1.0 INTRODUCTION

Oil & Natural Gas Corporation Ltd. (ONGC) under their tender ref MR/OW/MM/B-193/07(R)/2007intends to develop B-193 cluster fields comprising of seven oil /gas facilities viz. B-193A, B193AQ,B-172, B-178, B-179, B-180, B-28A and B-23A which are located in the Heera-Panna-Bassein blockof Bombay Offshore basin, about 60-90 km towards west of Mumbai city in water depth ranging from60 to 75m. The fields are in close proximity of giant Bassein gas field towards the south. ONGC hascarried out facilities optimization study for B-22 and B-193field development and included additionalfacilities.

The development plan of B-193 cluster fields has been conceptualized in order to monetize theresources from the discovered fields that are located in the vicinity of main B-193 structure. Thesefields are of marginal nature and have high H2S & moderate CO2 content.

Bassein Formation is the main oil bearing reservoir with minor oil/gas accumulations in Panna andMukta formations in B-193, B-178, B-179 and B-180 fields whereas Mukta formation is the mainreservoir in B-172 field with minor accumulations in Bombay and Alibaug formations. In B-28A field,Bassein and Panna formations are the main oil reservoirs followed by gas accumulation in Muktaformation. In B-23A field Panna formation is the main gas reservoir. These fields are in close

proximity and all of them, except B-23A, have shown high H2S concentration in the range of 6000 to24,000 ppm except in B-28A where it is reported as 40,000 ppm. The CO2 concentration in all theabove fields is of the order of 4 to 6 % except in B-23A where it reported as 6 to 11.8%.

The B-22 field which is at a distance of around 27 kms from B-193A process complex have 3 remoteplatforms which are gas producing where as B22 platform has gas as well as oil production. Oil

production from B22 platform shall be transported to B-193 AP process platform for furtherprocessing to separate oil, water and gas for which additional liquid handling facilities for 42000

BLPD at B-193 AP are provided. Additionally water treatment and pumping facilities, powergeneration, water injection at B-193AQ platform are provided which will have a 90 personsaccommodation.

For B-193 Field Development Project, tender ref MR/OW/MM/B-193/07(R)/2007, the following

major facilities are; B193-AP Well cum-Process platform.

B-193-AQ 90 men living quarter cum Water injection cum power generation facilities platform

bridge connected to B-193-AP.

B172A, B178A, B179A.B28A-A,B23A-A Wellhead Platforms.

Submarine pipelines of overall 116.5km of varying sizes

Modifications at BCP-B complex and tie-in with the Heera Trunk line.

2.0 SUMMARY DESCRIPTION OF SCOPE OF WORK/SUPPLY
