Soil sampling often requires drills that can get into delicate and remote locations, whether that’s a back yard, wooded property or rural, rocky area. Our soil sampling rigs offer a variety of transportation options for accessing these challenging jobsites, ranging from trailer-mounted units light enough to pull with an ATV or UTV, to rigs that can be mounted on light- to medium-duty ...
Use of gas in drilling actually began several years before (2010) use of gas in frac operations (2013). ...
Intrinsyx performed a site assessment and came up with a systems design of strategic planting locations to exert hydrological control over the plume. The prime contractor drilled bore holes through soil, concrete, and asphalt, allowing Intrinsyx scientists and technicians to plant 600 hybrid poplar trees inoculated with its PDN3 bacterial endophyte. ...
As a background, the drilling methods traditionally used for geothermal projects have been the same drilling used for oil and gas projects. ...
That’s why at Strada Global we drill at a per metre rate instead of a per day rate. Or, to put it more succinctly, we only bill what we drill. ...
The falling prices of oil have derailed many drilling projects causing companies to take equipment offline and put it in storage either on site or at drilling contractor equipment yards. ...
In May 2018, a drilling contractor started the installation of 570 (6” diameter x 500ft deep) geothermal boreholes in Edmonton, AB, Canada. The project at the former Edmonton Municipal Airport started with 2-rigs drilling in a formation of clay, silt, and coal seams. It increased to multiple rigs before the successful completion in October ...

One of the most important functions of a drilling fluid is to stabilize and maintain a borehole opening. Borehole stability in coarse soils starts with creating an impermeable barrier between the soil and the drilling fluid or slurry via the filter cake (or polymer gel membrane for non-rotary mud drilling such as foundation ...

A few years ago, I received a call from a contractor asking for help mitigating a situation with a governmental transport agency in regards to monitoring downhole pressures as they were drilling under a six-lane highway crossing. They were asked to provide details on the drilling fluid they were using and the expected annular pressure while ...

All hammer parts are precisely machined to eliminate air leakage, boosting drilling penetration rates and optimising air consumption. Put To The Test The XT RC50 hammer design was conceived and developed in partnership with Drill King International's distributor for Chile, Argentina and Peru, Drillers Supply, which administered the drilling ...
Various organizations, such as the International Association of Drilling Contractors (IADC), publish Safety Alerts to promote safe practices. ...
So our designers worked shoulder to shoulder with our drill crews to come up with the innovation. That’s why TruCore really is a core-orientation system designed for drillers, by ...
Last October, a watermain break changed the perspective of a construction supervisor in Southwestern Ontario.. ason Smith of PV-Ex Construction was hired to oversee and install the site servicing for Lakeshore Ontario’s new multi-use Recreational Facility. This complex will include three ice pads, a gymnasium, aquatic center, indoor walking track, seven outdoor soccer fields and an outdoor ...
PROJECT: GPR survey with confirmatory drilling + soil and water sampling / analysis LOCATION: Spokane, Washington PROJECT DESCRIPTION: Designed and performed a tight-line / saturation Ground Penetrating Radar (GPR) survey of an active retail property, to determine the presence, if any, of buried 1950s-vintage underground storage tanks (USTs). Performed onsite instrument ...
DTI provided the horizontal engineering designs, well materials and worked with an in-country directional utility drilling contractor to install over 1,100 meters (3,300 feet) of horizontal piping, at an average depth of 4.5 meters (14.8 feet). ...
It took a contractor who was receptive to an innovative new installation approach, a good deal of patience and a whole lot of determination — after two previous attempts by other contractors using drills and air hammers were unsuccessful — to finally conquer a pesky 800-foot (243.8 m) stretch of tough Georgia blue granite. ...
