Objective
The aim of the Project is to demonstrate that reservoir monitoring can be done efficiently and reliably over any size oil field and over the whole life of the field. Such a system will allow oil companies to improve reservoir control, to enhance recovery and to reduce production cost and risk.
The three main objectives of the project are:
1. To reduce the cost of the system, thereby making it attractive to install in all reservoirs where it is possible to monitor the fluid movement.
2. To demonstrate that this technology works at water depths down to 1.500 meters.
3. To demonstrate reliability fully adequate for operation during 10 years.
This demonstration will help implementing reservoir monitoring by making it technically and economically feasible to install in a large number of both new and old oil fields.
European increase in recoverable hydrocarbon reserves is estimated to 528 million TOE over 20 years.
The Project aims to demonstrate Reservoir Monitoring as a feasible tool for enhanced oil recovery from producing reservoirs. The innovative parts in this Project are several:
* Permanently installed seismic receivers at the seabed ensures repeatable data acquisition over the lifetime of the reservoir. This repeatability is crucial to obtain subsurface images clear enough to detect unswept pools of hydrocarbons on the reservoirs.
* Permanently installed seismic receivers can receive data from all angles and distances and will handle subsurface differences associated with azimuth and offset better than conventional towed marine streamers.
* Electronics and receivers are to a large extent integrated within the cable system. This integration provides for protection and hence reliability as well as reduction of number of connectors. Subsea connectors are one of the main problem areas for reliability and operational lifetime.
* Installation of highly sensitive seismic acquisition electronics at water depths down to 1500 meters are innovative by itself. The Project will adapt marine streamer electronics suitable to deep water installations.
* Cable and electronics manufacturing will be cheaper than what is possible with present technology. This cost reduction is required to achieve reservoir monitoring as a standard tool for enhanced oil recovery.
The technology of this Project is operated in the marine deep sea environment, installed over producing reservoirs to monitor oil depletion and to increase the total recovery from the reservoir. 4D seismic, where elapsed time is the 4th component together with spatial dimensions, is becoming increasingly more popular in terms of reservoir monitoring. This Project will provide the oil companies with a tool capable of performing reservoir monitoring more accurately than what is achievable with conventional towed marine streamer acquisition. The repeatability obtained with permanent installation of the receivers can not bemet with towed streamers.
This Project also aims at bringing cost of equipment and installation down to a level where it is comparable with a repeated number of towed streamer data acquisitions. Over a standard size reservoir the new technology demonstrated in this Project will be cost comparative between 5 to 10 surveys. When the added repeatability and data quality are taken into account, permanent installation of receivers will prove beneficial over conventional technology at an even earlier stage. Given a typical reservoir lifetime of 10 to 20 years, installation of permanent receivers at the seabed will be the optimum solution for reservoir monitoring. The increase in recoverable hydrocarbon reserves in Europe is estimated at 528 million TOE over 20 years.
