Corva provides services to large and small operators, rig contractors and service companies. Each has slightly different needs, but all require a reliable real-time platform with customizable capabilities.

Corva is for anyone tasked with improving operational efficiency. Users include drilling engineers, superintendents, company men, real-time operations centers, rig managers, asset managers and service company field supervisors.

Setup is simple. First, provide a WITSML feed from the rig. Next, share your well and communication protocols. Finally, provide us with a user list and information about your well including BHAs, well plan, casing, and mud reports.

Corva utilizes advanced software to ensure data is streaming correctly and fully populated. Additionally, internal QA/QC checklists by trained drill-log analysts certify that streaming data is within the normal ranges and is complete per the data sent by the rig. Corva monitors the consistency and availability of the data, and alerts our operations staff to abnormal behavior. Corva is able to automatically apply gap and out-of-range filters, which remove outliers and replace bad data or null data with last-known good data.

Corva trains users to ensure each person is accessing data in a way that is valuable to him/her. Our operations team is also available via phone or chat.

Yes, you can set your own system warnings and alarms to guarantee you’re notified prior to a zone of interest or a potentially difficult drilling scenario.

Yes, individual users can customize his/her dashboards to maximize effectiveness. The default version of Corva includes some standard views that our customers have found useful.

Yes, you can view all of your data, customized dashboards, set alarms and receive notifications on your iPhone now; Android will be available in June.

Corva uses automatic rig activity and operation detection to power continuous improvement. The activity detection is based on proven algorithms which use WITSML sensor values such as weight on bit, block height and bit depth in order to automatically determine rig states such as drilling connections, rotary vs. slide drilling, and tripping. Corva calculates 38 different activity and operational states that are used to measure rig performance, or to compare against other wells, rigs, crews or drilling programs.

Corva can integrate driller manual time data such as “BOP testing,” but isn’t able to automatically determine out-of-hole function time using sensor data.

Corva displays drilling metrics provided by rig sensor systems such as Pason or Totco. In addition, Corva utilizes the data to run various algorithms in real time to analyze engineering and operational performance, such as torque-and-drag and mud motor efficiency.

Corva employs physics-based models that have been published as industry standards in drilling engineering textbooks, the Society of Petroleum Engineers’ forum and those run by our own Drilling Research Scientists. For more information, contact us at info@corva.com.

Yes, Corva is an extensible platform. That makes it easy for you to use models that have been developed internally at your organization or ones provided by a third party. We provide a robust platform to run Java, Matlab, Python, .NET, Javascript and others. More information is available on our Platform page.
