Four bacterial strains isolated from a mangrove swamp oilfield location in the Niger Delta of Nigeria were cultured aerobically in the presence of 1.0% waste drilling fluid, to determine the effect of the waste on their growth. The increase in activities of petroleum exploration and production has brought about an increase in the discharge of operational materials, such as drilling fluids and mud...
The abundance of sulphate-reducing bacteria (SRB) in oilfield waters from six land-based flowstations at different oilfields in the Niger Delta of Nigeria was determined over a period of six months, using the most probable number technique. All the oilfield waters contained SRB. However, their relative abundances varied with month of sampling. The highest count was obtained during the rainy season...
