Abstract: A stage cementing tool for a wellbore comprises a tool body defining a flow port in a wall thereof. The tool body and wellbore define an annulus therebetween. A setting sleeve compresses a packer element as it moves from the first to the second position. The packer element expands radially outwardly to engage the wellbore as a result of the compression applied by the setting sleeve. A pump-out plug in the tool body is expellable into the annulus upon the application of pressure in the tool body after the packer element engages the wellbore.

Abstract: A method of producing a material. The material is produced by the steps of: providing a geopolymer mixture or solution comprising an aluminosilicate and an alkali material; allowing the geopolymer mixture or solution to partially set to form an at least partially set geopolymer including pore spaces; and exposing the at least partially set geopolymer to a metal silicate solution or mixture containing a metal silicate to allow the metal silicate to enter the pore spaces and react to form additional material within the pore spaces. The material may be used in well-cementing and as an abandonment plug.

Abstract: A method may include obtaining, by a computer processor, a request to initiate a cementing procedure. The method may further include determining, by the computer processor, an automated sequence for the cementing procedure. The method may further include transmitting, by the computer processor and based on the automated sequence, a cementing management command that triggers the cementing procedure for cementing equipment in a cementing system. The method may further include obtaining, by the computer processor, sensor data regarding the cementing equipment. The method may further include determining, by the computer processor and in response to the sensor data, whether to perform a next procedure in the automated sequence.

Abstract: A rupture apparatus (50) often deployed within a wall of a casing string (53) of an oil and gas well, comprising a housing (51) defining a housing bore (54) with a bore inlet and a bore outlet; a carriage carrying a rupturable component (12) the carriage being moveable in the housing bore between a rupturable position, an open and a closed position. Thus the bore can be opened or closed or closed subject to rupture of the rupturable component (12). Moreover, after rupture the bore can still be closed. Wireless signals are normally used to for control, especially electromagnetic or acoustic signals. A pressure balancing port (6) may be defined in a wall of the housing allowing fluid communication between at least a portion of the housing bore, and an outside of the housing which can pressure-balance the carriage such that it remains stationary unless actuated.

Abstract: A wellbore assembly to plug and abandon a wellbore below a setting depth includes a whipstock assembly configured to drill a lateral wellbore from a primary wellbore formed in a subterranean zone. The wellbore assembly includes a tool assembly connected to the whipstock assembly. The tool assembly is configured to be lowered into the primary wellbore during the same trip as the whipstock assembly. The tool assembly is configured to perform wellbore operations downhole of a casing window from which the whipstock assembly is configured to drill the lateral wellbore before the whipstock assembly drills the lateral wellbore.

Abstract: A method of cementing a wellbore includes injecting into the wellbore a non-aqueous fluid; injecting into the wellbore a cement slurry and a non-ionic surfactant composition after injecting the non-aqueous fluid; and allowing the cement slurry to set, wherein the non-ionic surfactant composition comprises an alkyl end-capped ethoxylated fatty alcohol, a chain extended non-ionic surfactant, or a combination comprising at least one of the foregoing.

Abstract: A wellbore isolation assembly includes an outer component and an inner component. The outer component is disposed at a first location in a wellbore. The inner component is disposed at a second location in the wellbore. The inner component is moved from the second location into engagement with the outer component at the first location to form a barrier within the wellbore. When deployed in the wellbore, the barrier inhibits passage of fluids. The wellbore isolation assembly is then retrieved from the wellbore.

Abstract: A method of producing a nanosilica-containing cement formulation, the method comprising the steps of mixing an amount of a determinant nanosilica particle and a functional coating; applying a dynamic initiator to trigger a reversible reaction of the functional coating to produce a reversible cage, where the reversible cage surrounds the determinant nanosilica particle to produce an encapsulated nanosilica; and mixing the encapsulated nanosilica and a cement formulation to produce the nanosilica-containing cement formulation.
