Things To Know About Direct Push Drilling

By Jerry Wright


Direct drilling or technology, often shortened as DPT, is a modality that uses the rigid weight of the rig intertwined with hydraulic hammers, with the core intent to advance tooling as well as instrumentation particularly through the soil subsurface. As opposed to rotary, drill cuttings do not get removed from the hole. Notably, the depth and also speed of penetration largely depends on the type of the soil, the precise weight as well as power of the rig, and also the size of the used sampler. Critically examining these and other crucial details regarding direct push drilling is thus vital.

The first importance is that this method has the ability to quickly gather soil and water samples for testing as compared to traditional methods. This is because the piercing team is able to take many samples at once and test them simultaneously. Secondly, the equipment used is easy to use and very mobile. This is of great advantage because this equipment is easily attached to the rear of trucks and skid loaders. This enables the exploring team to reach areas that traditional drilling methods could not reach easily.

Direct push pulling methods generally provide a viable option or alternative especially to traditional rotary modalities for investigation of not only unconsolidated formations as well as soils. As compared to other rotary drilling techniques that essentially use the removal of cuttings as well as rotation in a bid to advance the equipment or tools deep into the soil or subsurface, these machines usually advance logging tools as well as sampling using vehicle weight and also percussion hammers.

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.

First and foremost, this methodology ideally has very minimal or rather small footprints. In this vein, it is very ideal especially for slightly smaller sites, and this is based on the reason that it generally needs lesser volumes of space in order to undertake its operations.

Another notable advantage is that this type of water and soil sample collection is that it offers groundwater profiling that is precise. This is because it collects samples by cutting through layers of ground water which aids in measuring the extent of contamination hence gives better and more accurate results than the traditional method.

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.
