Nigeria’s largest indigenous swamp rig services provider

We made a bold entry in the oil & gas upstream services via OES Energy Services – an integrated oilfield services company. In demonstration of our high level of technical capabilities, the company is currently executing several oilfield services contracts in Nigeria.

With the aim of being Nigeria’s largest indigenous oilfield services firm and encouraged by the renewed local content drive in Nigeria, we have invested over $400m in the acquisition of five oil drilling rigs for use in the Niger Delta.
