“…During the course of drilling these wells many wired pipe enabled applications and benefits were experienced. Some of these have been the subject of previous papers both from BP and other operators (Wolter et al, 2007;Olberg et al 2008, Ali et al, 2008Wolfe et al, 2009;Allen et al, 2009;Hatch et al, 2011;. Some of these benefits are quite obvious and were anticipated.…”

The first use of wired pipe in BP was in early pre-commercial field trials in seven Oklahoma wells in 2004to 2005(Reeves et al, 2006. IntelliServ commercialized its networked drillstring or wired pipe with full connectivity to 3 rd party downhole tools in early 2007.BP field trialed the commercial version of wired pipe with a comprehensive suite of BHI's Loging While Drilling (LWD) tools, Measurment while drilling (MWD) and AutoTrak rotary steerable on two Wamsutter (Wyoming) wells in 2007. These wells achieved a number of "industry firsts" including the first use of IntelliServ along string pressure measurements and the first use of real-time high resolution wellbore imaging while drilling.Since then, BP has deployed wired pipe commercially on more than 14 wells in 4 additional locations (Trinidad, North Sea, Colombia, and Deep Water Gulf of Mexico) representing a good cross section of drilling conditions and challenges (including wellbore stability, hole cleaning, BHA vibrations, formation pressure measurements in depleted zones, complex geology and challenging directional requirements). This paper is a summary of the above experiences. It includes a discussion of the challenges and solutions in area such as hardware modifications (e.g. wiring top drives, reamers, jars) deployment, logistics, reliability, pipe handling and other operational modifications, surface connectivity and dataflow to shore. The bulk of this paper discusses wired pipe enabled applications while drilling. Introduction:BP has been involved with IntelliServ since its early days (Jellison et al, 2003). Early field trials of wired pipe were conducted on BP wells in Oklahoma (Reeves et al, 2006). The objective of these trials was to test the mechanical and network reliability of the system. Attempts to use the real-time data were limited. In 2007, two wells in Wamsutter (Wyoming) were used for the "Wired Pipe enabled applications" field trial. The focus of these trials was to explore what the types of real-time applications that could be enabled by the additional data available while running wired pipe, or in others words "what can we do with wired pipe that we can't do with mud pulse". Although the Wamsutter wells themselves were not thought to be sufficiently challenging or high cost to warrant the use of wired pipe on a commercial basis, they did offer the opportunity to test a number of applications which were thought to be of significant use in other more challenging and higher cost locations (mostly offshore).

“…This kind of high-speed sensor-network functionality is becoming available through wired drillpipe, Jellison (2003) and Wolter (2007). It is a new and highly disruptive technology that is firing the imagination of control engineers to innovate solutions that currently might be regarded as science fiction.…”

“…[25]- [27]. Wire pipe technology is emerging and promises kbit/s communication capacity, [28], [29] and offers considerable advantages over transmission of electromagnetic fields through the drill pipe [30]. A common challenge of all these approaches are communication reliability and corruption of data due to noise and external disturbances on the communication system, [31], [32].…”

Moving horizon estimation provides a general method for state estimation with strong theoretical convergence properties under the critical assumption that global solutions are found to the associated nonlinear programming problem at each sampling instant. A particular benefit of the approach is due to the use of a moving window of data that is used to update the estimate at each sampling instant. This provides robustness to temporary data deficiencies such as lack of excitation and measurement noise, and the inherent robustness can be further enhanced by introducing regularization mechanisms. In this paper we study moving horizon estimation in cases when output measurements are lost or delayed, which is a common situation when digitally coded data are received over low quality communication channels or random access networks. Modifications to a basic moving horizon state estimation algorithm and conditions for exponential convergence of the estimation errors are given, and the method is illustrated by using a simulation example and experimental data from an offshore oil drilling operation.
