ONGC plans $19.36m Cauvery drilling
ONGC is planning to drill 30 onshore development wells at seven mining lease areas of the Cauvery basin in Tamil Nadu from May this year.
ONGC received environmental clearance for the Rs120cr ($19m) drilling programme on January 30 this year and is planning to drill five wells each at the 54-sq km Greater Narimanam ML area, the 17.8-sq km Adiyakkamangalam ML area, the 5.70-sq km Nannilam-I & II ML area, the 6.25-sq km Kuthanallur ML area and the 34-sq km Greater Kovikalapal ML area. Three wells will be drilled at the 20.6-sq km Kali & Kali-6 ML area and two at the 1-sq km Pundi ML area.
ONGC says it will use its own rig for the drilling campaign and will drill each well to about 3000 metres TD. Depending upon the formation, each well is expected to take 90-100 days to complete.
On completing the campaign, ONGC expects to produce around 2400 b/d of oil and 855,000 cm/d of gas. Once drilled the wells will be connected to established installations.
