Title: Engineering Prediction of Axial Wellbore Shear Failure Caused by Reservoir Uplift and Subsidence

Abstract

Injection and production can cause significant regional uplift or settlement. We analytically evaluate the potential for cement-annulus failure in response to injection-induced deformation in a coupled casing/cement/rock poromechanical vertical-well system. Deformation is calculated with respect to the initial near-wellbore stress state, occurring immediately after cement curing. Tensile-failure and shear-failure lengths along this well are predicted using a stress-development-length method. The analytical model is verified by Abaqus modeling. Lastly, a sensitivity analysis identifies critical engineering-well-design parameters for ensuring wellbore-annulus integrity.

Integrity of Pre-existing Wellbores in Geological Sequestration of CO2 – Assessment Using a Coupled Geomechanics-fluid Flow Model

Journal Article Kelkar, Sharad ; Carey, J. William ; Dempsey, David ; ... - Energy Procedia (Online)

Assessment of potential CO₂ and brine leakage from wellbores is central to any consideration of the viability of geological CO₂ sequestration. Depleted oil and gas reservoirs are some of the potential candidates for consideration as sequestration sites. The sequestration sites are expected to cover laterally extensive areas to be of practical interest. Hence there is a high likelihood that such sites will contain many pre-existing abandoned wells. Most existing work on wellbore integrity has focused on field and laboratory studies of chemical reactivity. Very little work has been done on the impacts of mechanical stresses on wellbore performance. This studymore »« less

Insights into the physical and chemical properties of a cement-polymer composite developed for geothermal wellbore applications

Journal Article Rod, Kenton A. ; Nguyen, Manh-Thuong ; Elbakhshwan, Mohamed ; ... - Cement and Concrete Composites

To isolate injection and production zones from overlying formations and aquifers during geothermal operations, cement is placed in the annulus between well casing and the formation. However, wellbore cement eventually undergoes fractures due to chemical and physical stress with the resulting time and cost intensive production shutdowns and repairs. To address this difficult problem, a polymer-cement (composite) with self-healing properties was recently developed by our group. Short-term thermal stability tests demonstrated the potential of this material for its application in geothermal environments. In this work, the authors unveil some of the physical and chemical properties of the cement composite inmore »« less

A numerical study on the feasibility of evaluating CO ₂ injection wellbore integrity through casing deformation monitoring

Journal Article Li, Yurong ; Nygaard, Runar - Greenhouse Gases: Science and Technology

Abstract Distributed sensing technologies have been increasingly used for downhole monitoring in the oil field in recent years. A casing deformation monitoring system based on distributed strain sensors has been developed and proposed for wellbore integrity monitoring. However, due to the lack of field data on casing deformation induced by various exploration and development activities, the relationship between casing deformation and wellbore integrity remains unclear. To study the feasibility of evaluating short‐term CO ₂ injection wellbore integrity through casing deformation monitoring, a staged finite element analysis is conducted for an existing well in the Weyburn field to study the relationshipmore »« less

Insights into the physical and chemical properties of a cement-polymer composite developed for geothermal wellbore applications

Journal Article Rod, Kenton A. ; Nguyen, Manh-Thuong ; Elbakhshwan, Mohamed ; ... - Cement and Concrete Composites

To isolate injection and production zones from overlying formations and aquifers during geothermal operations, cement is placed in the annulus between well casing and formations. Wellbore cement can fracture due to chemical and physical stress. A polymer-cement (composite) with self-healing properties, stable at high temperatures, was recently developed by our group. Here we present data on the elemental distribution, mineral composition, internal microstructure, and tensile elasticity of this composite and how it compares to cement without polymer (control cement). Entrapped air porosity was similar between control cement (0.44% by volume) and composite (0.22% by volume). Total voids increased with polymermore »« less

Field-scale and wellbore modeling of compaction-induced casing failures

Journal Article Hilbert, Jr, L B ; Gwinn, R L ; Moroney, T A ; ... - SPE Drilling and Completion

Presented in this paper are the results and verification of field- and wellbore-scale large deformation, elasto-plastic, geomechanical finite element models of reservoir compaction and associated casing damage. The models were developed as part of a multidisciplinary team project to reduce the number of costly well failures in the diatomite reservoir of the South Belridge Field near Bakersfield, California. Reservoir compaction of high porosity diatomite rock induces localized shearing deformations on horizontal weak-rock layers and geologic unconformities. The localized shearing deformations result in casing damage or failure. Two-dimensional, field-scale finite element models were used to develop relationships between field operations, surfacemore »« less
