Ann: South Erregulla Update, page-78

AJ is spot-on with the Unitization. These days its more about parallel event, ie Project economics & common sense that could b missing on some occasions (eg: Govt red tape, signing bonuses, JV Ego clash, project finance/ Debt situation, Commodity price & a raft of other variables).

U can look up on the partner disagreement at Bayu & Undan discoveries across 2 permits, Laminaria & Corallina unitisation in our own backyard. In the Exmouth, there's Enfield & Van Gogh oilfield where the 2 Entities had a data share agreement when the discoveries were made.

More recently Tortue-Guembuel (Project GTA) which is a 15 Tcf gas Development straddling Mauritania-Senegal Unitisation after BP got the 2 govt's to agree to a fast track development/ taxes/ profit share etc. Then there's Jubilee & Mahogany Deep oil development in Ghana with its JUA (joint unitisation agreemnt). Recent kerfuffle offshore Mexico at Zama oil discovery where the JV discovering the field suddenly lost a bit of their share due to the 'straddle effect' next doors. Qatar-Iran's North Dome/Pars is another one.

Plenty of case studies worldwide & is a sensitive topic on how to slice 'n dice an asset esp when Geology knows no man made Borders. If u really wanted to read the fine prints of a JUA then u could check out Kosmos's SEC 10K Annual filing from 2010 to 2019 onwards on Jubilee & Tortue. Tells u how the big boys roll. Sometimes a simple agreement restores the Balance, otherwise Tribunals or Court hearings come handy.

With regards to Oz case studies, u can look up on NOPTA, rather then put AJ under the spot. Hope this helps.
