Claims43
A method of performing drilling operations comprising:
- circulating a drilling fluid comprising zeolite and a carrier fluid in a wellbore penetrating a subterranean zone, wherein the zeolite is present in the drilling fluid in an amount of from about 1% to about 50% by volume, and comprises chabazite.
A method of performing drilling operations comprising:
- circulating a drilling fluid comprising zeolite and a carrier fluid in a wellbore penetrating a subterranean zone wherein the zeolite comprises chabazite;
- and
- suspending, in the drilling fluid, one or more of cuttings, a weighting agent, and loss circulation material.
A method of performing drilling operations comprising:
- drilling a wellbore penetrating a subterranean zone with drilling fluid comprising zeolite and a carrier fluid, wherein the zeolite is present in the drilling fluid in an amount of from about 1% to about 50% by volume, and comprises chabazite;
- leaving a portion of the drilling fluid in one or more of a filter cake, a fissure, a fracture, a cavern, a vug, a thief zone, a low pressure subterranean zone and a high pressure subterranean zone;
- and
- causing the zeolite in the left portion of the drilling fluid to set.
