Well Temperature Distribution
Pwptemp is a small LGPL licensed library for easy calculation of the temperature distribution along the well. Features are added as they are needed; suggestions and contributions of all kinds are very welcome.
To catch up on the latest development and features, see the changelog.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
- Wheels for Python from PyPI
pip install pwptemp
- Source code from github
git clone https://github.com/pro-well-plan/pwptemp
The code is compound different files as follows:
Wellpath.py â–· contains a function to define the MD, and TVD values from the wellpath.
Input.py â–· creates a class (WellTemperature) to have access to the parameters of the case.
InitCond.py â–· defines the initial and boundary conditions.
HeatCoefficients.py â–· contains a function to calculate the coefficients for the heat tranfer equations that will be used.
LinearSystem.py â–· contains a function to generate the entire temperature profile.
Graph.py â–· contains a function to plot Tfm, Ta(bottom), Ta(outlet) vs time. And another function to plot the temperature profile.
Main.py â–· contains a function to determine the temperature profile at any time and another function to calculate for the stabilization time.
Around 43 data inputs (such as depths, diameters, temperatures, densities and operation parameters) are involved in pwptemp. However default values are provided in order to only change the parameters that the user wants to load.
Pwptemp allows users to count with heat data for different sections of a well and also to calculate the temperature values at certain circulation times (drilling operation).
Temperature of the fluid inside the Drill String (Tdsi) Temperature of the Drill String Wall (Tds) Temperature of the fluid inside the Annular (Ta) Temperature of the Casing (Tcsg) Temperature of the Riser (Tr) Temperature of the Surrounding Space (Tsr) Temperature of the Formation (Tfm)
Note 1: Above seabed, casing section is replaced with the riser and surrounding space would be sea water.
Note 2: Beyond the 'undisturbed formation zone' the temperature keeps constant (Tfm).
