Well testing

Conducting well testing is essential preparatory work when planning the development of oil and gas fields. The main purpose is to obtain -geological and production data for reserves calculation, to choose a crude development method and prove its economic feasibility based on the data.

Our approach

Together with conventional research, SIAM Company actively develops new integrated approaches, which combine performing conventional research and applying technologies of oil, gas and gas condensate production.
Taking into account the depletion of main oil and gas fields as well as diminishing reserves and their quality deterioration, remote fields are being actively explored and developed nowadays. The most effective way to study oil field potential at early stages of development is pilot oil production with the possibility to process hydrocarbons to market standard

This kind of service is performed with mobile well testing labs MWTL SIAM. They allow a subsoil user to cope with the following tasks:

  • confirmation of geological and recoverable reserves;
  • prompt assessment of a production target;
  • drilling optimization program;
  • mitigation of infrastructure development investment risks;
  • optimization and operational management of CAPEX, OPEX;
  • advanced re-engineering of surface facilities.

Integrated approaches

Purpose and advantages:

  • long-term well testing and early production under tax benefits;
  • production rate measurements in a wide range;
  • processing the production (including market standard) and its shipment to subsoil users;
  • operating at remote fields in full autonomy.

Benefits for subsoil user:

  • gathering full information about a geological object with minimum cost;
  • prompt assessment of a geological object;
  • cost saving by twice on surface facilities under conditions of uncertain oil / gas in place and capacity of field to produce;
  • optimization of current oil production and development;

Flexible approach to providing equipment can reduce time of bringing into service to 2-4 months depending on the real Customer’s needs.
