Class G

API Class G Oil Well Cement

Class G Cement Supply in Uzbekistan

We supply API Class G Oil Well Cement for primary and remedial cementing operations in oil and gas wells.

Class G cement is one of the most widely used base cements in well cementing. It is designed to be used either as a neat cement or as a base cement for slurry systems modified with retarders, accelerators, fluid-loss additives, dispersants, extenders, weighting agents and other cementing additives depending on well conditions.

Supply can be arranged to Tashkent and other regions of Uzbekistan, as well as to other Central Asian markets.

Application in Oil & Gas Well Cementing

API Class G cement is commonly used for:

  • primary casing cementing;
  • liner cementing;
  • squeeze cementing;
  • remedial cementing;
  • plug cementing;
  • cement slurry systems for conventional and high-temperature wells;
  • lightweight or heavyweight slurry systems when combined with suitable additives;
  • gas well cementing when incorporated into properly designed gas-migration-control systems.

The final cement slurry formulation depends on well depth, BHCT/BHST, pressure, required slurry density, thickening time, fluid-loss control, rheology, compressive-strength development and other operational requirements.

Product Information

Actual chemical and physical properties depend on the selected manufacturer, production batch and applicable specification.

Class G Cement for Different Well Conditions

Class G cement can be used as the base material for a wide range of cement slurry designs.

With the appropriate additive package, slurry properties can be adjusted for:

  • low- and high-temperature wells;
  • extended thickening time;
  • accelerated setting;
  • reduced fluid loss;
  • controlled free water;
  • improved slurry rheology;
  • gas migration control;
  • lightweight cement systems;
  • heavyweight cement systems;
  • enhanced compressive-strength development.

Selection of the cement and additive package should be based on laboratory testing under simulated well conditions.
