A ‘Gas Operated Automated Lift Pump’ has been conceptually developed constructed in prototype and determined to be applicable for use in removing fluids from “stripper wells” thereby increasing production of natural gas. Bench scale and laboratory test of the key tool component, the automated pressure controlled valve assembly, has established the potential applicability of a prototype tool in ...

Application of Compressed Natural Gas (CNG) in diesel engines has always been important, especially in the field of automotive engineering. This is due to easy accessibility, better mixing quality and good combustion characteristics of the CNG fuel. In this study the application of CNG fuel along with diesel oil in a heavy duty direct-injection automotive diesel engine is experimentally investi...

I study the California Alternate Rates for Energy program (CARE), which provides a price reduction for natural gas and electricity for low-income customers. Using approximately one million monthly observations from 70,000 households, I provide the first demand elasticity estimate for natural gas using a natural field experiment (around -0.38). I also provide the first benefitcost analysis of CA...

Modeling and simulation of unconventional reservoirs are much more complicated than the conventional reservoir modeling, because of their complex flow characteristics. Mechanisms, which control the flow in the reservoir, are still under the investigation of researchers. However, it is important to investigate applications of mechanisms which are present to our knowledge. This paper presents the...

Natural gas is the most popular fossil fuel in the current era and future as well. Natural gas is existed in underground reservoirs so it may contain many of non-hydrocarbon components for instance, hydrogen sulfide, nitrogen and water vapor. These impurities are undesirable compounds and cause several technical problems for example, corrosion and environment pollution. Therefore, these impurit...
