Carbon Dioxide Storage and Sequestration in Unconventional Shale Reservoirs

Abstract

Carbon Dioxide (CO2) storage and sequestration in unconventional shale resources has been attracting interest since last couple of years due to the very unique characteristics of such formations have made them a feasible option for this object. Shale formations are found all around the world and the conventional assets are easily accessible, and also the huge move of operators toward developing unconventional reservoirs during past years leaves many of such formations ready for sequestering CO2. Today, the use of long horizontal wells that are drilled on a pad has the lowest amount of environmental footprint in which for storage and sequestration purpose also provides much more underground pore spaces available for CO2. In this paper we study the state of the art of the technology of CO2 storage and sequestration and provide different and fresh look for its complex phenomena from a mathematical modeling point of view. Moreover, we hope this study provides valuable insights into the use of depleted shale gas reservoirs for carbon sequestration, which as a result, a cleaner atmosphere will be achieved for the life of our next generations. Also, we present that the depleted shale gas reservoirs are very adequate for this purpose as they already have much of the infrastructure required to perform CO2 injection available in sites.

Experimental Deformation of Opalinus Clay at Elevated Temperature and Pressure Conditions: Mechanical Properties and the Influence of Rock Fabric

“…Clay-rich sedimentary rocks play also a fundamental role in many engineering applications, including the extraction of hydrocarbons as well as the exploitation of geothermal energy from unconventional deep shale reservoirs (e.g., Blackwell et al 2013;McGlade et al 2013). Due to a low hydraulic conductivity, high self-sealing potential as well as sorption capacity, clay-rich shales constitute potential host rocks for the storage of nuclear waste (Madsen 1998;Delage et al 2010;Sellin and Leubin 2013), and represent a suitable cap-rock sealing for the geological storage of carbon dioxide (Busch et al 2008;Boosari et al 2015;Bourgh 2015).…”

Effect of Heating Period and Temperature on the Synthesis of Nano-Beta Zeolite Assisted by Microwaves

“…This sample had a nano particles size distribution between 100-200 nm, BET surface about 632 m 2 /gr, and Si/Al ratio around 13. Noticeable impact on application of nano-betazeolite in enhancing shale oil and gas recovery and CO 2 sequestration could be observed by this improvement [19][20][21].…”

Predicting the Dynamic Parameters of Multiphase Flow in CFD (Dam-Break Simulation) Using Artificial Intelligence-(Cascading Deployment)

“…Reducing the time process compared to CFD was the main objective of the research, thus this process took 8 h with four processors when it was done by CFD and took 2 min by smart proxy with one processor. A noticeable impact in the application of AI for the prediction of the dynamic parameters could be observed in the enhanced shale oil and gas recovery and Co 2 sequestration [24][25][26].…”
