoir drill-in fluid was designed...

..., and this has been widely concerned. In this paper, we firstly reviewed and summarized the main damage mechanisms during the hydraulic fracturing of tight and shale reservoirs, including formation damage induced by fluids invasion, rock-fluids and fluids-fluids incompatibilities, proppants compaction...

... fluid used to treat formation damage depends on the formation and the damage mechanism. It matters when we start looking at fluid volumes and placement techniques. For vertical wells, treatment volumes typically range from 50 to 150 gallons of acid per foot of perforations. For instance, a 10 foot...

... ) Most studies until recently have been investigating the surface attachment of surfactants and crude oils separately, however Xiang, et al, investigated the detachment of adsorbed bitumen and the impact of initial surface wettability. The investigators proposed a number of mechanisms for bitumen...

... and lowered conductivity damage to plugging. Controlled release of the chemical from the ISP like substrate allows only a certain amount of chemical needed for inhibitor control, preserving the rest of the inhibitor for subsequent release. The incorporation of a delay mechanism in the slow release asphaltene...

... flowback aids, it is unable to resolve the mechanisms associated with porescale transport. The goal of this study is to directly visualize and quantify the pore-scale dynamics of fracturing fluid injection and oil flowback using a microfluidic chip device and correlate these observations to the coreflood...

... Abstract Adequate well injectivity is required to successfully inject large volumes of CO 2 through a minimum number of wells. Brine vaporization in the wellbore vicinity has been identified as a major CO 2 injectivity impairment mechanism especially in deep saline reservoirs. A bundle...

... from the crude oil, due to various mechanisms (e.g., changes in phase equilibrium and composition). Typical treatments for these deposits include solvents and acids. More recently, microemulsion fluids have been used for production enhancement. The objective of this work is to formulate...

... the wellbore. While this damaged or"crushed" zone has been a subject of numerous studies involving sandstones, the specific mechanisms of perforation damage in carbonates and theeffect on flow efficiency are not well understood. We examine the carbonate crushed zone at a fundamental level by interpreting...

The first model takes a pore-scale approach that models straining of larger particles through the pore structures extracted from X-ray tomographic images of rock and grain pack samples from...

... Abstract Tight gas condensate reservoirs are an important source of reserves and exhibit unique flow and thermodynamic behaviors. Owing to the overwhelming effects from nano-pores, formation damage mechanisms are uncertain. Significant phase and compositional change occurs in the circumstances...

... Alteration of pore structure occurs as a result of adverse formation damage processes such as formation fine migration, filtrate invasion, rock compaction and deformation, acid stimulation and other mechanical processes which lead to formation permeability impairment. The parameter to estimate...
