The XactSpot MSA program assists users in determining whether significant systematic data errors are present which might cause inaccurate computed azimuth values. It evaluates error sources that may exceed the expectations of standard error models.

Correctable Error Types

Axial Biases

Large axial biases from drillstring magnetization

Cross-Axial Biases

Cross-axial magnetic biases from drill collar issues or magnetic debris

Scale Factor Errors

Cross-axial scale factor errors from magnetic particles in drilling fluid

Torsion Errors

Torsion (β) or rotational toolface misalignment

Induced Magnetization

Axial scale factor errors from induced magnetization

Reference Field

Reference field errors affecting computed values

Features

MSA Calculations

Advanced multi-station analysis algorithms evaluate input data and provide corrected survey readings. Solve for axial and cross-axial biases, scale factors, torsion, and reference field errors with configurable solver options and Bz instability reporting.

Advanced Plotting

Interactive pre and post-correction data comparison with crosshair tooltips showing uncorrected and corrected values at each station. Seven plot types including Azimuth vs MD, Inclination vs MD, combined views, G Total, B Total, Dip, and Toolface. Export plots as images or copy to clipboard.

Data Importer

Import from Excel, CSV, and text formats with flexible column mapping. Automatic column detection from headers, configurable header row position, and sensor value inversion for different tool configurations. Live data preview before import.

Well Header & Tie-On Point

Complete well information management including customer, field, rig, survey details, and tie-on point coordinates. Supports both geographic (lat/long) and projected (northing/easting) coordinate systems with automatic reference value lookups.

Coordinate Converter

Built-in coordinate conversion between geographic and projected coordinate systems. Convert between WGS 84, UTM zones, and other EPSG-defined systems. Copy results directly to and from the project header with one click.

Geomagnetic Reference Calculator

Look up geomagnetic reference values for any location and date using industry-standard coefficient files. Returns declination, grid convergence, total field strength, horizontal and vertical components, dip angle, and secular variation for accurate survey corrections.
