ODSI is a subsurface consulting company offering a solution for every well and reservoir type, onshore or offshore, conventional or unconventional. Our objective is to remove the guesswork and uncertainty  helping oil and gas operators around the world make better decisions about their assets using pressure and rate data captured at the wells.

Valid flowrates and bottomhole pressures are the starting point of a reliable reservoir analysis.

Our breakthrough Well AnalyzerTM  technology takes a leap away from correlations and models and solves the Mechanical Energy Balance, accounting for friction, PVT and heat loading. This process takes the “wellbore out of the way” giving valid bottomhole pressures. For the first time in the industry, our software uses the measured pressure drop in the wellbore to calculate 1/2/3-phase oil, gas and water flowrates within 1% accuracy. The rest is easy.
