2 First, Two Brief Definitions.. The US Outer Continental Shelf (OCS) is divided into Planning Areas based on administrative boundaries o Planning Area Examples: North Atlantic, Mid-Atlantic, South Atlantic Sales are held for Planning Areas on an annual basis; Sale 40 was the first sale held along the US East Coast OCS (Mid-Atlantic, August 17, 1976) MMS (1983) 2

3 ..and Two More Planning Areas are subdivided into Protraction Areas based on geographic locations o Protraction Area Examples: Hudson Canyon, Wilmington Canyon, Baltimore Rise Protraction areas are further subdivided into 9 square mile Blocks, which are sequentially numbered within each Protraction Area (ex. Lease Number OCS-A- 0028, Hudson Canyon Block 598) MMS (2008) 3

4 Success! Not So Fast.. NEW GAS DISCOVERY IS MADE BY TEXACO OFF JERSEY'S COAST; Baltimore Canyon's Biggest Find Stimulates Fresh Speculation on Commercial Potential, 'Starting to Shape Up.' Texaco Finds More Gas Off Coast of New Jersey; Flow Tests Always Made Gas Found in Two Zones. NY Times, November 24,

5 Opposing Viewpoints Standing on the Atlantic Coast but with his thoughts straying to the Pacific, Democratic presidential contender Michael S. Dukakis on Monday denounced offshore oil drilling and called for an expanded moratorium on further drilling off the Massachusetts coast.. But though Dukakis first claimed that his position would "in effect" establish a national moratorium on further drilling, he wavered when pressed on the point during a session with reporters at the end of a Boston fish pier. "I'll get back to you on that," Dukakis said. LA Times, May 17, 1988 Governor Chris Christie: Whether it s standing against offshore drilling or liquefied natural gas facilities that would industrialize the coastline.protecting New Jersey s shore is a top priority of my Administration. Press Release, August 23,

6 Seismic Acquisition: Fact or Fiction? Scientists to Obama: Stop Controversial Sound Blasting Threatening Atlantic Whales, Fish WASHINGTON (March 5, 2015) Leading ocean scientists from the U.S. and around the world today urged President Obama to halt a planned oil and gas exploration program off the Atlantic coast involving millions of underwater sound blasts that would have significant, long-lasting and widespread impacts on the reproduction and survival of threatened whales and commercial fish populations. (Natural Resources Defense Council PR) >124,000 kilometers (77,050 miles) on/adjacent to the shelf For more information on seismic acquisition visit 6

7 US EIA Energy Use Projections (2014) Quadrillion Btu Oil and natural gas are projected to contribute >60% of US energy needs over the next 25 years 7

8 Resource Assessments Bureau of Ocean Energy Management (BOEM) Assessment (2014, Pmean) 4.72 billion barrels of oil conventionally recoverable* 37.5 trillion cubic feet of gas conventionally recoverable* Oil Comparison** o A bit more than 13% of US proved reserves (end 2013) Gas Comparison** o A bit more than 10% of US proved reserves (2013) *Data from BOEM, April 2014 **Data from US EIA 2013,

9 Quest Offshore Resources Inc. Study* Economic Benefits of Oil and Gas Development along the Atlantic OCS, Federal lease sales would: Generate 280,000 new jobs along the East Coast Require $195 billion of spending by oil and gas companies in the region Contribute $23.5 billion/year to the US economy *Prepared for the API and NOIA (2013) 9

10 The Past: US East Coast OCS Leasing US Department of the Interior OCS planning areas, circa 1979 (from the Federal Register, 1980) Sales 40, 49 (1976, 1979) Sale 59 (December 1981) Department of the Interior Administrative Changes Since 1976 USGS (United States Geological Survey) BLM (Bureau of Land Management) MMS (Minerals Management Service) BOEM (Bureau of Ocean Energy Management) BLM map of leased acreage in the Mid Atlantic OCS, Sales 40, 49, 59 (proposed area), August 1981 (from McCord, 1981) 10

11 54 Total Wells Drilled in OCS* 46 industry wells ( ); only 3 wells drilled in meters WD 5 COST (Continental Offshore Stratigraphic Test) wells drilled ( ) 3 industry wells in the Straits of Florida (OCS Sale 5, 1959) 22 additional wells and core holes by USGS and industry onshore and offshore, Virginia to Long Island Historical Drilling SE Georgia Embayment No wells drilled Blake Basin Straits of Florida Carolina Trough Bahama Platform Baltimore Canyon S. Atlantic George s Bank Mid-Atlantic 6 industry, 1 COST well in SE Georgia Embayment; no oil shows Scotian Shelf N. Atlantic 8 industry, 2 COST wells in North Atlantic; no oil shows 32 industry, 2 COST wells in Mid-Atlantic; 5 discoveries, 750 bcf, 50 mmbo/c *Data from BOEM (2015) 11

12 Milestones First Sale: 1976 (Mid-Atlantic, Sale 40); $1 billion in high bids ($4.6 billion in 2014) Largest Single Block Bid: 1981 (Sale 56, South Atlantic); $103.8 million ($266 million in 2014) by Mobil, Hess, and Marathon Largest Company or Consortium High Bids: 1981 (Sale 56, South Atlantic); $234.7 million ($602 million in 2014) by Mobil, Hess, and Marathon First Well Spud: 1978, by Exxon (Mid-Atlantic, Hudson Canyon; dry hole) Last Well Spud: 1984, by Shell, Amoco, Murphy (Mid-Atlantic; dry hole) Water Depth Record: 1984, by Shell, Amoco, Sun (Mid-Atlantic, Wilmington Canyon), 2,119 meters (6,952 feet) water depth, Discoverer Seven Seas Discoverer Seven Seas drillship, 1997 photo (from Oil and Gas Journal, December 1, 1997) Moratorium: 1984 (officially 1990) Present 12

13 First Exploration Phase ( ): Results (MMS, 2007) A Commercial Failure: What Went Wrong? Industry suffered from overoptimism Poor understanding of basic geologic risks Incorrect exploration play concepts were tested Lower 48 OCS planning area map, 1990-Present, showing drilling moratoriums supported by Presidents G.

15 The Future: What s Next In Exploration? Interest will be mainly offshore North and South Carolina, focused on the Carolina Trough Salt Basin o Drilling targets Include: Rotated Mesozoic shelf margin structures with gas clouds Mesozoic sandstones associated with salt diapirs (crest and flank amplitudes and dim spots) SE Georgia Embayment Baltimore, Lydonia, Wilmington Canyon Area Discoveries USGS IPOD Seismic Line Carolina Trough Salt Basin Georges Bank 200 km 15

16 Generalized Play Model, Carolina Trough Area NW Depth (km) USGS IPOD* Seismic Line Rotated Mesozoic Shelf Margin Salt Diapirs SE 2 Tertiary Gas Clouds? Dim Spots 2000 m 4 Cretaceous Jurassic 12 Basement Triassic? Bright Amplitudes? Salt 10 km *International Phase of Ocean Drilling 16

17 The Path Forward: A Realistic Timeline A Timeline to First Oil (assumes a 2017 start) Geophysical surveys (seismic, airborne, and satellite programs) o Acquisition: 3 6 months o Processing: months+ o Interpretation: 6 12 months+ Leasing begins: Drill site-specific environmental surveys: First wells drilled: First oil (upside success case): (assumes FPSO, no pipelines) 17
