Mud Gas Isotope Analyses: Low Cost & High Impact

Posted by GeoMark Technical Team on Jun 10, 2020 5:13:16 PM

In the current oil and gas environment seeking subsurface understanding and constraint can be limited due to capital pullback. The most important thing to remember is that there are a number of scientific tools that can constrain uncertainty and help...

Application of Triple Quad GC-MS/MS (QQQ) to Enhance Understanding of Petroleum Systems

Posted by Craig D. Barrie; Catherine M. Donohue; J. Alex Zumberge; Don Rocher on Jun 10, 2020 10:30:31 AM

Introduction For decades, the bulk of geochemical characterization and source discrimination of produced oils has relied upon analysis of traditional biomarkers via Gas Chromatography (GC) and Gas Chromatography - Mass Spectrometry (GC-MS). There is...

Linking Geological to Petrophysical Attributes: To Lump or Not to Lump

Posted by Dr. Stephanie Perry on Apr 28, 2020 1:27:34 PM

The Delaware Basin of the greater Permian system in West Texas is a complex setting with varying stratigraphic patterns. The key to the Delaware Basin is understanding deep resistivity and sonic log responses, as it presents a simple way to different...

Extracting Hydrocarbons from Core - Methods to Maximize Sample Integrity

Posted by GeoMark Technical Team on Mar 27, 2020 12:12:30 PM

Introduction In this Science Bulletin, we investigate light-end hydrocarbon (LHC) preservation in core samples using various solvent extraction techniques. Traditional solvent extraction methods are overly exhaustive and destructive towards LHCs maki...

Production Allocation in Reservoir Geochemistry - Understanding Heterogeneity

Posted by GeoMark Technical Team on Mar 27, 2020 12:10:05 PM

Introduction Recent geochemical studies of unconventional fields have focused on production allocation; a method already perfected in conventional systems with homogeneous ‘end-members’ for production compartments. Using these ‘end-members’ (geochemi...

Maximizing Production with Reservoir Geochemistry & Produced Fluid Monitoring

Posted by Craig Barrie on Mar 16, 2020 11:04:27 AM

The operator race to transition to full co-development in the Delaware basin is in full force heading into 2020, while other unconventional plays in L48 and International assets continue to be explored, exploited and co-developed. Decision makers and...
