Abstract:

Various embodiments of the invention provide human vesicle-associated proteins (VAP) and polynucleotides which identify and encode VAP. Embodiments of the invention also provide expression vectors, host cells, antibodies, agonists, and antagonists. Other embodiments provide methods for diagnosing, treating, or preventing disorders associated with aberrant expression of VAP.

International Classification:

E21B 43116

US Classification:

166297

Abstract:

In a subterranean well a one-trip production zone perforation and proppant fracturing operation is carried out using a workstring-supported perforation gun lowered into a casing nipple located in the production zone. Firing of the gun creates spaced apart aligned sets of perforations extending outwardly through a side wall portion of the workstring, the nipple, the surrounding cement, and into the production zone, after which the gun falls into and is retained in an underlying gun catcher portion of the workstring. While an overpull force is maintained on the workstring above the perforations, a proppant slurry is pumped down the workstring, out its sidewall perforations, and outwardly through the aligned perforation sets formed in the nipple, cement and production zone. After stimulation of the production zone, the workstring and the spent perforation gun that it retains are pulled up, with the upwardly moving workstring positioning a sliding closure device inwardly over the perforations to isolate the stimulated production zone until the well is readied for production. Illustrated alternate embodiments include the use of a low debris casing gun in place of the drop-off type perforating gun, the use of pre-formed wide wall perforations in the workstring side wall, and a one-trip perforation and production flow creating method in which the production zone stimulating step is eliminated.

International Classification:

E21B 33128

US Classification:

277230

Abstract:

A seal and seal assembly for use with well tools, such particularly as well packers, for sealing the annulus between the well packer mandrel and the wall of a well tubing such as casing. The seal is fabricated of an elastomeric-like material comprising fluorocarbon resins, poly arylene ketone, and carbon fibers mounted between end retainer assemblies each comprising a mesh anti-extrusion ring, a tapered mesh backup ring, and a metal backup shoe. The seal has internal longitudinally spaced V-shaped recesses to cause the seal to buckle radially outwardly as it is compressed longitudinally to increase the stress along the middle portion of the seal where the seal meets the well casing inner wall. The seal is useful at high temperatures and pressures such as 550 degrees F. and greater than 15,000 psi.

International Classification:

F21B 2304

US Classification:

166120

Abstract:

A hydraulically set well packer. The setting sleeve is releasably locked to the packer mandrel to prevent premature setting while the packer is being lowered to its desired downhole location. The setting sleeve is unlocked by increasing fluid pressure within the packer mandrel above a preselected value. The length of the setting sleeve can be easily adjusted to accommodate additional piston units, changes in mandrel length, and various packing elements.
