Oil and Gas companies increasingly need environments that support real time E&P business processes, by linking well site information, applications, and experts with operational managers (decision makers) in one place, where daily operational parameters are viewed, decisions are made, and decisions are acted upon. Most companies believe that making decisions in real time while leveraging global resources and infrastructure will help improve their productivity in oilfield operations, while reducing costs. Project team members are often collocated to ensure open communication and planning. However, E&P activities often take place in remote and hostile parts of the world, where it may not be possible or economical to deliver all the required resources and personnel. Global operations frequently require that operations centers be "virtualized" so the team members can be globally dispersed. Reliable and secure information flow is the key to ensuring success in the oilfield of the future. One solution to such problems is the creation of an Operations Support Center (OSC). Creating and supporting such a center presents significant challenges in process, networking, security, hardware, and software infrastructure. For example, end-to-end real-time solutions require remote connectivity and "first mile" technology. Some of the challenges have been documented elsewhere. Successful creation of an OSC requires clear definitions of the business processes to be supported and the infrastructure technologies needed to support them. The well construction process is a good example of a business process that benefits from the OSC concept. At one extreme, the contemporary well construction process is characterized by more complex wells in higher cost environments with fewer experienced people available. At the other end of the spectrum are high volume wells that are highly cost driven and have very specific and repeating processes. Overlaying this are the significant advances in IT and availability of funding for new developments. Support activities for remote operations are attracting significant attention and investment. As a result the industry is seeing revised work processes based on improved up front models, along with plans that are more integrated with the actual well construction. In addition there is rapid progress on rig automation and recognition of the value added by acting in 'real-time' on more measurements. Recently, Schlumberger and other companies have started using OSCs to improve the efficiency and effectiveness of their service operations, and have also started to bring OSCs to the marketplace. This paper discusses some of the special challenges faced in the well construction domain, with examples of how some of the challenges have been met. The goal of this paper is to illustrate an infrastructure that facilitates the remote collaborative activity. Hardware and software components have been integrated into this infrastructure and used to understand the directions for future developments. While the primary focus has been collaboration to improve the well construction process, the infrastructure can also be used for production management or other oilfield operational activities. Introduction Exploration and production companies are turning towards Operations Support Centers (OSCs) as a means of gaining advantages in operations such as drilling and production, where remote collaborative access to real time data and analysis can lead to gains in productivity and efficiency. Operators and service companies have a range of strategic business activities that may be considered as part of the digital oilfield revolution. These strategic businesses are global, sophisticated systems needing many elements of infrastructure to carry those business applications. Operating companies and associated service companies have extensive expertise in their core operating processes. Their staff personnel want to use OSCs as a resource to improve their work processes, and not as a classroom in solving information technology problems. However, the very nature of the data and processes used in these centers stresses IT capabilities. Internal or external IT service providers must address several issues to ensure that the centers support the core work processes.

AbstractNew techniques and technologies have been developed and assembled to create a global electronic data delivery framework that is robust, secure and efficient. This framework serves any data type throughout its life span-as it is acquired, processed and archived-and provides the means for it to be transmitted and intrinsically integrated into the end user's domain. Details of the data delivery framework and its overall scope will be given, followed by a number of geographically distinct, tailored applications of the technology.The advancing technology front has resulted in an explosion in data volume, of which an ever-increasing amount is digital. In the midst of this explosion, the need for the highest quality data to be efficiently and electronically delivered to its various destinations has remained a goal. The solution presented herein combines an enhanced mechanism for electronic data delivery with tools that improve data usability, storage and management. All the while the data adhere to the exploration and production (E&P) standards.This framework is being applied today to formation evaluation data, such as wireline and logging-while-drilling data. However, it will soon expand to encompass all forms of data produced within the E&P industry. As the industry rapidly assimilates advances in electronic communications to improve operations efficiency, its decision-makers are demanding drilling and formation evaluation data on their desktops in real time.This paper outlines significant contributions in the areas of data security and transmission reliability, capitalizing on established and expanding networks (Internet, intranet), data composition and management techniques, and the development of software applications to facilitate end-user data reception, handling and manipulation.
