摘要： A buoyancy assist tool has an outer case with a rupture disk assembly connected therein. The buoyancy assist tool defines the upper end of a buoyancy chamber in a well casing. A sleeve in the outer case traps the rupture disk membrane after it has ruptured to provide full bore flow through the casing.

摘要： A buoyancy assist tool has an outer case and a rupture disk connected in the outer case. A sleeve is disposed in the outer case and movable from first to second position in the outer case. A rupture disk membrane of a rupture disk prevents the sleeve from moving to the second position prior to the rupture disk membrane rupturing. The outer case is configured to be connected in a well casing. A lock ring holds the sleeve in the first position.

摘要： A packer assembly and valve assembly without special or custom threads are used to provide a threadless float assembly. A packer assembly with inserts disposed in slip wedges is set by applying compressive forces using a setting tool. A valve assembly may be positioned during setting of the packer assembly between a holder and a setting tool insert end or may be positioned abutting a spacer after setting of the packer assembly. A setting tool and a plunger along with a pump are used to apply compressive forces on the packer assembly to set the packer assembly without requiring that the packer assembly or the valve assembly have special threading as the inserts, holder and spacer maintain the components in a stationary position.

摘要： A downhole apparatus comprises a casing string with a frangible disk positioned therein. A flow barrier is connected in the casing string and spaced downwardly from the frangible disk. The frangible disk and the flow barrier define a buoyancy chamber. The sliding sleeve will impact and shatter the frangible disk into a plurality of pieces that will pass downwardly in the casing after the casing has been lowered to a desired depth.

摘要： A buoyancy assist tool has an outer case and a sleeve disposed in the outer case. The sleeve is movable from first to second positions in the outer case. A permeable membrane is attached to the movable sleeve at a lower end thereof. A rupture disk is mounted in the outer case. Fluid flow through the permeable membrane detaches the sleeve from the outer case and moves the sleeve from the first to the second position. In the second position, the sleeve creates an open bore for the passage of downhole tools therethrough.

摘要： An instrumented wiper dart configurable at the wellsite comprising any combination of a sealing member, a sensor sub, an electronics package, and a communication system; wherein the sealing member is cylindrical in shape, releasably coupled to the wiper assembly, and configured to sealingly engage the inner surface of a workstring. The sensor sub is release releasably coupled to the wiper assembly, and includes one or more sensors to measure a property of the wellbore environment. The electronics package is releasably coupled to the wiper assembly, configured to receive one or more data sets from the sensor sub, and transmit one or more data sets to the communication sub. The communication sub is configured to transmit the one or more data sets; and wherein the instrumented wiper plug is displaced down the workstring in response to a volume of fluid pumped from surface.
