Description

Abstract

Directional surveys are the measurements of inclination and azimuth throughout the well. Most directional surveys in the Gulf have measurements at 100 foot intervals. The latitude and longitude is also given at each measurement point. All surveys are referenced to grid north in the native map projection of the block containing the surface location of the survey. For some old surveys the north reference was not marked and was assumed by BOEM to be grid north. They are mapped as full 3D lines for use in maps and 3D scenes.

Purpose

Analysis for oil and gas exploration and production in the Gulf of Mexico.
