An Overview Of Direct Push Drilling

By Jerry Wright


Direct push technology, shortened as DP, is a form of technology that provides subsurface logging, sampling and investigation technique which is fundamentally efficient for application in rather unconsolidated elements and formations that consist primarily of things like clay, sand, silt, some gravel, and many others. On this note, it is fundamental to have an in-depth analysis of direct push drilling.

These technological systems under discussion can be employed in performing water, vapor and subsurface surveys. In this regard, it is important to remember that they have the capability to obtain soil and groundwater samples, as well as installing pre-packed and standard assessing wells. In addition, these drills can also drill and set vapor points, inclinometers as well as piezometers. Also, it supports the injection of a wide range of remediation compounds.

There are many reasons that have propelled the popularity and recent demand for these forms of technology. Many people and companies are nowadays choosing to use these push drilling methodologies, mainly due to many factors.

Firstly, this modality has very small footprints unlike other forms. Thus, direct push is very ideal especially for smaller sites. This is mainly because it requires very minimal space particularly for operation, alongside the fact that it has the ability to drill smaller holes compared to other drilling options that are available today.

This method is also of great advantage as it has a very low impact on the environment. This is because the drill makes clean bore, meaning that there is minimal cuttings made on the ground there is very little or no unwanted waste and there is also no use of grease or foams that pollute the environment. Since the rigs used are smaller than those used in traditional methods, nonstop push drilling is the best method for remote areas and areas with limited access.

Also, apart from requiring a considerably lesser space for its operations, this technique has also been proven to drill smaller and more manageable holes, in comparison to other available alternatives. As such, this is yet another cardinal advantage that gives this drilling option an edge over other modalities.

The methodology under discussion also comes with higher productivity levels. When it is employed on the right and most suitable soil type, it has the potential to efficaciously and quickly produce considerably larger numbers or volumes of stellar quality samples. Interestingly, the samples can reach even past two to three hundred feet, per day. This is a noteworthy factor that also increases the overall advantages of this piercing method, further making it the noblest option.

Direct push machines ideally advance equipment and tools in the soil subsurface using things like percussion hammers, hydraulics and vehicle weights. Nevertheless, many of the larger machines used in this technology can also be equipped with coring tools and hollow stem augers. Conclusively, the technology has been designed to enhance efficiency, making direct drilling a prudent move.
