It is well recognized that oil and gas companies have increased the implementation of collaborative centers to improve real-time decision making. This reduces nonproductive time (NPT) and improves efficiency in oilfield operations. Emerging technologies now enable end users to receive and send intelligent commands while tools operate under downhole conditions. This not only provides the advantage of fewer trips in and out of the hole, but also the ability to control operations from an office-based environment.In the last few years, Schlumberger has increased the number of collaborative centers, known as Operation Support Centers (OSC TM ), to work closely with operators throughout the world. Surface and downhole data are currently transmitted to these centers in real-time as part of the execution phase in the drilling optimization process. While the focus of this paper is on drilling, real-time data is clearly not limited to the drilling phase and in many cases has been used for completion monitoring and control.As the implementation of these centers has continued, drilling activity increased more quickly than experts could be developed in all areas of operation and support, despite aggressive recruiting and intense training and development. As a result, experts gathering in one room to advise jointly on several simultaneous rig operations became the norm and operators who experienced it quickly embraced the OSC TM concept.Real-time centers, therefore, have become the chief venue for collaboration, data capture, sharing and training, in a way that better meets the needs of fast-growing operations. Interestingly, they have also become a focal point for better coordination of operational changes, as improved communication with tools downhole and with service personnel have facilitated reduced crew and support requirements.This paper describes the challenges faced in implementing remote drilling operations, the work processes that allow one directional driller (DD) and one measurement while drilling (MWD) engineer to oversee several rigs simultaneously, and details the necessary infrastructure, communication systems and operating results.

In addition to difficult and sometimes harsh downhole environments, the driller is also faced with a dramatic increase in the quantity and quality of information available to optimize recovery. In many of these situations, there is little or no room for error and the cost of nonproductive time (NPT) due to a poor or less informed decision can significantly increase the final cost per barrel to the consumer.Advances in cost-effective satellite communication and the application of compression technology have removed the bandwidth limitation, and Internet transfer of continuous highvolume real-time data between the offshore installation and shore-based operations is almost seamless.With the current shortage of skilled personnel, most major oil and gas companies are exploring remote Operation Support Centers to support their real-time E&P business processes. With a combination of infrastructure, technology, services and processes, these support centers are consolidating their expertise in a collaborative environment so that informed realtime decisions can be made to improve drilling processes and reduce costs.The economic justification to management and partners for investing and building support centers is clear, but it is necessary to scale the effort and capital expenditure for support centers to each specific drilling operation. This paper describes the concept of low-cost remote support centers that have been used successfully in the Gulf of Mexico, and land drilling projects on the Alaska North Slope and in northern Mexico.A successful support center must quickly turn real-time data into useful information displayed with minimum latency in a format benefiting decision makers. This depends on the skill and experience of each participating engineer and the quality of the software answer products in this surveillance environment. This paper describes advanced real-time software answer products that take raw drilling data and filter it into different rig states, automatically generating logical outputs.

As demand for sophisticated drilling technologies has grown rapidly in recent years, the implementation of collaborative centers to improve real-time decision making has become an increasingly attractive option. Emerging technologies now enable real-time transmission of data and voice communications to and from the most remote locations, making it possible to receive and send intelligent commands and respond rapidly to changing circumstances while drilling is in progress. With the proper use of these technologies, it is now possible for a single team of expert personnel to monitor and control multiple complex directional drilling operations from a single remote office. In the last few years, Schlumberger has created a growing number of collaborative centers to work closely with operators throughout the world. Currently, surface and logging data are transmitted to these centers in real time as part of the drilling optimization process, and real-time data has also been used for completion monitoring and control. Coinciding with the development of the Operations Support Centers (OSCTM) concept, drilling activity increased more quickly than experts could be developed in key areas of operation and support. In such a challenging business environment, the idea of having experts gathered in one room to advise jointly on several simultaneous rig operations has won wide acceptance with the companies which have tried it. Operations centers, therefore, have become the chief venue for collaboration, data capture, sharing and training, in a way that better meets the needs of fast-growing operations. In particular, the OSCTM concept has made it possible in many cases to reduce crew and support requirements, a significant benefit in today's tightly budgeted operations. This paper describes the challenges faced in implementing a further step in operations support center, the work process that allows one directional driller and one measurement-while-drilling engineer to control directional drilling operations at several rigs simultaneously, and details the necessary infrastructure, communication systems and operating results. It also provides an insight into the process through a recent project in northern Mexico. Introduction The use of real-time, remote operating centers has become an increasingly attractive option for companies attempting to meet the growing demand for drilling services with a limited pool of expert personnel. As rig counts have risen sharply, so has the complexity of drilling projects and the challenges of downhole environments, requiring not only new drilling technologies but also the services of personnel with the requisite training and experience to operate them effectively. Directional drillers and measurement while drilling (MWD) engineers have been stretched to the limit of their capabilities, often putting in very long hours, and still the demand for their services exceeds the supply. This paper will discuss the implementation and operation of a highly sophisticated remote operation support center. From one central location, a single team of expert drilling professionals are able not only to monitor but actually to control complex directional drilling operations at multiple remote locations. With instant access to all relevant surface and downhole data, these seasoned professionals are able to direct the drillers and crew at several locations simultaneously.
