摘要: A valve assembly (1) for use particularly in a deviated wellbore of an oil, gas or water well comprises a body (50) with an axis and first and second resiliently deformable seats (20, 25) to seat a valve closure member (10a) such as a ball, the seats being deformable to allow passage of the ball at different first and second fluid pressures acting on the seated valve closure member. The first and second seats are axially spaced from one another on a control sleeve (60) on opposite sides of an inner end of a selectively operable fluid outlet conduit connecting the bore with an external surface of the valve assembly, and operation of the valve assembly at pressures between the first and second pressures opens and closes the outlet while maintaining the ball between the first and second seats.

摘要: Oil-based drilling fluid compositions comprising an oil phase comprising a base oil, an aqueous phase comprising water, at least one emulsifier, and one or more additives. The at least one emulsifier comprises an amino amide comprising the formula R—CO—NH—R′—NH2, where R is a fatty acid alkyl and R′ is an alkyl group. The one or more additives are chosen from a wetting agent, a rheology modifier, a fluid-loss control additive, and a weighting additive. Methods of making the oil-based drilling fluid compositions and methods of drilling a subterranean well utilizing the oil-based drilling fluid compositions are also provided.

摘要: A valve assembly for use in a wellbore of an oil, gas or water well, having a valve seat to seat a valve closure member such as a ball, and a control member that is adapted to cycle the valve assembly between first and second configurations of the valve assembly when the ball is seated on the seat. The valve assembly may be adapted to return the valve assembly to the first configuration when the valve closure member is seated on the seat, and may repeatedly, continuously and/or sequentially cycle from first to second configurations and back to first configuration to open and close an outlet port while the same valve member is seated on the seat. The valve seat may comprise first and second seat members and retain the ball in a cleft between the first and second seat members.
