Abstract: Embodiments of proppants are described herein. In one embodiment, a proppant for hydraulic fracturing includes a proppant body. The proppant body has a length (L) and an outside diameter (D), and the proppant body length (L) to the proppant body outside diameter (D) ratio (L/D) is about 0.3 to about 5.0. The proppant body includes a space frame, and the space frame includes a plurality of rigid members creating a plurality of openings allowing fluid to flow through the proppant thereby increasing permeability. In another embodiment, a proppant for hydraulic fracturing includes a substantially cylindrical proppant body with a substantially circular cross-sectional area and an internal flow path with a substantially circular cross-sectional.

Abstract: The simultaneous control of the two forms of mercury in petroleum reservoirs (elemental and particulate HgS) is accomplished by the use of agents which react with the elemental mercury and bind the particulate HgS to the formation material: a mercury capture agent and a chemical sand control agent. The elemental control agent reacts with and adsorbs the elemental mercury. The chemical sand control agents reduce or eliminate the dislodging of fine particulate mercury from the surface of the formation material. This simultaneous control can be applied for a new well during well completion operations wherein analyses indicate the presence of mercury. This simultaneous control can also be applied to a currently producing well during a work-over when mercury is detected in the gas or crude products.
