The air team modeled 21 producers and left out the 7 injectors, so rig days and NOx run short.
A 2,380-page environmental impact assessment review, thread by thread
Draft 3 of an offshore field expansion: 19 chapters and 11 appendices from six firms, with the filing date set before the board's investment decision. Here is how two facts that broke between chapters get found, sent back and checked, by the people who own each step.
demoThe field, the firms, the people, the guidance and the figures are sample data.
- 01First reading
1,146 facts tied across the draft, and 23 of them break
Assessment coordinatorThe thread board lays the whole draft out as one strip in true page proportion, with a colored thread for each fact joining every page that states it. Of 1,146 facts, 1,118 hold, 5 differ for a stated reason and 23 break: 7 change a conclusion, 14 a number, 2 only wording. Well count and field life head the list to open first.
- 02Well count
Chapter 3 says 28 wells, and the air model ran on 21
Lead assessorThe well count is stated 8 times. The project chapter says 28: 21 producers and 7 water injectors. Chapter 9 and Appendix E model 21, because the air team counted the producers and left out the injectors. Opening the passage shows the sentence on its page. What rests on it: 1,008 rig days modeled against 1,344 planned.
- 03Field life
The carbon appendix stops at 11 years under replaced guidance
Lead assessorChapter 3 runs the field for 25 years. Appendix K stops at 11, when the contract expires, and cites a guidance revision that was replaced: the one in force says not to stop at a contract term unless an extension is ruled out. Left out are 72.90 million barrels and 35.3 million tons of downstream carbon.
- 04Send-back
Signed only after he has read each passage
Lead assessorThe coordinator drafted both findings and cannot sign her own. The lead assessor's sign button stays shut until he has opened each highlighted statement. He reads all three on well count and both on field life, then signs. Each finding goes to its firm with the chapter that controls and a reply date.
- 05Challenger's reading
On the displacement credit, the agent says it cannot judge
Environmental counselThe agent has read the draft as an opposing lawyer would: 11 lines of attack, 4 strong, 5 arguable and 2 where the law is unsettled. On the 35% displacement credit it quotes the loaded guidance and two top-court rulings, and says it cannot judge. Counsel seeks an outside opinion. Filing stays shut until she rules.
- 06With the author
The author sees his two pages, the finding and the suggested fix
Chapter author at the air consultancyHis view holds only his firm's chapters. He sees the lead assessor's finding, his own sentences on each page and the corrected text the agents suggest: 28 wells, 1,344 rig days. He can return corrected text or dispute it with a reason. The challenger's reading, the library and other firms' chapters stay closed to him.
- 07Returned
Two changes came back, both matched, and none nobody asked for
Version comparerReturned text is compared against Draft 3. Two parts are back, with two changes, and each is matched to the finding that asked for it. A change nobody asked for, such as a shortened mitigation, would stop the finding from closing until a person ruled on it. Here there are none.
- 08Fresh check
All eight statements now read 28, and he checks them again
Lead assessorThe thread is whole again: all eight statements of the well count read 28. A returned chapter does not close itself. He opens the corrected pages in the air chapter and the dispersion appendix and reads them, then decides: close the finding, or return it for a second try.
- 09Closed
One thread rejoined, 22 breaks still open
Lead assessorOn the board, well count now reads rejoined and the break count falls to 22. Field life is still with its author. The filing gates stay shut until every break is closed, each stated reason is accepted and counsel has ruled on every line of attack, so the board shows the real distance to filing.
