The results show that the numerical models are able to reproduce the historical °API behavior and reinforcing the practicality of predict...

.../stratigraphic closure. The field initially had a gas cap and a thin oil rim. In the early 1990’s, eleven horizontal producer wells were drilled to produce solely from the oil rim. Two additional wells were used to re-inject a portion of the produced solution gas into the gas cap. Gas injection ceased in 2001...

This can not be easily modelled within a black-oil reservoir simulator, because the process efficiency depends on gas volumes and gas molar composition that change...
