GSPC offers crude from 3 blocks

GSPC wants to exit the upstream business, but before that, it is not averse to making money selling oil from three of its producing blocks.

On August 7 (2021), GSPC issued a tender to sell 327 b/d of oil from three fields: NELP-II block CB-ONN-2000/1 (Ahmedabad), NELP-V block CB-ONN-2003/2 (Ankleshwar) and NELP-IV block CB-ONN-2002/3 (Sanand Miroli). By August 31 (2021), GSPC wants bids for the "emulsified crude" with large amounts of water mixed because of water cut trouble at the wells.

At the Sanand East field at CB-ONN-2000/1, cluster wells SE#1 and SE#1A are at a single location at Ghuma village on the western periphery of Ahmedabad city. GSPC is offering 189 b/d from this field.

Well SE#1 produces 75 b/d but water cut of 7.5 to 8%; well SE#1A has a maximum production of 12 b/d with a 10 to 15% water cut. Cluster wells SE-Dev#1, and SE1#A1 are at another location.

SE-Dev#1 produces 69 b/d but has a water cut of more than 55%; well SE1#A1 has a maximum production of 75 b/d with a water cut of more than 55%. At the Sanand field Part A at CB-ONN-2002/3 at Manipur village in Sanand, well SE#3 flows 45 b/d with a water cut of 12 to 18%; well SE#4 has a maximum production of 46 b/d with a water cut of 6 to 10%.

At CB-ONN-2003/2, well Ank#21 flows 50 b/d with a water cut of 15 to 20%; well Ank#40S has a maximum production of 18 b/d with water cut less than 1%. Oil from CB-ONN-2000/1 and CB-ONN-2002/3 has an API of 24-27 degrees, but CB-ONN-2003/2 has an API of 36-41 degrees.
