Claims3
An altered drilling fluid, comprising:
- a drilling fluid;
- and
- a lost circulation material (LCM), wherein the LCM comprises:
- a first plurality of particles produced from date tree seeds, wherein each of the first plurality of particles produced from date tree seeds has a diameter in the range of 500 microns to 4000 microns;
- and
- a second plurality of particles produced from scrap tires, wherein each of the second plurality of particles produced from scrap tires has a diameter in the range of 2000 microns to 8000 microns,
- wherein the LCM has a concentration of at least 20 parts-per-billion in the altered drilling fluid, and wherein the LCM has a coefficient of resiliency of at least 0.5 and prevents the loss of whole mud in a lost circulation zone in a wellbore.
