Doig shale grades upwards into a clean shoreface sandstone that in many areas is indistinguishable from the overlying Halfway Formation. Exploration to date has concentrated on thick shoreface sandstones that approximately form north-south oriented linear trends. Figure 2.
Shale gas is natural gas formed and held within shale formations. It is a fossil fuel originating from plant, algal or other remains, and composed primarily of methane (CH 4). Generally, shale formations are composed of fine-grained (less than 0.0039 mm in diameter) laminated sedimentary rocks made up of clay minerals (at least 30%), quartz, and
The Doig Formation, which has been historically viewed as a source-rock for conventional reservoirs in the Western Canada Sedimentary Basin, has become the focus of industry attention due to its potential as unconventional gas and natural-gas-liquids reservoir.
• the middle Colorado shale from the top of the Second White Specks Formation to the base of the Fish Scales Zone and • the lower Doig siltstone, which is equivalent to the upper Montney Formation in British Columbia. Assessments of these units take into account uncertainty at every step and
1 Ιουλ 2021 · We performed a comprehensive multiscale characterization analysis on the Longmaxi shale samples using five complementary techniques: low-temperature gas (N 2) adsorption (LTGA), mercury intrusion porosimetry (MIP), nuclear magnetic resonance (NMR), field emission scanning electron microscopy (FE-SEM), and X-ray computed tomography (CT) scanning.
SCIENCE ACTION PLAN FOR SHALE GAS IN THE KAROO BASIN i Foreword South Africa’s transition towards cleaner and more sustainable energy systems requires all stakeholders to understand the potential contribution and impact of the various energy resources available. The Cabinet’s approval of shale gas exploration in 2014
6 Απρ 2020 · In this work, the advances and challenges in the development of shale oil are summarized from following aspects: phase behavior, flow mechanisms, reservoir numerical simulation and production optimization.
