Return to Drilling Methods List. Cable-tool percusion Cable-tool drilling is a method in which a bit, hammer or other heavy tool is alternately raised and dropped to strike through the formation by breaking the soil or rock. Cuttings are recovered by adding water to the borehole (slurry), which is intermittently bailed out of the borehole.

Nickel Exploration in Oregon's Illinois Valley. The presence of nickel ore in southwest Oregon has been known for more than a hundred years but it wasn't until the late 1940s that interest in these deposits escalated with notable spikes in exploration happening in the 1950s, 1970s, and 1990s.
1) What is involved ? A technique used to sink wells more easily, more rapidly and to a greater depth than hand-dug or driven wells (See Sheets E29 and E30). A bored well is a cylindrical hole sunk vertically by percussion or the rotary action of a cutting tool (auger, drill bit) turning around a vertical axis. The diameter of a bored well can vary from 5 cm and 1.5 m.
4 SOIL COMPACTION HANDBOOK Figure 2 These illustrations show the results of improper compaction and how proper compaction can ensure a longer structural life, eliminating future foundation problems.
Baryte used for drilling petroleum wells can be black, blue, brown or gray depending on the ore body. The baryte is finely ground so that at least 97% of the material, by weight, can pass through a 200-mesh (75 μm) screen, and no more than 30%, by weight, can be less than 6 μm diameter.
Percussion drilling is suitable for unconsolidated and consolidated formations: Sand, silt, stiff clays, sandstone, laterite and gravel layers. Manual percussion drilling is generally used up to depths of 25 meters. Before drilling starts, it is good to analyse where the water might be.
of nickel-cobalt lateritic deposits is dependent on the part of the profile selected for mining. Plants may be deposit specific, though custom smelters operate in some parts of the world. MRMR estimates for nickel-cobalt laterites consequently require some unique considerations

The 26-in. hybrid bit was implemented to batch drill three hole sections, each approximately 3,400 feet long. The operator was able to optimize the drilling parameters for each successive well due to growing confidence in the stable drilling environment. This enabled the drillers to increase the ROP and greatly improve time savings.
The name "laterite" is a derivative of the latin word later, or "brick". A long time ago, bricks were carved out of laterites and used as building material in Asian countries such as India and Cambodia. The average grade and tonnage of nickel –cobalt bearing laterites …
The Pounder Rig places the more emphasis on drilling of a vertical hole, whereas the Baptist and Rota Sludge techniques emphasise very low cost wells. The Baptist and Rota Sludge techniques can be combined with stonehammer drilling to penetrate harder formations (eg laterite) whereas the Pounder rig is already designed for this.
