This talk will Illustrate how porosity and permeability can be measured and predicted at the core scale, then upscaled to log and reservoir scales. Statistical tests and corrections of log means will be discussed to show how standard workflows to predict permeability from core data can often underestimate well-scale dynamic flow characteristics if such corrections are not made
You'll learn
-
Core permeability fundamentals
-
Common upscaling workflows
-
Where traditional methods fall short
-
Improving reservoir-scale KH predictions
-
Impact on well productivity forecasting
-
Practical case studies

Profile
Jonathan is a Petrophysicist with over thirty years of oil and gas industry experience. The last eighteen were spent at Hess Corporation where most recently he led Subsurface Operations for the Exploration and Offshore business units in Houston, focusing on deepwater offshore drilling operations with specialization in Geohazards/PPFG, Wellsite and Operations Geology and Formation Evaluation, while maintaining key Petrophysics skillsets via continuous technical exposure, leading interpretation studies for key exploration, appraisal and development wells in the UK, Europe, Africa, Middle East, South-East Asia, North America and Guyana/Suriname reservoirs. He has also been employed in Petrophysicist and Petroleum Engineering roles by BHPB, PGS and Enterprise Oil. He has extensive familiarity with both clastic and carbonate reservoir petrophysical interpretation, open and cased hole evaluation and integration with static and dynamic reservoir modelling in both conventional and unconventional (tight oil and shale gas) reservoirs.
