Systems Architecture A system is an interacting combination of elements to accomplish a defined objective Presenter: John de Wardt CEng, FIMechE DE WARDT AND COMPANY
Issues with Systems Architecture in Drilling / Completion Operations • Drilling is a complex multi-disciplinary expertise • System Engineering is a well defined métier used in other industries like aerospace, defense and automotive for decades • System thinking role is to capture gains through designing optimal-systems focused on most important customer needs • System Engineering is not Project Management • An optimal Drilling System can´t simply be obtained by combining best-in class tools and products • We need it both in engineering and field operations IADC ART Workshop Vienna June 2014 Systems Architecture Presenter: John de Wardt

Functional Description • Well construction (drilling and completing oil and gas wells) is a fragmented business • No logical construct
• Well construction is a complex, highly interdependent activity which has not been modeled • It is a significant challenge to develop an architecture
• Systems architecture is the foundation of the development of drilling systems automation • Aerospace, DOD, automobiles, … IADC ART Workshop Vienna June 2014 Systems Architecture Presenter: John de Wardt
Performance Targets • 3,000 ft (920 m/day) per day overall spud to TD repeatable wells with smooth wellbore (low tortuosity / rugosity), full integrity • Long reach horizontal wells • Consistent and repeatable
• 1,500 ft per day (460 m/day) exploration wells with full data acquisition

Current Situation There is no systems architecture in well construction

What is Systems Architecture • A system is defined as a set of different elements so connected or related as to perform a unique function not performable by the elements alone. • The term 'architecture' is widely understood and used for what it is--a top-down description of the structure of the system International Council on Systems Engineering – INCOSE Systems Engineering Body of Knowledge - SEBoK IADC ART Workshop Vienna June 2014 Systems Architecture Presenter: John de Wardt

Multiple use of “Architecture” • The software architecture of a program or computing system is the structure or structures of the system which comprise: • Software components, • The externally visible properties of these components • And the relationships among them.
• Technical architecture (IT) is the formal description of an information technology system organized in a way that supports reasoning about the structural properties of the system IADC ART Workshop Vienna June 2014 Systems Architecture Presenter: John de Wardt

Problem Statement
barriers, needs, critical success factors
• Barriers • As an industry we struggle to think in systems • It could become a revolution
• Needs • System definition is fundamental to automation
• Critical success factors • Very few of us are familiar with this approach

Interaction of these interdependent systems are critical to success
Definitions we know are important • Drilling State • Knowing where “we” are is fundamental • Knowing what “we” are doing is fundamental
• Use cases • What “we” intend to do is fundamental • A list of steps to achieve a goal • Consequently who is controlling it

Way Ahead • Systems thinking will create an architecture that delivers stakeholder requirements • Issue is how will the industry perceive it and accept it
• Drilling State and Use Cases are critical • Do we inherently understand them? • Should we define standards to enable interoperability?
