Abstract: A system for monitoring a foundation includes a sensor cartridge assembly. The sensor cartridge assembly includes a sensor disposed in a sensor tube and a sensor head attached to an end of the sensor tube. Wiring coupled to the sensor and routed in the sensor tube to the sensor head conveys power and/or telemetry between the sensor and a controller. The sensor tube is configured to be inserted into a raceway attached to a foundation. The raceway may be within the foundation and/or located at a perimeter of the foundation. A method for monitoring a foundation includes deriving an elevation of the foundation at the location of the sensor based on pressure measurements made by the sensor within the sensor tube.

Abstract: Methods, apparatus, and systems are provided for correcting, or at least adjusting, for drill pipe compression in a downhole operation in a wellbore. An exemplary method includes obtaining an indication of a first displacement, from a base position, of a first portion of a drill string due to a first force being applied to the first portion of the drill string and a second portion of the drill string being stationary; obtaining an indication of the first force; obtaining an indication of a second displacement, from the base position, of the first portion of the drill string due to a second force being applied to the first portion of the drill string while performing a downhole operation; obtaining an indication of the second force; and determining a displacement of the second portion of the drill string, based on the first displacement, the second displacement, the first force, and the second force.

Abstract: A method of controlling a downhole operation includes: deploying a work string into a wellbore, the work string comprising a deployment string and a bottomhole assembly (BHA); digitally marking a depth of the BHA; and using the digital mark to perform the downhole operation.

Abstract: Embodiments of methods and apparatuses to measure a concrete foundation from within the concrete in order to maintain the foundation in a controlled flat condition over time we disclosed. A method, for example, may include placing a conduit network inside forms of a concrete foundation, documenting the conduit network in X and Y coordinate system, pouring the concrete foundation with the conduit network inside the concrete in generally the same position, passing an elevation measuring sensor through the conduit network to record a baseline elevation of the conduit and using this baseline for relative comparisons in the future. An embodiment of a method also may include using the relative change in the conduit elevation to predict the relative risk of a repair and financial losses and using the relative change in the conduit elevation to assist in the proper repair and maintenance of the foundation.

Abstract: An excavation system for forming a wellbore through a subterranean formation, the system employing pressurized drilling fluid with impactors mixed therein. The pressurized fluid with impactors is directed to a drill string having a drill bit with nozzles on its lower end. The fluid impactor mixture is discharged from the nozzles and against the formation, wherein the impactors contact, compress, and fracture the formation to excavate through the formation. The system includes an impactor injection system that injects impactors into a stream of pressurized drilling fluid to form the mixture. The injection system operates at substantially the same pressure as the pressurized drilling fluid.

Abstract: A method and system of subterranean excavating that estimates a buoyancy force applied to a downhole excavating system from drilling fluid. The estimated buoyancy force is used to derive a true weight on bit (WOB) at the borehole bottom. The derived realized WOB is compared to a target WOB to obtain a change in WOB. Based on the change in WOB, the excavating system is adjusted so the realized WOB approximates the target WOB. The excavating system adjustment includes applying a compensating force to the string. Compensating forces can be produced by manipulating a block assembly or deploying a thruster device in the string.
