EAGE Presentation

Rob Lander and Linda Bonnell from Geocosm gave an invited presentation at the EAGE in Copenhagen regarding the state-of-the-art in reservoir quality prediction methods on June 11, 2018. Summary:Sandstone reservoir quality prediction has moved from a reliance on simple empirical trends (e.g., porosity vs. depth) to include process-oriented forward models. Process-oriented models are more accurate…

Reservoir Quality and Burial Model Evaluation By Kinetic Quartz And Illite Cementation Modeling: Case Study of Rotliegendes, North Germany

This article published in the AAPG Bulletin represents part of Benjamin Busch’s Ph.D. dissertation and includes Geocosm’s Linda Bonnell and Rob Lander as co-authors. Silicate reaction kinetics provide a complementary means to other established paleothermal indicators such as organic maturation for evaluating thermal reconstructions. In this study we combine the use of an organic maturation…

Clastic Reservoir Quality Prediction Models: Past, Present, and Future

In this invited talk at the Annual AAPG Meeting, Geocosm’s Rob Lander and Linda Bonnell review the history and current state-of-the-art in reservoir quality prediction models while also discussing potential future developments. Over the past 20 years reservoir quality assessment has expanded from a focus on description to encompass process-oriented models. These models predict rock…

Controls on Reservoir Quality in Exhumed Basins: An Example from the Ordovician Sandstone, Illizi Basin, Algeria

This paper published in Marine and Petroleum Geology represents part of Kara English’s Ph.D. dissertation and involves the application of Geocosm’s Touchstone and T>Map simulation systems. Geocosm’s Rob Lander and Linda Bonnell are co-authors.  The animation below shows the T>Map simulation discussed in the paper. https://www.geocosm.net/wp-content/uploads/2019/02/TMap-Illizi-Basin-perm-animation-20fps1.mp4 Petroleum exploration in many North African intracratonic basins targets Early Paleozoic sandstones as the primary reservoir objective. These sandstones…

Reservoir Quality and Rock Properties Modeling – Triassic and Jurassic Sandstones, Greater Shearwater Area, UK Central North Sea

This paper by geoscientists from Shell as well as Geocosm’s Linda Bonnell shows how Geocosm’s Touchstone system for reservoir quality prediction can be linked to rock physics models. It also documents successful pre-drill predictions made using this approach. The complex burial and diagenetic histories of the Jurassic Fulmar and Triassic Skagerrak sandstones in the UK…
