## Abstract

A hybrid particle mix lost circulation material (LCM) is provided. The hybrid particle mix LCM includes date palm seed particles produced from date palm seeds and scrap tire particles produced from scrap tires. The LCM may include date palm seed particles in the range of about 50 wt % to about 80% and scrap tire particles in the range of about 50 wt % to about 20 wt %. Methods of lost circulation control and manufacture of a hybrid particle mix LCM are also provided.

## Claims

### Claim 1

A lost circulation material (LCM) composition, the composition comprising:
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 1000 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 first plurality of particles comprise an amount in the range of 50% by weight to 80% by weight and the second plurality of particles comprise an amount in the range of 50% by weight to 20% by weight; and
wherein the LCM has a coefficient of resiliency of at least 0.5 and prevents the loss of whole mud in the lost circulation zone.

### Claim 2 (depends on 1)

The LCM of claim 1, consisting of the first plurality of particles produced from date tree seeds and the second plurality of particles produced from scrap tires.

### Claim 3 (depends on 1)

The LCM of claim 1, wherein the first plurality of particles comprise a first plurality of untreated particles produced from untreated date tree seeds.
