Preparation of Oil-Based Foam Gel with Nano-SiO2 as Foam Stabilizer and Evaluation of Its Performance as a Plugging Agent for Fractured Shale

Geofluids, 2022
The development of natural fracture will lead to lost circulation, which will be likely to cause economic losses and reduce drilling efficiency. In order to solve this problem, an oil-based pressure-bearing foam gel plugging agent for fractured shale was

Stable Isotope Geochemistry of the Organic Elements within Shales and Crude Oils: A Comprehensive Review

Molecules, 2021
Over time, stable isotopes have proven to be a useful tool in petroleum geochemistry. However, there is currently insufficient literature on stable isotope geochemistry of the organic elements within shales and crude oils in many petroleum systems around

Mechanism and Controlling Factors on Methane Yields Catalytically Generated From Low-Mature Source Rocks at Low Temperatures (60–140°C) in Laboratory and Sedimentary Basins

Frontiers in Earth Science, 2022
Various studies have shown that geo-catalytically mediated methanogenesis could happen in immature to early-mature source rocks at temperatures ranging from 60 to 140°C based on a series of long-term laboratory heating experimental evidences. The results

Oxygen-enriched combustion mechanism of lignite

Thermal Science, 2020
In this work, thermogravimetric experiments were carried out in a thermogravi-metric analyzer under O2/N2 atmosphere with an oxygen content ranging from 21 vol.% to 70 vol.%. Malek method combined with iso-conversional method and non-isothermal method was employed to determine the burning dynamical function of lignite in high temperature ...

Study on the optimal design of volume fracturing for shale gas based on evaluating the fracturing effect—A case study on the Zhao Tong shale gas demonstration zone in Sichuan, China

Journal of Petroleum Exploration and Production Technology, 2021
Hydraulic fracturing is the key technology in the development of shale gas reservoirs, and it mainly adopts volume fracturing technology to communicate hydraulic fractures with natural fractures to increase the drainage area. In view of the difficulty in

Shared mechanism underlying unembedded and embedded enrichments: evidence from enrichment priming

ZAS Papers in Linguistics, 2018
In this paper, we use a priming paradigm to explore the mechanisms underlyingunembedded and embedded scalar enrichments. In particular, the aim is to see if localpragmatic enrichment could be a shared mechanism, involved in both. The two experimentspresented adopt Bott & Chemla's (2016) enrichment priming paradigm and test whetherunembedded and ...
