LCT Gravity & Magnetics Software

Create, evaluate, validate

The LCT software suite creates simple and complex potential fields models of the earth subsurface, performs forward modeling and joint inversion constrained by gravity and magnetics, seismic and well information – our specialized software will help you capitalize on your potential fields data. Developed in-house by industry-leading potential fields staff, Xcalibur Multiphysics understands the need for the integration of multiple data sources and the output of results to seismic workflow. Through the intelligent use of data-driven inversions, our focus is on generating geologically reliable solutions to complex geology problems.

The main client base for LCT software suite is large oil companies and research institutions, which means LCT software is designed to be integrated into complex exploration workflows and to answer geological questions. LCT software represents a complete package for gravity and magnetic modeling, interpretation, and data processing. These tools are available as single modules or as a combined suite of applications to provide flexible licensing options.

2D Modelling

LCT 2MOD lets you conduct 2D and 2.5D gravity and magnetic modeling with or without seismic and other constraints.

Quickly evaluate anomalous geology such as salt bodies, carbonate horizons, volcanic, or understand the depth to basement. 2MOD also models borehole gravity data. 2MOD allows for lateral and vertical varying density definition for modeling geologic cross-sections. The variable density mode adds significant capability to create high definition density distribution to 2D modeling and is the only commercially available program with this capability.

2MOD provides seamless modeling of integrated seismic, gravity, and magnetics.

3D Modelling

LCT 3MOD helps you understand the geometry of an intrusive (salt, volcanic, etc.) body as well as basin structure and stratigraphy for integration of potential fields and seismic data. 3MOD displays simultaneously the gravity and magnetic model and seismic sections and does both structural and physical property (density or magnetic susceptibility) inversions. Its joint inversion capability of gravity, gravity gradient, and magnetic data is both very fast and efficient. The 3D modeling suite also contains a fast forward gravity calculation engine from SEGY density data. Several features contained within 3MOD are the only commercially available software with these unique capabilities.

Grid Filtering

LCT GRDFFT is a complete collection of wavenumber-domain filters (transformations) using the Fast Fourier Transform (FFT). Many current exploration activities are located within the low magnetic latitude zone. Uniquely, GRDFFT implements different algorithms for low latitude magnetic Reduction-To-the-Pole (RTP). For regional studies, GRDFFT also includes the Differential RTP that allows an accurate RTP computation for a large working area.

GRDFFT additionally contains many different spatial-domain filters (transformations). This last advantage is particularly useful when explorationists want to enhance gravity and magnetic signals due to lineaments, edges, and boundaries.

Magnetic Depth Estimation

Get the right answers from our magnetic depth modeling software and understand your basement and volcanic intrusions. LCT MAGPROBE is an interactive tool for estimation and comparison of magnetic depths by multiple methods – Werner, Euler, Naudy, SPI, Phillips as well as spectral and empirical methods.

The 3DEULER tool, for the deconvolution of gridded magnetic data and automatic calculation of the depth to the magnetic source, provides you with a quick and easy way to obtain general estimates of the distribution of magnetic sources. It is especially useful when working with large data sets.

LCT DATAPRO is an interactive data processing system for line-oriented gravity and magnetic data and in particular marine (shipborne) data. DATAPRO provides tools for loading gravity and magnetic data into a database, processing the data, and interactively editing and displaying the data. Output from DATAPRO may be imported into LCT’s interactive gravity and magnetics modeling and interpretation software and other industry-standard systems such as ARCGIS. Using the latest advancements in data processing methodology, this marine-oriented processing system enables viewing, processing, systematic adjustments, and correction of data. LCT’s DATAPRO is the only commercially viable system for accurate systematic processing of marine gravity and magnetic data.

MagCUBE™. Improve Positioning Accuracy in Directional Drilling

Increase your drilling accuracy and efficiency with Xcalibur Multiphysics’s MagCUBE by providing you with a subsurface crustal magnetic field model for use in geomagnetic referencing of your drill bit.

Measurement While Drilling (MWD) uses accelerometers and magnetometers as a survey tool, and these tool readings have an associated degree of uncertainty. This error is cumulative and increases with distance as a well is drilled. In practice, wells are drilled to longer horizontal lengths for increased productivity.

Surface magnetic data is used because the magnetic azimuth of the bottom hole assembly (BHA) is inferred from the vector component measurements of the MWD survey tool. To convert the magnetic azimuth into a true azimuth, one needs the local declination angle provided by a geomagnetic reference model (and local crustal magnetic anomalies). The more accurate the reference model, the more accurate the true azimuth of the BHA.

MagCUBE has been successful in improving accuracy and reducing costs in directional drilling projects onshore and offshore around the world. This advanced technology is available globally, and exclusively, from Xcalibur Multiphysics.
