Dear Oli
Technical question that you might have a thought on.
The primary risk identified prior to drilling was the integrity of the seal. From the last announcement (which is chock full of illuminating information.....) the sandstone shale sequences in previous announcement are now sandstone/mudstone pairs. Presumably undergreat pressure and plastic (I guesse given reaming and slow drill progress) Given the estimates of reservior (large column), and they are drilling the crest (greatest pressure) - is mudstone a sufficient seal in the circumstances ?
