Trajectory design in time

Shift fault interpretation and extract seismic amplitude

An included workflow creates surfaces from fault interpretation, that can interactively be moved forwards and backwards, and displayed with amplitudes extracted from seismic volumes. This allows the user to easily design well paths in time domain that run parallel the original fault and remain at a specific safe drilling distance from the fault.

Plug-in Overview

This plug-in enables users to design a well trajectory in time domain using three different modes:

• Interactive
• Optimized
• Best fit

A variety of time domain relation can be applied including as average velocity, near well checkshot or polynomial function. Tools are also included to shift fault interpretation laterally, display seismic amplitudes on shifted fault, and rotate/translate polygons.

Specifications

• Interactive Trajectory design in time
• Apply different types of time depth relationships
• Apply different criteria to design a trajectory (DLS, max inclination)
• Use Point Sets and/or Polygons as targets
• Define best fit well for a well head and targets
• Calculate all the possible well paths based on all well heads and targets
• Create a simple report based for each calculated well
• Snap a point during design
• Insert a new point while designing
• Move fault plane in a seismic cube laterally
• Reset shifted fault plane to the original location
• Includes tool for manipulating the polygons

Features

In interactive mode, a well trajectory will be calculated with limits of DLS and maximum inclination. Using the best fit method, well head locations, and point sets/polygons (drilling targets) will additionally restrict the calculation area. Finally, in optimized method, all possible well paths will be calculated and saved. Different time depth relationships can be applied for calculations.
