Abstract: A cable protection apparatus can include a collet having a collet body and a collet bore, where the collet bore traverses through the collet body along its length, where the collet body is radially compressible along the collet length, where the collet bore has a reduced diameter when the collet body is compressed. The cable protection apparatus can also include an enclosure having an enclosure body, an enclosure bore, an enclosure channel, and an adjustment feature, where the enclosure bore traverses through the enclosure body along its length, where the enclosure channel traverses a thickness of the enclosure body to the enclosure bore along the enclosure length, where the enclosure bore traverses a receiving chamber disposed within the enclosure body, where the receiving chamber is configured to receive the collet, where the adjustment feature manipulates the enclosure body to apply a force to compress the collet body.

Abstract: A wireline standoff can include a base comprising a base body having a base channel that traverses a thickness of the base body along its length, where the base channel has a width and a depth that are large enough to receive the wireline. The wireline standoff can also include an end piece having an end piece body having an end piece channel that traverses a thickness of the end piece body along the end piece length, where the end piece channel has a width and a depth that are large enough to receive the wireline. The base and the end piece are in a default position when the base channel and the end piece channel are aligned and in a secured position when the end piece is moved relative to the base so that the base channel and the end piece channel are misaligned with each other.

Abstract: A method is described for quantitative pay summaries from mud logs, real-time fluid typing, and to minimize logging expense in high-angle or horizontal wells. The method may include receiving at least one mud log; selecting extraction system type, operating, and drilling parameters for the at least one mud log; determining hydrocarbon parameters such as methane (C1) extraction efficiency, trap response factor (TRF), and relative responses for ethane-pentane (C2-C5); correcting gas-in-mud volume to an earth surface to generate a corrected C1-C5; calculating a gas-to-oil ratio (GOR) from the corrected C1-C5; calculating a reservoir gas volume from the gas-in-mud volume to an earth surface and the GOR; determining pay cutoffs; and generating least one pay summary. The method may be executed by a computer system.

Abstract: Desirable completion zones can be identified using closure stress in combination with one or more other attributes such as porosity. One computer-based well placement method includes using the computer to: process a seismic data volume to map the spatial distribution of a seismic-based CSS attribute; acquire logs from one or more boreholes in the subsurface region; derive from the logs a relationship between CSS and a minimum in-situ stress; apply the relationship to the CSS attribute map to produce a landing map that highlights desirable completion zones; and place one or more wells in the desirable completion zones. The borehole logs may include direct measurements of minimum in-situ stress (acquired via microfracture testing), sonic tool measurements of P-wave and S-wave velocity, and density tool measurements of bulk formation density.
