Simple PC program calculates modified S-type well trajectory

A simple personal computer (PC) program written in Basic can quickly calculate the trajectory of a modified S-type deviated well. The program calculated the build-up angle, the measured depth, the true vertical depth of each interval, the total measured depth of the well, the end of build, and the d...

Description
Summary:A simple personal computer (PC) program written in Basic can quickly calculate the trajectory of a modified S-type deviated well. The program calculated the build-up angle, the measured depth, the true vertical depth of each interval, the total measured depth of the well, the end of build, and the drop-off point. The program can be run on any IBM-compatible computer with MS-DOS version 5 or higher and QBasic or any other Basic program that does not require the line numbers. There are several types of directional well trajectories that can be drilled to hit a target: 1. a simple type well path or build-and-hold trajectory, 2. a continuous build trajectory, 3. an S-type trajectory, or 4. a modified S-type trajectory. A simple program was published that quickly calculated the angle and measured depth of a simple directional well bore trajectory. Details concerning the program are discussed.
