Installation

You can install NodAnaPy using pip:

pip install nodanapy

Usage

Here is a quick example of how to use NodAnaPy to calculate the optimal rate of an oil well.

INPUT

import matplotlib.pyplot as plt
from nodanapy import WellNAOilR

pr = 4500 # reservoir pressure
tr = 140 + 460 # reservoir temperature
ph = 140 # wellhead pressure
th = 84 + 460 # wellhead temperature
pb = 1500 # bubble pressure

well = WellNAOilR(ph, th, pr, tr, pb)

ipr_well = well.ipr
vlp_well = well.vlp

fig, (ax_ql, ax_qg, ax_qo) = plt.subplots(3, 1)

ax_ql.set_xlabel('Ql(bbl/d)')
ax_ql.set_ylabel('Pwf(psia)')
ax_ql.plot(ipr_well.Ql, ipr_well.Pwf)
ax_ql.plot(vlp_well.Ql, vlp_well.Pwf)
    
ax_qg.set_xlabel('Qg(Mscf/d)')
ax_qg.set_ylabel('Pwf(psia)')
ax_qg.plot(ipr_well.Qg, ipr_well.Pwf)
ax_qg.plot(vlp_well.Qg, vlp_well.Pwf)
    
ax_qo.set_xlabel('Qo(bbl/d)')
ax_qo.set_ylabel('Pwf(psia)')
ax_qo.plot(ipr_well.Qo, ipr_well.Pwf)
ax_qo.plot(vlp_well.Qo, vlp_well.Pwf)

OUTPUT

Ql(bbl/d) vs Pwf(psia); Qg(Mscf/d) vs Pwf(psia); Qo(bbl/d) vs Pwf(psia)

Theory

it will be to calculate inflow performance relationship (IPR) and vertical lift performance (VLP) curves for oil and gas wells. In addition, it will be to determine the holdup liquid well.

Click to expand the theory section.

Inflow Performance Relationship (IPR)

The curve is calculated using the different correlations, for example:

• Oil
  • Vogel
  • Fetkovich
• Gas
  • LIT
  • Darcy

Vertical Lift Performance (VLP)

The curve is calculated using the different correlations, for example:

• Oil
  • Hagedorn Brown
  • Beggs and Brill
• Gas
  • Gray

Dependencies

NodAnaPy requires the following Python (=>3.12) libraries:

1. PetProPy
2. Numpy
3. Scipy
4. Pandas

pip install -r requirements.txt
