Sand intrusions reveal increased reserves

Highly permeable sand bodies injected into low permeability shales may provide additional reserves to existing discoveries and fields if properly recognized. Such sandstones, a product of postdepositional remobilisation, may also constitute exploration targets in their own right when thick and laterally continuous. Improved understanding and detection of sand injectites has – in fact – led to a recent discovery.
