A lost circulation material (LCM) that includes whole date palm seeds. The whole date palm seeds LCM includes date palm seeds having lengths greater than 22.6 millimeters (mm), date palm seeds having lengths in the range of 16 mm to 22.6 mm, and date palm seeds having lengths in the range of 1 mm to less than 16 mm. Method of manufacturing the whole date palm seeds LCM include washing and drying whole date palm seeds, such that the drying includes air-drying, hot rolling, and cooling. Methods of reducing lost circulation are also provided.

Composition and method of manufacturing of whole date palm seed lost circulation material (LCM)

A method and drilling fluid additive for reducing severe fluid losses in a well, comprising a combination of granular scrap tire particles and polymer adhesive molded into a capsule shape. Once in the severe loss zone, a plurality of LCMs wedge into the formation fractures and seal off the severe loss zone.

Method and material for isolating a severe loss zone

A method and drilling fluid additive for reducing severe fluid losses in a well, comprising a combination of granular scrap tire particles and polymer adhesive molded into a spherical shape. Once in the severe loss zone, a plurality of LCMs wedge into the formation fractures and seal off the severe loss zone.

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.

Hybrid particle mix for seal and plug quality enhancement

A portable resilience testing apparatus for lost circulation materials (LCMs) is provided. The portable resilience testing apparatus includes a test cell and a probe that moves and applies a force to a sample of LCM contained in the test cell. The portable resilience testing apparatus may be used to perform a compression cycle and decompression cycle on the LCM sample. A coefficient of resilience of the LCM sample is determined from the desorbed strain energy released during the decompression and the absorbed strain energy stored during the compression cycle. A method of determining the coefficient of resilience is also provided.
