Abstract: A method includes creating a chamber within an annulus between a wellbore casing and a drillpipe. An upper boundary of the chamber includes a seal and a lower boundary of the chamber includes a liquid surface and determining a volume of the chamber at a first time. The method further includes determining the volume of the chamber includes measuring, using a pressure gauge, a first pressure within the chamber, changing an amount of a gas in the chamber, and measuring, using the pressure gauge, a second pressure within the chamber. The method further includes determining a first volume of gas within the chamber based on the first and second pressure measurements and the change in the amount of gas, and determining a first fluid level based on the first volume of the chamber.

Abstract: A method of fabricating a drill bit is described. The method includes forming a mold with interior surfaces defining a mold cavity within the mold, the mold cavity having a shape corresponding to a shape of a body of the drill bit; forming catalyst-free synthesized polycrystalline diamond compact (PDC) cutting elements using an ultra-high pressure and temperature process; determining positions of the catalyst-free synthesized PDC cutting elements within the mold cavity; placing the catalyst-free synthesized PDC cutting elements at the determined positions within the mold cavity; filling the mold cavity with matrix materials of the body of the drill bit; and bonding the catalyst-free synthesized PDC cutting elements with the matrix materials of the body to form an impregnated drill bit.

Abstract: Methods for forming a polycrystalline diamond compact (PDC) drill bit from catalyst-free synthesized polycrystalline diamonds are described. The polycrystalline diamonds are deposited within a mold. In some cases, a matrix body material is deposited within the mold, and an infiltration process is performed to bond the polycrystalline diamonds to the matrix body material to form the PDC drill bit. In some cases, a drill bit body is formed within the mold, and forming the drill bit body within the mold includes depositing a layer of matrix body material particles within the mold, depositing an adhesive ink within the mold, and curing the adhesive ink. In some cases, a sintering process is performed after forming the drill bit body to remove at least a portion of the adhesive ink and increase a density of the drill bit body to form the PDC drill bit.

Abstract: A system includes a sliding sleeve, a ball landing seat, microchips, a ball catcher, and a charging ring. The sliding sleeve is installed within a tubular body. The tubular body has an exit groove. The ball landing seat is formed by the sliding sleeve and is configured to receive a ball. The plurality of microchips are housed in a microchip ring installed within the sliding sleeve. The plurality of microchips are configured to be released into the well to gather data upon reception of the ball in the ball landing seat. The ball catcher is configured to receive and hold the ball after the plurality of microchips are released into the well. The charging ring is electronically connected to the microchip ring and has a circuit, a power source, and a charging coil. The circuit has a voltage regulation chip, a microprocessor, and a circuit motion sensor.

Abstract: An intelligent drilling system is disclosed. The intelligent drilling system includes an inner drill pipe adapted to rotate around a longitudinal axis in a transversal plane of a wellbore to advance a drill bit during a drilling operation, an external drill string shield surrounding the inner drill pipe and coupled to the inner drill pipe via at least one bearing system, the at least one bearing system adapted to decouple the external drill string shield from a rotational motion of the inner drill pipe in the transversal plane such that the external drill string shield remains substantially stationary during the drilling operation, and an in-situ sensing system disposed on an interior wall of the external drill string shield to measure at least one downhole parameter of the wellbore.
