An investigation carried out by Nairametrics has revealed that there are 7, 296 oil wells in Nigeria. Some of the oil wells were last drilled as far back as November 1938 (for prospecting purposes) and as recent as December 2008.

Based on the data cited by Nairametrics, 74 companies and 1 unknown entity have been running Nigeria’s 7,296 oil wells between 1938 and 2020. This list compiles only 12 out of 75 operators. 

What to note 

In the data cited by Nairametrics, there are industry terms used. The terms are explained below for easier understanding;

  • Oil and gas show wells are exploratory wells where oil and gas have been encountered but have not proved to be commercially viable or productive. 
  • Plugged and abandoned wells have reached the end of their lifetime and have become dry holes. 
  • Suspended wells are not economically viable at the time they were suspended, but could be put back into production in the future. 
  • Water injector wells are used in the production of oil where high-pressure water is injected into the oil reservoir to increase oil recovery from an existing reservoir.   

Below is a list of the operators with the highest number of oil wells in Nigeria, from data last updated in 2020.

 What you should know 

  • An oil well is a hole dug into the earth that serves the purpose of bringing oil or other hydrocarbons like natural gas to the surface. Oil wells almost always produce some natural gas and frequently bring water up with the other petroleum products.  
  • There are different types of oil wells. A conventional oil well is drilled in the traditional sense, in that a location is chosen above the reservoir and the well is drilled vertically downward.  
  • Horizontal wells are drilled and steered to enter a deposit nearly horizontally. These wells can hit targets and stimulate reservoirs in ways that a vertical well cannot.  
  • Offshore wells are drilled in water instead of onshore.  
  • Multilateral wells are used occasionally and have several branches of the main borehole that drains a separate part of the reservoir.
