... in the Upper Cretaceous contribute to the effective petroleum systems in the basin. With an understanding of all possible generating source rocks in the Upper Cretaceous, an oil to source rock correlation, oil-to-oil correlation, and production allocation in the drainage reservoir is investigated. Weld County...

... Forks petroleum system is characterized by low-porosity and permeability reservoirs in the middle Bakken, Pronghorn, and Three Forks, organic-rich source rocks (lower and upper Bakken Shales), and regional hydrocarbon charge. The Three Forks has an intimate relationship with source rock maturity...

... well and a simple completion strategy for the lateral that would have significantly reduced costs while enabling equivalent production. The STACK field study was utilized by an operator to evaluate and understand the petroleum system across their acreage and enabled unique acreage utilization decisions...

... basin-centered gas fairway beginning at 2000m and continuing to over 4500m in depth. This fairway steps down from the basin margins into the depths of the Fitzroy Trough and is analogous and correlative to a similar petroleum system that hosts significant gas discoveries on the opposite margin...

... Abstract Production from organic-rich shale petroleum systems is extremely challenging due to the complex rock and flow characteristics. An accurate characterization of shale reservoir rock properties would positively impact hydrocarbon exploration and production planning. We integrate large...

... Abstract The Niobrara Total Petroleum System (TPS) covers an extensive area across the Rocky Mountain Region, USA. In the Powder River Basin (PRB), the petroleum system consists of source beds in the Upper Cretaceous Niobrara Formation as well as reservoirs in the Upper Cretaceous Frontier...

... of the source rock for each petroleum system have been determined, e.g., depositional environment, lithofacies, and geologic age. Furthermore, the thermal maturity of each oil sample was calculated using biomarker maturity-dependent ratios, not used in the statistical analyses to determine oil source. Recently...

... Abstract The Bakken shale oil play in the Williston Basin of North Dakota and Montana is one of the most prolific resource plays in the U.S. Here we describe play-wide geological and petrophysical characterization of the Bakken petroleum system as a context for determination of oil in place...

... in any shale play study. In addition, hybrid nature of the Bakken petroleum system where source and reservoir rock present within short depth interval adds complexity to the production interpretation and outlook of the play. One of the complexities is the contribution from the shaley Upper and Lower...

... are targeted through horizontal drilling – the Niobrara (A-C Chalks) and Codell formations. The Niobrara consists of alternating chalk and marl units, whereas the Codell Formation consists of a clay-rich sandstone; both were deposited within the Interior Cretaceous Seaway.

The simulated heat flow calibrated to vitrinite reflectance data from 26 wells suggests that a slight increase...

... Abstract The lower and upper Bakken shales are world class source rocks in the Williston Basin, sourcing reservoirs in the Bakken, upper Three Forks, and lower Lodgepole formations, which comprise the economically significant Bakken Petroleum System (BPS). 10 to 400 billion barrels of oil have...

... Summary The relative abundances and stable isotope compositions (d 13 C and 5H) of low molecular weight (C1-C5) hydrocarbons are key parameters for determining the origin of natural gases and interpreting thermal maturity in unconventional petroleum systems. Gases released from drill cuttings...

... Abstract The Three Forks Formation is an important part of the Bakken Petroleum System of the Williston Basin. The USGS estimates that 3.7 billion barrels and 3.5 trillion cubic feet of gas can be technically recovered from the Three Forks. The formation is currently being developed...

... oil originates from Ordovician source rocks, but they are important sources for some petroleum systems. Some examples include, the Albion-Scipio field, the only giant field in the Michigan Basin, which contains petroleum generated from Ordovician Trenton-Black River source rocks and the very...

... Liquid-rich unconventional petroleum systems have become a significant worldwide exploration target with increased activity over the past years. Unlike the conventional system which requires off structure generation and migration, the liquid-rich unconventional petroleum system requires little...
