Kapexy’s experience covers PVT modeling of all types of petroleum reservoir fluids. Below are examples of the fluid modeling services offered.

On-Site EoS Modeling

I offer to conduct on-site Equation of State (EoS) modeling anywhere in the world at a short notice. With 30+ years of experience, you are guaranteed a qualified product. The EoS modeling service can optionally be combined with training of your engineers in the EoS modeling discipline to enable them to solve EoS modeling tasks in the future.

EoS Modeling with Limited PVT Data

Despite a substantial development of PVT simulation techniques, the routine PVT data measured by commercial PVT laboratories has remained almost unchanged for the past 50 years. I offer based on a fluid composition and the saturation pressure at the reservoir temperature to generate a full PVT report of almost the same accuracy as can be obtained in the laboratory. This is done using a technique that involves prediction of the mixture critical point. I will be happy to document this technique on fluids for which you have a full PVT study. Send me the reservoir fluid composition and the saturation pressure at the reservoir temperature and I will free of charge generate a full PVT report, which you can compare with the one from the PVT laboratory.

Getting to Understand a PVT report

The biggest hurdle when developing an equation of state model for a reservoir fluid is not always the EoS modeling itself, but figuring out which fluid compositions and PVT data to enter in the PVT simulation program. Today’s PVT reports are very comprehensive, and not all data is relevant in the EoS modeling. I offer courses in interpreting PVT reports and explaining what is relevant in EoS model development. The client may send PVT reports in advance that are relevant to the course participants. During a subsequent 1-2-day course, I will outline which data to input into a PVT simulator to have the right basis for a subsequent PVT modeling.

Thermodynamics for Reservoir Engineers

Many will remember thermodynamics at college as an endless list of equations and symbols without much connection to the real world.
I offer tailor-made courses in thermodynamics that with a minimum use of equations explain PVT concepts:

  • What determines the saturation point of a reservoir fluid?
  • Why cubic equations are unmatched
  • What makes the fluid composition in a reservoir change with depth?
  • What makes CO2 special?
  • How to explain entropy
  • What determines the variation in temperature from bottom to top of well?
  • How can the fluid type change from gas to oil in a reservoir with no GOC?

Each course is planned in a close dialogue with the client.

Guest Lecturer

You are welcome to contact me if your petroleum engineering department needs someone to teach PVT. I have more than 30 years of experience in conducting courses in PVT modeling. I will spice up the course with examples from projects carried out for the oil industry. I offer this service worldwide and the courses can last from a single day to an entire semester.
