About BCE

BCE’s mission is to provide our clients around the world with state-of-the-art data acquisition and analysis systems for geotechnical site investigations, which allow for better and faster diagnostics of the sub-surface. If necessary, we will customize our products to suit the requirements of our clients even better.

BCE's products and services consist of

  • Customized Geotechnical and Seismic Data Acquisition Hardware and Software
  • Customized Signal Processing and Optimal Estimation Software for Geotechnical and Seismic Data Analysis
  • Applied Seismology Consulting Services
  • Geotechnical and Seismic Data Processing and Analysis
  • Professional Seminars

Some of the innovative analytical techniques developed at BCE are outlined below:

  • First to take into account ray path refraction (Snell’s law) when processing DST (Downhole Seismic Testing) data sets for estimating interval velocities and absorption values.
  • First to correct spectral ratio absorption estimates for raypath refraction when processing DST data sets.
  • Developed the concept of Seismic Trace Characterization (STC) for assessing the quality of acquired DST data and facilitating post data analysis.
  • Developed the unique STC metric referred to as the Signal Shape Parameter (SSP). This is based on assessing and quantifying the frequency spectrum of the acquired trace.
  • First to implement full waveform and polarization analysis for processing DST data sets. 
  • First to utilize Particle Filtering (PF) as a tool for seismic signal processing.
  • Developed a unique and robust model of the seismic source wave referred to as the Amplitude Modulated Sinusoid (AMS).
  • First to incorporate Rao–Blackwellized Particle Filter, Hidden Markov Model Filter (HMMF), and Kalman Filtering (KF) for microseismic event detection.
  • First to implement an Extended KF for DST absorption estimation.
  • Developed a unique signal processing technique (principle phase decomposition) for Blind Seismic Deconvolution (BSD) and time variant BSD (BSDtv) where the source waves are modeled as AMSs and phase analysis is carried out so the reflection series is derived .
  • First to utilize KF and HMMF for processing CPTU data sets.
  • Developed a unique tomographic 2D interval velocity imaging algorithm for processing DST data sets with normal moveout.
  • Developed a unique tomographic 2D interval absorption imaging algorithm for processing DST data sets with normal moveout.
  • First to apply DST absorption analysis for obtaing estimates of in-situ soil densities.
