“…As ageing hydrocarbon fields approach the end of their productive and economic life [63,81,125], and as various options for their potential reuse, such as geological storage of CO 2 [3,50,127] or of energy [8,52,99] emerge, wellbore sealing issues are becoming ever more important [5,19]. In particular, effective plug and wellbore sealing procedures, ensuring long-term zonal isolation, are essential (a) for complying with increasingly stringent environmental regulations applying to well and reservoir abandonment [109] and (b) for enabling reuse of reservoirs in future applications [51].…”

Reaction-driven casing expansion: potential for wellbore leakage mitigation

It is generally challenging to predict the postabandonment behaviour and integrity of wellbores. Leakage is, moreover, difficult to mitigate, particularly between the steel casing and outer cement sheath. Radially expanding the casing with some form of internal plug, thereby closing annular voids and fractures around it, offers a possible solution to both issues. However, such expansion requires development of substantial internal stresses. Chemical reactions that involve a solid volume increase and produce a force of crystallisation (FoC), such as CaO hydration, offer obvious potential. However, while thermodynamically capable of producing stresses in the GPa range, the maximum stress obtainable by CaO hydration has not been validated or determined experimentally. Here, we report uniaxial compaction/expansion experiments performed in an oedometer-type apparatus on precompacted CaO powder, at 65°C and at atmospheric pore fluid pressure. Using this set-up, the FoC generated during CaO hydration could be measured directly. Our results show FoC-induced stresses reaching up to 153 MPa, with reaction stopping or slowing down before completion. Failure to achieve the GPa stresses predicted by theory is attributed to competition between FoC development and its inhibiting effect on reaction progress. Microstructural observations indicate that reaction-induced stresses shut down pathways for water into the sample, hampering ongoing reaction and limiting the magnitude of stress build-up to the values observed. The results nonetheless point the way to understanding the behaviour of such systems and to finding engineering solutions that may allow large controlled stresses and strains to be achieved in wellbore sealing operations in future.

“…Th e 4D surface seismic program has proved eff ective for monitoring CO 2 movement in the Sleipner CO 2 injection site (Utsira formation), 19 and the Weyburn oilfi eld. 7 However, the thin inter-bedded oil formation (average oil-layer thickness is 7 m) of the H-59 reservoir, poses a great challenge to the 4D seismic method. 20,21 Meanwhile, CO 2 cannot fully sweep whole oil layers due to the formation heterogeneity and gravity segregation.…”

Jilin oilfi eld is conducting the fi rst large-scale demonstration project on CO 2 storage and enhanced oil recovery (EOR) in the northeast of China. A comprehensive monitoring program has been designed and deployed in the target reservoir of block H-59 using a wide range of techniques to monitor the injection and production systems, the CO 2 migration fronts, and potential CO 2 leakage pathways. Tube fault detection, corrosion inhibitors, anti-CO 2 corrosion cement, and production dynamic analysis have been adopted to guarantee the safety at the well site. CO 2 movement in the reservoir is detected mainly by gas tracer, electric spontaneous potential measurement, and fl uid sampling. Nearsurface environmental monitoring is also conducted around the injection site. Field experience has shown that the monitoring targets should be focused on the reservoir, near-surface, and injection and production systems. Applying monitoring techniques to ensure the integrity of wellbores can not only prevent the leakage of CO 2 , but also avoid the blind expansion of monitoring program scopes. It is reliable and economical to take full advantage of techniques based on wellbores to monitor CO 2 movement in oil reservoirs with dense well patterns. Up to April 2013, nearly 21.7 × 10 4 tons of CO 2 has been injected without obvious leakage caused by integrity failure of wells or the geological structure of reservoir. More than 96% of injected CO 2 has been safely stored with the rest of injected CO 2 normally breakthrough in the production wells. The preliminary monitoring experience obtained can provide valuable guidance for the future enlarged Jilin project and other CO 2 EOR and storage operations.

“…Currently, a number of CO 2 storage operations and demonstration projects (e.g., Sleipner, Norway, 1996; Weyburn, Canada, 2000; Ketzin, Germany, 2006; Cranfield, USA, 2008; Otway, Australia, 2008) have been conducted around the world [3][4][5][6][7]. The first pilot project of CO 2 capture and storage (CCS) in China, the Shenhua CCS demonstration project, successfully completed its goal of injecting CO 2 at a rate of 100,000 tons/year into the onshore saline aquifer in the Ordos Basin [8].…”

A 100,000 t/year demonstration project for carbon dioxide (CO 2 ) capture and storage in the deep saline formations of the Ordos Basin, China, has been successfully completed. Field observations suggested that the injectivity increased nearly tenfold after CO 2 injection commenced without substantial pressure build-up. In order to evaluate whether this unique phenomenon could be attributed to geochemical changes, reactive transport modeling was conducted to investigate CO 2 -water-rock interactions and changes in porosity and permeability induced by CO 2 injection. The results indicated that using porosity-permeability relationships that include tortuosity, grain size, and percolation porosity, other than typical Kozeny-Carman porosity-permeability relationship, it is possible to explain the considerable injectivity increase as a consequence of mineral dissolution. These models might be justified in terms of selective dissolution along flow paths and by dissolution or migration of plugging fines. In terms of geochemical changes, dolomite dissolution is the largest source of porosity increase. Formation physical properties such as temperature, pressure, and brine salinity were found to have modest effects on mineral dissolution and precipitation. Results from this study could have practical implications for a successful CO 2 injection and enhanced oil/gas/geothermal production in low-permeability formations, potentially providing a new basis for screening of storage sites and reservoirs.
