ROTARY WASH DRILLING

Terra-Ex performs rotary wash projects weekly. We have designed simple systems that enable us to switch from auger to rotary wash in a matter of minutes. Our approach is to keep diameters down to a minimum for faster production, less water usage, less drum usage, and overall cleanliness. Our efficient systems allow for more production, faster clean up, which results in a clean and safe operation for our field personnel and clients.

Terra-Ex can haul and dispose of drums on our geotechnical projects. In most cases, all the drums used on a project can be hauled away the same day. Once tested, all drums are disposed of at the appropriate facility. A manifest can be provided to our clients when testing and disposal has been completed.

Terra-Ex has both HQ and PQ Wireline Casing Advance Systems. The casing is drilled down with a bit locked into the bottom. Once the target depth is reached, a wireline retrieval tool can be used to extract the bit. Once the bit is extracted, SPT, Mod Cal, Shelby Tubes, or Piston Samplers can be used in a cased hole.
