The platform covers empirical, analytical, and numerical approaches which greatly helps when analyzing data. The whitson team is incredibly responsive in addressing issues, adding new features, and enable knowledge sharing with industry peers. They truly stand out from other “software providers” and something that every reservoir engineer should have in their toolkit.

  • Matt Padgham Citizen Energy Senior Reservoir Engineer

    The whitson team is what you want in a partnership, they have the technical know how along with a desire to build the best and most efficient platform. I am routinely blown away by their responsiveness to questions and product enhancements. A reservoir simulation study or sensitivity that took hours or days historically can now be completed with confidence in the matter of minutes. As a reservoir engineering community, we are also fortunate that whitson is committed to enhancing the overall discipline by providing training, knowledge sharing, and joint industry projects.

  • Steve Jones Consultant Recognized Reservoir Engineering Expert

    I love the PVT tools and the fact the black-oil tables work flawlessly in simulators. I’ve also found whitson to be the most responsive in implementing new technologies for reservoir analysis, while working out the fundamentals necessary to bring them to practical application.

  • Michael Tantillo Anschutz Exploration Corporation Reservoir Engineer

    whitson+ has proven to be an incredible resource. The user-friendly interface allows for quick analysis, which has allowed to us to make decisions to drive spacing and completions for future development. The customer service at Whitson is one of a kind; through training, fast response time, and continuous development to the program, my experience with whitson+ has been wonderful.

  • Matt Maguire Diamondback Energy Senior Reservoir Engineering Advisor

    whitson is an excellent company to partner with. They bring expertise across PVT, hydraulic BHP calculations, RTA, DCA, and provide a well-constructed easy to use seamlessly integrated Web based software. In addition, their response time on questions, software modifications, and overall support is blazing fast. Touching on software modifications: I have never worked with a company that is not only open to making changes to help clients but completes them quickly. Not years, not quarters, not months, but in days or weeks. Very impressive. Just a great group of folks to work with.

  • Steven Young Devon Energy Asset Supervisor

    whitson+ has been instrumental in our operations, seamlessly integrating 5000+ wells for daily updates. The real-time production and wellbore data, allowing us to calculate bottomhole pressures, have been a game-changer. The support from whitson+ is top-notch. Their team is responsive and knowledgeable, ensuring our operations run smoothly.

  • Jason Billings Civitas Resources Reservoir Engineer Advisor

    whitson is keen to improve their product with user feedback and cutting-edge technical tools. whitson+ workflows span the needs of petroleum engineers, from basic DCA on thousands of wells to full physics simulations. Feedback and questions are always encouraged, and a whitson team member will respond to your query within minutes.

Take PVT to the next level

PVT has an impact on essentially every discipline in the petroleum domain. However, utilizing and accessing PVT information can be costly, impractical and time-consuming. whitsonPVT streamlines the access to both PVT data and models throughout an organization. Every PVT report, black oil table, fluid initialization model or gas-EOR calculation is centralized in one place. We like to think about it as a living document for PVT data and models that ensures consistency and enables collaboration across an organization.

    Key Features

  • PVT laboratory quality checks (QCs)
  • C7+ Characterization & Gamma Modeling
  • EOS Tuning & Pseudoization

Our Consultancy Services

Fluid Characterization

Understanding petroleum fluids is fundamental to maximizing the profitability of oil and gas assets, as the fluids are what we produce, and what we sell. An equation of state (EOS) model is one of the most sophisticated technologies available to describe these petroleum fluids. We have over the last 30+ years specialized in EOS model development and fluid characterization. Our EOS development projects generally involve multiple fluid samples from different wells.

    Example Tasks

  • PVT Report / Data QC
  • EOS Model Development
  • Black Oil Table Generation
  • Fluid Initialization

Gas Condensate Reservoirs

whitson gas condensate services include topics related to PVT, condensate blockage, and simulation of well productivity, depletion and gas cycling using black-oil and EOS reservoir models. We work with all PVT laboratories on design, QC and interpretation of conventional and special gas condensate PVT studies. We develop EOS and black-oil PVT models with special emphasis on gas condensate issues like CGR variation, condensate blockage and gas cycling EOR. Together with Stratum Reservoir (Trondheim Lab) we quantify near-well flow leading to blockage; whitson designs and interprets the lab tests, then develops velocity-dependent relative permeability models.

    Example Tasks

  • Relative Permeability Experiment Design
  • Relative Permeability Modeling
  • Condensate Blockage Modeling
  • Gas Cycling / EOR
  • EOS & Black Oil PVT Modeling

Gas-Based EOR

Enhanced oil recovery with gas injection is a commonly used strategy to increase the recovery from existing oil and gas fields. We assist our clients in both conventional and unconventional assets in addressing the challenges related to the implementation and operation of gas EOR projects, specifically assisting in selection of wells for injection, design of injection strategy (number of wells, injection pressures & volumes), and history-matching once the EOR has been started. 

    Example Tasks

  • Design Lab Program
  • Candidate Selection & Screening
  • Gas EOR Modeling
