Enabling CO2 sequestration using Proppants Optimised for Pure Propane Stimulation: ECO PrOPPS

“使用专为纯丙烷刺激而优化的支撑剂实现二氧化碳封存”项目ECO-Propps将基于现有的专利支撑剂技术(在IUK项目“Glass Propps”下开发)来开发功能性玻璃支撑剂，这些支撑剂可以按需“激活”，以在使用寿命结束时密封页岩气井，从而使该井能够用作储存大量二氧化碳气体(潜在地高达所提取甲烷燃烧产生的二氧化碳的三倍)。这种玻璃支撑剂的设计将与“纯丙烷刺激”(PPS)兼容，与传统的水基水力压裂相比有许多好处，其中之一是减少了对页岩的损害，从而最大限度地增加了吸收二氧化碳的潜力。如果成功，这项技术可能会使“碳负”能源工厂成为可能。

The ‘Enabling CO2 sequestration using Proppants Optimised for Pure Propane Stimulation’ project, ECO-PrOPPS, will build upon existing patented proppant technology (developed under IUK project ‘Glass PrOPPS’) todevelop functional glass proppants which can be ‘activated’ on-demand to seal up a shale gas well at the end oflife, as such enabling the well to be used as a store for significant volumes of CO2 gas (potentially up to threetimes the CO2 generated by combustion of the methane extracted). The glass proppant will be designed to becompatible with ‘pure propane stimulation’ (PPS), offering many benefits over conventional water-basedfracking, one of which is the reduced damage to the shale rock thus maximising the potential for CO2absorption. If successful this technology could enable ‘carbon-negative’ energy plants.
