ECLIPSE simulation

[cwmhafiz]

Hello, i'm a final year student in the process of completing my FDP project. I was given a task as a reservoir engineer. My GnG and petro dept. provided me with reservoir map, some fluid and rock properties etc. My problem is that i dont have data to input in SCAL section, currently i just imported the scal data from tutorial which for sure is wrong. I ask my lecturer abt it n he suggest to use any scal data which is similar to my formation. Anyone here have any scal data?? I really need it please. My firmation is sandstone having average permeability of 343 mD. Thanks. Any other suggestions from i guys are welcomed

Use corey curves, Swir = 0.1, Sorw = 0.15, nw = 4, no=2
State your assumptions (amongst which that this is a water wet system) and dont dwell on trying to back them up in this excercise. The FDP project is more about demonstrating how you work as a team to think through a problem and make the big decisions (ie facilities types, well types, tubing sizes etc)

Make sure you understand what that curve means and how it is relevant to a given reservoir !!!! Transition zone, saturation endpoints, wetability significance etc. Cap Curve, how much of it is relevant to your problem, shape meaning etc

Thank you so much vinomarky and shakespear for those helpful replies.. now i'm gonna read through about the corey curve and the link.

This is also good

Shakespear - I believe that stanford link relates to brine/CO2 rel perm

oops

Better yet cwmhafiz take a look at this very well put together lecture presentation which will explain the limitations of various correlation and WHEN you can use them,

In the end cwmhafiz your RelPerms in the model are not a fixed parameter which will need adjustment.

Hi... million thanks to u guys. I have one more problem. I ran the simulation and the message appeared about Rs value is incorrect unless the goc at datum depth. my field has undersaturated oil, but there is gas initially in the model. It supposed to have no gas in the beginning right? Should i untick the dissolved gas option in case definition? Sorry if this is the dumbest question, i'm still learning.

Hi,
I am a student at the university and I am currently doing my research in the enhanced oil recovery using carbon dioxide as an injection medium. I am using Schlumberger Eclipse reservoir simulation software for this purpose. I followed the tutorial number 1 exactly and got all the plots on the oil production, water injection/production and gas injection but I am want to know if I am using miscible CO2 injection, as I am not sure which gas injection I am considering, can anyone tell me how can I run the model as a miscible CO2, or what changes I have to do in the case definition section of the data manager module.
Furthermore, the tutorial already runs with one gas injection well, 08 oil production wells and 10 water injection wells. How can I change the position of the wells, as the position of the wells on the reservoir is fixed? I think I can change the position of the water injection and oil production wells in the Schedule section, in the well specification data already inputted by the tutorial, but I am not sure, which values should I consider. I want to change the position of the wells, and run different scenarios of CO2 injection so as to get the maximum amount of oil production within a prescribed amount of time by changing the position of wells.
