Abstract
Official abstract text for this publication.
A proppant for use in hydraulic fracturing in a subterranean formation to prop a fracture therein includes a material which is adapted to sequester at least one target species formed external to the subterranean formation and formed external to the proppant and the material.
First claim
Opening claim text (preview).
What is claimed is: 1. A proppant for use in hydraulic fracturing in a subterranean formation to prop a fracture therein, comprising: a material to permanently sequester within the proppant at least one target species which is a fluid and which is formed external to the subterranean formation and formed external to the proppant and the material via interaction with the at least one target species. 2. The proppant of claim 1 wherein the at least one target species is an acid gas. 3. The proppant of claim 1 wherein the at least one target species is carbon dioxide. 4. The proppant of claim 1 wherein the material is selected from the group consisting of sodium bicarbonates, calcium bicarbonates, olivine, dunite, pyroxene, magnesium silicate, ankerite, dawsonite, serpentine, calcium oxides, magnesium oxides, magnesite, siderite, and dolomite. 5. The proppant of claim 3 wherein the material is selected from the group consisting of sodium bicarbonates, calcium bicarbonates, olivine, dunite, pyroxene, magnesium silicate, ankerite, dawsonite, serpentine, calcium oxides, magnesium oxides, magnesite, siderite, and dolomite. 6. The proppant of claim 5 wherein the material comprises at least 55% by weight of the proppant. 7. The proppant of claim 4 further comprising a bulk proppant core and a layer outside the bulk proppant core comprising the material adapted to sequester the at least one target species. 8. The proppant of claim 7 wherein the bulk proppant core provides exhibits bulk material properties suitable for well completion. 9. The proppant of claim 7 wherein the bulk proppant core comprises a silica sand, a sintered material or a ceramic material. 10. The proppant of claim 7 further comprising a completions layer outside the layer comprising the material adapted to sequester the at least one target species, the completions layer providing protection to the layer comprising the material adapted to sequester the at least one target species during completions processes. 11. The proppant of claim 10 wherein the completions layer provides chemical isolation of the material at least for a period of time. 12. The proppant of claim 10 wherein the completions layer comprises a polymeric material. 13. The proppant of claim 10 wherein the at least one target species is transportable through the completions layer which is permeable to the at least one target species. 14. The proppant of claim 10 wherein the completions layer is removable. 15. The proppant of claim 1 further comprising the at least one target species adsorbed upon the material.
