Borehole drilling. In carrying out borehole drilling projects in Nigeria, I strongly advice every prospective client to assign a geologist with his borehole project. it is important for the client to also beware that we have different borehole types depending on your water need and affordability.

We have Direct shallow borehole and industrial(deepwell) borehole. Each one of these borehole types is designed to serve a particular purpose different from the other. In carrying out a drilling project, whether in the basement complex or sedimentary terrain, certain factors like underground water contaminants, depth of the fresh water aquifer, productivity of the well, septic contamination, mineralogical composition of the project site, salinity and so on, should be taken into consideration.

Note: A Geo-physical survey is highly recommended.

Geo-physical survey is a scientific method of acquiring geological and hydro-geological features of the earth through some standard recommendations and adopted applications. The acquisition data helps both the client and the geologist to make a better judgement.

Direct shallow borehole: This borehole type is the most common within lagos and its environs. It is the least expensive of all borehole types, the reason why it is called shallow borehole is because the borehole is not drilled to a far depth, it has active production sustainance and it is economically very affordable. In some challenging environments like victoria island, lekki, ikoyi, ajah, lagos island, satellite town, sango-tedo, etc. There is the possibility of saline contamination,sewage infiltration, organics, hydrogen sulphide(H2S) and run-off incursion in the shallow bed. It is therefore advised that water treatment plant be installed for safety, human health and environmental pressure

Industrial or deep borehole: This borehole type is the most reliable in terms of production capacity and resistance to contaminants infiltration. The aquifer is confined and deep depth located. This well production possess industrial capacity, the confine nature of the aquifer is safe from all quality interference . It is the most reliable of all the borehole types and is specially designed for bottle or pure water processing factories, large residence, hotels and high rise buildings, production factories, community water schemes,etc. The deep borehole is the most expensive of all the borehole types, because of the depth and the nature of materials involved in the drilling operations.

we can work both in BASEMENT AND SEDIMENTARY REGIONS
