MEOR (Microbial Enhanced Oil Recovery) Technology:
for enhanced oil recovery from stripper wells using microbes.
TERI and IRS, ONGC have jointly cultured a set of microbes that could survive temperatures as high as 90ºC, air pressure up to 140 kilograms persquare centimeter, and strong salinity with concentration levels ranging from 4% to 8%. Techniques used earlier for oil recovery employed microbes that could bear temperatures only up to 65ºC. TERI and IRS, ONGC cultured these stronger bacteria in simulated conditions of oil wells complete with high temperature, high pressure, and heavy salt concentration. The product was successfully tested in oil wells at Ahmedabad and Mehsana Assets and the rest, as they say, is history.read more
WDP (Wax Deposition Prevention) / PDB(Paraffin Deposition Bacteria): Oil well tubing and surface pipelines for the prevention and treatment of wax deposition in oil wells.
Paraffin depositions cause a loss of billions of dollars per year worldwide due to enormous cost of prevention and remediation, reduced or deferred production, well shut-in, pipeline replacements and/or abandonment, equipment failures, extra power requirement and increased man power needs.
Conventional technique to control paraffin deposition in the oil tubing was mechanical scrapping of tubing. Invariably scrapper used to trap in wax inside the tubing and then difficult to remove the scrapper from oil well tubing which cause damage of well and then work over job is required which is a highly expensive and plagued with other associated problems. Steam, chemicals and solvents are used to dissolve the paraffin deposition are also expensive, hazardous environmentally as well as fire hazard. Even, sometimes pipelines get burst due to pressure build up during the above process.

Oilzapper (Bioremediation) Technology:
for the bioremediation of oil contaminated sites, oily sludge and drill cuttings.
After seven years of extensive research work TERI developed an easy and cost-effective bioremediation process. Providing great significance to bioremediation in the worldwide effort to tackle incidents of oil spills, TERI has developed OILZAPPER – a consortium of crude oil and oily sludge degrading bacteria – deriving from various bacterial cultures existing in the natural environment. OILZAPPER is multiplied under laboratory conditions, mixed with carrier materials, and packed into reusable polybags for convenient transportation. TERI conducted field trials at multi-locations and the results were highly encouraging, resulting in complete reclamation of the land. OILZAPPER has been used successfully since 1996. So far more than 2, 85,000tonnes of oil soaked soil/oily sludge/oil contaminated drill cuttings/oil contaminated soil and water has been bio- remediated.read more
