It is primarily for gas-condensate reservoirs. Otherwise, can anyone direct me towards any information that will help me model it. Bear in mind I am an economist, so a very very basic model will suffice.

Appreciate it.
Ello.
I am an economist too by background so be proud of it )))
As for you task if you want to make simple prediction production profile to get revenue it depends on what stage you asset are
1. beginning
2. Plato
3. Decline

1. Exploration and wild cat drilling - production start - this one is most difficult to predict the only or i would say best way is to build material balance + well productivity
2. Plato - stable production again build material balance
3. Decline - time when you production decline due to several reasons like pressure down or water cut - the easy part the only thing you do - plot your production and make decline trend in excel
But i will advise you to build material balance model or tank model for your field as it is not difficult to do - but in this case your results will be firm and solid
in this case all you need to do is to make tank model
here is link for mbal
