Abstract
Aspects of the present disclosure generally relate to new drilling compositions and uses thereof. In an aspect, a water-based drilling mud composition is provided. The water-based drilling mud composition includes an aqueous carrier, asphalt sulfonate salt particles, a base oil, and graphene particles. In another aspect is provided a process that includes introducing a composition comprising asphalt sulfonate salt particles, a base oil, and graphene particles to a subterranean formation.
Claims28
A water-based drilling mud composition, comprising:
- an aqueous carrier;
- asphalt sulfonate salt particles;
- graphene particles;
- and
- a base oil, wherein the graphene particles and the base oil are dispersed in the composition to promote stability of an emulsion.
A process, comprising:
- introducing a composition comprising asphalt sulfonate salt particles, graphene particles, and a base oil to a subterranean formation.
A water-based drilling mud composition, comprising:
- an aqueous carrier;
- asphalt sulfonate salt particles;
- graphene particles;
- and
- a base oil,
- wherein the graphene particles and the base oil are dispersed in the composition to promote stability of an emulsion, and wherein the water-based drilling mud composition has a COF (measured at 100° F.) that is at least 5% less than a COF of the water-based drilling mud composition without the graphene particles.
A method of reducing torque and drag on drilling equipment when drilling, the method comprising:
- introducing a composition comprising asphalt sulfonate salt particles, graphene particles, and a base oil to drilling equipment in a subterranean formation;
- and
- causing movement of the drilling equipment, wherein the movement of the drilling equipment experiences less torque and drag than movement of the drilling equipment without the composition.
A method of forming a tribofilm on drilling equipment, the method comprising:
- introducing a composition comprising asphalt sulfonate salt particles, graphene particles, and a base oil to drilling equipment to form a tribofilm on a surface of the drilling equipment.
A method of drilling an extended lateral wellbore, the method comprising:
- introducing a composition comprising asphalt sulfonate salt particles, graphene particles, and a base oil to drilling equipment in a subterranean formation;
- and
- drilling an extended lateral wellbore with the drilling equipment in the subterranean formation.
