Oil and gas occur naturally. Having been
created millions of years ago by the burial of organic matter, the
oil and gas has since been held under pressure in the minute pores
of certain rocks several thousand feet beneath the earth’s
surface. The volume of porous rock holding the oil and gas is referred
to as a hydrocarbon reservoir. Above the reservoir is a layer of
cap rock which is non-porous and prevents the oil and gas from escaping
to the earth’s surface. The fact that the oil and gas has
been contained within the reservoir for such a long time is testament
that the reservoir provides reliable pressure containment. If this
were not the case, the oil and gas would have long since escaped.
Star Energy’s proposals involve replacing depleted gas reserves
that have existed safely under Albury for many thousands of years. |
