(Press-News.org)

A new study published in Engineering unveils the remarkable carbon storage potential of shale reservoirs utilizing CO2 fracturing technology. Conducted by a collaborative team from the PetroChina Research Institute of Petroleum Exploration and Development (Beijing), the National Key Laboratory of Continental Shale Oil (Daqing), and China University of Petroleum (Beijing), the research signifies a pivotal advancement in China’s pursuit of energy independence and carbon neutrality.

Shale reservoirs play a crucial role in China’s energy landscape, and the utilization of CO2 fracturing offers a dual benefit: not only enhance oil recovery but also promote large amounts of CO2 storage. The study, titled “Carbon Storage Potential of Shale Reservoirs Based on CO2 Fracturing Technology,” delves into the intricate dynamics of CO2 storage mechanisms within shale formations, utilizing real exploitation parameters from the GYYP1 well in the Songliao Basin.

Through sophisticated numerical simulations, the researchers uncovered the pivotal role of adsorption and diffusion in CO2 storage within shale reservoirs. Initial findings revealed that approximately 22.13% of CO2 was adsorbed during the fracturing process, with diffusion further augmenting CO2 interaction with the shale rock over time. This synergistic effect resulted in a remarkable 26.02% increase in CO2 adsorption, ensuring long-term and stable storage within the reservoir.

Key conclusions from the study demonstrate an impressive CO2 storage efficiency of 80.15% over a decade, showcasing the substantial potential of CO2 fracturing technology. Notably, the research highlights the concentration of absorbed CO2 around the horizontal well, underscoring the importance of diffusion in maximizing storage capabilities.

Moreover, extrapolations based on the GYYP1 well data project that approximately 1000 future wells in Gulong shale oil reservoirs could harness similar storage potential, amounting to nearly two million tons of stored CO2 by 2030. Such achievements hold significant promise for advancing energy security and aligning with China’s dual carbon goals of achieving a carbon peak and carbon neutrality.

This research sheds light on the immense potential of CO2 fracturing technology in not only enhancing oil recovery but also mitigating carbon emissions. By leveraging the natural storage capabilities of shale reservoirs, we can make substantial strides towards a more sustainable energy future.

This pioneering research underscores the importance of continued innovation in energy technologies and sets a compelling precedent for future developments in CO2 fracturing methodologies. As China intensifies efforts towards carbon neutrality, initiatives such as this play a pivotal role in shaping a greener and more sustainable future.

2024-04-18
A new study from the University of South Australia is putting people’s experiences of pelvic pain at the front of pain education to develop better pain management strategies and improved outcomes.   Persistent pelvic pain is an umbrella term for pain in the pelvic area (below the belly button) which may be accompanied by symptoms suggestive of gynaecological, lower urinary tract, bowel, sexual, and pelvic floor dysfunction.   In Australia, one in two women and people assigned female at birth experience persistent pelvic pain, with one in four reporting that pelvic pain affects their ability to undertake daily activities such as work, study, or exercise.   This ...

Study finds ChatGPT shows promise as medication management tool, could help improve geriatric health care

2024-04-18
Polypharmacy, or the concurrent use of five or more medications, is common in older adults and increases the risk of adverse drug interactions. While deprescribing unnecessary drugs can combat this risk, the decision-making process can be complex and time-consuming. Increasingly, there is a need for effective polypharmacy management tools that can support short-staffed primary care practitioners. In a new study, researchers from the Mass General Brigham MESH Incubator found that ChatGPT, a generative artificial intelligence (AI) chatbot, showed promise as a tool to manage polypharmacy and deprescription. These findings, published ...

Heart failure, not stroke is the most common complication of atrial fibrillation

2024-04-18
The lifetime risk of atrial fibrillation (a heart condition that causes an irregular and often abnormally fast heart rate) has increased from one in four to one in three over the past two decades, finds a study from Denmark in The BMJ today. And among those with the condition, two in five are likely to develop heart failure over their remaining lifetime and one in five encounter a stroke, with little or no improvement in risk evident over the 20 year study period. As such, the researchers say stroke and heart failure prevention strategies are needed for people with atrial fibrillation. Atrial ...
