RTA – Using all the Tools in the Toolbox

By: Mathias Carlsen I’m personally a fan of using all the “tools in the toolbox” when analyzing well performance. In whitson+, that includes, They should all tell a story. And a consistent analysis would tell a consistent story. BUT each method has its own strengths, weaknesses, and assumptions. And those are important to understand. In […]

Caution: whitson+ release is coming in hot ☕

We’re happy to share the latest release of whitson+, fresh out of the coding oven. There is a lot of new functionality in this release, and we’ve highlighted the main ones in this video: https://youtu.be/EbYVxNOVcyY  The updated manual can be found here: https://manual.whitson.com/.  I would also like to take the opportunity to thank you all for the great […]

What makes my fluid different from your fluid?

Author: Markus Hays Nielsen In order to describe the behavior of petroleum fluids, an accurate and consistent fluid model is needed. Different fluid systems can behave significantly differently during depletion of the reservoir and throughout the downstream system. The aim of the following articles is to describe what makes different fluids behave differently and how […]

User Guide to the Gamma Distribution Model

Author: Markus Hays Nielsen The most critical part of making a fluid model for petroleum mixtures is the C7+ characterization. We will be publishing a set of articles on this topic where we go through all the nitty-gritty, but for now we just wanted to get in the mood by becoming more familiar with the […]

Powder River Basin – Multi-Client PVT Study

Last updated: 24 January 2023 Powder River Basin – Multi-Client Study The Powder River Basin (PRB) multi-client project was first initiated in 2022. The main objective of the study was to create one, field-wide equation of state (EOS) model for the entire PRB. Since then, more data has been incorporated into the model, resulting in […]

Mud gas to predict PVT

Shale PVT Estimation Based on Readily Available Field Data

This week we wanted to highlight and share a paper we think everyone in tight unconventionals should read, namely URTEC-1884129-MS, “Shale PVT Estimation Based on Readily Available Field Data” by Tao Yang et al. The paper is a few years old now, but is a “go-to” paper on using mud gas for PVT predictions. Accurate […]

Numerical RTA

Numerically Enhanced RTA Workflow

This week we wanted to highlight and share a paper we think everyone in tight unconventionals should read, namely URTeC 2967, “Numerically Enhanced RTA Workflow – Improving Estimation of Both Linear Flow Parameter And Hydrocarbons In Place” by Braden Bowie and James Ewert. The paper is a few years old now, but is one our […]
