A Leading Oil and Gas Organization Restores Integrity to Petrophysical Workflows

The client’s petrophysical analysis workflow was breaking because systems on the Open Subsurface Data Universe (OSDU®) platform consumed well data differently.

Some systems stored well log metadata in core services, while key tools such as Techlog relied on a separate Wellbore Data Domain Management Service (DDMS) for log and trajectory data. This mismatch created data silos and disrupted the ability to process, interpret, and act on well data in time. 

Hitachi Digital Services’ company 47Lining created a unified data service that bridges the gap between OSDU core services and the Wellbore DDMS. The service ensures data consistency and availability, giving systems a more reliable way to access the same well log information.  

The solution also supports bidirectional data flow. Interpreted logs from geoscientists in Techlog can be made available to downstream systems and feed upstream processes, creating a more cohesive workflow across the petrophysical ecosystem. 

The engagement transformed a fragmented and unreliable workflow into a more cohesive process. By creating a unified access layer, Hitachi Digital Services helped restore workflow integrity and improve the movement of data across connected systems. 

• Accelerated decision-making: Geoscientists gained uninterrupted access to the data needed for interpretations and timely decisions. 

• Restored workflow integrity: A critical point of failure in data processing was removed. 

• Enabled ecosystem collaboration: Consistent data flow improved collaboration and output quality across the value chain.
