Pore Structure Characterization and the Controlling Factors of the Bakken Formation

The Bakken Formation is a typical tight oil reservoir and oil production formation in the world. Pore structure is one of the key factors that determine the accumulation and production of the hydrocarbon. In order to study the pore structures and main controlling factors of the Bakken Formation, 12 samples were selected from the Bakken Formation and conducted on a set of experiments including X-ray diffraction mineral analysis (XRD), total organic carbon (TOC), vitrinite reflectance (Ro), and low-temperature nitrogen adsorption experiments. Results showed that the average TOC and Ro of Upper and Lower Bakken shale is 10.72 wt% and 0.86%, respectively.

The Green and the Black: The Complete Story of the Shale Revolution, the Fight over Fracking, and the Future of Energy

Author: Gary Sernovitz

Gary Sernovitz leads a double life. A typical New York liberal, he is also an oilman – a fact his left-leaning friends let slide until the word “fracking” entered popular parlance. “How can you frack?” they suddenly demanded, aghast. But for Sernovitz, the real question is, “What happens if we don’t?”

Fracking has become a four-letter word to environmentalists. But most people don’t know what it means. In his fast-paced, funny, and lively book, Sernovitz explains the reality of fracking: what it is, how it can be made safer, and how the oil business works.

The Boom: How Fracking Ignited the American Energy Revolution and Changed the World

Author: Russell Gold

“Russell Gold’s The Boom is a double quest. He tells the story of the biggest innovation in energy so far in this century—the shale gas revolution. He captures the personalities, and the drama and surprises, and brings clarity to the debate about the environmental impact—and what it means for the U.S. economy and “energy independence.” But it’s also a more personal story – about “The Farm” in rural Pennsylvania where he spent time as a child, and his quest to understand what is happening in this new age of shale gas.” (Daniel Yergin, author of The Quest: Energy, Security, and the Remaking of the Modern World and of The Prize)

The Prize: The Epic Quest for Oil, Money & Power

Author: Daniel Yergin

This is a very well-written and neutral history of the oil and gas industry worldwide, from its beginnings in the U.S. in the 1850s up through the end of the Gulf War in 1991. I read this over perhaps eight months a couple years ago, having had been in the industry for about 18 years. I wish I’d read it when I first started working; I think my appreciation of my particular engineering field and its place in the context of the industry would’ve been greatly enhanced.

Geological characteristics, main challenges and future prospect of shale gas

The development of shale gas in the United States has made a breakthrough, profoundly changed the pattern of oil and gas supply. It created the “shale gas revolution” on a global scale. Based on the practice of shale gas development in China and abroad, this paper aims to: (1) Summarize 5 basic characteristics, which are shale gas resource distribution, reservoir space, sweet spot area (section), hydrocarbon type and development mode. (2) Divide China shale development into three stages: scientific exploration, technological breakthrough and mature development. The United States is divided into three stages: scientific exploration, technological breakthrough and mature development. (3) Identify 4 challenges in the future development of China shale gas industry.

Shale high pressure isothermal adsorption curve and the production dynamic experiments of gas well

The high pressure static adsorption curves of shale samples from Silurian Changning-Weiyuan Longmaxi Formation were tested by using high pressure isothermal adsorption equipment. The physical modeling of depletion production was tested on single cores and multi-core series by using self-developed shale gas fluid-solid coupling experiment system. The adsorption and desorption laws were summarized and a high pressure isothermal adsorption model was established. The calculation formula of gas content was corrected, and the producing law of adsorption gas was determined.

Molecular simulation of shale gas adsorption in organic-matter nanopore

Shale gas is a kind of unconventional oil-gas resource with tremendous potential. For thorough understanding of the methane adsorption and micromechanism in organic-matter nanopores of the shale and better acquaintances of the occurrence form, graphite slit-pores were set up as a representation of organic-matter nanopores by using Material Studio, and the grand canonical Monte Carlo method, molecular mechanics and molecular dynamics were used for the simulation of adsorption and diffusion behaviors in organic-matter pores on CH4 and CO2 at the shale gas common burial depth of 2–4 km in the Upper Yangtze Plate.

The effect of interbedding on shale reservoir properties Kimmeridge Clay Formation

-Shale/sand interbeds of the Kimmeridge Clay Formation generate a ‘hybrid’ shale oil resource.
-Rock-Eval S1 (kg oil/tonne rock) monitors shale retention and sand storage of oil.
-About 50% shale/50% sand and low TOC provide optimum oil retention and storage.

North Sea oil is overwhelmingly generated in shales of the Upper Jurassic – basal Cretaceous Kimmeridge Clay Formation. Once generated, the oil is expelled and ultimately migrates to accumulate in sandstone or carbonate reservoirs. The source rock shales, however, still contain the portion of the oil that was not expelled. As a consequence such shales and juxtaposed non-source lithofacies can form the targets for the exploration of ‘unconventional oil’.

-Nanoparticles based muds and conventional muds were investigated.
-Shale swelling was minimized by using graphene nanoplatelets.
-Rheological performance was improved by using graphene nanoplatelets.
-HPHT filtrate volume was minimized by using graphene nanoplatelets.

Five different drilling mud systems namely potassium chloride (KCl) as a basic mud, KCl/partial hydrolytic polyacrylamide (PHPA), KCl/graphene nanoplatelet (GNP), KCl/nanosilica and KCl/multi-walled carbon nano tube (MWCNT) were prepared and investigated for enhancement of rheological properties and shale inhibition. Nanoparticles were characterized in drilling mud using transmission electron microscope (TEM) analysis. Mineralogical analysis of shale was examined by X-ray diffraction (XRD). Five shale plugs were prepared using compactor cell for the determination of shale swelling. Shale swelling was determined using the linear swell meter (LSM) for 20 hours.

Three-dimensional characterization of micro-fractures in shale reservoir rocks

Fractures are crucial for unconventional hydrocarbon exploitation, but it is difficult to accurately observe the 3D spatial distribution characteristics of fractures. Microtomography (micro-CT) technology makes it possible to observe the 3D structures of fractures at micro-scale. In this study, micron-CT scanning is conducted on multiple mud-shale samples of source rocks in the Permian Lucaogou Formation, Junggar Basin. The Avizo® software is applied to process and segment the micron-CT images, so as to obtain the 3D fracture structure model inside rock core.
