    Abstract: Methods for treating subterranean wells in which the producing formation is a carbonate comprise preparing a treatment fluid comprising either: (a) an aqueous solution of a multivalent-cation reacting polymer; (b) a solution comprising a fatty acid and an ethanolamine; (c) an aqueous acidic solution of one or more compounds whose calcium salts are insoluble; or (d) an aqueous solution comprising urea or alkane derivatives thereof or both and polyvinylpyrrolidone (PVP). The treatment fluid is placed in the well such that the solution contacts the carbonate formation at a pressure higher than or equal to the fracturing pressure. The treatment fluid is allowed to react with the carbonate formation, thereby depositing a film onto the formation surface or parts of the formation surface. Then an acid solution is placed in the well such that the acid contacts the carbonate formation at a pressure higher than or equal to the fracturing pressure.

    Abstract: A method of reservoir analysis for a reservoir of interest, which includes obtaining a crude oil sample originating from the reservoir of interest. Oil-water interfacial tension of the crude oil sample is measured. An empirical model that relates oil-water interfacial tension of the crude oil sample to concentration of at least one organic acid species in the crude oil sample is calibrated based on the measured oil-water interfacial tension of the crude oil sample. The concentration of the at least one organic acid species in the crude oil sample may be absolute or relative. At least one reservoir parameter characteristic of the reservoir of interest can be calculated based on the calibrated empirical model.

    Abstract: An expandable tool includes a body and a recess extending at least partially through the body from an outer radial surface of the body. A spline insert may be at least partially positioned in the recess and coupled to the body. The spline insert may include a single spline or multiple splines. A cutter block or other expandable member may be at least partially positioned in the recess. The cutter block or other expandable member may include a spline on a side surface thereof, which spline may be engaged with the one or more splines of the spline insert. Engagement between one or more splines of the spline insert and spline of the cutter block or other expandable member may allow the expandable member to move radially outward from a retracted position to an expanded position, and vice versa.

    Abstract: High reliability power cables for subsea application are provided. Example power cables provide enhanced resistance to partial discharge dielectric breakdown as well as resistance to explosive gas decompression, by eliminating micro-defects and voids at the interface between the insulation layer and the barrier layer during the cable manufacturing process. Lead metal, which is conventionally extruded as a primary barrier layer, is replaced in the example power cables by a gas-and-fluid-resistant thermoplastic that is co-extruded or tandem extruded with surface-modified insulation to promote bonding between the two layers. Elimination of lead metal in the example power cables also significantly reduces their overall weight. The improved resistance to partial discharge and resistance to rapid gas decompression translates to lower workover and lower cost of ownership.

    Abstract: A method for magnetic ranging includes rotating a downhole tool in a drilling well in sensory range of magnetic flux emanating from a target well. The downhole tool includes a magnetometer set and an accelerometer set rotatably coupled to the tool. The magnetometer set and the accelerometer set acquire corresponding magnetometer measurements and accelerometer measurements while rotating. The magnetometer measurements are transformed to a rotation independent reference frame to obtain rotation invariant measurements which are in turn processed to compute at least one of a distance and a direction from the drilling well to the target well.
