Geochemical and associated Changes with Gas-Water-Rock Reactions

Dear Colleagues,

The overall goal of this Special Issue of Geosciences is to explore and evaluate how gas-water-rock reactions impact subsurface and emerging technologies. Geochemical gas-water-rock reactions can modify rock properties such as porosity and permeability, affect water chemistry or leakage to drinking water aquifers, or can cause reservoir scaling and loss of productivity. They may also lead to benefits such as resealing cap-rock through mineral precipitation, or enhancing gas shale permeability through calcite dissolution from fractures.

Specifically, this Special Issue aims to provide an outlet for rapid, widely accessible publication of peer-reviewed studies utilizing gas-water-rock reactions to understand, alteration of subsurface properties. This special issue aims to cover, without being limited to, the following areas:

• CO₂ storage: CO₂ rock reactivity, impure CO₂ reactions including SO₂, NOx, O₂, changes in porosity and permeability, water chemistry, and geomechanical changes after reaction etc.
• Shale or coal stimulation: acid, CO₂, or hydraulic stimulation of gas or oil shales or coals and reaction associated changes.
• Reservoir or wellbore scaling reactions including brine injection, EOR, EGR, and geothermal.
• Gas-water-rock or other reactions associated with energy storage including nuclear energy etc.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
