Effective two-way communication and data flow between rig and office is essential to optimise decision making in offshore operations. Traditionally, during drilling operations, engineering, geological and formation evaluation while drilling (FEWD) data was only available at the Operator's office via morning and afternoon reports, email, shared folders and telephone. Information technology has now evolved to a stage where office-based geologists and engineers can monitor and evaluate wellsite data in real time using the Internet and any standard web browser. This enables domain experts to provide more effective support to the wellsite staff especially when critical decisions are to be made in a timely manner.
This paper describes how modern information technology such as InterACT (Formerly called InterACT Web Witness: or IWW) facilitates collaborative work in real-time on data being acquired from remote drilling wellsites. The availability of data real-time does create a paradigm shift in the way the asset team and contractors utilize data for early decisions. Challenges, benefits, and lessons learnt on the implementation and application of this technology are highlighted through examples where this technology was used namely: Echo/Yodel development drilling campaign (Woodside Energy Ltd.) for Geosteering Decisions and Melville-1 exploration well (Bass Strait Oil Company Ltd) for monitoring drilling, FEWD and wireline logging.
Experiences from these two projects gained by Schlumberger can be utilized by other companies to put in place a data flow model incorporating real time data.
Drilling for hydrocarbons and minerals often takes place in remote areas. While the operation takes place in the remote location, much of the planning, expertise and decision-making authority is located either in a town office or distributed amongst geographically spread out towns/cities and even operating companies. Data from the remote rig, whether it be land or offshore traditionally has been either faxed to town or communicated over phone. With the advent of higher speed point-to-point data connections, data was sent via e-mail, FTP'd or dropped into a shared folder. This form of communication was usually point-to-point and some cases, point-to-many.4 With the availability of higher speed links and the internet, technology has evolved such that data now can be made available to centrally located servers and distributed to all stakeholders wherever they may be, from remote locations in real-time, without the need of specialized software installation. InterACT© is one such system where data is delivered real time and provides a platform for Data Collaboration.
