Drilling operations generate large volumes of oily waste that threaten soil and water if left untreated. At Retaj Oilfield Services, we’ve developed a bioremediation process that transforms this waste into safe, reusable soil—using science, innovation, and nature itself.
Step 1: Waste Collection and Treatment
Oil-based drilling muds, cuttings, and sludge are carefully delivered to treatment sites. Retaj uses circular cyclone-inspired tanks to separate solids and liquids efficiently, cutting chemical use in half while improving result.
Step 2: Microbial Action
Indigenous bacteria—specially isolated and registered strains such as Bacillus and Pseudomonas—are introduced into the waste. These microbes consume petroleum hydrocarbons and prevent pollutants from seeping deeper into the soil.
Retaj’s bioremediation process shows that waste from drilling doesn’t have to be a permanent burden. With the right blend of technology , biology and responsibility . we turn oil waste into an opportunity for environmental renewal.
Step 3: Composting and Aeration
The waste is mixed with sugarcane bagasse, a natural byproduct that enriches the microbial environment. Continuous aeration and fertilization keep conditions ideal for bacterial growth and rapid biodegradation.
Step 4: Water Recycling
Up to 90% of wastewater from the process is purified and returned to drilling rigs for reuse in mud-making and washing operations. This reduces water demand and minimizes discharge into the environment.
Proven Results
Within just weeks, petroleum hydrocarbon levels (TPH) in treated soils drop to environmentally safe limits. The once-toxic material becomes stable soil that can support vegetation—helping restore oilfield land for future use.
