The Eagle Ford Shale rig count gained one this week, increasing the total to 87 rigs running across our coverage area by midday Friday. In recent Eagle Ford news, Preferred Proppants announced last week it has begun commercial operations at its Atascosa sand mine and facility.

Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars. .
Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars. .
The micropile casing generally has a diameter in the range of 3 to 10 inches. Typically, the casing is advanced to the design depth using a drilling technique. Reinforcing steel,. .
Comprehensive fleet of rigs and tooling for difficult subsurface conditions and limited access Alleviates quality assurance concerns associated with cast-in-place piling in weak soils Can be combined with other techniques to meet unique or complex project requirements cost-effectively and efficiently .
The finished micropile (mini pile) resists compressive, uplift/tension, and lateral loads and is typically load tested following ASTM D 1143 (compressive), ASTM D 3689 (uplift/tension), and ASTM D 3966 (lateral). Capacities vary depending on the micropile size and subsurface profile. Allowable compressive capacities of more than 500 tons have. These drills are primarily used to drill tie-backs using a high-powered percussion head. They can also be equipped to drill using cased methods as required. The units can be mounted on a variety of excavator carriers to suit individual project requirements.
[pdf] A drilling rig is an integrated system that , such as oil or water wells, or holes for and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill , , or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called . Drilling rigs can s.
