Introduction

wellpathpy is a LGPL-3.0 licensed library to import well deviations in (md, inc, azi) format, calculate their TVD values using a choice of methods and return them as positional logs in (tvd, northing, easting) format.

Features

• load well deviation in (md, inc, azi) format:
  • meta data (header, rkb, dfe, rt)
  • md, incl, azi
• calculate position log survey using one of these methods:
  • minimum curvature method
  • radius of curvature method
  • tangential methods
• calculate dog-leg severity from minimum curvature
• calculate depth references using header data if available: MD, TVD, TVDSS
• return interpolated deviation in (tvd, northing, easting) format
• move surface location to (0, 0, 0) or to (kb, mE, mN)
• convert to tvdss based on kb elevation
• resample deviation on regular steps with minimum curvature only

Installation

This is work in progress

From pypi with:

pip install wellpathpy

Requirements

• numpy version 1.16.2 or greater
