Epeiric Marine Unconventional Reservoir Variability: Examples from the Permian of West Texas, Jurassic of West Kuwait, and Cretaceous of the Powder River Basin
URTeC Core Workshop
Sunday, 19 June 2022, 8:00 a.m.–4:00 p.m. | Houston, Texas
Who Should Attend
Geoscientists and engineers currently interested in the Midland, Delaware, and Powder River Basins of the U.S. and/or the Najmah Formation of Kuwait or relevant analogues.
Objectives
This workshop explores variability in sedimentation, stratigraphic architecture, and reservoir character in examples of core from an intracratonic sub-basin (Jurassic Kuwait), a continental seaway (Powder River Basin), and an intracratonic basin rimmed by carbonate platforms (Permian Basin). Participants will work with instructors to evaluate integrated stratigraphic, petrographic, and geochemical data and interpret the genesis of reservoir properties.
Course Content
Cores from both sediment-gravity-flow-dominated and mainly hemipelagic epeiric marine environments will be examined and compared to evaluate the variety and origin of reservoir characteristics. Supporting high-resolution XRF chemostratigraphy, XRD, TOC, RCA, thin section petrography, SEM petrography, porosity, permeability, saturations and rock mechanics data will be applied and integrated into interpretation.
Cored strata include: 1) inner, middle, and outer ramp/basinal deposits from the Najmah Formation (West Kuwait), 2) siliciclastic turbidite, debrite, and hemipelagic deposits from the Wolfcamp C (Midland Basin, Howard Co., TX), 3) carbonate-dominated sediment gravity flow and hemipelagic deposits from the Wolfcamp A/B (Delaware Basin, Winkler Co., TX), and 4) mainly hemipelagic mudrocks of variable composition and fabric from the A, B, & C intervals of the Niobrara Formation (Converse Co., WY).
Itinerary Roster
In the morning, we will begin with a short introductory presentation to provide context on the location of the core and the depositional settings within the Jurassic Najmah Formation. We will study the Najmah core in conjunction with relevant data from the cored interval and then discuss relationships between reservoir properties and depositional setting, stratigraphic architecture, sediments, diagenetic features, and fractures.
We’ll then provide a short presentation to introduce the Powder River Basin depositional system and core location, and we will work through the Powder River Basin core and accompanying datasets. This will be followed by a brief discussion of depositional setting, stratigraphic architecture, sediments, diagenesis, and reservoir properties as well as a brief comparison of the Powder River core with the Najmah core.
In the afternoon, we will begin with a short introductory presentation to provide context on the locations of the cores and depositional processes within different parts of the Permian Basin. Then we will examine the Midland Basin and Delaware Basin cores as well as the accompanying data. This will be followed by a brief discussion of depositional setting, stratigraphic architecture, sediments, diagenesis, and the impacts of these variables on reservoir properties. After viewing and discussing all four cores and their varied depositional histories and reservoir properties, we’ll conclude by comparing and contrasting these different unconventional hydrocarbon systems and highlighting some of the benefits of whole core analysis in reservoir characterization studies.
