Trenchless drilling is one of the fastest growing areas for shale shaker use other than in drilling oil and gas wells. Many of these shakers are used in conjunction with hydrocyclones, creating a mud cleaner.
Tunneling

Tunneling has been very popular and is being used more and more in the world. Tunneling is horizontal boring of a large-diameter hole while simultaneously laying pipe. This is typically done in cities for laying or replacing water and sewer pipe under buildings and heavily traveled roads. Nowadays, the subways have begun to carry out large-scale construction in the world, shale shakers have been given a more mission. To prepare for these operations or constructions, large-diameter vertical holes are excavated so that the drilling equipment are set up at the desired depth. The caisson is excavated slightly below the equipment level, creating a sump for the returned drilling fluids and Shale Shakers associated drilled solids. The returns are pumped to the surface by a submersible pump to a compact solids-removal system, which typically consists of a shale shaker and mud cleaner mounted over a small tank.
River Crossing

In order to run a pipeline under a river, a small-diameter hole is directionally drilled under the riverbed. The pipe for the pipeline is attached to the end of the drill string and pulled back under the river while a larger hole to accommodate the pipe is back reamed. During the laying of large-diameter pipelines, a substantial solids control system must be set up with multiple shakers, desanders, desilters, and centrifuges. Mud cleaners reduce drilling-fluids disposal volumes.
Fiber-Optic Cables
The laying of fiber-optic cables does not require large-diameter holes, and it is often done in residential or business areas where drilling fluid and drilled solids must be contained. Solids control systems for this application usually consist of only a small tank, pump package, and small shale shaker.
