 CONNAS TEST WELLS

Accurately replicating downhole conditions (pressure, temperature, foaming, viscosity, gas content, etc.) is a serious problem for most oil and gas production companies. Electrical submersible pumping (ESP) systems and other downhole production solutions are often installed without any reliability testing whatsoever. This increases the likelihood of failure and can lead to significant loss of time and money.

Novomet partnered with the IM Gubkin Russian State Oil and Gas University to develop a multifunctional testing and experimentation complex inside our CONNAS Design Bureau facility in Moscow. This facility features two labs and eight test wells of various size that enable us to mimic downhole conditions and perform thorough testing before finalizing designs and beginning mass production. The CONNAS test wells and labs give us a clear advantage over all our competitors inside Russia and most international production service companies.

We currently perform tests under the following scenarios:

  • Multizone production testing—Used to assess system capability to produce simultaneously and separately from two or more production zones
  • High-gas-ratio testing—Enables pumps to be evaluated based on their ability to continue pumping as gas-to-fluid ratios increase and at pressures up to 440 psi (30 atm)
  • High-temperature testing—Used to test production equipment in temperatures up to 480°F (250°C)
  • Asphaltene and paraffin testing—Used to determine temperature and deposition rates of asphaltenes and paraffins in ESP systems and components, and to develop technologies for reducing these depositions
  • Scale testing—Used to simulate scale deposition across conditions to help us mitigate scale accumulation through the use of materials, coatings, inhibitors, and flowpaths.
  • Vibroseismic testing—Enables the study of vibroseismic effects on formation permeability, and can also be used to perform vibration testing in hydraulic motors
  • Vertical testing—Consists of four wells up to 164 ft (50 m) deep that enable ESP acceptance tests, parametric and classification tests, and determining pressure/energy/vibration limitations
  • Stage testing—Tests hydraulic and power limits and defines axial force (raising and lowering) of ESP pump stages in the vertical position
  • Rheology testing—Defines the physicochemical properties of formation fluids (including fluid stability and foam properties) and simulates salt, paraffin, and asphaltene deposition under controlled thermobarocyclic conditions
  • Laser prototyping—Produces three-dimensional components from metal powder through the use of laser sintering technology
