Abstract: A method of planning and/or performing an energy industry operation includes estimating variable coefficient of friction (CoF) functions defining the variation of a CoF as a function of a downhole condition dependent on a selected operational parameter of an energy industry operation, the operation including deploying a downhole component configured to perform the operation, each variable CoF function associated with a different value of the selected operational parameter.

Abstract: An embodiment of a method of performing an energy industry operation includes: deploying a carrier in an earth formation, the carrier including a downhole component configured to perform the operation; performing the operation according to operational parameters; measuring a condition, the condition including at least one of a surface condition and a downhole condition, and generating measurement data representing the measured condition; tuning a simulation model of the operation based on the measurement data, the model being a mathematical model configured to estimate the condition based on the selected operational parameters; selecting a hypothetical adjustment to one or more selected operational parameters; applying the hypothetical adjustment to the simulation model to generate predicted conditions of the operation; and based on the predicted conditions representing an improvement to the operation, adjusting operational parameters according to the hypothetical adjustment.

Abstract: A liquid-vapor contact apparatus has pairs of vertical outer walls disposed in the manner of the vertical faces of a cuboid. The apparatus includes a plurality of spaced, parallel, vertical plates. Between each pair of adjacent plates there is a packing comprising a vertical array of corrugated liquid-vapor contact elements of the type that are used in structured packing. The corrugations in each element slope from top to bottom in a direction opposed to that in which the corrugations in contiguous elements slope. The two outermost plates form the walls of the apparatus. The walls comprise alternate edge portions of plates and of spacer bars. The plates define first and second sets of passages, respectively. One set of passages performs a first fractionation duty, and the other set another fractionation duty.

Abstract: A liquid-vapour contact apparatus has pairs of vertical outer walls disposed in the manner of the vertical faces of a cuboid. The apparatus includes a plurality of spaced, parallel, vertical plates. Between each pair of adjacent plates there is a packing comprising a vertical array of corrugated liquid-vapour contact elements of the type that are used in the assembly of structured packing, and having the apexes of the elements in fluid tight engagement with the respective plates. The corrugations in each element slope from top to bottom in a direction opposed to that in which the corrugations in contiguous elements slope. The two outermost walls form the walls of the apparatus. The other walls comprise alternate edge portions of plates and of spacer bars. Liquid is distributed appreciably evenly between the passages formed by adjacent vertical plates at the top of the apparatus and flows over the elements and effectively vertically downwards.

Abstract: A liquid-vapor contact apparatus for use in distilling air on board a ship has vertical outer walls disposed in the manner of the vertical faces of a cuboid. The apparatus includes a plurality of spaced, parallel, vertical plates. Between each pair of adjacent plates there is a plurality of spaced, generally horizontal, liquid-vapor contact members each including a horizontal tray member and having edges and in fluid-tight engagement with the respective plates. There are a plurality of downcomers for conducting liquid from tray member to tray member, there being separate flow paths for liquid between each pair of adjacent plates. The two outermost plates form one pair of walls of the apparatus. The other pair walls comprises alternate edge portions of plates and spacer bars (or members).
