CO2 EOR Consulting

N2 EOR Consulting

Hydrocarbon gas EOR Consulting


Avasthi Consulting is the oil field CO2 EOR consulting company!

Several of our high-level and seasoned consultants have been involved in CO2 EOR project design, evaluation and optimization since the seventies,  and during this time have worked on some of the major CO2 EOR projects in the Permian Basin in West Texas. With our consultants' extensive experience working on all aspects of CO2 EOR projects, we can truly be called the CO2 EOR consulting company!

In addition to CO2 injection projects, our consultants have extensive experience working on Nitrogen (N2) injection, as well as hydrocarbon gas injection, projects:

  • Many times when we determine that CO2 injection would be an ideal EOR scheme for one of our clients' oil reservoir(s), but the client does not have the necessary CO2 supply available for injection, the client would normally ask us to evaluate the potential of injecting N2 vis-a-vis CO2. Our EOR consultants are experts in conducting N2 injection studies, as they are experts in conducting CO2 injection studies, using state-of-the-art PVT/ compositional reservoir simulation.
  • Whevever our clients discover a retrograte gas-condensate or a volatile oil reservoir, first thing they want us to do is to investigate the desirability of operating the reservoir under a reservoir pressure maintenance scheme, to keep the reservoir pressure above the saturation pressure of the reservoir fluid (presssure maintenance). In case of rich retograde gas-condensate reservoirs and high-shrinkage volatile oil reservoirs, in order to maximize liquid hydrocarbon recovery, it is esssential that the reservoir pressure be kept above the saturation pressure of the reservoir fluid (presssure maintenance), and most commonly it is done by N2 or  hydrocarbon gas injection, whichever is available and is cheaper. Our IOR consultants are experts in conducting N2 injection, as well as hydrocarbon gas injection, studies, using state-of-the-art PVT/ compositional reservoir simulation.

Our high-level and seasoned CO2 EOR consultants have not only worked on all aspects of CO2 EOR projects for more than thirty years but have also provided training to professional and managerial staff of our client companies, around the world, for many years, on ‘Practical Engineering Aspects of CO2 Injection for EOR, and CO2 Geosequestration’. An outline of this customized training workshop, that can be conducted at our clients’ offices, around the world, whenever mutually convenient, is available on request

Our high-level and seasoned CO2 EOR consultants, along with other CO2 EOR industry veterans, have also been volunteering their time and effort to train next generation of engineers in CO2 EOR technologies and practices by teaching two public courses, under the auspices of the Society of Petroleum Engineers (SPE):

Over the last eight years, more than 400 members of the SPE, from around the world, have attended these two popular courses conducted by the SPE.

We can put teams of our high-level and seasoned CO2 EOR consultants, with extensive experience in conducting reservoir engineering and simulation, facilities engineering, and related studies, for designing, evaluating and optimizing, to work on our clients’ CO2 EOR projects, around the world, whenever required.
