SCM - Business & Contracts
By P. NorbergDue to PRM’s early-market phase it may be concluded that the focus on successful and cost effective PRM projects is as much a preparation, structural, organization and management task as being a technical task.

Finding the Right Partner
By P. NorbergTo find the right partner in the ambition to deliver a cost effective project is needless to state a vital task, but also the additional work required to be successful is as important. Development work is remaining and the buyer can chose how much it wants to do in-house and how much the supplier should be responsible for.

Strategic Contract Models
By P. NorbergThe conclusion is most likely that the future will include several contract models, but as PRM eventually grows towards maturity, it is likely that more integrated type contracts will increase, i.e. more towards BOT and BOOT type arrangements.

Alternative Business Models to Overcome Barriers to PRM
By M. A. BettThe Permanent Reservoir Monitoring (PRM) market has been heralded as arriving imminently for over ten years now and advocates amongst both the oilfield services and operator communities remain perplexed as to why it has not happened. A number of technical and geoscience barriers have been responsible for an early lack of activity, but these have now largely been overcome although large-scale and long-term evidence is still in short supply due to the minimal implementation of PRM systems. However there are clear trends in the implementation of PRM systems and the contracting and business models used and required to implement them. The current and emerging situation of implementation is reviewed and approaches to address the up-front capital and operating cost hurdle are proposed.

An Integrated Approach to PRM Planning to Reduce Cost
More LessWhile costs for Permanent Reservoir Monitoring solutions will come down in time, there is one approach that can be applied today to reduce these costs. An integrated approach to PRM planning, utilizing an operational feasibility study is a key front-end driver to reduce total PRM project costs. Assembling a multi-disciplinary team and creating a collaborative working environment are critical components for feasibility study success. A combination of an integrated and collaborative approach, multi-disciplinary team input, advantaged tools for quantifying risk, innovative and integrated fibre-optic based system design and installation solutions can be used to reduce risk and reduce cost of PRM solutions.

Successful North Sea Fibre Optic PRM Installation
Authors J. Langhammer and H. NakstadThe largest ever offshore fibre optic PRM installation was successfully finished in October 2010 at Ekofisk field in the North Sea. All the channels are working and recording seismic traces (i.e. channel status is 100%), which is a great achievement for such large seismic spread in the marine environment.

Underwater Fiber Optic Connectors for PRM Systems
More LessConnectors for underwater use are an important component of many subsea systems, they make it easier to conduct onshore or offshore testing, easier to manage cabled assemblies and facilitate ease of installation during deployment. While, certain underwater connectors are well proven with a good field history and track record, more advanced optically based PRM systems utilizing fiber optic dry-mate and wet-mate underwater connectors become an increased focus on reliability to ensure that these technologies are ready for the market. This paper reviews the processes and considerations in the specification of reliable subsea connectors for use in a PRM type system.

The Ekofisk Life of Field Seismic – An Integrated Operation
Authors H.C. Hoeber AS, C.R. Berg, S. Buizard, G. Oexnevad, R. Tommerbakke, A. Bertrand, P.G. Folstad, H. Haugvaldstad and G. JeangeotEarly in 2010 ConocoPhillips teamed up with CGGVeritas for all main elements of the seismic delivery chain for the Ekofisk Life of Field Seismic project. This paper shows how the key elements of the project from acquisition to QC to processing and geosciences are linked up and how additional value can be created through seamless integration of all project elements.

How can we Obtain High-quality Cost-effective Seismic Acquisition for Permanent Reservoir Monitoring?
By T. RekdalThe following factors may assist in obtaining improved visibility on future seismic acquisition cost as well as contribute to attract interest with acknowledged seismic service providers to compete on tenders for shooting data acquisition: - Collaboration between several field operators to ensure a high utilization of the vessel. - Long term contract with pre-determined prices (e.g. 5 years) with source vessel service providers. . A seismic service provider that can package acquisition and processing will typically also improve the turnaround time of processing, which is crucial for PRM. Accurate source positioning will also help in improving repeatability and hence improve the 4D Signal-to-Noise ratio. There is also currently significant emphasize on the source technology to improve the source signal as well as reducing its potential impact on the environment. Some of these improvements may not be easily available for an ad hoc such as rigging a supply vessel. Hence, it is reasonable to assume that the quality as well as the HSE aspects is better handled with a dedicated source vessel.

Acquisition Aspects of an Interim Life of Field Seismic Project at the Azeri-Chirag-Gunashli Field in the Caspian Sea
Authors T.R. Seaborne, D.J. Howe, W. Slopey, A. Talibov and H. AsgerovThe Chirag Azeri Reservoir Seismic Project (CARSP) is the latest phase of seismic acquisition for reservoir management on the Azeri-Chirag-Gunashli (ACG) oil field complex in the South Caspian Sea, Azerbaijan (Figure 1). This poster describes the philosophy behind a semi-permanent Life of Field Seismic (LoFS) configuration deployed over the field, the details of the equipment used, the operational challenges and the timeline of events to acquire three sets of time-lapse (4D) four component (4C) OBC surveys during 2007, 2008 and 2010. The setting and geology of the ACG complex is summarised by Robinson et al. (2010) in another poster at this workshop.

How PRM Stacks Up Against Conventional 4D
More LessPermanently installed seismic receivers are one option for carrying out a series of regularly scheduled time-lapse surveys. Compared to the competing options — streamer or redeployable OBC acquisition — a permanent installation requires a large initial investment. However, in cases where there is technical and business justification for a high survey rate, a permanent installation could result in a lower total seismic cost.

Decision Analysis Applied to Petrobras' Jubarte PRM System
More LessPetrobras, founded in 1953, has been promoting seismic campaigns offshore the Brazilian coast since the 60s decade. The seismic projects of the 60s and 70s were mainly exploratory in nature and comprised essentially 2D surveys oriented towards the identification of new exploratory prospects. In 1978, the first 3D marine seismic project took place in Cherne field, in Campos Basin. Still in the 80s the largest Campos Basin deep water oil fields were discovered with the use of 2D marine seismic (Marlim Complex, 1985-1987; Albacora Complex, 1984-1986 and Barracuda, in 1989).
