摘要： An apparatus is used on top of a column of drilling fluid in an annulus of a wellbore. The apparatus includes at least one floating device, at least one receiver, a communication interface coupled to the at least one receiver, a processor coupled to the at least one receiver and the communication interface, and a memory coupled to the processor. The memory includes instructions configured to perform a method that includes obtaining a start command to generate fluid level data, generating the fluid level data using the at least one floating device and the at least one receiver, and transmitting the fluid level data using the communication interface.

摘要： A system displacing cement in an annulus of a well is disclosed. The system includes a casing string with a casing outer circumferential surface, wherein the casing outer circumferential surface delineates a boundary of the annulus and a wiper plug, wherein the wiper plug is placed to follow the displacement of the cement in the annulus. Further, the system includes a float collar, having an outer circumferential surface delineated by the inner circumferential surface of the casing string, configured to allow the cement to pass downward with respect to a surface, and a displacement efficiency calibration collar, having an outer circumferential surface delineated by the inner circumferential surface of the casing string, configured to control volume of the cement displaced in the annulus, wherein the displacement efficiency calibration collar includes a calibration shearing disc.

摘要： A system includes a first tubular string within a wellbore and a collar coupled to a top of the first tubular string. The collar may include a body extending from a first end to a second end. The body includes an internal ring extending radially inward from an inner surface of the body. The internal ring includes at least two holes extending through a top surface of the internal ring to a bottom surface internal. Additionally, a second tubular string within the wellbore extends through the first tubular string. An outer ring of the second tubular string lands on the internal ring.

摘要： A conductor running and cementing bracket (CRCB) includes a plurality of support beams for supporting a conductor upon engagement with a conductor landing joint disposed on the conductor, wherein the plurality of support beams comprise a first set horizontally fixed to a second set. The CRCB further includes a side door elevator to grip the conductor thereby preventing further downhole movement at a landing level and a plurality of adjustable conductor extension sleeves arranged on the second set and extendable to variable lengths to accommodate conductors of varying diameters. The landing level of the conductor is below a rotary table level configured to hold a drill pipe via a rotary slip. Once the side door elevator is gripping the conductor, the conductor landing joint is removed and a drill pipe with a stinger is run into a wellbore. Upon running the drill pipe, a cementing operation is conducted.
