Indian Sedimentary Basins

Basin Category
Category I
Category II
Category III
A new 3-tier category for 26 basins
Category III (“Prospective”) and Category IV
(“Potentially Prospective”) are now combined
A simplified approach to present the Category
based on the instances of ‘discovery’ and
‘commercial production’, closely in line with
PRMS ideology
Category I: 7 basins which are commercially
producing from established petroleum resources
(“RESERVES”)
Category II: 5 basins which have established
petroleum resources but are yet to produce
commercially (“CONTINGENT RESOURCES”)
Category III: 14 basins which have prognosticated
resources assessed but still to find hydrocarbon
(“PROSPECTIVE RESOURES”)

Basins per Category
Category I
Category II
Category III
Category I: (1) Assam Shelf, (2) Assam-
Arakan Fold Belt, (3) Cambay, (4) Cauvery,
(5) Rajasthan, (6) Mumbai and (7) Krishna-
Godavari
Category II: (1) Andaman, (2) Mahanadi, (3)
Kutch, (4) Saurashtra and (5) Vindhyan
Basins, namely Saurashtra and Vindhyan
are now into Category II for reported
discoveries
Category III: (1) Kerala-Konkan, (2) Bengal-
Purnea, 3) Himalayan Foreland, (4) Ganga-
Punjab, (5) Karewa, (6) Spiti-Zanskar, (7)
Narmada, (8) Satpura-SouthRewa-Damodar,
(9) Deccan Syneclise, (10) Bhima-Kaladgi,
(11) Bastar, (12) Chattisgarh, (13) Pranhita-
Godavari and (14) Cuddapah

Basin Areas
Category I
Category II
Category III
Basins are mapped using latest GIS
application and coordinate reference
system
Boundaries are remapped, deepwater
areas added to respective basins, new
areas identified and included
Shallow water is mapped between 0 to
400m isobath and deepwater between
400m and Exclusive Economic Zone
(“EEZ”)
Total area: 3.36 million sq km
Onland and Shallow water: 2.04 million
sq km (1.63 + 0.41)
Deepwater: 1.32 million sq km

Hydrocarbon Resource Reassessment
8 OALP Blocks-on-Offer (Bid Round I) | GoI Event at Hyderabad | March 2018
Overview of the Study
Carried out reassessment for all 26 basins
Assessment done for conventional reservoirs only
Reviewed by international subject-experts and Indian basin-experts
Assessed 13 basins with adequate datasets through Petroleum System
Modeling
9 basins (Assam Shelf, Cambay, Rajasthan, Mumbai, KG, Cauvery,
Mahanadi, Bengal-Purnea and Kerala-Konkan) : entire area
4 basins (Assam Arakan, Andaman, Kutch and Saurashtra) : part area
Identified a total of 177 Plays
87 in Tertiary, 53 in Mesozoic and 37 Pre-Mesozoic
Indentified new plays
Assessed Mesozoic reservoirs in 14 basins
Basement fractures in many new discoveries

Resource Reassessment Results
Current assessment done across onland, shallow water and
deepwater
Inplace Reassessed: 41,872 MMTOE (315 BBBLOE)
Discovered: 12,076 MMTOE ( 85 BBBLOE)
Undiscovered: 29,796 MMTOE (230 BBBLOE)
Last assessment done in 1995-96 for 15 sedimentary basins :
Inplace Assessed: 28,085 MMTOE (210 BBBLOE)
Increase of total hydrocarbon estimate: 49.1%
Reassessment done at Play and Segment levels
Built a complete geoscientific database along with a number
of easy-to-use subsurface models, maps and reports
