Log Studio™

Seen enough geoscience software made by geoscientists?

Log Studio™ represents a completely different approach; The platform is orchestrated and written exclusively by software scientists to ensure unique and unprecedented quality in terms of architecture, scalability, maintainability, functionality and usability.

Log Studio™ is the Petroware reference implementation for WITSML and related real-time technologies. The program contains a rich set of functionality for working with digital well logs and related E&P data.

Note that the pure WITSML data access is only a tiny part of building a full-scale real-time E&P application. A client application must be able to do concurrent access across multiple object sources and propagate the data asynchronously into a thread-safe data model. Requested log curves may reside in different log sets, each measured against separate Z references. Log data may be organized in runs that possibly must be spliced live. The amount of data may be vast, and the client must be prepared to do multiple queries to complete each server request. The client program must gracefully handle unstable network connections, and should be able to operate 24/7 without interruption. Log Studio™ addresses all of these issues.

From its domain within petrophysics, geology and reservoir engineering, Log Studio™ is a research platform for:

  • Advanced software architecture and scalability
  • Real-time technology
  • Parallelism and multi-threading
  • User experience (UX) and usability analysis
  • Very large data volume management
  • Communication security through cryptography
  • Modern web-technology and 3D graphics
  • Advanced image processing
  • Software development process and project management
