Of some interest to the CTP faithful, the following is lifted from today's TSV ann re "tight gas" plays. We may be referencing "Silt Stone" rather than so called tight sands but our depths are considerably shallower and the technology is growing by the day. Do you have comment on tight sands vs Siltstone? We are a long way from conclusions re commerciality of this play

Tight gas plays generally
? There is growing recognition world‐wide of the value of tight gas plays, comprising tight sands, coal bed methane and shale gas. The coal bed methane boom is well known in eastern Australia. In the USA the boom in shale gas and tight sands is even larger.
? The advent of horizontal wells and improved fraccing and completion techniques has dramatically improved the economics of these plays, assisted by generally higher energy prices. The refinement of these techniques has come a long way, even in recent years.
? Once the correct drilling and completion techniques for a play are established, they can be replicated over hundreds or thousands of well locations unlocking a large known gas resource. The size of the resource is usually very large because the gas is trapped (tight) throughout the whole formation, whereas conventional plays rely upon less frequent and less predictable traps of mobilised (free flowing) gas.
? Some of the largest oil and gas companies in the world have recently paid billions of dollars to buy into tight gas plays in the USA and eastern Australia.
? It is now estimated that there is more than 1,000 TCF of potential gas production from tight gas plays the USA, which currently contribute almost 50% of the total US domestic gas market of 19.4 TCF per annum. Tight gas has reversed a long decline in US domestic reserves of hydrocarbons.
