OREANDA-NEWS. February 28 2011. ONGC in its 215th Board Meeting held on February 25, 2011 approved the ONGC Group Consolidated Financial Performance

ll.ONGC notifies three discoveries : one each in Cambay Basin and Krishna Godavari Onland Basin and one new pool discovery in KG shallow offshore basin         

l)ONGC in its 215th Board Meeting held on February 25, 2011 approved the ONGC Group Consolidated Financial Performance.

ll)Discoveries    

Since the last Board Meeting 3 discoveries have been notified to DGH by ONGC:            

New Prospect Discoveries        

1.Well Aliabet # 2, NELP block CB-OSN-2003/1, Cambay Basin:           

(Notified on 12.02.2011)            

Well Aliabet # 2 in NELP block CB-OSN-2003/1 of Cambay Basin was drilled to a depth of 2107m. One of the zones in the interval 1890 – 1896m, on testing produced gas @ 12884 m3/day and condensate @ 6 m3/day. Two more zones are yet to be tested.

This discovery has opened up a new play in Hazad member in the area and may facilitate the efforts to proceed for appraisal and delineation phase in the NELP block.    

It is notable that this area was explored earlier, as pre-NELP block CB-OS-I, by companies like VALCO, HARDY, ENRON and BGEIPL without any discovery.

On further testing after notification the well produced 77167 m3/day and 11 m3/day of condensate through 6 mm bean size. The lower production level previously was due to lower levels of drawdown.     

2.Well Malleswaram # 1, PEL block 1A in Krishna Godavari Onland Basin:         

(Notified on 17.02.2011)            

Well Malleswaram # 1 in PEL block 1A in Krishna Godavari Onland Basin was drilled to a depth of 4105m. The interval 3518 – 3509.5m and 3508.5 – 3503m on testing produced oil @ 47.52 m3/day and gas @ 11124 m3/day. The oil produced has an API gravity of 460.   

This is a very significant oil discovery in synrift section in this part of the basin resulting from improved subsurface imaging through new 3D API. This discovery has a potential of being one of the very significant finds of KG onland basin.   

New Pool Discovery:     

3.Well GS-29#6, GS-29 PML, KG shallow offshore basin:           

(Notified on 17.02.2011)            

The well GS-29#6, drilled in the shallow offshore Krishna Godavari basin at a water depth of 95m, was drilled to a depth of 2502m. The well encountered interesting sands zones in the intervals viz. 2388 – 2424m, 2237– 2259m and 2278 – 2284m.          

The interval 2237 – 2245m (a new pool) on testing produced oil @ 570.33 m3/day and gas @ 118,925 m3/day through 32/64” choke. The oil produced is of good quality with gravity between 37.5 – 38.20 API.

In addition, another interval, 2390 – 2414.5m, on testing produced oil @ 617 m3/day and gas @ 123,400 m3/day through 32/64” choke. The oil produced is of good quality with a gravity of 380 API.        

Significant pay thickness and flow rates achieved in this well will boost, significantly, the scenario of integrated development of GS-29 fields with the discoveries of Northern Discovery Areas of NELP block KG-DWN-98/2.
