Abstract
The present invention generally relates to compositions of matter and methods of using those compositions. More particularly, and as part of one of the preferred embodiments, the present invention relates to compositions and methods of use of fluids useful for sealing formation fractures and/or inhibiting downhole fluid loss. The present invention is useful as a pill or series of pills that can be formulated and spotted to a particular formation zone.
Claims253
A fluid system, comprising:
- a continuous liquid phase;
- a lost circulation material;
- and
- said lost circulation material comprising hollow particles that assist in effectively sealing a formation.
A fluid system, comprising:
- a continuous liquid phase;
- a lost circulation material;
- and
- said lost circulation material comprising a dilatant additive that assists in effectively sealing a formation by contributing to the deliquification of the fluid within the formation.
A fluid system, comprising:
- a continuous liquid phase;
- a lost circulation material;
- and
- said lost circulation material comprising aggregate particles that assist in effectively sealing a formation by contributing to the deliquification of the fluid within the formation.
A fluid system, comprising:
- a continuous liquid phase;
- a lost circulation material;
- said lost circulation material comprising aphrons that assist in effectively sealing a formation;
- and
- a pill that includes said aphrons.
A method of sealing a formation comprising:
- introducing a fluid into the formation, said fluid having a continuous liquid phase;
- and
- utilizing a lost circulation material in said fluid, said lost circulation material comprising hollow particles that assist in effectively sealing the formation.
A method of sealing a formation comprising:
- introducing a fluid into the formation, said fluid having a continuous liquid phase;
- and
- utilizing a lost circulation material in said fluid, said lost circulation material comprising a dilatant additive that assists in effectively sealing the formation by contributing to the deliquification of the fluid.
A method of sealing a formation comprising:
- introducing a fluid into the formation, said fluid having a continuous liquid phase;
- deliquifying the fluid within the formation;
- and
- utilizing a lost circulation material in said fluid, wherein said lost circulation material comprises aggregate particles that assist in effectively sealing the formation.
A method of sealing a formation comprising:
- introducing a fluid into the formation, said fluid having a continuous liquid phase and forming a pill that sits downhole for a period of time sufficient for the pill to begin to soak into the formation;
- and
- utilizing a lost circulation material in said pill, said lost circulation material comprising aphrons that assist in effectively sealing the formation.
A method of sealing a formation comprising:
- introducing a fluid into the formation, said fluid having a continuous liquid phase;
- utilizing a lost circulation material in said fluid that assists in effectively sealing the formation;
- and
- creating a tortuous bed within the formation.
A method of sealing a formation comprising:
- introducing a fluid into the formation, said fluid having a continuous liquid phase;
- utilizing a lost circulation material in said fluid that assists in effectively sealing the formation;
- and
- deliquifying the fluid within the formation.
