Abstract: A dynamic range relaxation algorithm is applied to simulate borehole failure under a variety of stress conditions. The borehole and its neighborhood are modeled by a number of regions by a plurality of interconnected nodes. The bonds between the nodes may be modeled as springs, rods, or beams. The strength of the bonds has a statistical variation to accurately simulate real world situations. The model may include, in addition to the borehole and the far earth formations, a liner, a casing, and/or a gravel pack. Simulation is carried out for different strength of the bonds.

Abstract: Capillary pressure curves can be derived from nuclear magnetic resonance (NMR) pore size distributions. These derived capillary pressure curves can be used to derive the displacement pressure, the fractional bulk volume of mercury at infinite pressure and a geometrical factor. These factors can be used to accurately predict permeability from an NMR derived capillary pressure curve.

Abstract: Refining processes for recovering HF from acid soluble oils (ASO) generated by the HF recovery unit of an HF alkylation unit are provided. ASO containing HF is removed from the HF recovery unit and contacted with water to form a system having two phases, an aqueous HF containing phase and an organic phase. After phase separation, the aqueous HF containing phase passes through a bed of fluidized NaF crystals, where the NaF reacts with the HF to form salts having the general formula NaF.nHF. Flow of the aqueous HF containing phase to the bed continues until exhaustion of the bed, as determined by the detection of HF in the effluent. After exhaustion of the bed, the process provides for the regeneration of the bed and release of anhydrous HF which is then returned to the HF alkylation unit.

Abstract: A borehole system for operating a downhole generator suspended on a composite coiled tubing string. The coiled tubing has at least two separate longitudinal chambers to provide separate flow paths. A fluid is pumped from the surface through one flowpath to drive a downhole turbine powered generator for operating downhole systems. A second flowpath in the tubing is used to return fluids to the surface. The non-metal environment of the composite coiled tubing provides a non-magnetic environment in which to operate wellbore devices. Data is transmitted to the surface by way of a fiber optic conductor.
