... drilling for hydrocarbon. Shale is a fine-grained, sedimentary rock with distinct layered characteristics. Shale formations are highly compacted, partially dehydrated, and carry significant amounts of clay minerals 1 . The use of improper fluid in drilling shale formations could result in several drilling...

... Abstract There are abundant clay occurrences in the oil sand reservoirs in the Clearwater Formation at Cold Lake. It has been suggested that hydrothermal reactions of the clay minerals may cause permeability damage during thermal recovery. To quantify such the damage, two corefloods (BCF1 and...

... Abstract Samples of terrigenous rocks from producing Devonian reservoirs were investigated by us by physical and chemical methods. It was shown that content of held organic substance decreased with increase of clay minerals content in rock sample. Organic substance from clay containing rocks...

... Abstract Clay minerals in hydrocarbon reservoirs often cause formation damage. The wellknown examples are fines migration, clay swelling, and hydrothermal mineralreactions. In the last few decades, numerous clay stabilizers have beendeveloped to control formation damage related to clay...

...., in water- or gas-flooding situations, zones containing active bottom water or gas caps) or nor economical (e.g., in some horizontal wells). Another approach is to stimulate the near-wellbore region using acids, which dissolve either the clay minerals themselves (HF acid) or the surrounding formation...

... forrecrystallization can be identified: Ostwald ripening, formation of new mineralphases of greater thermodynamic stability and changes in the chemicalenvironment, such as pH, resulting from the hot-water process. The transformations of one clay mineral to another in response to changingenvironments have been known...
