Reservoir Production Strategies
Hello everyone,
I have a question please, Anyone here would like to comment on different reservoir production strategies under different scenarios?
For instance,
1- Undersaturated oil reservoir with no acquifier
2- Undersaturated oil reservoir with strong acquifier
3- Undersaturated oil reservoir with weak acquifier
- Saturated oil reservoir below bubble point with acquifier around
- Saturated oil reservoir with volumetric drive.
- Saturated Oil Reservoir with Gas Cap.
4- Gas Condensates with acquifier
5- Dry Gas reservoir with adjoining acquifier
6- Shallow gas reservoir
7- Reservoirs with edge water drive or overlying gas caps.
Please feel free to share other scenarios also with respect to conventional reservoirs.
I understand that this is kind of whole reservoir engineering management but I'd really love to know what experts have to say on these things wrt industrial experience.I'd like to know rules of thumbs and things that have been done with respect to drive mechanisms, injection strategies, NPV etc.
Thankyou,

It is very rich topic and need details for each type of the above reservoirs.
Actually, the development strategy not only depends on drive mechanism but also on many other factors like reservoir geometry, depth, petrophysical parameters....etc
For example in case of Undersaturated oil reservoir with no aquifer and anticline structure better to develop by drilling on the peripheral to be away of the expected forming secondary gas cap.
The well spacing should be calculated based on the average reservoir permeability.
Also, a seismic amplitude map should help to define the best reservoir quality points.
Re: Reservoir Production Strategies
Thankyou so much sir for your input.
If anyone has more inputs please feel free to share.
I am mostly looking for conventional sandstone reservoirs.

If you have any cross section or structure contour map we can discuss further..
Re: Reservoir Production Strategies
Hi,
Please lets discuss this one.
It has simple anti cline and syncline.

Re: Reservoir Production Strategies
Hello everyone,
Please check this contour map I have attached.
What are your views on it?
Considering its geology that its sandstone reservoir with different
compartments, green representing oil, orange representing gas and blue
representing water as color code. ( I think its just gas and water but lets consider
oil also for understanding it fully).
Black big lines are faults.
In block one we have gas and surface is smooth.Should we try to produce it by
depleting drive.
Underneath we also have an oil labelled as 5.should we first try to produce oil from
5 by natural drive,later on apply injection for pressure maintenance and
miscible gas injection to sweep oil out and later on take gas out also from
gas cap formed? oil in 5 is also in dipping part.
We have to do gravity assisted miscible gas flood then?
3 is mostly gas, and it is seperate compartment fully, so Depletion drive there?
Its also at relatively smooth surface.
4 is mostly oil, some gas at the top and acquifier underneath
bottom water drive.Water Injection followed by pressure mentance?
8- Oil, acquifier and overlaying gas.
6- All oil, seperate compartment, Water Injection?
do we inject in compartments where there is no acquifier present.is it preffered?
or pressure mentance and miscible assisted flooding will do?
10- Oil with very strong acuqiifer.
9- Oil , gas and acuqiifier. Injection , right?
13-oil,gas, aciquifier.
11-oil above with strong acquifier below which is going
steep dipping.
12-Some Gas with strong acquifier
Please add any comments that you have.Also please forgive me
for not explaining geology very well.I am working on making my geology better.
Also please comment on whereever there are anticlines and synclines, where should we produce from etc.
