The key challenges for future energy resources of the worlds are expected from unconventional resources. Indonesia and Malaysia are neighboring countries which endeavor to discover shale gas. Therefore, a review of the non-marine Tertiary shales in the Pematang Group and Bampo Formation of the Central and North Sumatra Basin, Indonesia as well as the ...

Chemical Geology, 2004
There have been many studies devoted to trace metals and their value in assessing the paleoredox conditions of ancient marine deposition. Among them, molybdenum (Mo) is frequently cited as an effective proxy for sediments and sedimentary rocks. Recently, Helz et al. (Helz, G.R., Miller, C.V., Charnock, J.M., Mosselmans, J.L.W., Pattrick, R.A.D., Garner,

The US Versus Marine Shale Processors: Statistical Issues
Environmetrics, 1997This paper describes statistical issues that arose in a case concerning the violation of environmental regulations. In the proceedings the concept of the power of a test was used to demonstrate that the sample sizes of the studies submitted by the defense were too small to provide adequate evidence that the product in question was safe.

Pyrite and organic matter in Phanerozoic normal marine shales
Geochimica et Cosmochimica Acta, 1986Data have been obtained, from our own chemical analyses and from the literature, for the concentrations of organic carbon (C) and pyrite sulfur (S) in over 600 samples of Cambrian to recent normal marine shales. (Normal marine refers to deposition in oxygenated bottom water as evidenced by the presence of benthic fossils and/or indicators of ...

Laboratory studies of non-marine shale porosity characterization
Journal of Natural Gas Science and Engineering, 2016Abstract Porosity characterization is the basic and very important research direction in shale core experimental study because it affects the gas reserves and the design of fracturing treatment. In this paper, laboratory studies of porosity characters with non-marine shale core samples from Mesozoic Triassic Yanchang Formation in Ordos Basin of China

Chemical depositional environments of calcic marine black shales
Economic Geology, 1996The economically important black shale facies contains several discrete chemical groupings in visually similar rocks. We examined the elemental compositions of more than 300 black shales and anoxic sediments in order to understand the relation of their chemical variability to the depositional environment.

Toxicity of oil shale waste waters to marine algae
Fuel, 1987Abstract Bioassays using Nitzschia closterium, a common Great Barrier Reef diatom, were carried out on Fischer Assay-produced retort waters and leachates of oil shale, spent shale and ashed shale. The abilities of spent and ashed shale and activated charcoal to remove the toxic components of retort water were also studied.

Marine and Petroleum Geology, 2019
Abstract The Upper Triassic Chang 7 Shale and the Mississippian Barnett Shale, two remarkable shale systems that are considered promising unconventional shale oil/gas targets in China and the USA, respectively, have different kerogen types that formed under lacustrine and marine environments.

Unconventional Resources Technology Conference, 2015
Abstract Identifying distinct facies shifts within mudrocks has made it difficult to build sequence stratigraphic frameworks within fine-grained lithologies. Three cores from Lincoln, Pottawatomie, and Pontotoc counties and two outcrops at the Hunton anticline quarry in Murray County cover proximal and distal regions of the Arkoma basin ...
