Calculation of Inflow Performance Relationship (IPR) using Python

IPyR

Overview

This project descibes how to obtain max flow rate (defined as q_max: NUMERIC (float | int)) using several equations.

Language Features

Since this repository was created, Python 3.8.10 is used in this project.

Program Features

• Calculate the q_max based on relations of variables
  • Reservoir pressure (p_res: NUMERIC (float | int))
  • Wellbore pressure (p: NUMERIC (float | int))^[1]
  • Flow rate at current wellbore pressure (q: NUMERIC (float | int))^[1]
• Illustrate extensions of production data for graphic and charting purposes

^[1] Notice that p and q are combined in single dictionary defined as Dict[NUMERIC (float | int), NUMERIC (float | int)]. For instance, for single data of q and p, it will be defined as data = { "p": NUMERIC, "q": NUMERIC }.
