Abstract: Oil residues are removed from contaminated solids, in particular from cuttings produced from drilling a borehole using an oil-based drilling fluid, by contacting the solids with a washing fluid which comprises carbon dioxide and cosolvent under conditions at which carbon dioxide is a supercritical fluid and the cosolvent is in solution in the supercritical carbon dioxide and then separating washed solids from the washing fluid; wherein the washing fluid comprises at least 5% by volume of cosolvent which is one or more organic compounds with a Hildebrand solubility parameter in a range from 16 to 21 MPa1/2. The washing process may be applied to drilling cuttings produced offshore.

Abstract: A method for measuring average thickness of a metal or alloy coating on a metal or alloy substrate using an X-ray fluorescence (XRF) spectrometer is used when the coating has an uneven surface at different distances from a measurement window of the XRF spectrometer. The method includes measuring elemental composition of the coating or substrate using the XRF spectrometer and obtaining the average thickness of the coating using a calibration relationship between coating thickness and elemental composition of the coating or substrate. The metal or alloy coating may be a metal or alloy coating of a plurality of outer armor wires wrapped around a cable. The method may be used to analyze coating thickness changes over time or along the length of the cable, or to analyze a corrosive environment in order to choose optimal material for a metal or alloy coating.

Abstract: A method for measuring a thickness of a deposit layer on a metal or alloy substrate using an X-ray fluorescence (XRF) spectrometer, where the deposit layer includes scale deposits or corrosion products. As part of the method, an elemental composition of the deposit layer or the metal or alloy substrate is measured using the XRF spectrometer. The thickness of the deposit layer is obtained from the elemental composition using a calibration relationship between deposit layer thicknesses and corresponding elemental compositions of the deposit layer or the metal/alloy substrate. The method can be applied to determine the rate of deposit layer formation and evaluate the effectiveness of a treatment.

Abstract: A method of inhibiting corrosion of duplex stainless steel by aqueous acidic solution, comprises carrying out a preliminary treatment which is passivation of the steel while exposing the steel to a first aqueous acidic solution containing at least one organic corrosion inhibitor able to adsorb to a steel surface, so as to deposit a passivating and corrosion inhibiting film on the steel surface; and thereafter during a second period of time exposing the steel to a second aqueous acidic solution different from the first aqueous acidic solution and also containing at least one organic corrosion inhibitor able to adsorb to a steel. The second aqueous acidic solution maintains the film on the steel surface, such that weight loss through corrosion in the second period of time is lower than the weight loss which would be observed with the same second aqueous acidic solution but without carrying out the preliminary treatment.

Abstract: A method for forming proppant aggregates, for example downhole in an injection well, includes injecting a slurry including a thermo-responsive polymer with a low critical solution temperature and a proppant downhole, and heating the slurry above the low critical solution temperature of the polymer. The heating of the slurry above the low critical solution temperature of the polymer aggregates the proppant. A composition of the slurry includes a carrier fluid including a thermo-responsive polymer, a proppant, and optional additives.

Abstract: A wellbore fluid is an aqueous carrier liquid with first and second hydrophobic particulate materials suspended therein. The first hydrophobic particles have a higher specific gravity than the second hydrophobic particles and the fluid also comprises a gas to wet the surface of the particles and bind them together as agglomerates. The fluid may be a fracturing fluid or gravel packing fluid and the first particulate material may be proppant or gravel. The lighter second particulate material and the gas both reduce the density of the agglomerates which form so that they settle more slowly from the fluid, or are buoyant and do not settle. This facilitates transport and placement in a hydraulic fracture or gravel pack. One application of this is when fracturing a gas-shale with slickwater. The benefit of reduced settling is better placement of proppant so that a greater amount of the fracture is propped open.

Abstract: An aqueous acid composition that may be used, for example, in a matrix acidizing treatment can include an acid, a polymeric acid corrosion inhibitor, and an acid corrosion inhibitor intensifier. The acid corrosion inhibitor can include iodide ions and metal ions, with the metal ions being one or more of copper, silver, bismuth, or antimony. The molar ratio of metal ions to iodide ions can be 1:X, where X is greater than or equal to 2. The polymer of the polymeric acid corrosion inhibitor can have a molecular weight less than 100,000 g/mol.
