Paper presented at the SPE Annual Technical Conference and Exhibition, September 23–25, 2024
Paper Number: SPE-220803-MS
... Abstract CO 2 mineralization is very safe for long-term CO 2 geosequestration but requires huge amounts of resources. CO 2 storage in saline aquifers requires relatively fewer resources but is highly dependent on the formation/seal integrity. Using waste plastics-CO 2 gels to promote CO 2...

Paper Number: SPE-220704-MS
... Abstract Most oil and gas fields face the dual challenge of optimizing recovery and minimizing CO 2 and greenhouse gas footprint from depleting fields. Although tertiary recovery strategies including CO 2 and produced gas injection are adopted, the cost and miscibility uncertainty associated...

..., but this parameter is usually neglected in analytical and numerical unconventional reservoir modeling. This study presents a systematic and comprehensive evaluation on the coupled effects of capillary pressure and wettability on unconventional production and CO 2 sequestration. Mercury injection capillary pressure...

Paper Number: SPE-220990-MS
... Abstract Formation wettability alteration (WA) is ubiquitous in nature and relevant to many applications spanning from geological CO 2 storage to enhanced oil/gas recovery. WA and the induced capillary dynamics are of great significance in caprocks and shale reservoirs. However, the impact...

... greenhouse gas (GHG) emissions, more carbon in the form of CO 2 will be captured and stored underground in wells intersecting suitable reservoirs for storage. The long-term integrity of such wells is a considerable concern, given that CO 2 is a fluid that reacts with Portland cement and steel, which can...

Paper Number: SPE-221060-MS
... Abstract The storage of carbon dioxide (CO 2 ) in subsurface reservoirs is an important option for mitigating anthropogenic greenhouse gas emissions and addressing the global challenge of climate change. However, implementing carbon capture and storage (CCS) technologies involves many complex...

... flooding, the permeability of the fractured core was calculated using Darcy's Law. Then, the temperature of the oven was ramped up to the desired value to start the foam injection. The foam for the experiments in this work was pregenerated by injecting the surfactant solution and CO 2 into the sandpack...

... risk associated with gas storage, an accurate understanding of gas plume evolution during and after injection is essential. For two immiscible fluids (e.g., CO 2 and brine water), the displacement problem can be analyzed based on the gravity current theory, where a finite amount of fluid is injected...

... reacting with the dissolved CO 2 . Dissolution reaction is done by first making 300 cm 3 of 15 wt% of MEA and MDEA. In each solution, concentrated HCl (37% HCl) is added to lower the pH to ~7. This initial pH was selected so that it would have a similar pH to the CO 2 -saturated MEA/MDEA solution, and HCl...
