Semantic Framework Aligns Real-Time Drilling-Management and Control Applications

Real-time signals exchanged during drilling operations are in constant evolution, provided by multiple stakeholders that have distinct perspectives on the drilling process. To achieve improved drilling management and control, the seamless exchange of real-time drilling data, without the necessity of any human intervention to configure software applications, is desirable. The complete paper presents a drilling semantic framework that allows software solutions to achieve automatic and versatile self-configuration. However, the data-exchange performances are compatible with the requirements of high-end applications involved in the management and control of drilling operations.

Motivation

Many data providers are involved in the well-construction process. Their number and role change throughout the drilling process as a function of the different activities that are executed. A typical activity lasts between 1 day and 2 weeks, and, consequently, the constellation of real-time data providers, in the most extreme scenarios, may evolve at the same pace. Furthermore, the drilling system is not static in nature. Typically, new downhole measurement tools are used for every drillstem that is run in hole.

Either because of a different setup of data provider companies or as a result of a modification of the drilling system, the number and nature of ­real-time drilling signals that are active during the well-construction process change almost daily. For any application that needs access to such real-time data feeds, a manual reconfiguration of the system inputs is both cumbersome and a potential source of error. It, therefore, is desirable that applications can automatically and seamlessly expose, discover, and choose the signals that are relevant for the management and control of the drilling process.

In the complete paper, to illustrate how automatic discovery and interpretation of the semantics of signals can provide seamless interoperability and improve the quality of service, the authors proceed step by step through an example centered on anomaly detection and characterization. The data consumer application is a data-driven system that detects abnormal hookloads and attempts to characterize the cause of the anomaly. This synopsis will discuss the theoretical underpinnings of the authors’ approach rather than outline the example detailed in the complete paper.
