Arctic well cementing blends CemFrost

Well cementing in permafrost conditions is a complex engineering challenge

Cementing conductor and surface casing in extremely low temperatures is complicated by unstable rock, seasonal ground thawing and difficult logistics. Process deviations may compromise isolation and casing integrity, while excessive waiting-on-cement time increases rig downtime and total well construction costs.

CemFrost gypsum cement blends are developed by Granula SpecCement Group for cementing conductor and surface casing in permafrost regions.

High-quality raw materials

CemFrost blends use high-activity alpha gypsum specially adapted for oil and gas well cementing systems.

Rapid cement stone formation

An optimized binder and hydration accelerator system reduces waiting-on-cement time and rig downtime.

High strength and integrity

Low thermal conductivity reduces heat transfer into the ground and helps prevent thawing and casing deformation. Low porosity and high casing adhesion prevent cracks and microchannels.

Durability

Mineral additives maintain structural integrity through freeze-thaw cycles. Water resistance preserves strength during prolonged contact with groundwater and formation water.

CemFrost is an investment in well profitability and safety

Reliability

Automated factory dosing eliminates human error and ensures repeatable slurry properties at every well.

Speed

Rapid early strength development at sub-zero temperatures shortens waiting-on-cement time and reduces costly rig downtime.

Efficiency

The ready-to-use all-in-one blend eliminates the costs of purchasing, storing and mixing separate additives on site.

Proven in the Arctic

01
Thousands of wells have been cemented with CemFrost blends and are successfully operating in the Yamal-Nenets region, the Yamal Peninsula, Eastern Siberia and Yakutia.
02
Acoustic cement bond logging confirmed a uniform cement sheath with high bonding indices across significant intervals.
03
The blends perform consistently from site to site: dense cement stone forms quickly, annular flow is prevented and annular pressures remain stable.
