Abstract Increasing oil production in Trinidad and Tobago (T&T) by means such as Enhanced Oil Recovery (EOR) may be a more cost effective and less risky pathway, when compared to the drilling of exploration and appraisal wells. This is because the fields and reservoirs that would be considered for EOR projects are generally in an advanced state of delineation and there has been experience derived from production data for some time. Considering the scope/applicability of carbon dioxide EOR (CO2-EOR), the revitalization of such projects in T&T would aid in extending the use of CO2 to another purpose, given its useful properties and behaviour, before being emitted to the atmosphere. Five CO2 EOR pilot projects were implemented in South Trinidad, starting in the early 1970's. At that time, as it is now, Trinidad had abundant CO2 available as a waste product from the ammonia manufacturing operations at the Point Lisas Industrial Estate (PLIE), Central Trinidad. At present, consideration is being made for the reintroduction of CO2 pipeline transport, directed to suitable EOR candidate sites mainly in South Trinidad, focusing once more on CO2 sourced from the PLIE. Det Norske Veritas (DNV) has introduced a Recommended Practice (RP) on the Design and Operation of CO2 Pipelines (RP-J202), incorporating lessons learned from existing CO2 pipelines around the world. This RP provides guidance for managing risks and uncertainties during the lifecycle of a CO2 pipeline, including design, testing, inspection, operation, maintenance, and de-commissioning. This paper will use DNV-RP-J202 to present a guiding framework for the possible re-qualification of sections of the existing CO2 pipeline network in Trinidad for the reintroduction of safe and efficient CO2 pipeline operations. The re-qualification process entails the following steps: Initiation, Integrity Assessment, Hydraulic Analysis, Safety Evaluation, Premises, Re-assessment, Modification Alternative(s), Documentation and Implementation. On completion of the re-qualification process, the majority of the pipeline system may not be acceptable for reintroduction of CO2. Options for consideration can be an adjustment of the pipeline routes where sections of pipeline network are not in acceptable condition, or the development of a completely new pipeline network and/or new routes.

Presently, the only offshore project for enhanced oil recovery using carbon dioxide, known as CO2-EOR, is in Brazil. Several desk studies have been undertaken, without any projects being implemented. The objective of this review is to investigate barriers to the implementation of large-scale offshore CO2-EOR projects, to identify recent technology developments, and to suggest non-technological incentives that may enable implementation. We examine differences between onshore and offshore CO2-EOR, emerging technologies that could enable projects, as well as approaches and regulatory requirements that may help overcome barriers. Our review shows that there are few, if any, technical barriers to offshore CO2-EOR. However, there are many other barriers to the implementation of offshore CO2-EOR, including: High investment and operation costs, uncertainties about reservoir performance, limited access of CO2 supply, lack of business models, and uncertainties about regulations. This review describes recent technology developments that may remove such barriers and concludes with recommendations for overcoming non-technical barriers. The review is based on a report by the Carbon Sequestration Leadership Forum (CSLF).

Storing carbon dioxide (CO2 ) in oil reservoirs as part of CO2 -based enhanced oil recovery (CO2 -EOR) can be a cost-effective solution to reduce emissions into the atmosphere. In this paper, we analyze the economics of this option in order to estimate the amount of CO2 that could be profitably stored in different regions of the world. We consider situations in which the CO2 -EOR operator either purchases the CO2 supplied or is paid for its storage. Building upon extensive data sets concerning the characteristics and location of oil reservoirs and emission sources, the paper focuses on opportunities outside North America. Using net present value (NPV) as an indicator for profitability, we conduct a break-even analysis to relate CO2 supply prices (positive or negative) to economically viable storage potential.

More than half of the world’s oil and gas pipelines are classified as non-piggable. Pipeline operators are becoming aware there are increased business and legislative pressures to ensure that appropriate integrity management techniques are developed, implemented and monitored for the safe and reliable operation of their pipeline asset. The Kuwait Oil Company (KOC) has an ongoing “Total Pipeline Integrity Management System (TPIMS)” program encompassing their entire pipeline network. In the development of this program it became apparent that not all existing integrity management techniques could be utilized or applied to each pipeline within the system. KOC, upon the completion of a risk assessment analysis, simply separated the pipelines into two categories consisting of piggable and non-piggable lines. The risk analysis indicated KOC’s pipeline network contains more than 200 non-piggable pipelines, representing more than 60% of their entire pipeline system. These non-piggable pipelines were to be assessed by utilizing External Corrosion Direct Assessment (ECDA) for the threat of external corrosion. Following the risk analysis, a baseline external corrosion integrity assessment was completed for each pipeline. The four-step, iterative External Corrosion Direct Assessment (ECDA) process requires the integration of data from available line histories, multiple indirect field surveys, direct examination and the subsequent post assessment of the documented results. This case study will describe the available correlation results following the four steps of the DA process for specific non-piggable lines. The results of the DA program will assist KOC in the systematic evaluation of each individual non-piggable pipeline within their system.

Limiting the increase in CO2 concentrations in the atmosphere, and at the same time, meeting the increased energy demand can be achieved by applying carbon capture, utilization and storage (CCUS) technologies, which hold potential as the bridge for energy and emission-intensive industries to decarbonization goals. At the moment, the only profitable industrial large-scale carbon sequestration projects are large-scale carbon dioxide enhanced oil recovery (CO2-EOR) projects. This paper gives a general overview of the indirect and direct use of captured CO2 in CCUS with a special focus on worldwide large-scale CO2-EOR projects and their lifecycle emissions. On the basis of scientific papers and technical reports, data from 23 contemporary large-scale CO2-EOR projects in different project stages were aggregated, pointing out all the specificities of the projects. The specificities of individual projects, along with the lack of standardized methodologies specific for estimating the full lifecycle emissions resulting from CO2-EOR projects, pose a challenge and contribute to uncertainties and wide flexibilities when estimating emissions from CO2-EOR projects, making the cross-referencing of CO2-EOR projects and its comparison to other climate-mitigation strategies rather difficult. Pointing out the mentioned project’s differentiations and aggregating data on the basis of an overview of large-scale CO2-EOR projects gives useful information for future work on the topic of a CO2-EOR project’s lifecycle emissions.

Abstract Legacy oil production from Appalachian basin has been in a decline mode since 2013. With more than 80% of wells producing less than 15 bbl/day, there is a growing interest in economically and environmentally viable options for well stimulation treatments. Analysis of formation mineralogy and reservoir fluids along with history of well interventions indicated formation damage in many wells due precipitation of organics and a change in wettability being partially responsible for production decline rates in excess of forecasts. The development and properties of a novel cost-effective biosurfactant based well-stimulation fluid are described here along lessons learned from several field trials in wells completed in the Upper Devonian Bradford Group. This group of 74 wells, completed in siltstone and sandstone reservoirs were presenting more than 12 well failures annually across the field, which was attributed to the accumulation of organic deposits in the tubulars. Based on these cases, batch stimulation treatments using a novel fluid comprising biosurfactants were proposed and implemented field wide. The treatments effectively removed organic deposits, changed formation wettability from oil to water wet and resulted in a sustained oil production increase. Well failures were significantly reduced as a result of this program and the group of 74 wells did not have a paraffin-related well failure for 18 months. Results from this program demonstrates the efficiency of the green well stimulation fluids in mitigating formation damage, reducing organics deposition and in increasing oil production as a promising method to stimulate tight formations.

Abstract The five-year long United Nations campaign for the reduction of greenhouse gases in the atmosphere culminated in the Kyoto protocol of 1997. Since this Kyoto conference attended by nearly 160 nations, sequestration of carbon dioxide from industrial flue gases and its storage and/or utilization have been receiving significantly enhanced attention. According to the US Department of Energy, very little research and development has been done in the United States on promising options that might address CO2 capture, reuse and storage technologies. An exception to this is the utilization of CO2 for enhanced oil recovery. Over a decade of industrial experience has accumulated at more than 70 enhanced oil recovery sites around the world where CO2 is injected to improve oil recovery from waterflooded reservoirs. The accumulated experience in the US, where about 32 million tons of CO2 per year are being utilized in EOR, has amply demonstrated that the retention of CO2 in the reservoir is very high when the original pressure is not exceeded. Thus, CO2 injected enhanced oil recovery presents itself as a mature field-tested technology for sequestering CO2 at a low net cost due to the revenues from recovered oil and gas. Much of the CO2-EOR experience to date in the US involves the use of high-purity carbon dioxide for conducting miscible floods in conventional crude oil reservoirs. Due to the high costs associated with supplying high-purity CO2 to the reservoir, this process has seen limited commercial success. However, the past research at LSU and elsewhere has amply demonstrated that impure CO2 was also effective in enhancing oil recoveries. This makes the abundant supply of flue gases from fossil-fuel combustion operations a viable and cost-effective option without the need for separating CO2 from the flue gas mixtures. This paper attempts to review and synthesize the literature dealing with geologic sequestration of CO2 in EOR projects. The available data are analyzed both from EOR and CO2 sequestration points of view.
