Abstract
A drilling fluid system that combines a carbon black/asphaltite/lignite mixture with a fish oil/glycol mixture; and a method for manufacturing a drilling fluid system that could be utilized with pre-existing water based muds during drilling and excavating applications.
Claims93
A drilling fluid system comprising:
- (a) a hydrophilic clay;
- (b) a pH controller;
- (c) a fluid loss controller;
- (d) a first dispersant;
- (e) a mixture of carbon black, asphaltite, lignite, and either a first surfactant or a second dispersant;
- and
- (f) a mixture of a second surfactant, an oil, an ester alcohol and polypropylene glycol.
A drilling fluid system utilized with a pre-existing water based mud for use in drilling applications, said system comprising:
- (a) a mixture of carbon black, asphaltite, and lignite and either a first surfactant or a dispersant;
- and
- (b) a mixture of a second surfactant, an oil, an ester alcohol and polypropylene glycol.
A method of manufacturing a drilling fluid system, said method comprising the steps of:
- (a) mixing water with a hydrophilic clay, a weighting agent, a pH controller, a fluid loss controller, and a dispersant;
- (b) admixing a mixture of carbon black, asphaltite, and lignite and either a surfactant or a dispersant to the mixture in (a);
- and
- (c) admixing a mixture of a nonionic surfactant, an oil, an ester alcohol and a polypropylene glycol to the mixture of (a) and (b).
A method of manufacturing a drilling fluid system to be used with a pre-existing water based mud for drilling and excavating applications, said method comprising the steps of:
- a) preparing a mixture of carbon black, asphaltite, lignite, and either a surfactant or a dispersant;
- b) preparing a mixture of a nonionic surfactant, an oil, an alcohol, and polyproplyene glycol;
- and
- c) adding the mixture of (a) and (b) to a pre-existing water based mud.
