Task: Imagine you are developing a software program to simulate reservoir behavior in an oil field. You need to write a function called calculate_pressure_drop that calculates the pressure drop across a reservoir layer based on its thickness, permeability, and flow rate.
Instructions:
calculate_pressure_drop function.Example Inputs:
Hint: You can use the following formula for pressure drop calculation:
pressure_drop = (flow_rate * viscosity * thickness) / (permeability * area)
Note: For simplicity, assume a viscosity of 1 centipoise and a reservoir area of 1 square kilometer.
Here's an example of the code and unit test:
```python import unittest
def calculatepressuredrop(thickness, permeability, flow_rate): """ Calculates the pressure drop across a reservoir layer.
Args: thickness: Thickness of the reservoir layer in meters. permeability: Permeability of the reservoir layer in millidarcies. flow_rate: Flow rate in barrels per day.
Returns: Pressure drop in bars. """
# Convert units to SI thickness = thickness * 1 # Already in meters permeability = permeability * 1e-3 * 1e-12 # millidarcies to m^2 flowrate = flowrate * 0.159 # barrels per day to m^3/s area = 1e6 # square kilometer to square meters viscosity = 1e-3 # centipoise to Pa.s
pressuredrop = (flowrate * viscosity * thickness) / (permeability * area) return pressure_drop
class TestPressureDrop(unittest.TestCase):
def testcalculatepressuredrop(self): thickness = 10 permeability = 100 flowrate = 1000 expectedpressuredrop = 1.59 self.assertEqual(calculatepressuredrop(thickness, permeability, flowrate), expectedpressure_drop)
if name == 'main': unittest.main() ```
This exercise demonstrates how to code a basic function for reservoir simulation and write a unit test to ensure its accuracy, highlighting the importance of these practices in building reliable oil & gas software solutions.
