VI. On-land testing of equipment.

On-land equipment of Halliburton allows to safely control the behaviour of the well during testing . It can be used for processing of the well’s product for the purpose of getting all the necessary information and for following storage and utilization of the received effluents. There can be various models of equipment assembly for the purpose of well testing in accordance with the individual requirements and for various intra-well conditions. All equipment either meets or excels the industrial safety and quality standards.

DST/STE equipment for well testing.

DST/STE equipment is used for testing aimed at the estimation of well’s long-term potential. The alternative methods of well exploratory (logging, coring, etc) do not enable to get the necessary scope of information. With the help of DST equipment it is possible to perform well completion according to the time scheme for sampling and getting main information in respect of the pressure. STE equipment allows to test the well in various extraction regimes:

-         estimation of gas, liquids and solids produced by the well

-         registration of pressure and temperature

-         sampling of collector fluid

-         safe utilization of oil and gas flowing to the well

DST equipment includes safety, circulation and testing valves, packers, jar and face transducers of pressure and temperature. The drill-stem tester with the minimum inner drift of 1.9 (RTTS packer 65/8) is designed for operation by the maximum pressure of 1000 Ам 15000 si) and temperature of 210˚C (410˚F).

                      STE equipment includes safety valves, connections, manifold, heater, separator, burners. The efficiency of the oil burner is 99.993%. The on-land equipment comprises of an automated system of data collecting and processing SCAN2. SCAN2 is used for collecting, transmitting and analyzing of well data in the real time regime. The system allows simultaneous receipt of the information on the following parameters:

-     pressure and temperature at the well mouth

-         pressure in the casing

-         pressure and temperature in the separator

-         expenditure of oil, gas and water

The equipment was attested according to API standards and was used in the regions of vulnerable ecology where extremely strict requirements in respect of ensuring the environmental safety are applied, among them – the USA, Norway, Great Britain, etc. The usage of electronic downhole pressure gauges and thermometers produced by GRC allows to receive the most precise data during testing  and to process them with the help of a specialized software.
