DREAM

Strong of its expertise in the interpretation of combined down-hole and surface drilling data, Epslog has developed DREAM, a powerful software that regroup efficient algorithms, scientific techniques and visualization tools to extract valuable learning out of complex interpretation of drilling data. DREAM provides a scientific framework to objectify discussions and decision making on drilling optimization and formation properties.

Applications

• Estimate rock strength considering the drilling bit as a downhole scratcher
• Estimate the power and weight transmission efficiency between surface and downhole
• Detect vibrations and provide relationships between vibrations magnitude and drilling parameters
• Estimate the drill bit cutting efficiency
• Detect undesired events : bit wear, bit balling or cleaning issues

DREAM addresses three main challenges in order to deal with downhole and surface data

• handling very large amounts of data
• recognizing signatures of particular events that occur while drilling
• providing results that add significant value to the data and help optimize drilling operations

DREAM’s main features

• Flexible and intuitive interface used to quickly access a whole panel of tools and graphical capabilities
• Easily import and export data : binary files, ASCII, LAS, Matlab files, AVI,…
• Data preprocessing : Segmentation, resampling, optimal shift finder, manual synchronization, advanced synchronization,…
• Analysis tools : Statistical toolbox, power spectrum, spectrogram
• Advanced bit/rock interaction toolbox used to estimate the rock properties and bit characteristics
• Powerful graphical capabilities : time or depth axes, XY graphs, histogram chart, 3D axes, polar plot
