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 ...

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 ...

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 ...

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 ...

Keeping Everything Flowing - How process technology from ProMinent secures optimal flow for industry

by ProMinent Group - ProMinent GmbH  (Jun. 15, 2015)

Do you know about the flow? That warm and fuzzy feeling when everything is running perfectly? Transferred to the field of process technology, this ideal condition has been reached when all components within a processing plant interact perfectly with one another, when processes are executed efficiently, safely and economically and the system is ...

Maximum Efficiency for...Saving Water

by Baioni Crushing Plants Spa  (Jun. 12, 2015)

In an attempt to protect our ecological surroundings and minimize the negative effects of industrial processes, it is necessary to purify and recover the waters used during washing operations of sand washing, quarrying and recycling operations. The first step is to recover 100% of the waters used and to eliminate the concentration of sludge, thus ...

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. ...

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 ...
