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 […]

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/6vvd53W5jWE whitson+ – comprehensive software updates list The updated manual can be found here: https://manual.whitson.com/. I would also like to take the opportunity to thank […]

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 […]

Rate Transient Analysis (RTA) of Fracture Swarm Fractal Networks

Rate Transient Analysis (RTA) of Fracture Swarm Fractal Networks

This week we wanted to highlight and share a paper we think everyone in tight unconventionals should read, namely URTeC 2118, “Rate Transient Analysis of Fracture Swarm Fractal Networks” by Jorge Acuna. The paper is a few years old now, exemplifies how RTA can be formed on wells with complex fracture networks. Fractal techniques are […]

Sampling a Stimulated Rock Volume: An Eagle Ford Example

We wanted to highlight and share a paper we think everyone in tight unconventionals should read, namely URTeC 2670034, “Sampling a Stimulated Rock Volume: An Eagle Ford Example” by Kevin Raterman and Helen Farrell et al. The paper is a few years old now, but has fundamentally changed the mental model for how unconventional rocks […]

Chow pressure group (CPG) for different wells

Quantifying Pressure Interference in Horizontal Shale Wells

We wanted to highlight and share a paper we think everyone in tight unconventionals should read, namely SPE-191407-PA, “A New Technique for Quantifying Pressure Interference in Fractured Horizontal Shale Wells” by Weichun Chu, Kyle Scott, Ray Flumerfelt, Michael Zuber and Chih-Cheng Chen. The paper is a few years old now, but has become the “go-to” […]

Converting RTA Half-Lengths to Actual Non-Uniform SRV Half-Lengths

We wanted to highlight and share a paper we think everyone in tight unconventionals should read, namely URTeC 3719890, “Closing the Gap in Quantifying the Extension of Depletion: A Practical Workflow to Convert Analytical Fracture Half-Length to Actual Non-Uniform SRV” by Vivek Muralidharan and Soodabeh Esmaili. The paper addresses an important challenge in leveraging RTA […]
