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.

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...

... 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...

... 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...

... 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 petroleum system is overpressured...

... 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 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...

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...
