  • COMPOSITIONS AND METHOD FOR TREATING OUT HYDROGEN SULFIDE AND PREVENTING SETTLING OF PRECIPITATE IN AN ENVIRONMENTALLY RESPONSIBLE DRILLING AND PACKER FLUID
    Publication number: 20170152431
    Abstract: An environmentally responsible iron chelating additive and method for removing hydrogen sulfide or sulfide ions from drilling and packer fluids and preventing settling of precipitates. Iron chelating agents selected from the group consisting of ferrous lactate, ferrous gluconate, ferrous bis glycinate, ferrous citrate, ferrous acetate, ferrous fumarate, ferrous succinate, ferrous sacchrate, ferrous tartarate, ferrous glycine sulfate, ferrous glutamate, ferrous ascorbate, ferrous polymaltose, or a combination thereof, may be used. When the fluids are oil based, the iron chelating agents are added to the water phase of an emulsion, and the emulsion is added to the fluid. Viscosifiers may also be added to the drilling fluid with the emulsion.
    Type: Application

  • Method and apparatus for drilling and completion fluid separation
    Patent number: 9500051
    Abstract: A method and apparatus for separating drilling or completion fluids is described. The apparatus may include a fluid container that is operable to at least temporarily contain a drilling or completion fluid. The fluid container may have an inlet port and at least one outlet port. The apparatus may further include an excitation element. The excitation element may be operable to impart a pre-determined vibratory force on the drilling or completion fluid within the fluid container.
