Kazakhstan hosts three of the world's largest oil and gas fields: Tengiz (supergiant onshore, 26 billion barrels OOIP), Kashagan (offshore Caspian, 38 billion barrels OOIP), and Karachaganak (gas condensate). These fields present extreme drilling challenges — depths of 4,500–5,500 m, bottom-hole temperatures of 110–150°C, high H₂S concentrations, and abnormal pore pressures — that require HTHP-rated organoclay in OBM and SBM formulations. CP Organoclay supplies HTHP grades to Kazakh drilling contractors via overland rail, the fastest logistics route between China and Kazakhstan.
Organoclay Applications in Kazakhstan
| Field / Application | Conditions | Recommended Grade | Dosage |
|---|
| Tengiz — OBM viscosifier | BHT 110–140°C, 5,000–5,500 m depth | CP-34, CP-EL | 8–15 kg/m³ |
| Kashagan — HTHP SBM | BHT 108–125°C, high H₂S (up to 26%) | CP-EL, CP-GL | 10–18 kg/m³ |
| Karachaganak — gas condensate | BHT 120–150°C, 4,500–5,200 m | CP-EL | 10–18 kg/m³ |
| Conventional Kazakhstan wells | BHT <120°C, standard OBM | CP-34, CP-40 | 5–12 kg/m³ |
| Paint & Coatings (Almaty) | Industrial coatings market | CP-34, CP-APA | 0.3–1.2 wt% |
Key Takeaway: Kashagan OBM design must account for extremely high H₂S (up to 26 mol%) in the reservoir gas. CP-EL organoclay provides stable rheology in SBM formulations at 120°C / 500 bar HTHP conditions, with no degradation observed in H₂S-saturated fluid environments — validated in laboratory HTHP aging tests at 120°C × 16 hours under 10% H₂S atmosphere.
Logistics: Shipping from China to Kazakhstan

Frequently Asked Questions
Who supplies organoclay to Kazakhstan?
CP Organoclay is a direct Chinese manufacturer exporting organophilic clay to Kazakhstan since 2014. We supply Kazakh oilfield service companies for Tengiz, Kashagan, and Karachaganak drilling operations. ISO 9001:2015 certified; API 13A-tested HTHP grades available. Overland rail from China: 12–18 days to Almaty or Atyrau. Free samples by air courier: 4–6 business days.
What organoclay grades are needed for Tengiz and Kashagan drilling?
Tengiz (BHT 110–140°C): CP-34 for upper sections, CP-EL for deep HTHP intervals. Kashagan (BHT 108–125°C, high H₂S): CP-EL or CP-GL in SBM — validated stable in H₂S-saturated environments. Karachaganak (BHT 120–150°C): CP-EL at 10–18 kg/m³. For standard Kazakh wells below 120°C: CP-34 or CP-40. Contact our technical team with formation temperature, pressure, and fluid specification for a detailed recommendation.
How is organoclay shipped from China to Kazakhstan?
Fastest route: overland rail China → Khorgos or Dostyk border → Almaty or Atyrau in 12–18 days. For Caspian coastal delivery to Aktau port: sea freight Qingdao → Baku → Caspian ferry to Aktau in 20–28 days. Trans-Siberian rail via Russia is also available in 18–25 days. Air courier for samples: 4–6 business days to Almaty, Nur-Sultan, or Atyrau.
