Development and application of type curves for pressure transient analysis of horizontal wells in shale gas reservoirs

by Inderscience Publishers  (Sep. 19, 2014)

Even though significant progresses have been made in the past few years, there appears to be a lack of information regarding the characterisation of shale gas formations. A major purpose of this study is to demonstrate impacts of horizontal well geometries and gas flow parameters as well as shale gas reservoir system on horizontal well production ...

Effect of the number and length of zonal isolations on pressure behaviour of horizontal wells

by Inderscience Publishers  (Feb. 21, 2014)

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 ...

Horizontal mixers for secondary combustibles case study

by AVA - Huep GmbH u. Co. KG  (Apr. 14, 2014)

The manufacture of secondary combustibles from household waste, industrial waste and special waste in accordance with statutory requirements is to be a huge challenge for system suppliers in the coming years. Currently, at times, extremely differing substances are treated in such a way that they can be loaded into conventional furnaces. The most ...

Treatment of municipal wastewater using horizontal flow constructed wetlands in Egypt

by IWA Publishing  (Jan. 16, 2014)

The aim of this study was to evaluate the performance of two pilot horizontal flow constructed wetlands (HFCWs) with and without vegetation. Three types of plants namely Canna, Phragmites australis and Cyprus papyrus were used. The surface area of each plant was 654 m2. The flow rate was 20 m3 d−1 and the organic ...

Pressure behaviours and flow regimes of a horizontal well with multiple inclined hydraulic fractures

by Inderscience Publishers  (Dec. 4, 2012)

Hydraulic fractures have become a common stimulation application in the oil and gas industry, especially in tight formations. Published models assume the hydraulic fractures are vertical and symmetric. However, recent studies have shown that fractures are asymmetric and inclined with respect to the vertical direction and the axis of the wellbore. ...

Determination of horizontal in-situ stresses and natural fracture properties from wellbore deformation

by Inderscience Publishers  (Dec. 2, 2013)

Accurate and low-cost information on in-situ stresses and fracture properties is critical in reducing well costs and increasing well recoveries. In this paper, a hybrid model based on the displacement back analysis is proposed for determining the in-situ stress magnitudes and fracture properties at the wellbore scale using wellbore displacements. ...

Design, construction and performance of a horizontal subsurface flow wetland system in Australia

by IWA Publishing  (Nov. 13, 2013)

Malabugilmah is a remote Aboriginal community located in Clarence Valley, Northern NSW, Australia. In 2006, seven horizontal subsurface flow wetland clusters consisting of 3 m × 2 m wetland cells in series were designed and constructed to treat septic tank effluent to a secondary level (Total Suspended Solids (TSS) < 30 mg/L and ...

Evaluation of a Horizontal Well

by Directed Technologies Drilling Incorporated (DTD)  (Oct. 5, 2010)

Background: Air Sparging Air sparging is an in-situ remediation technology where air is injected into the saturated zone of an aquifer. It is an alternative to conventional ex-situ pump and treat systems for remediation of contaminated ground water. It is necessary to understand the pattern of air flow that will occur in the subsurface in order ...
