RS Systems´ equipments are being used by Oil Companies, Research Institutions and Service Laboratories globally to provide vital data for the interpretation and estimation of;

  • Hydrocarbons In-Place (OIIP & GIIP)
  • Production profile and total reserves from traditional displacement mechanisms
  • Production profile from advanced displacement mechanisms (Improved Oil Recovery, IOR)

How does RS Systems products contribute in the value chain?

As an illustration of the value creation, and RS Systems products contribution, we use the Ekofisk development:

The above NPD illustration shows the originally estimated, and the updated production profiles for Ekofisk, a Norwegian chalk field in the Southern North Sea. Initially, the intention was to produce oil by primary depletion, since it was believed that pressure maintenance by water injection would harm the displacement process. Hence, the initially estimated recovery factor for the field was very low. As a consequence, extensive laboratory tests were carried out to study the effect of water injection as a displacement mechanism. These tests concluded that water injection would greatly enhance production. As can be seen water injection was initiated in the mid 80s, and this has significantly improved the recovery from the field.
