Improving the Efficiency of Underperforming Wells Brochure

Improving The Efficiency ofUnderperforming WellsMAINTAINING WELL PERFORMANCEThe performance of wells (vertical orhorizontal) generally degrades with time.Even the efficiency of a properly developedwell will decrease through time. In orderto maintain the highest well efficiency it isimportant to be able to identify the cause ofthe decreased performance and equallyimportant—the remedy. DirectedTechnologies Drilling has the tools and theexpertise to help you with underperforming wells.IDENTIFYING CAUSES OF WELL INEFFICIENCYThe first challenge is to understand the problem withthe well: is it siltation, bio-fouling, mineralization?Using water quality analysis, review of pumpingrecords and if necessary, in-well video, we can helpyou understand why your well performanceis decreasing. Well videos in horizontal wellsare complicated by fine sediment on the bottomof the well and frictional forces preventingDirected Technologies Drilling can help you identify the causesof decreased well performance and provide the development toolsnecessary to rehabilitate and maintain efficient wells.Lateral ThinkingYields Better SolutionsWELL REHABILITATIONDTD investigation video showingsand flowing into a groundwaterrecovery well.Directed Technologies Drilling, Inc.(DTD) is a leader in horizontaldirectional drilling (HDD) technology.Our objective is complete clientsatisfaction.

We havedeveloped specialized jetting, injection, pumping andvideo equipment specifically for horizontal well work.Our staff are trained in all aspects of well inspection andexpert at analyzing problems. We often find site conditionsmuch different than expected and have built our reputationon our ability to adapt and innovate on site to completethe job regardless of conditions.Directed Technologies Drilling, Inc.800.239.5950 :: info@horizontaldrill.com :: horizontaldrill.comthe camera moving deep into the well.Adaptations must be made to the typicalvertical well or sewer video camerato allow it to proceed without stirring upwell sediment. However, a visual record ofthe well screen can be very valuable indetermining the cause of well inefficiencies.IMPLEMENTING WELL REHABILITATIONOR MAINTENANCEThe second challenge can be implementingthe necessary rehabilitation or regularwell maintenance. Traditional vertical welldevelopment techniques (i.e., air lift) fail ordo not provide the necessary flow velocitiesto restore the well function. DTD hasdesigned unique development tools thatare specially adapted tohorizontal wells and allowsimultaneous pumping andjetting of the wellthroughout the well screen.CONTACT US TO LEARN MOREImproving the efficiency of yourunderperforming wells is one of ourprimary services.
