摘要： The present invention describes a hydraulic cement composition, process and use thereof, wherein the composition comprises a hydraulic cement composition with increased resistance against carbon dioxide (CO2) for application in reservoirs such as oil and gas and carbon capture and storage (CCS) wells; with improved performance of cement paste formulations as a material for application in primary, secondary cementing, recovery and/or plugging operations, of reservoirs/wells that operate with high CO2 content; as a technological alternative to guarantee the integrity of wells in CO2-rich environments for long periods of time, without any additional intervention to the already current operational procedures for cementing wells, and with cost reduction in relation to class G cement (currently, the main raw material); and sufficient chemical resistance to carry out enhanced oil (EOR) and gas (EGR) recovery by injecting high levels of CO2, increasing reservoir pressure throughout the extraction period of hydrocarbon reservoirs.

摘要： Cement slurries, cured cements, and methods of making cured cement and methods of using cement slurries are provided. The cement slurries have, among other attributes, improved rheology, such as improved flowability and pumpability and may be used, for instance, in the oil and gas drilling industry. The cement slurry contains water, a cement precursor material and a surfactant having the formula R—(OC2H4)x—OH where R is a hydrocarbyl group comprising from 10 to 20 carbon atoms and x is an integer from 1 and 10. The cured cement have improved strength and density properties due to reduced fluid loss and even placement during curing. The cured cement contains a surfactant having the formula R—(OC2H4)x—OH where R is a hydrocarbyl group comprising from 10 to 20 carbon atoms and x is an integer from 1 and 10.

摘要： An hydraulically set oil-permeable cement body is provided in the form of a stand-alone block or briquette for preserving cooking oil during deep fat frying, said body. It has substantially no free water or having a low free water content for resisting damage on immersion in cooking oil and initial heating and is enclosed in packaging that resists ingress of water or water vapor The block or briquette consists of >50 wt % of a mixture of milled white OPC clinker and white OPC, optionally silica 1-2 wt % and/or titania (TiO2) 1-2 wt % and optionally further ingredients selected from calcium silicate, magnesium silicate, aluminum silicate, natural feldspars, natural sodium zeolites, natural calcium zeolites, synthetic sodium zeolites, synthetic calcium zeolites, wollastonite, calcium hydroxide, clays, pillared clays, activated clays/earths, talcs/kaolinite, amphiboles, granite porphyry, rhyolite, agalmatolite, porphyry, attapulgite and diatomaceous earth. It has the properties that calcium and magnesium substantially do not leach into the oil and that it is porous so that oil can diffuse into it and contaminants can be deposited on and within it.
