Well development

Borets performs the following operations using gas injection systems:

• Development of wells with the depth up to 4500 m after drilling and workover including the use of coiled tubing system
• Pressure test of pipelines by inert gas
• Pressure test of casing by the decrease of fluid level in well or by pressure
• Provision of geophysical survey, hydrodynamic exploration
• Foam-acid treatment of producing formation including removal of reaction products
•  Bottomhole flushing with gas-liquid mixture which density is 0,5 to 1,0 g/cm³

 The system is eqipped with booster chamber that enables injection of foam-gas-liqid mixture tj the depth of 4500 m. Foam-gas-liquid mixture is made up of gas, oxygen and process liquid

Well testing

Borets offers services on testing and exploration of exploratory, production oil and gas wells.
Tests are conducted in flowing wells and also by means of ESP systems of different type sizes and downhole pressure/temperature sensors compatible with ESPs.
Elimination of hydrodynamic influence of fluid located in the annular space as well as maximal differential pressure in the system formation-wellhead is provided by packer.
Well testing is made up of the following procedures:

• Determine hydro-dynamic performances of formation
  • Testing of stable producing well (trial pumping method);
  • Testing of unstable well (monitoring level or curve of pressure recovery)
•  Well production at different operating conditions;
• Content and features of formation fluid;
• Subsurface and surface sampling for laboratory analysis and etc.

The main objective for the research of reserves and wells is to obtain information required to determine potential volumes of oil and gas, design, analyze, clarify formation parameters and regulate the development, operation and optimization of operating conditions in well.
