Study of Public and Private Borehole Drilling in Nigeria
Existing data and information on drilling practices in the country and elsewhere was reviewed and about 70 sector players were interviewed. Prices of boreholes were collected from several programmes and projects as well as state agencies and compared with a systematic framework for analysis of borehole costs. Data was collected in the four states of Kano, Lagos, Niger and Rivers.
The report found that there are up to 1,000 private sector drilling companies in Nigeria. Drillers have realised the benefits of small light duty rigs and are using them where appropriate. Of the sampled rigs, 30% are made in Nigeria. Manual drilling was found to be more cost effective than mechanised drilling where feasible. Unfortunately, contract packages tend to be small, discouraging long term investment in equipment. Boreholes are often drilled deeper than they need to be and there is a tendency to specify geophysics on all drilling sites even where it is not necessary. The capacity for proper supervision in terms of experienced personnel and equipment is limited at state level, and post construction monitoring is rarely undertaken.
