Task: A gas injection valve (GIV) is being used to inject gas into a well for pressure maintenance. The injection rate needs to be adjusted to maintain a reservoir pressure of 2500 psi. The current injection rate is 100,000 scf/day. Based on historical data, increasing the injection rate by 10% results in a pressure increase of 50 psi.
Instructions:
**1. Calculate the target injection rate:**
The current pressure needs to be increased by 2500 psi - current pressure. Let's assume the current pressure is 2400 psi (you'll need this information to solve the problem).
Pressure increase required: 2500 psi - 2400 psi = 100 psi
Since a 10% increase in injection rate raises the pressure by 50 psi, to achieve a 100 psi increase, we need to increase the injection rate by 20% (100 psi / 50 psi/10% = 20%).
Target injection rate: 100,000 scf/day * (1 + 20%) = 120,000 scf/day
**2. Reasoning and Calculations:**
We know that a 10% increase in injection rate corresponds to a 50 psi pressure increase. Since we need a 100 psi increase, we need to double the injection rate increase to 20%. This calculation assumes a linear relationship between injection rate and pressure change.
