Horizontal Remediation Wells used in order to preserve military security
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 area of approximately 150,000 SF. Scope of Work: ...

HDD-Exploring and Navigating Through the Terrastellar Cosmos
The following excerpts are from a featured article that was originally published in Trenchless Technology. In the very recent past in a galaxy far, far away (actually M87 a mere 55 million light years away), the first images of a black hole were reportedly made deep in space. Pretty impressive stuff but a bit closer to home is the reality that horizontal directional drilling (HDD) activity is ...

VC5 Vertebrae data in high definition - Case Study
SITE Confidential Site in South, FL CONTAMINATION Solvents OBJECTIVE One age old issue for proper site characterization is inaccessibility. Most sites have some type of building or structure in the way of completing an easy assessment. Often a building lies near or directly on top of a source of contamination where it matters most. Some buildings lend themselves to gathering limited data ...

Principles of HDD Solids Control & Buyers Guide
Relative to the use of drilling fluids within the oil & gas industry, the use of drilling fluids within the horizontal directional drilling (“HDD”) industry, is new. As the use of HDD technology did not become mainstream until the 1980’s, it took another decade before drillers started to consider the use of basic drilling fluids. Even today, the amount of research and ...

Centrifuge Technology in Drilling Fluid Recycling
Drilling fluid additives and the water that contains them are an essential part and expense of successfully completing a horizontal directional drilling (HDD) installation, and the longer the bore and larger the product being installed, the more drilling fluids cost. Therefore, it makes economic sense to recycle drilling fluids by removing cuttings and recirculating the cleaned fluids. HDD ...
