Development and application of a type curve for gel damage identification in tight gas wells
Fracture treatments have been proved to be the effective and efficient method in stimulating tight–gas reservoirs. The key is to create a long, highly conductive fracture to increase the well productivity and ultimate gas recovery. Since 1960s, fracture damage mechanisms have been investigated by petroleum engineers, researchers, and field personnel to better understand what caused lower fracture ...

In-situ estimation of the methane generation rate for a wet and highly organic solid waste landfill
Significant investments in landfill gas utilisation projects are required at project commencement. The methane generation rate for the Villa Dominico Landfill in Buenos Aires, Argentina is 0.26 yr−1, a very high rate as a result of the high organic content in the waste, and high moisture conditions within the refuse. The implications for landfills is that landfill gas recovery projects must be ...

Effect of the number and length of zonal isolations on pressure behaviour of horizontal wells
Horizontal wells with multiple zonal isolations have become a common completion technique in the oil and gas industry. Sand problems, damaged zones, and water or gas coning are the main reasons for using isolators to sustain or improve oil and gas recovery. However, they have certain effects on pressure behaviour of horizontal wells. This paper introduces new analytical models for studying the ...

SF6 gas recovery for maintenance of high voltage equipment - Case study
Starting position / boundary conditions SF6 gas is a halogen compound, which as a greenhouse gas has a very harmful effect on the environment. It can remain stable in the atmosphere for 3200 years. The greenhouse effect for SF6 is 23'900 times as large as for the same quantity of CO2. In the 1997 Kyoto protocol, SF6 was listed as one of the six greenhouse gases which are prohibited from freely ...

EPA mandates proper refrigerant gas recovery processes
New EPA regulations require facilities that use air conditioning and refrigeration equipment to have a refrigerant recovery plan in place. The plan is needed to make sure that any harmful gases that might leak are captured. Refrigerant gases contain hydrochlorofluorocarbons, known to cause severe damage to the ozone layer and to promote global warming. A comprehensive plan is now in place to ...

Prediction of three–phase saturation profiles from two–phase capillary pressure curves as a function of wettability
Gravity drainage of oil with gas is an efficient recovery method in strongly water–wet reservoirs and yields very low residual oil saturations. However, many of the oil–producing reservoirs are not strongly water–wet. Thus, predicting the profiles and ultimate recovery for mixed and oil–wet media is essential to design and optimisation of improved recovery methods based on three–phase gravity ...

Economic evaluation of a landfill system with gas recovery for municipal solid waste management: a case study
Economic activity uses resources, which leads to waste generation. With rapid industrialisation and urbanisation, per capita solid waste generation has increased considerably. Solid waste generation data for last two decades shows an alarming increase. Owing to its improper and untimely collection, the transport and disposal of municipal solid waste poses a severe threat to various components of ...

Estimating national landfill methane emissions
This paper estimates national methane emissions from solid waste disposal sites in Panama over the time period 1990–2020 using both the 2006 Intergovernmental Panel on Climate Change (IPCC) Waste Model spreadsheet and the default emissions estimate approach presented in the 1996 IPCC Good Practice Guidelines. The IPCC Waste Model has the ability to calculate emissions from a variety of solid ...

Municipal solid waste - waste to energy conversion in India: an overview
Municipal solid waste (MSW) is generated in enormous quantities, in India, causing environmental problems. It is collected primarily by sweeping in India and dumped on the outskirts of urban areas, which pollute the environment. Such MSWs also release methane and carbon dioxide, which are important greenhouse gases. MSW comprises biodegradable material. The MSW disposal methods in India mainly ...

Gas injection to increase recovery from the Bakken formation
The Bakken formation, in the Williston Basin, has tremendous oil reserves estimated to be in the hundreds of billions of barrels. During the last decade, the Bakken has been rapidly developed with advances in horizontal drilling and improved multi–stage hydraulic fracturing. The primary recovery factor, however, has remained very low, around 5%–10% due in part to the extremely low permeability. ...
