Abstract: The disclosure pertains to installing a plurality of tear cords between a metal tube and a protective jacket. The multiple cords facilitate ease of removal of the protective jacket by creating a panel of the jacket that is detached from the remainder by pulling on the multiple tear cords. The resulting widened space can be used to remove the tube from the remaining protective jacket. The jacketed tubes may be used in a hydrocarbon production downhole well bore. The tubes may be used to furnish hydraulic fluid or chemicals into the well bore. The contents may be pressurized or under vacuum. The jacketed tubes are hermetically sealed. The tubes, which may be 1 inch in diameter, are joined using compression fittings. Tear cords are used to facilitate removal of the protective jacket without damage to the tube surface thereby facilitating the placement of compression fittings and maintaining the integrity of the tube wall.

Abstract: The protective cover disclosed in this application is used in oil and gas production wells. It may be used in other types of wells or in other industrial application utilizing piping and capillary tubes, signal or electrical power cables. Multiple capillary tubes, jacketed tubes and signal or power cables extend from the well head down into the well bore. The cables and tubes run on the outside of the production piping and inside the well casing. The protective cover comprises cast metal wherein the length of the cover is oriented parallel to the longitudinal axis of at least two pipe segments and a connector collar. The cover comprises 2 sides and a top thereby creating an interior channel. Each end of the channel is open. The cable(s) or tube(s) may enter the protective cover from one open end, continue within the channel under the cast metal top, and exit from the opposite open end of the protective cover.

Abstract: A system, apparatus, and method for determining real time bubble point pressure and compressibility of a fluid originating from a subsurface earth formation during well production first permit remote collection of a sample of fluid. The sample of fluid is then remotely expanded, while the temperature, pressure, and volume of the sample of fluid are remotely monitored. The real time bubble point pressure and compressibility of the sample of fluid are extracted from a plot of sample fluid pressure versus volume, which exhibits substantially linear behavior having two different slopes.

Abstract: A method of determining the real time bubble point pressure of a fluid originating from a subsurface earth formation using an adjustable choke positioned downhole adjacent to the formation. The adjustable choke is placed into communication with the wellbore fluid flowing from the formation to the surface. The adjustable choke has a remotely adjustable choke opening for selectively restricting the flowrate of the fluid flowing through the choke. The adjustable choke has a pressure sensor for measuring the fluid pressure downstream of the choke opening. The method includes obtaining downstream fluid pressure data as a function of choke size for generating a plot of downstream pressure versus choke size data which exhibits substantially linear behavior having two different slopes.
