TIGHT GAS: Tight spots
Tight gas reservoirs exist where rock permeability is low, meaning they contain less gas than a conventional reservoir. The reservoirs are normally beneath conventional reservoirs, at depths of 3,500-4,500 metres. In conventional gas basins, pressure will naturally push the gas through the drill pipe into the well; with tight gas, this process is extremely slow. The flow of tight gas can be accelerated by subjecting the rock to a process called fractionation, by which chemicals or vibrations ...
