The Main Purpose of Drilling Boreholes.
- Drilling for Water and water abstraction.
- Mineral Exploration and Survey.
- Exploration of Oil and Gas.
Boreholes are narrow drilling holes in the ground, either vertically or horizontally to purposely provide clean water or liquid like water, petroleum or gas.

Most engineers and environmental consultants use the phrase Borehole to describe all the various types of drilled holes.
Typically, most borehole drilling involves the digging of water wells by inserting vertical pipe which is termed as casing. Casing keeps the borehole from caving or expanding to bigger spaces or air spaces in the ground which can collapse the well.
To be able to get the right borehole for your purpose, make sure the engineer or the drilling manager has all the necessary equipments and is eligible with all resources.

Types of Wells
- Dug Wells
- Driven Wells
- Drilled Wells or Boreholes
Advantages and Disadvantages of Dug Wells and Boreholes
Dug Wells: This is digging in the ground with a spade, shovel, pickaxe or any other manual digging tool. This is the most oldest digging technique. One disadvantage is it is the most difficult or tiring. It also takes a lot of time to reach the depth where the water is especially on dry lands. The best condition to dig when the soil is moist or not hard enough or stuffed with stones to make digging difficult. Dug wells are all that deep, mostly between 10 and 20 metres or sometimes up to 40 metres. The advantage is it cost less to dig.
Drilled Wells or Boreholes: Modern wells uses the drilling method. This means the method of percussion is used where a tool in the soil or by using an action called rotary with a cutting tool, auger or drill bit to rotate or revolve around vertical axis. This breaks the rocks or grinds them and pulled up to the surface by sludging.
Mostly, drilled wells can be dugged up to 300 meters deep. The most techniques used are : Hand-auger drilling, Percussion drilling, Water injection, sludging, light motor-driven, rotary percussion drilling and rotary drilling. The main disadvantage of drilled wells is the cost. Borehole cost and prices continues to rise up. The average price in Ghana as of 2019 is 6000 Ghana cedis. But the good side or advantages are:
- Drilled wells or Boreholes are rich with minerals.
- They are not most of the time filled with chemicals like tap water which is always mixed with chlorine.
- Your property value increases or appreciates when you build one.
- You will get abundance of water to even water your garden and make your house beautiful.
Borehole Drilling Methods, Best Practices, Processes and Techniques
The following might be a little bit technical, however, as a seeker, you might be interested to know the right land information and the right technique so you might ask questions when the wrong methods are used. Most of the time, drilling methods ranges from less heavy duty machines to super heavy duty and sophisticated equipment. The following describes the type of soil formation and their right or suitable tools. Every formation of land must requires the appropriate tool and technique. The most common processes and methods are described below.
- Site Survey: When you find a drilling company. The first step they will take is to survey your site or premises. This includes finding the most suitable location for drilling, and also to calculate how deep the hole should be based on land formation.
- Estimates: As said previously above, you must compare the estimates of 2 to 5 companies to find the best affordable but yet credible.
- Drilling: This is when the company schedule a date when the drilling will begin. The most important thing to do is to check your neighbours or community to get approval before you start to prevent any unwanted distractions.
- Sampling for Bacteria: This is the most important stage. It involves sending samples to the lab to assess your water so the right treatment can be used. This is where if you are ignorant or you only went in for an amateur who doesn’t know what they are doing, you might be getting water but might contain bacteria.
- Water Treatment & Pump: When the lab results are ready, then the correct borehole equipments like casing, pumping machines and others are used to make your household water easily accessible.

Cable Drilling: Cable drilling is a method of drilling where an impact tool or drilling bit is suspended in the well or hole hanging from a steel cable. This cable is dropped recursively or beneath the soil in the hole to crush rocks and hard elements.
Auger Drilling: Auger Drilling is the process of using large or massive drill bit to make holes in deep soil with a rotation of the drill. The rotation of the drill bit causes the soil to be uprooted.
Rotary Air Drilling
Rotary air drilling method is used to make holes in hard compact or semi-hard soil formations like shales, sandstone. Uprooting of the sandstone or the hard rock formation is done with air compressor and fed down the drill pipe to be removed through a drilling bit.
This technique requires and advanced technician who knows the recommended up-hole annular velocity which is maintained to remove cuttings efficaciously.
