Tutorial G-01: Integrated Production model Setup

Objectives:

- Set up an integrated model for a gas and condensate field

- Generate IPR and VLP curves

- Input pipeline Data

The set up of a model in GAP consist on a series of steps:

1. Draw the layout of the system in GAP.

Using the short-cut icons showed below:

From left to right the icons are: Add Separator, Add Joint, Add link-pipe, Add Well, Add Tank

Draw the following layout:

2. Linking the icons with the corresponding file.

The Tank and Well icons should have an associated file created in MBAL and PROSPER respectively.

The Tank icon should be associated to the file created in the Tutorial M-03. (M-03.mbi)

The Well 1 icon should be associated to the file created in the Tutorial P-08 (P-08.out)

The Well 2 and Well 3 icons should be associated to the PROSPER files attached in the auxiliary

folder called: Aux_Files\day3\G-01_Well2.out and Aux_Files\day3\G-01_Well3.out

3. Generating IPR and VLP

Generate the IPR from the main menu in GAP selecting:

Generate | Generate well IPRs with PROSPER

Generate the VLPs from the main menu in GAP selecting:

Generate | Generate well VLPs with PROSPER

In the VLPs generation is very important to enter a wide range of conditions that will cover all

possible intersections of VLP and IPR.

Discuss the ranges of the different variables used.
