  • Patent number: 10808166
    Abstract: A composition and method for treating a fracturing fluid comprising produced water with high levels of dissolved solids using a polymer crosslinked with a boron compound and a high pH alkylamine buffer. The composition improves the viscosity stability of the fracturing fluid at elevated bottom-hole temperatures, particularly when the fluid has high levels of calcium and magnesium. The composition is particularly useful with polysaccharides, including galactomannan gums, such as guar gum, locust bean gum, and karaya gum, and allows for the use of the preferred boron compound crosslinkers in high total dissolved solids fracturing fluids without the pH destabilization problems encountered with the prior art.

In some embodiments, the degradable composite composition comprises a degradable polymer mixed with discrete particles of a filler that acts to accelerate the degradation of the degradable polymer. Such materials degrade in 60 C water in less than 30 days, <14 days, and even <7 days. Various materials are provided that can degrade equally fast at lower temperatures, such as 50 C, or even 40 C.

  • Patent number: 9416620
    Abstract: A method for cementing a tubular string into a wellbore from a drilling unit includes: running the tubular string into the wellbore using a workstring; hanging the tubular string from a wellhead or from a lower portion of a casing string set in the wellbore; and pumping cement slurry through the workstring and tubular string and into an annulus formed between the tubular string and the wellbore. The method further includes, during thickening of the cement slurry: circulating a liquid or mud through a loop closed by a seal engaged with an outer surface of the workstring, the closed loop being in fluid communication with the annulus, and periodically choking the liquid or mud, thereby pulsing the cement slurry.

  • Patent number: 9151417
    Abstract: A pipe lining composition and a method for installing the pipe lining composition into a pipeline requiring repair is provided. The lining composition is a layered lining composite formed of alternating plies of felt and carbon fiber strand reinforcing such that layers of carbon fiber reinforcing strands are trapped between layers of felt. Once the composite is laid up the composite is preferably stitched to provide stability and to maintain the layers relative to one another and then formed into a tube. In accordance with the method, the lining tube is then sequentially filled resins of increasing viscosity as it is drawn through rollers in a manner that fully wets out the carbon fiber before it is placed into the pipe to be lined.

  • Publication number: 20150136392
    Abstract: A one trip interventionless method for fracking multiple intervals incorporates a remotely operated passage isolation valve for each interval. A screen backed by a base pipe is provided to route screened production through a shutoff valve before the production reaches the passage in the completion assembly. The shutoff valve is remotely operated as well. The fracking port is associated with a pressure responsive operator such as a j-slot mechanism with a spring return. The j-slot mechanism is behind a rupture disc so that it remains unaffected while other operations are going on in the wellbore. The rupture discs are set at different pressures for the intervals involved. Sequentially, each fracked zone is isolated and the zone above is opened with breaking the rupture disc and applying predetermined number of pressure cycles. The screen valves are remotely operated as needed after the fracking to initiate production from one or more intervals.

  • Publication number: 20150083421
    Abstract: The present invention is a valve tool utilized for hydraulically fracturing multiple zones in an oil and gas well without perforating the cement casing. An oil/gas well completion method involves the use of a valve that is installed as part of the casing string of the well. A mandrel-less casing provides for cement flow within the casing when the valve element is in a closed position and allows for axial flow of fracturing fluid through the cement casing to fracture the formation near the valve when the sleeve is open. The invention disclosed herein is an improved valve used in this process.
