  • Patent number: 10758884
    Abstract: A method for preparing concentrated and stable nanoparticle organosols using phase transfer is disclosed. The method includes transferring nanoparticles from a hydrosol into a hydrocarbon carrier with the aid of a transfer agent. The transfer agent can be added before, during or after the reaction of nanoparticle preparation and can be added to the aqueous or the organic carrier. The nanoparticles may be prepared in situ, pre-prepared in-house or commercially available. At the optimum values of the different parameters; namely precursor concentrations, amount of transfer agent and concentration of nanoparticles in the organosol, complete transfer of the nanoparticles may be achieved. The approach employs room temperature, moderate mixing and minimum number and quantity of chemicals relative to prior art. The nanoparticles may be used in fluids used in oil and gas recovery including drilling, completion, and stimulation fluids.

  • Patent number: 9920233
    Abstract: There is described a drilling fluid for wellbore strengthening having nanoparticles and granular particles. In one aspect described herein, the drilling fluid is an invert emulsion based fluid. In a further aspect, the nanoparticles are iron hydroxide or calcium carbonate, and in a further aspect from about 1 to 30 nm in size. In one aspect described herein, the granular particles are graphite or calcium carbonate and in a further aspect, up to 250 ?m in size. The nanoparticles and granular particles plug fractures in the wellbore to strengthen the wellbore.

  • Patent number: 9701885
    Abstract: A use of nanoparticles in a well fluid for improved lubricity is disclosed herein. The nanoparticles are present in the well fluid in low amounts below 5 wt %. The nanoparticles may be formed ex situ and added to the fluid or in situ in the fluid. In one aspect, the well fluid is a drilling fluid. In a further aspect, the well fluid is an invert emulsion based fluid or an aqueous based fluid.
