TMS basin and performance context

• TMS is a Cretaceous shale play with a USGS mean estimated recoverable resource of 1.5 billion barrels and 4.6 TCF.

• Activity in the TMS halted after the 2014 oil price collapse, leaving the basin largely undeveloped despite strong core well performance.

• TMS Core wells from 2014 matched or exceeded productivity of major shale basins, with further upside from modern technology yet to be applied.
