Production wells survey


Method of logging tools wireline-conveyed running in hole under the pumpp61.jpg

Survey method:
  • Surveys are carried out while the electrical centrifugal pump is running, with the use of special wellhead equipment. Outer diameter of casing strings: 146 – 168 mm.
  • The logging wire with the integrated logging tool located under the electrical centrifugal pump is tripped in together with the electric centrifugal pump. Special deflecting eccentric stabilizers divide the logging wire and power cable for electric centrifugal pump powering up into various sectors.

Advantages:
Determination of main formation operational parameters, well technical condition during operation without electric centrifugal pump pulling out of hole and of overhaul crews involvement.



SPRUT method

Software and hardware system for continuous control over operation of the electric centrifugal pump unit and producing reservoirs.

Advantage:
Determination of main formation operational parameters, well technical condition during operation in on-line mode using KRBK (oil submersion armoured round) cable without electric centrifugal pump pulling out of hole and overhaul crews involvement.





Survey of operating wells, equipped with rod well pumps

p63.jpg

Survey method:
Surveys are carried out in an operating well by running in hole an integrated logging tool conveyed with a special logging wire in the annulus through a special hole in the tubing head adapter at the string flange.

Advantages:
Allows for surveying directional wells with inclination angles exceeding 50 degrees. Determination of main formation and process equipment operational parameters and well technical condition in an operating mode.

Tasks solved:
  • Determination of fluid-movement profile.
  • Compositional analysis of fluid coming into the well.
  • Behind-casing fluid movement detecting.
  • Well flow test.
  • Oil-water ratio determination.
  • Tubing shoe, pump, water-oil interface and dynamic level location identification.
  • Tubing, casing, bottomhole integrity verification.

Survey of injection wells by wireline autonomous logging tools and slickline logging tools with the use of ULGIS-21-60 lubricator.

ULGIS-21-60 lubricator is designed for sealing a 5-7 mm logging wireline in the process of tripping and pulling 4 m long and 42 mm wide logging bottomhole tool while logging in operating oil producing and injection wells with wellhead equipment at wellhead pressure of up to 21 MPa. It is transported in a logging truck, mounted manually by 2 persons on wellhead equipment within 30 minutes and enables works performance without a derrick (mast or crane).

This method allows for reaching the performance targets without bleeding the well, complying with environmental requirements due to better wellhead sealing.

  • Well injectivity survey.
  • Tracking the injected liquid outflow profile.
  • Pressure testing of the string sealing below the tubing shoe and packer.
  • Pressure testing of the tubing by measurements using a set of methods: high-sensitivity temperature logging, indication downhole flowmeter, pressure gauge.

Assessment of formations saturation through the string

To assess formations oil saturation at a late stage of fields development, log survey is performed with impulse neutron-neutron logging.
To assess formations oil saturation at a late stage of fields development, log survey is performed with CO-logging.

New methods for behind-the-casing flows determination

Active thermal metering method for the well condition diagnostics

Essence of the method:
  • reaction of the metal well casing string and borehole environment to short local induction impact;
  • determination of main trends in change of temperature field, magnitude, speed and direction of thermal mark movement.

Tasks solved:
Active thermal metering method is an excellent supplement to conventional thermal metering, ensuring efficient solution of tasks associated with formation and well diagnostics including difficult cases.
  •  Determination of behind-the-casing flows from the top.
  •  Determination of behind-the-casing flows from the bottom in case of short sumps.
  •  Identification of inflows in marginal wells.
  •  Assessment of the flow rate in marginal wells.
Determination of behind-the-casing flow with active thermal metering

Conventional thermal metering:

Features: flows mixing in bed top and bed floor, change of the temperature gradient in the cross-flow interval due to heat exchange of counteflows, abnormal temperature in the sump.

Active thermal metering

Features: heat distribution from the heated section and thermal marks movement direction.
