Title: Field‐scale well leakage risk assessment using reduced‐order models

Abstract

Abstract Oil wells that intersect a potential CO ₂ storage zone in a depleted oil and gas field may provide leakage pathways. It is essential to estimate the field‐scale leakage risk associated with these wells. In this study, a risk‐based approach is used to estimate the risk of leakage. Existing reduced‐order models for well leakage are used to quantitatively estimate well leakage rates for cased‐cemented, cased‐uncemented, and open wellbores. For each existing well that intersects the storage zone, we introduce the well leakage index (WLI), which accounts for wellbore geometry, distance from the injection well, buffer layers between the storage zone and underground sources of drinking water, and the nature of storage zone boundary type. For an initial injection well location, the total site well leakage index (SWLI) is calculated, which is the summation of the WLI for all of the wells. Next, the injector location is varied areally and SWLI is calculated for a specified number of potential injector well locations in the storage zone area. Small values for the SWLI correspond to low well leakage potential, indicating where injection well locations can be considered. The developed criterion provides a means to systemically find the areas with highest andmore »« less

Comparative wellbore integrity evaluation across a complex of oil and gas fields within the Michigan Basin and implications for CO ₂ storage

Journal Article Haagsma, Autumn ; Weber, Stephanie ; Moody, Mark ; ... - Greenhouse Gases: Science and Technology

Abstract Wellbore integrity is a fundamental aspect of site characterization and selection for storage in areas with existing or abandoned oil and gas wells. The condition of well cement, installed casing strings, and plugs determine if a well can sustain optimal hydrostatic pressures and prevent fluid migration. This is a necessary but underappreciated aspect of assessing potential storage sites when optimal and sustainable pressure conditions are critical for success. To apply the systematic wellbore integrity evaluation to realistic CO ₂ storage conditions, seven fields in the Michigan Basin were selected which were actively being used for CO ₂ injection formore »« less

Geologic carbon sequestration injection wells in overpressured storage reservoirs: estimating area of review

Journal Article Oldenburg, Curtis M. ; Cihan, Abdullah ; Zhou, Quanlin ; ... - Greenhouse Gases: Science and Technology

Abstract The Area of Review (AoR) under the US Environmental Protection Agency's (EPA) Class VI CO ₂ injection permit is defined as the region surrounding the geologic carbon sequestration (GCS) project where underground sources of drinking water (USDWs) may be endangered. Estimation of the AoR is based on the calculated reservoir pressurization due to CO ₂ injection and the associated potential to lift saline water into potable groundwater aquifers through open flow paths (e.g. wells) assuming the system is hydrostatic. In cases where the storage reservoirs are not initially hydrostatic, and in particular where they are overpressured, AoR estimation methodsmore »« less

Enhancing capillary trapping effectiveness through proper time scheduling of injection of supercritical CO₂ in heterogeneous formations

Journal Article González-Nicolás, Ana ; Trevisan, Luca ; Illangasekare, Tissa H. ; ... - Greenhouse Gases: Science and Technology

Abstract The impact of geologic heterogeneity on capillary trapping of supercritical CO ₂ (scCO ₂ ) has been recognized and appraised through laboratory experimentation and modeling. However, how different injection strategies can be optimized to improve capillary trapping has not received adequate attention. We present a study based on stochastic analysis to show the impact of injection scheduling on capillary trapping of scCO ₂ in heterogeneous geological formations. Improvement of trapping efficiency consists of maximizing the trapped volume within a predefined secure zone of the storage formation with the goal of avoiding plume intersection with potential leakage pathways.

Development and evaluation of the coaxial cable casing imager: a cost‐effective solution to real‐time downhole monitoring for CO ₂ sequestration wellbore integrity

Journal Article Li, Yurong ; Cheng, Baokai ; Zhu, Wenge ; ... - Greenhouse Gases: Science and Technology

Abstract CO ₂ leakage is a major concern in a geological carbon sequestration projects due to adverse environmental consequences, where the main leakage risk is identified to be along existing wells through a thick, low‐permeable cap rock. To pursue robust and cost effective real‐time downhole monitoring technology for CO ₂ sequestration wellbore integrity, a permanently deployed coaxial cable casing imager is developed and evaluated in laboratory in this paper. The prototype of the casing imager consists of evenly distributed coaxial cable strain sensors helically wrapped around the pipe. The system is deployed on both PVC pipe and steel pipe tomore »« less

Leveraging operational information from wastewater injection wells to evaluate CO ₂ injection performance for carbon storage applications in the Appalachian Basin

Journal Article Valluri, Manoj ; Sminchak, Joel ; Cumming, Lydia ; ... - Greenhouse Gases: Science and Technology

Abstract Geologic parameters, geophysical logging, injection testing, and operational metrics from wastewater injection wells were integrated to develop a preliminary design of a carbon storage facility in the Appalachian Basin. A scattered group of 10–20 commercial wastewater injection wells dispose off produced water from oil and gas wells in the region, utilizing a sequence of stacked deep saline formations for injection zones. These wastewater injection wells provide practical benchmarks for understanding the feasibility of carbon dioxide (CO ₂ ) storage. Geologic models were developed based on characterization data from the wastewater injection wells. Reservoir simulations were calibrated according to injectionmore »« less
