THE PROCESS OF DEVELOPING A CO2 TEST INJECTION: EXPERIENCE TO DATE AND BEST PRACTICE Report: 2013/13 October 2013 INTERNATIONAL ENERGY AGENCY The International Energy Agency (IEA) was established in 1974 within the framework of the Organisation for Economic Co-operation and Development (OECD) to implement an international energy programme. The IEA fosters co-operation amongst its 28 member countries and the European Commission, and with the other countries, in order to increase energy security by improved efficiency of energy use, development of alternative energy sources and research, development and demonstration on matters of energy supply and use. This is achieved through a series of collaborative activities, organised under more than 40 Implementing Agreements. These agreements cover more than 200 individual items of research, development and demonstration. IEAGHG is one of these Implementing Agreements.

Background to the Study There are a significant number CO2 injection sites around the world of varying size, all of which could provide useful learning experiences for anyone attempting their first test injection. Many projects will have gone through project planning, risk assessment, permitting processing etc; the learnings of which may be useful for future projects. The purpose of this study is to document experience of the development of CO2 injection projects in order for countries looking to embark on their first CO2 test injection to refer to. This first test injection is considered to be in the order of 10,000 t CO2 per year. They will then be able to refer to the experience and lessons learned through the development and operation of CO2 test injection projects elsewhere in the world. The initial stages of any injection project will be a desk based assessment and initial site selection, followed by exploration and detailed site characterisation, obtaining permitting for injections and setting out a monitoring plan. Every storage site will have gone through various stages and processes before injection can start. These will differ depending on the size, location, local regulations and the geology of the site. However, the processes, if not the details may be common amongst all sites, including site characterisation and license permitting (though regulations will vary throughout regions). Many CO2 demonstration sites have been the first of their kind and regulations and permitting have developed alongside the project. For a country hoping to start their first injection it would be useful to be able to access one document that outlined the whole process with a timeline and pointed to relevant sources of information. There are several best practice documents and guidelines available; these vary in scope and technical detail. A number of non-site specific best practice guides have been produced, such as NETL’s risk assessment and site selection manuals and WRI’s CCS guidelines that outline the entire process. There are also best practice guidelines considering learnings taken from particular projects, such as the SACS, best practice for the storage of CO2 in saline aquifers, which uses, amongst others, learnings from the Sleipner storage site in the North Sea. Other examples of best practice guides are the QUALSTORE best practice guide and the EU Guidance documents. There are several documents outlining issues regarding public communication including guidelines from NETL and WRI. The Global CCS Institute recently commissioned CO2CRC to produce a summary of best practice guides, including a summary of the varying areas of coverage and technical detail. The document is publically available on their website: http://www.globalccsinstitute.com/publications/review-existing- best-practice-manuals-carbon-dioxide-storage-and-regulation. CO2CRC, a consortium based in Australia was commissioned by IEAGHG to undertake a study compiling learnings from test injections. Scope of Work This study does not intend to redo work already carried out, but to produce an over-arching document, which follows the process of setting up a test injection. This document would identify gaps in best practice guides as well as point readers towards available information. The document produced would order the steps and processes that the user would need to go through during the management of the test injection; from scoping of the project (including success criteria), site selection, planning, injection and closure. Many of the steps will happen simultaneously, but an order can still be established along with an expected timeline. This would be broad enough to allow for different permitting and legal processes in different countries as well as different site specific technical issues. The study was suggested to be carried out in 4 parts; The first part will be the identification of test injection projects. To date there has been a significant number of CO2 test injection projects conducted around the world including: Frio, Otway, Ketzin, Nagaoka, as well as a significant number of US Regional Partnerships Phase II projects. Each of these projects would have to have gone through significant planning and development before entering into operation. The projects identified should have relevance to pre-commercial CO2 test injections and pilot projects in the order of 10,000 t CO2 per year. The second part will be the identification of key development issues. For each project identified it would be valuable to document development information around project scoping, development of success criteria, project planning, planning a monitoring program, site selection, risk assessment, public engagement, legal and regulatory requirements, permitting, scheduling, costs, funding, staffing, skills required, management processes, reporting, reviewing and any unexpected hurdles and their solutions. The third part will be looking at trend analysis. Once information is gathered, trends across projects could be analysed identifying what processes are common across projects and when and why processes may differ. The fourth part will be the development of a test injection manual or best practice guide. Once information from existing projects has been gathered and trends analysed, a CO2 test injection development manual could be produced. This will be an overarching document with all the steps needed in the process of setting up a test injection. A follow-up of this work is the possibility of producing a webtool, whereby users will be able to enter information they have and be able to access the appropriate parts of the guide as well

    information t o u s e r s This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target” for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again - beginning below the first row and continuing on until complete. 4. The majority of usefs indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation.

Silurian rocks in Kentucky are exposed on the eastern and western flanks of the Cincinnati Arch, a large-wavelength cratonic structure separating the Appalachian foreland basin from the intracratonic Illinois Basin. The Cincinnati Arch area experienced uplift during latest Ordovician-early Silurian time, so that the exposed Silurian section is relatively thin due to onlap and post- Silurian erosional truncation on the arch. On both flanks of the arch, dolomitic carbonates predominate, but the section on the eastern side reflects a more shale-rich ramp that faced eastern Appalachian source areas. In the Silurian section on the western side of the arch, which apparently developed across a platform-like isolation-accommodation zone, shales are rare except dur- ing some highstand episodes, and rocks in the area reflect deposition across a broad, low-gradient shelf area, interrupted by structurally controlled topographic breaks. Using the progression of interpreted depositional environments and nearshore faunal communities, a relative sea-level curve, which parallels those of previous workers, was generated for the section in Kentucky. While the curve clearly shows the influence of glacial eustasy, distinct indications of the far-field, flexural influence of Taconian and Salinic tectonism are also present.

    A Quarterly Publication of the Division of Geological Survey Spring 1998 GEOLOGY OF OHIO—THE SILURIAN by Michael C. Hansen he Silurian Period occurred more than 400 million years ago in the middle of the Paleo- Tzoic Era. During this 30-million-year-long span, the climate and depositional environments were different than in any other span of time in Siberia Ohio’s geologic history. Sedimentary rocks of the Silurian System dominate the bedrock surface of Laurentia (North America) China the western half of Ohio, although their exposures are limited because thick glacial sediments cover all but the southernmost portion of the outcrop area. Baltica Australia Silurian rocks in Ohio are primarily carbonates— Ohio limestones and dolomites—and the many quarries in these rocks in western Ohio indicate their impor- tance. Silurian rocks in the subsurface of eastern Ohio contain extensive deposits of salt and accu- Africa mulations of natural gas and oil. In local areas in the Antarctica South America India western half of Ohio, magnificent scenery in the form of caves, cliffs, and waterfalls are unexpected Continental configuration during Silurian time (modified from C. R. Scotese and others, 1979, benefits of Silurian rocks. Paleozoic base maps, Journal of Geology, v. 87, fig. 14). The Silurian System was named by Roderick Impey Murchison, a Scotsman who eventually be- came the director of the Geological Survey of Great Britain. He first studied these rocks in Wales and NY named them after a Celtic tribe, the Silures. His MI monumental work, The Silurian System, was pub- platform/ lished in 1838. The lower part of Murchison’s Sil- pinnacle reef urian System overlapped with the upper part of PA Adam Sedgwick’s Cambrian System, a matter which became a great dispute between these two promi- OHIO nent geologists.
