OSNO-SCREEN lost circulation control technology

Description

Description: a composition based on polymer material and modifying additives.

Application: in oil extracting industry in drilling processes and well workover, in technologies of drilling fluid lost circulation control, in a wide range of lost circulation scales. The functional principle of OSNO-SCREEN is based on ability of the chemical agent to form a non-flowing composition in contact with formation water, which can effectively block the drilling fluid lost circulation zone.

Recommended discharge: it is used in pure form or diluted in a ratio of 1:1 with diesel fuel, that significantly reduces the viscosity and increases chemical agent setting time.

• Simple adjustment of setting time.
• Easy preparation of the working solution.
• Ability to change the viscosity of the base working composition.
• The absence of thickening in contact with the oil.
• Compatible with most types of water-based drilling fluids.
• OSNO-SCREEN chemical agent hydrates in contact with water, in which case the viscosity is significantly increasing through a plugging pill.
• In case of contact with formation mineralized water additional cross-linking of the polymer with polyvalent cations occurs, that significantly strengthens the structure of the resulting product.
