Horizontal Wells - Technology Overview

by Groundwater Remediation Technologies Analysis Center  (Jan. 1, 1996)

Horizontal well technology has been incorporated into many current environmental remediation applications (and associated contaminants), such as in situ bioremediation, air sparging, vacuum extraction, soil flushing, free product recovery, etc. Ac cording to information reviewed, this technology is most applicable to sites with relatively shallow ...

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 ...

Time-Tested Advantages of Horizontal Wells

by Directional Technologies, Inc.  (Oct. 22, 2010)

Wells are wells are wells, right? Both conventional vertical wells and directionally drilled horizontal wells have a screened casing that is connected to solid riser casing which leads to the ground surface. Groundwater or soil vapor is drawn through a well screen to remove contaminants. Remediation agents such as air, bioamendmnents or potassium ...

Upgrade Fill Media to Improve Cooling Tower Efficiency

by Industrial Water Cooling (IWC) Pty Ltd  (Oct. 29, 2015)

One of the simplest and most cost-effective ways in which to extend the life of a cooling tower, improve heat transfer efficiency and reduce maintenance downtime, is to upgrade the cooling tower’s fill media to components constructed out of robust and non-clogging materials such as Polypropylene (PP), PVC or stainless steel. Fill is a ...

Constructed Wetlands for Domestic Wastewater Treatment and its Reuse in Irrigation

by IWA Publishing  (Nov. 8, 2015)

Introduction This project focuses on South Europe, the region important for tourism and agricultural production, both activities with high water demand. Mentioned region is already experiencing problems with water scarcity and the situation is expected to worsen according to the international prognosis (Angelakis et al, 1999). Climate change could ...

Horizontal Soil Vapor Extraction and Horizontal Air Sparge Wells Case Study-

by Directional Technologies, Inc.  (Jul. 6, 2011)

Directional Technologies Is The Expert At Horizontal Soil Vapor Extraction   A horizontal soil vapor extraction well and two horizontal air sparge wells rapidly remediate contamination in situ under a research and development facility. These horizontal wells were installed by environmental directional driller Directional ...

Electrical heating with horizontal wells, the heat transfer problem

by McMillan-McGee Corp.  (May 13, 2011)

Outline Present our mathematical solution of the axial heat transfer problem for electrical heating of a horizontal well. Present some results. Calculation Procedure Derive the Heat Transfer PDE for each region. Obtain the Laplace Transforms of these equations. Solve the above equations. ...

How much does a Horizontal Remediation Well cost?

by Directional Technologies, Inc.  (Oct. 22, 2010)

In the early days of horizontal remediation wells, the estimated costs made many projects completely unfeasible. However, with the advance of technology in directional drilling and innovative solutions within the environmental industry, this technology is becoming affordable and practical. Like most environmental projects, the cost of a Horizontal ...

Horizontal Remediation Wells used in order to preserve military security

by Directional Technologies, Inc.  (Nov. 11, 2010)

Project Description: Remediate a plume of trichloroethylene (TCE) under multiple military buildings by air sparging (AS) and soil vapor extraction (SVE). There are two target zones: the shallow zone is approximately 70' below grounds surface (bgs) and 20' below this is the deep zone. The plume was located under multiple buildings comprising an ...

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. ...
