There are several Values, weight fractions,
proximities and ranges are to be found out in actually finding Gas in Place.
These include weight fraction which is obtained through proximate analysis and
the range these exist between 0.05 which is for medium to volatile bituminous
coals and 0.50 which is for sub-bituminous coals.
The measurement of porosities
of cleats is also important, the measurement of these is very difficult, and
the range of values assigned to these cleats is from 0.01 to 0.05. The default
value used for the water saturation in the cleats is 1 unless there is gaseous
content already present in them.
To get spot on calculation for the parameters
of gas-in-place of the Coalbed reservoir there are many difficulties to be
faced. These difficulties include, time consumption of the elongated process,
multiple times revision of results which have been estimated, as there are
numerous wells being drilled the information is on a rising trend as well which
is why there are gas analysis equipment
required. As these reservoirs are heterogeneous in nature and the extraction of
coal from these is always less than 100% the samples which are existing must
not be used as a representative of these reservoirs.
