摘要： A drilling fluid comprises an aqueous solution; a clay-based component comprising layered silicate; and a viscosifier additive comprising poly(acrylamide-co-diallyldimethylammonium chloride) (poly(AAm-co-DMAC)) polymer. The polymer comprises a number average molecular weight of from 10,000 g/mol to 2,000,000 g/mol. The layered silicate and poly(AAm-co-DMAC) reacts to form a silicate-poly(AAm-co-DMAC) complex within the aqueous solution. A mass ratio of the poly(AAm-co-DMAC) to the layered silicate is 1 to 8.

摘要： A method of drilling a subterranean geological formation is described. The method includes driving a drill bit to form a wellbore into the subterranean geological formation thereby producing a formation fluid including hydrogen sulfide (H2S). The method includes injecting a drilling fluid into the subterranean geological formation through the wellbore. The drilling fluid composition includes 0.25 to 2 wt. % of a primary H2S scavenger which is potassium permanganate. The drilling fluid composition includes an invert emulsion which includes a continuous phase including mineral oil and a dispersive phase including water. The potassium permanganate present in the drilling fluid composition reacts with the H2S present in the formation fluid to produce a dispersion of manganese-containing particles which are at least one selected from the group consisting of manganese sulfide and manganese sulfate.

摘要： A drilling fluid formulation is provided, which includes an aqueous base fluid, a synthetic modified phyllosilicate as an anti-sagging additive, an inorganic base, and a weighting agent (e.g. barite). The synthetic modified phyllosilicate contains a clay material (e.g. smectite) and a metal selected from ruthenium, rhodium, palladium, osmium, iridium, and platinum. The synthetic modified phyllosilicate is effective in preventing barite sagging as demonstrated by low sag factor when drilling at elevated temperatures. Rheology properties of the drilling fluid including gel strength, yield point, plastic viscosity, and storage modulus are also specified.
