Speaker: Dr. James W. Granath | Consulting Structural Geologist

Dr. James W. Granath is a consulting structural geologist based in Denver, Colorado, who has worked in academia and industry.  Since 1976 he has taught at SUNY Stony Brook and spent 18 years with Conoco Inc. in research, international exploration, and new ventures.  In 1999 he opened a consulting practice focused on structural geology and tectonics as applied to exploration problems, interrupted only by brief periods of exclusivity with Forest Oil and Midland Valley Exploration in Denver.   He is a member of AAPG, GSA, AGU, and RMAG, and is a certified petroleum geologist (#5512).  He is the author of numerous research papers and co-edited several multi-author compendia.  His expertise lies in seismic interpretation and integration with structural analysis, fracture analysis, regional synthesis, and prospect and play evaluation.   Jim has worked on projects in some 40 countries around the world. Recent notable projects have included the Karoo rifts in Africa, the Kurdistan, Chiapas, and Oaxaca fold & thrust belts, and the Colorado Rockies. He holds his PhD from Monash University in Australia, and a BS and MS from of University of Illinois at Champaign-Urbana. 


The Story of the Kavango Basin, An Unusual Play Emerging in Namibia

on behalf of a committee of ReconAfrica scientists and Bill Dickson, DigsGeo.com


In recent months, the project pursued in Pet Expl License 73 in northeastern Namibia by ReconAfrica has, somewhat surprisingly to me, become very high profile for various reasons.  The project has its root in recognition since about 2015 that the eastern end of the Owambo Basin actually has a younger, Karoo-aged history and has therefore been distinguished as a as a deeper dimension to the shallow Neogene “Kavango Basin.”  Secondly the project had operational limitations because of the blue-sky nature of the project, such that the operations that have been going on in 2021 were not the usual prospect-targeted operations.  Stratigraphic wells were drilled to prove up the play concepts, and now seismic acquisition is following that proof-of concept stage of the program.  The two wells were wildly successful in proving that a petroleum system is active in this part of the region, further distinguishing Kavango from the disappointing Owambo to the west.  But they did prove that my early structural models grossly exaggerate the Karoo fill in the basin.  It looks like the program has drilled into pre-Karoo high blocks that contain pieces of the much older Damara fold belt.  The Karoo extension seems to have been superimposed on that older structure and dropped it down to levels at or below sea level, a subsidence compared to surface expression of the fold belt that amounts to 1.5 km or more.  The project employed some innovative techniques in terms of responsible drilling techniques, and a low-impact seismic acquisition program. 

This talk will be in two parts, the first discussing the results of PEL 73 operations insofar as they can be released at the time of the meeting, followed by a Q and A.  There will be a short break, followed by the second part, which will delve into the tectonics behind how the play concept was developed, and some geology of this part of Africa.  The scientific significance of that work relates to how to approach an extension province from the point of view of the kinematics of the blocks involved: a displacement field approach to extension and inversion in an array of clocks rather than a fault-plane dynamics approach. 



Featured Sponsor

At SeisWare, we create user-driven software for geologic and seismic interpretation. We’re Houston locals, we’re geoscientists and as the industry pushes forward and innovates, we are too, with exceptional software and extraordinary customer care.

Our geologic interpretation software, Geology by SeisWare, is an all-inclusive package for one low-cost annual subscription. It places traditional geologic interpretation tools, including tops picking and log correlation, into a dynamic 3D environment. There is much more to our software that will make your work easier.
