Jubilant prepares for production testing in Tripura

Vol 13, PW 6 (27 Aug 09) Exploration & Production

Newly appointed Jubilant Energy chief executive Ajay Khandelwal must be a happy man.

Within days of his formal appointment as company CEO, the Bhartia family-owned Delhi-based explorer is believed to have struck gas while drilling the Kathalachari-I well in Tripura, near the border with China. Kathalachari-I is the second in a seven-well minimum work programme at NELP-IV exploration block AA-ONN-2002/1, where Jubilant is operator with 20%, alongside GAIL with 80%.

Details are scarce but PETROWATCH learns Jubilant is excited about the â€کstrike’ and is gearing up to begin production testing next month using a 550-hp rig hired from Mumbai-based Dewanchand Ramsaram. “Dewanchand is mobilising the rig from Assam,â€‌ confirms an industry source.

“It should reach the site by September 10.â€‌ Spud in June, Kathalachari-I was drilled to TD of approximately 3200 metres by a 1300-hp rig owned by Delhi-based drilling contractor Quippo Oil & Gas and showed traces of gas in the â€کMiddle Bhuvan’ geological formation.

“It took them (Jubilant) 74 days to drill the well,â€‌ reports a source. With help from Schlumberger, an in-house team from Jubilant is believed to estimate gas pressure of up to 9000-psi.

But so far no Drill Stem Test (DST) has been carried out. Excitement at Jubilant is tempered with a more sober assessment at GAIL, Jubilant’s joint venture partner, where technicians are less than enthralled by what they’ve seen.

“GAIL doesn’t believe the logs are that encouraging,â€‌ we hear. GAIL is also unhappy that Jubilant hired Dewanchand to carry out production testing, instead of using the same Quippo rig already on site.

“Why did Jubilant wait a month to carry out a production testâ€‌ questions a source. “If you are sitting on oil or gas you start production testing immediately to get a feel for it.

Why wait A drilling rig can also be used for production testing.â€‌ Contacted by this report no one at Jubilant, GAIL or the DGH would comment.
