Formation Pressure Calculation Of Tight Sandstone Gas Reservoir Based On Material Balance Inversion Method, Wu Nan, Shi Shi, Zheng Shiqi, Zhao Haoyang, Wang Hongya, Tong Jiangnan

Coal Geology & Exploration

Pressure is the soul of a gas reservoir. Formation pressure is the basis of evaluating gas well productivity and analyzing gas reservoir potential. However, due to data integrity and method applicability limitations, formation pressure in most gas wells cannot be accurately obtained. On the basis of a small amount of pressure monitoring data, the material balance inversion method is proposed by using mathematical inversion thought to evaluate the formation pressure of tight sandstone gas reservoirs. Firstly, the dynamic reserves of gas wells are calculated by fitting the Blasingame chart with the production data of gas wells under pseudo-steady flow. Secondly, …

Deconstructing Consciousness In Art, Leila Kincaid

Journal of Conscious Evolution

To the extent that art mirrors consciousness, what does the art of any age have to tell us about where we are as a species and civilization? In this paper, I suggest that modern and postmodern art reveals the tendency toward deconstruction, of our identities, as selves, as cultures, and as a civilization. Through this process of deconstruction, there is a space offered to us through the experience of art, of freedom to recreate ourselves, our identities, and our sense of purpose and meaning in the cosmos. Grounding the inquiry in texts from various authors in the field of art …

Myth, Soul, And The Feminine

Journal of Conscious Evolution

What are some of the root causes that have caused the subjugation of women? Could it all have begun with the fantastical and alluring myths we were told? If so, how does myth become truth for societies as a whole? If that does happen, then it must be true that the mythic is where the emergence of the soul is found; the soul of humanity? Thereby, creating the realities found in the society of today. Even more intriguing is how consciousness and art find their way in merging with myth producing awareness, wonder, and connection in society. Thus, revealing the …

Consciousness, Evaluation, And The Self-Organizing Brain

Journal of Conscious Evolution

While evolution is guided by natural selection, it is internally driven by self-organizing processes. The brain encompasses these complementary forces and dynamics of evolution in both its structure and dynamics by embodying a historical record of the factors that have shaped it throughout its evolutionary past, as well as by being shaped by selective parameters in real time. Self-organization is evident in not only the brain’s structure and form, but also in the processes that support consciousness. From the convergence of complex structure and the novelty-generating dynamics of chaos that both characterize the brain arises the experience of explicit consciousness, …

Digitalizing Religion In The Age Of Covid-19: A Uses And Gratifications Perspective, Abdulaziz Altawil

Dissertations - ALL

The current COVID-19 pandemic has impacted people’s religious behavior around the world. Due to the coronavirus outbreak, most in-person religious services have shifted to virtual platforms. The online religious transition amidst the outbreak has alleviated many issues for worshippers as it provided them with a sanctuary space to connect with their faith and community. According to a 2020 Pew Research analysis, the pandemic has made many Americans change their religious habits by watching religious content online instead of physically engaging with their local religious institution. This dissertation provides a preliminary examination of this phenomenon by exploring the role of digital …

Due to the abundance of coal-bearing synclines, multiple seams and high gas content, the exploration area in North Yunnan and Guizhou Provinces is an important expansion block in the periphery of Junlian County. Based on a large number of coalfield holes and test wells, the geological conditions of CBM are analyzed, and the optimization and evaluation method of multi-layer favorable area is established, i.e. multi-level fuzzy mathematics plus key indicators. Firstly, the evaluation model is constructed based on hierarchical optimization, and the key indicators are determined as co-mining coefficient, coal structure and gas content. The co-mining coefficient is composed of …

Damage Mechanism Of Cbm Reservoirs And Double-Layered Screen Pipes In The Horizontal Well Completion, Xian Bao'an, Zhang Long, Ha Erheng Tu’Ersong, Yu Peng, Wang Kai, Zhang Yafei, Zhang Yang, Wang Sanshuai, Li Zongyuan

Coal Geology & Exploration

Coal reservoirs have the characteristics of high adsorption, low permeability, easy compression and easy breakage. At the drilling and completing stage of horizontal coalbed methane wells, coal reservoir damage often occurs and leads to a significant reduction in coal seam permeability, thereby resulting in single well production. Through experimental analysis, the solid phase particles in drilling and completion fluids for horizontal well and the solid phase components induced by fluid flow are found to block the micro-fractures in the coal reservoir, and the damage mechanism for coal reservoir is elucidated to the drilling and completion reservoir of the horizontal well …

Where’S The E In Oe? The Mcdonaldization Of Irish Outdoor Education, John Pierce, Simon Beames

Publications

This paper presents key findings from a study that aimed to critically examine the practice of outdoor education in the Republic of Ireland. It consisted of 10 months of fieldwork across four public Outdoor Education and Training Centres (OETCs). Data were generated through participant observation, informal conversation, as well as centre websites. Findings from the thematic analysis are presented in the form of a creative non-fiction story—principally to protect the identities and centres involved. The findings were then interpreted through the theoretical lens of McDonaldization. Considering the dearth of outdoor education research in Ireland, McDonaldization provided a lens through which …
