Example Flow: Landing Zone Identification
This Flow demonstrates how to identify your landing zones based on the deviations and your structure grids. The Flow is structured as follows:
- PointsInput >> This brings your deviations into the Flow
- ZoneLookup >> This brings in the headers and structure grids
- LandingZoneAnalysis >> This determines the landing zone, percent in zone, feet in zone, and evaluated lateral length
- PointsOutput >> Writes the results to a new points file.
The PointsInput lets you bring your deviation surveys into the Flow. The ZoneLookup determines the current zone at every depth step associated witha deviation survey (see screenshot above). In this tool all your zones must be in the correct stratigraphic order from shallowest to deepest.
LandingZoneAnalysis does the determination on the landing zone, percent in zone, feet in zone, and evaluated lateral length. Here the user should specify the Inclination above which the landing zone will be considered. E.g., a value of 80 means the tool will only consider segments of the lateral where the inclination is greater than 80 degrees.
The PointsOutput writes out a points file with the full results. This can always be filtered down to specific landing zones as needed using a PointsSelect.
Tips and Tricks
- You will need to have already processed your deviations.
- You will need to have already calcuated your structure grids.
- A geoscience license is required.

Quick Start Module
Purpose The Quick Start module is designed to help users quickly set dozens of common parameters by selecting a handful of basic options from dropdown menus. Parameters There are three parameters that are set on a zone-by-zone basis and two parameters that are set on a full-well basis. These are as follows. Discussion The parameters are linked to what are called named_defaults in the software. These are collections of defaults that can be set through assigning a single parameter.

NMR Interpretation Module
Purpose The NMR interpretation module allows users to calculate porosity, bound and free fluids from the measure T1 and T2 distributions from NMR tools. Primary Outputs Discussion In oil and gas well logging, the $T_2$ distribution is used as a high-resolution "map" of the formation's pore system. While a standard porosity tool tells you how much fluid is there, NMR tells you where that fluid is trapped and whether it will flow.
