"1) They simply drilled in wrong part of the basement with poor fracture connectivity."
WD was not first choice if HUR were paying. Only drilled first as Spirit paying - so gauges inplace to confirm pressure connectivity between Lincoln Crestal and Warwick Crestal. This was not risked properly as obvious now in hindsight, deep reservoir not fractured enough to be productive at this location, even though oil reservoir. Need sufficient fracture/ft along well to get well cleaned-up when drilling with losses current practice.
"2) Warwick and Lincoln not actually connected. Therefore overall reserves likely less."
This does not matter - producers will be needed in Warwick & Lincoln - distances are so great. Tie-ing back Lincoln Crestal next year to AM would give this information within months, but not definitively. If separate maybe recovery would be higher. Under Operation Interruption - who cares!
"3) The models are not as accurate as well all hoped."
Think they are - but best rock at crest, weathered zones + fractures. Warwick & Lincoln Crestal wells will prove this. If WD had worked - we all could have gone on holiday without any issues left to resolve. Based on GWA CPR - Warwick Crestal looks more fractured than Lincoln Crestal so should have been drilled next . Why are HE not drilling longer laterals to ensure more productive producers - this has not been discussed on any BB, nor by HE. If drilling more fractured areas - resources post well should increase, eg Warwick Crestal.
"4) Drilling a horizontal well without a prior vertical well was a mistake."
Fractures interpreted on seismic so not easily converted accurately to Depth as are measured in Time. Near Vertical wells should drill some fractures which can then be re-drilled when drilling the horizontal wellbore - ensuing optimal depth. Dr R-T experimentation may have delivered two poor producers now - its may be not easily to point the operations in a different direction. A new well on Halifax may need to be tested through cemented casing/liner - if that does not work - you can always drill on and test that open-hole. Be interesting how much of the past operations will be discussed on 9th or 11th. Most likely it will all be just rocks.
