Jim Bob Moffett - Deep Gas Play in Gulf of Mexico

Playmaker Forum 2.0 | 2014 Houston


Discovering the Missing Piece of the Gulf of Mexico Geologic Puzzle. Presented by Jim Bob Moffett at Playmaker 2.0 Forum in Houston, Texas on 23 January, 2014.

Wells drilled on Gulf of Mexico Shelf — in water depths less than 200 meters 

  • Approximately 50,000 drilled to depths less than or equal to 15,000 feet 
  • Approximately 4600 wells drilled below 15,000 feet 
  • Fourteen wells drilled below 2 5,000 feet 

Deep Gas Shelf Play 

  • Shallow waters of GOM/ onshore South Louisiana 
  • Targets sections above the salt weld 
  • Multi-100 Bcfe-1 Tcfe reserve potential 
  • Well depths range from 15,000 feet to 25,000 feet 
  • Below previous production (i.e., deeper pool concept) 
  • Near existing infrastructure which allows rapid development 

Ultra-Deep Shelf Play 

  • Offshore ± 100 feet waters of GOM 
  • Targets sections below the salt weld 
  • +1 Tcfe of reserve potential 
  • Well depths range from 25,000 feet to 35,000 feet 
  • Deeply buried structures with analogs to deepwater discoveries 
  • Near existing infrastructure; approximate 18-month lead time for production casing, trees & safety valves may be required due to increased pressures/ temperatures 

Both Deep Gas Shelf and Ultra-Deep Shelf P lays are vastly under - explored early results confirm presence of hydrocarbons at depth in GOM. 

Drilling activities to date have successfully confirmed geologic model and have indicated the potential for a major new geologic trend spanning 200 miles in the shallow waters of the GOM and onshore in the Gulf Coast area. 

Davy Jones — Major ultra-deep discovery 

Important geologic results combined with the data available from other wells are redefining the subsurface geologic landscape below 20,000 feet on the shelf of the Gulf of Mexico.

  • Discovery Well 
    • Logged high-quality Wilcox pays on large structure 
    • All of the zones were full to base 
  • Offset Well 
    • Confirmed Wilcox Sand continuity 2½ miles away 
    • Encountered Tuscaloosa Sands and Cretaceous Carbonate 
  • Commenced completion of offset well in 4Q13 – Anticipate d f low testing in 1H14
