Automatisert Brønnkonstruksjon

Offentlig prosjektsammendrag

This project is a continuation of the ‘’Demonstration of Automatic Drilling Process Control’’ project. A new smart auto ROP module, high speed telemetry, optimization of configuration data, and an automatic connection functionality will be demonstrated fully integrated to the NOV Drilling Control System through an open application (NOVOS) on the Johan Sverdrup drilling platform. All new elements are merged and contribute in the demonstration of multiple technologies required for an autonomous drilling sequence. By combining modelling and control of key machinery, DrillTronics helps the drillers to avoid critical situations that might compromise wellbore stability and lead to economic loss or safety hazards. The new smart ROP application improve efficiency in drilling while still maintain the control of these hazards. This module continuously adjusting the WOB, top-drive RPM and flow-rate according to the current formation properties and wellbore behaviour to: Assure ability to transport cuttings, reduce risk of drill-string vibration and to avoid buckling or exceeding the geo-pressure margins. We will interface to data providers of along-string measurements with high speed telemetry to increase visibility by communicating situational awareness information to the driller. The system will show measured data compared with calculated data for pressure and temperature in the well. We will ease the use by interfacing the system to new digital platforms and get automated input to system calculation modules. DrillTronics is interfaced to MHWirth drilling machinery and has been used on several wells. In this project the interface to NOV drilling machinery is implemented through the NOVOS application and demonstrating the ability for different 3rd part software applications to contribute to machine controls in drilling. The technology will reduce the total drilling time for wells and reduce the drilling process's Co2 contribution per produced barrel.
