Development Of Water Production Type Curves For Horizontal Wells In Coalbed Methane Reservoirs, Praveen Kumar Burka Narayana
Development Of Water Production Type Curves For Horizontal Wells In Coalbed Methane Reservoirs, Praveen Kumar Burka Narayana
Graduate Theses, Dissertations, and Problem Reports (ETD)
Coalbed methane is an unconventional gas resource that consists of methane production from the coal seams. The key parameters for the evaluation of coalbed methane (CBM) prospects are the gas resources, reserves and deliverability. Coalbed methane reservoirs are dual-porosity media where the vast majority of the gas is stored in the low permeability coal matrix (primary porosity) by sorption. The flow to production wells, however, occurs through the coal's natural fracture system (secondary porosity), which stores relatively small amounts of gas, because coal matrix practically has no permeability.;For the gas to be released from the coal, its partial pressure must …

Using Blended Instruction To Teach Academic Vocabulary Collocations: A Case Study, M. Teresa Das Neves Seesink
Graduate Theses, Dissertations, and Problem Reports (ETD)
Learning second language vocabulary has always been a challenge for second language (L2) learners. Transferring new vocabulary to an active stage has been an even greater challenge.;In the 1990s, Lewis (2002a) proposed the Lexical Approach as a means to help L2 learners with vocabulary acquisition. This approach encouraged the teaching of vocabulary in chunks, or in other words, putting emphasis on collocations. Focus on vocabulary collocations was suggested by several researchers (Brown, 1974; Hinkel, 2004; Lewis, 2001). They supported the teaching of collocations via in-class exercises. Cobb (1999) and Kaur and Hegelheimer (2005) showed that the use of a concordancer---an …

The Effects Of Permeability And Well Completion On Methane Gas Production From Hydrate Bearing Reservoir., Gopal Ganti
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Earth’s store of hydrocarbons will no longer supply adequate energy to its growing economics and population. By then, a type of hydrocarbons called hydrates may be ready to take their place as significant sources of energy. Hydrates are also a special combination of two common substances, water and natural gas. If these meet under conditions in which pressure is high and temperature is low, they join to form a solid, ice-like substance. Vast volumes of sediments in the ocean bottoms and Polar Regions are conducive to hydrate formation. Gas hydrates are solid, ice-like crystalline materials which contain entrapped gas …
