Ireland’s Atlantic basins harbor the potential for major oil and gas discoveries in water depths ranging from 150 to more than 2,500 meters, according to the country’s Energy and Natural Resources office. Even so, exploration activity in the Irish offshore has been sporadic over the past four decades.

The title says it all: Determining Hydrocarbon Distribution Using Resistivity, Tuscaloosa Marine Shale, Southwestern Mississippi. The purpose of the study was to investigate the TMS Trend in southwestern Mississippi using electric logs and IHS’s proprietary Petra mapping software to document the structure, stratigraphy and hydrocarbon distribution.

DL Abstract

There has been a revival in the interest in hydrocarbon source rock characterization associated with the growing interest in unconventional resources where these fine-grained sediments represent the complete petroleum system. To-date, the primary focus has been on marine unconventional systems. Consider, however, if lacustrine systems may represent future unconventional opportunities in areas where the conventional resource-base is dominated by lacustrine-sourced oil. There are a number of key differences in the nature of these systems that should be considered when assessing.

DL Abstract

The enhanced production of unconventional hydrocarbons, the mitigation of biosourcing, and the advancement of carbon capture and storage, now combine to create significant financial and technical challenges to the global oil and gas industry.  Emerging and especially promising Geobiology approaches to these issues include utilization of the physical and biogeochemical activity of microorganisms that inhabit deeply buried hydrocarbon reservoirs.

DL Abstract

We have an unprecedented ability to realistically depict the spatial distributions of lithofacies in the subsurface thanks to developments in sequence stratigraphy, sedimentology, structural geology, geostatistics, and geophysics. As important as these developments have been, however, they in themselves have a limited ability to accurately predict rock properties–particularly in regions with high thermal exposures and restricted well control. We are developing a next-generation modeling platform that rigorously simulates processes in 3D at the grain scale. This 3D approach has the potential to provide unique predictive models of pore network geometries and grain contact properties for rocks in undrilled areas.

DL Abstract

With the growing global attention in shale gas and shale oil plays there has been a renewed interest in source rock geochemistry. This has resulted in a number of key questions concerning source characterization, including: 1) how much internal variability might be anticipated; 2) what is the potential impact of the variability on resource assessment; and 3) how best may a source be sampled to "fully" understand its variability?

DL Abstract

Reservoir characterization is an exercise in constraining uncertainty that arises from sparse sampling of the subsurface by widely spaced wells at lengthscales below seismic resolution. Outcrop analogs are an invaluable complement to well and seismic data in this context, because they provide qualitative concepts and quantitative spatial data to guide interpretations of lithology distribution in inter-well volumes. However, analog-driven interpretations of reservoir architecture are not straightforward to compare with dynamic data that describe fluid flow during production – the acid test of any interpretation of reservoir geology. The value of outcrop reservoir analogs is most fully realized when they are used to construct outcrop-based reservoir models that enable explicit predictions of flow patterns in a form that can be compared with routine reservoir-monitoring data.

DL Abstract

Organic-rich marine mudrocks are commonly interpreted to have been deposited in deep, quiet, permanently anoxic basins. While this appears to the case in some modern and ancient examples, field relations, regional correlations and sedimentological observations show that at least some widespread organic-rich may instead have been deposited in relatively shallow (<50 meters), moving water that at times had enough oxygen to support at least some life on the sea floor.

DL Abstract

Conventional hydrocarbon resources have been associated with pre-Devonian petroleum systems across the globe. Although individual accumulations can be quite significant, the relative importance of pre-Devonian-derived oils is limited compared to the global conventional resource-base. With growing interest in unconventional resources, the relative importance of these systems is expected to increase as plays develop.

DL Abstract

Hydrothermal alteration occurs when relatively high-pressure, high-temperature fluids flow up active faults and into permeable formations that underlie sealing shales, or other low permeability strata. This process can and commonly does occur at relatively shallow burial depths of less than a kilometer and in many cases less than 500 meters.
