Isotopic Insights Into Water Of Condensation, Cross-Formation Water Flow, And Natural Hydrocarbon Migration In Sedimentary Basins

TRRP Training: 2022 Program

presented by: GSI Environmetal Inc.

Texas Risk Reduction Program regulations (TRRP; 30 TAC 350) establish consistent risk-based protocols for assessment and response to soil, groundwater, or surface water impacts associated with environmental releases of regulated wastes or substances.

Presented by GSI Environmental Inc., this popular and informative training series is a must for professionals who need a working understanding of TRRP and those needing to stay up-to-date with the latest TCEQ TRRP guidance and policies.

TRRP Training Course (2 Days): Provides an overview of the TRRP framework and step-by-step training on property assessment and response action procedures established under the TRRP rule

Attendees will become acquainted with rules, key guidance and policies covering affected property assessments, protective concentration levels, and response actions. The course material presents strategies for efficient project management in compliance with TRRP and explains the various report forms adopted by TCEQ.

Abstract This dissertation applies geochemical tools to track the movement, transformation, and behavior of water and gases in hydrocarbon-bearing sedimentary basins. During petroleum exploration and production, hydrocarbons are generated at the surface along with other fluids naturally present in the formation, such as formation water. In addition, where hydraulic fracturing is used to stimulate shale gas and oil production, a percentage of the injected fracturing fluid also returns to the surface. Understanding the origin and movement of these water sources, as well as targeted and non-targeted hydrocarbon gases is critical to evaluating reservoir performance and properly managing fluids at the surface. However, tracking fluid migration in deep sedimentary basins is not a simple task, as it can be significantly affected by geologic, chemical, microbial, and anthropogenic processes. This dissertation provides a framework for evaluating three types of fluid occurrence or movement that can affect our interpretation of fluid origin during hydrocarbon production: 1) Identification of water condensing out of the gas phase (i.e., water of condensation) as a potentially significant component of produced water from shale gas wells. 2) Detection of recent cross-formation flow of deep formation waters; and 3) Distinguishing between gas seepage at the surface due to natural pathways (i.e., natural seeps) vs. anthropogenic pathways. In the first study, I show that isotopes of water, in concert with salinity, can be utilized to identify water of condensation as a source of fluid in produced water from Marcellus shale gas wells in the Appalachian Basin. In the second study, I utilize a combination of 228Ra/226Ra and 87Sr/86Sr ratios to identify recent cross-formation flow that is supplying â??out-of-zoneâ?? water into Marcellus shale gas wells. My third study presents a strategy for the application of isotopic and molecular methods to distinguish between naturally seeping hydrocarbon gases (and associated water, where present) and anthropogenic releases in hydrocarbon-bearing basins throughout California. Collectively, these approaches hold promise for unraveling water and gas origin and chemistry in a variety of settings within hydrocarbon-bearing basins.
