A renewable, biodegradable alternative to synthetic & mineral lost circulation materials — engineered for the well, grown in the field.
Laboratory-verified sealing up to 1,000 psi — independent third-party test per IPS-G-DR-915. Field-applied by Drilling Company Samara at Samaraneftegaz wells, sealing losses of up to 3 m³/h.
Suitable for zero-discharge operations and environmentally sensitive wells with strict HSE requirements — a plant-based material that breaks down naturally.
Produced from thermally processed and calibrated sunflower husk — a renewable, plant-based raw material, not a mined or petrochemical feedstock.
Sealing performance up to 1,000 psi, verified in an independent laboratory per IPS-G-DR-915. Full test report available on request.
Compatible with WBM / OBM / SBM drilling-fluid systems across a broad range of applications.
Blends and particle-size fractions tailored to your well program and specification.
The KL series is graded by particle size, and each grade answers a different severity of loss — from seepage and filtration control to total losses. Grade designations match our Technical Data Sheet exactly.

The finest grade — for seepage losses and filtration control in the mud system.

The workhorse grade, supplied as 0 – 1 mm or 0 – 2 mm. Sieve analysis published below.

Fibrous mid-range grade for bridging partial-loss zones.

Coarse grade for severe losses and wider fractures.
The coarsest grade in the series, produced to order for severe and total losses.
Typical values for serial production of the KL series. Parameters for a specific batch are confirmed by the quality passport issued for that batch.

Applied by Drilling Company Samara at Samaraneftegaz wells — fractions from 200 to 1,250 microns, in rotary drilling and with downhole motors, sealing losses of up to 3 m³/h. Reported as inert to the mud system, with no caking.
A concise, honest comparison of common lost-circulation material types.
