Background of the TMS
The TMS is an over pressured and naturally fractured unconventional oil play. It is “on trend” with the Eagle Ford shale in Texas USA, in that it has similar depositional history and age.
Whilst still in the appraisal phase, over 80 horizontal wells have been drilled in the TMS which has helped delineate the better performing area or the core of the play. Australis operates and produces from 31 of these wells (29 net). The most recent wells have been drilled in the core of the TMS (within Australis’ acreage) in 2014. They have demonstrated consistently high oil productivity and downward trending costs.
The depositional are of the TMS is 14 million acres across southern Louisiana and Mississippi (refer to ares in blue on map below). In the early days of the TMS, operators acquired large positions speculatively on the back of then strong oil prices (pre 2015) and success in other plays. However, well performance was variable (and usually binary) depending on whether drilling occurred in or outside of the core area. The better performing wells were all drilled within the core area.
Approximately 80 wells delineated the core (i.e. within the red oval of the map below which delineates the core area) of which ~ 50 wells are within the core.
Only approximately 800,000 acres (6%) is TMS Core.
