Sendra is a two-phase core flooding simulator specially designed to simulate and verify SCAL experiments. It covers all common experimental approaches, including unsteady-state and steady-state flow experiments, single- and multi-speed centrifuge experiments, as well as porous plate experiments. It can be utilized for oil-water experiments as well as gas-oil or gas-water experiments, for both imbibition and drainage processes.
The main application of Sendra is to determine relative permeability and/or capillary pressure from experimental data through an automated history matching approach. Sendra can simulate all common SCAL experiments and can be used as a tool for planning and successful execution of your SCAL projects.
Sendra is tailored for SCAL and it includes options necessary for laboratory application. The core geometry and physical properties are easy to handle. Sendra is not constrained by limiting assumptions, such as zero capillary pressure – which analytical methods are. Consequently, Sendra provides for an excellent means of quality control of analytical methods. Even though Sendra is an advanced and flexible simulation tool within special core analysis, the user friendliness is maintained through a well-arranged user interface.

Sendra celebrated its 20 years in the industry in 2012 as it was first commercially released back in 1992.
Sendra was initiated at IRIS (former RF-Rogaland Research). The product development was performed in close cooperation with Texas A&M University (USA), the University of Bergen (Norway) and the oil industry. This cooperation integrated knowledge and expertise from all into one product. Further, a lot of our customers have compared the output from Sendra with their own in-house software as well as with reservoir simulators.
A good number of Sendra-related papers have been accepted at international conferences and in publications; the development of Sendra, numerical SCAL studies by use of Sendra and the use of experimental SCAL data to be processed with Sendra.
