PORTEC

A material balance model for porous rock formations

PORTEC - a material balance model to simulate gas storage processes in porous rock formations (depleted or partly depleted hydrocarbon reservoirs, aquifer structures).

Storage facility operators are currently facing huge challenges. On the one hand they need to sell 100 per cent of available working gas volume if at all possible. On the other hand they are required to comply with operational restrictions established by authorities and need to provide evidence of non-discriminatory storage access.

Additionally, injection and withdrawal rates are not constant, but rather depend on various operational factors, whereas customers are looking for flexible storage products which they can implement profitably into their trading instruments.

As a result, software programs allowing for optimum use of each individual storage facility can contribute to more effective commercialization of underground gas storages.
