Hydraulically fractured horizontal wells account for most ...

Hydraulic fracturing is a completion technique, meaning it is performed after the oil or natural gas well has been drilled. Like horizontal drilling, this technique has been practiced for many years, but it has only recently become a major part of U.S. production in combination with horizontal drilling.

Horizontal Wells: Technology Overview Report - CLU-IN

In this technique, an upper horizontal well is used to inject air (sparging), nutrients, and/or methane into a contaminated aquifer. These actions stimulate microbial growth and so increase the rate of contaminant biodegradation. The increased surface area provided by horizontal wells allows more

Completion Technologies | Bakken - Beyond the Boom

Commonly, the "plug-and-perf" stimulation technique is employed in wells with cemented liners. Plug-and-perf includes pumping down a bridge plug on wireline with perforating guns to a given horizontal location near the toe of the well. The plug is set, and the zone is perforated.

PE100 pipe can be installed by horizontal directional drilling

HORIZONTAL DIRECTIONAL DRILLING- INSTALLATION PROCEDURE. This technique involves drilling a pilot bore, generally along a closely defined shallow arc, and then, if necessary, enlarging the bore using a reamer or hole opener to create a bore large enough to accept the new PE100 pipe, which is generally pulled in behind a reamer.

Wellpoint Dewatering | Groundwater Engineering

A typical wellpoint system consists of a series of small diameters wells (known as wellpoints) connected via a header pipe, to the suction side of a suitable wellpoint pump. The pump creates a vacuum in the header pipe, drawing water up out of the ground. For long pipeline trenches, horizontal wellpoints may be installed by special trenching ...
