“…Due to their application, marine risers are usually insulated to resist seabed temperatures. Different researchers have presented different studies on monitoring of marine risers, such as fatigue monitoring using shape-sensing devices [53,[66][67][68][69], fibre-optic monitoring [54,[70][71][72][73], intelligent systems [74][75][76], optical sensing [51,[77][78][79][80][81], Riser Integrity Management (RIM) [82,83], flexible pipe integrity assurance [36,69,84], pipeline condition monitoring [85][86][87], vibration monitoring for armour failure [63,67,68,86], pipeline surveillance monitoring [88], and leak detection systems [76,86,[89][90][91].…”

The increasing energy demand has led to more explorations in the oil and gas industry. To achieve this, marine risers and pipelines are used to convey fluid and other resources to meet the increasing demand. In recent years, hybrid flexible composite risers have become more adaptable. Flexible risers have already proven to be a popular riser solution for various floating production systems in shallow to deepwater in many parts of the world due to their good dynamic behaviour and dependability. The hybrid flexible composite riser is made up of numerous layers of plastics, flexible pipes, composites, and steel. Some innovative monitoring methods, such as Fiber Optics Bragg Gratings (FBG), are based on a clamped composite structure with embedded optical fibre. This study presents characteristics of the monitoring techniques of composite flexible riser technology. The advantages of the monitoring techniques include aiding composite riser measurements, recording data from riser deformation, improving integrity assurance, and dependability of design from stable readings. It also proposes some design approaches as guidelines that are advised, with some policy implications.

Summary Aera Energy LLC was formed in 1997 to be a low-cost operator and producer in California. However, the low oil prices from 1998 to 1999 forced an examination of all operations in the office and in the field. Cutting costs, improving timekeeping, or reducing the scale of operations would not be sufficient without a step-change gain in efficiency. This step-change gain came from the use of principles and concepts developed in the automobile and construction industries. Toyota's twin pillars of just-in-time production and the ability of anyone to stop production rather than pass on defects, coupled with level-loading of work processes and reducing waste, were introduced. Toyota's principles were enhanced by the addition of “Last Planner” concepts developed for the construction industry. When both were implemented for reservoir-characterization and reservoir-development work, significant process improvements resulted. The resulting improvements are now being used throughout the company to improve quality by removing waste and reducing errors, to measure processes, and to improve cycle times. The unconventional diatomite reservoirs and oil-sand reservoirs at the giant Belridge field produce 65,000 BOPD from 5,300 producing wells and 2,100 injection wells. The many drilling, completion, and workover rigs have a constant appetite for new wells. To maintain production and cost targets, everything in the office has to run reliably and efficiently at all times, as well as support field operations. Different aspects of Toyota's principles and “Lean Manufacturing” are illustrated by use of project work for reservoir characterization, day-to-day reservoir surveillance, and the development work needed to plan and schedule new wells. The processes and projects typically have multiple customers and suppliers—internal and external. All involved, including knowledge workers (those who think for a living), need to work as a single system with a manufacturing mentality and to strive for continuous improvement. Customers of the knowledge work supplied by the geoscientists and reservoir engineers have benefited greatly from the introduction of the lean processes and the resulting smoother and more-effective workflows. In 2011, the Development Team's lean activities were recognized by the Association for Manufacturing Excellence, and the team received the Manufacturing Excellence Award that recognizes “continuous improvement, best practices, creativity, and innovation.” The oil industry has a reputation of being slow to adopt new technologies and techniques. However, a Lean Manufacturing mentality introduces new ideas and ways of performing knowledge work that may change this paradigm while contributing to the bottom line with reduced cycle time and improved quality. A significant additional benefit is that geoscience and engineering professionals can spend more time doing creative work and less time fixing problems or reacting to system upsets—as they simultaneously reduce waste. However, to realize all these benefits and the step changes they provide, a thorough understanding of Toyota's principles and a Lean Manufacturing mentality are essential.

In subsea applications, our Intelligent Casing-Intelligent Formation Telemetry (ICIFT) Systems focus on using fiber optic sensing methods for lifetime monitoring of a well and its reservoir. The production casing and/or formation/cement outside the casing are instrumented with fiber optic cables that require continuity connections with other fiber optic cables that exit the wellhead. Two new technology tools are needed to join two fiber optic cables downhole laterally across an annulus. One is a "lateral" fiber optic (FO) pressure balance oil filled (PBOF) wet-mateable connector. The other tool needed and the one addressed in this articel is one that can align two FO cables with millimeter precision for connection laterally across an annulus. For that purpose, a downhole autonomous robot rendezvous tool is designed that can align two FO cables at a lateral crossover point with millimeter precision; two prototypes are constructed and tested. The setting of this research is to bring fiber optic cables through the wellhead in the annulus outside the production tubing, down through the production packer, and crossing laterally in the annulus over to the production casing. The autonomous robot rendezvous tool developed with prototypes and tested uses two subassembly designs: a tubing subassembly design and a casing subassembly design. The objective of the autonomous robot rendezvous tool is to align the two subassemblies with millimeter accuracy in two dimensions (i.e., in depth direction and in angular rotational direction). The designs of the two subassemblies are developed for popular subsea 7" OD production tubing and 9 5/8" OD production casing and for a completion fluids-based annulus environment (e.g., brine, water, and diesel). Test results of the two prototypes provide 5 mm "ballpark" accuracy for rendezvous alignment in the depth direction and 2 mm accuracy for rendezvous alignment in the angular direction. The development of the autonomous robot rendezvous tool is one step in the direction of making the reservoir intelligent outside the production casing via all means of distributive fiber optic sensing methods without the need for power and electronics downhole during the lifetime of well.
