The risk is very low. Key components have built-in redundancy, and failure of one sensor or board does not propagate to the rest of the system.
The “fail as is” system is rarely in a closed position. Conventional straddle systems can be deployed on wireline or tractor to plug off a failed open zone. A tubing puncher or sliding sleeve can be used to regain zone production in the unlikely case of a failed closed valve.
Heterogeneous formations produce water mostly from 1–2 high-permeability streaks. Zones producing <40% water can be identified with the Manara system and high-water-cut zones selectively closed. Flow rates, reservoir pressures, productivity index (PI), etc. are still valid. Temperature can sometimes be used as a good indicator of water (or gas) production. Fluctuations in flow or pressure can indicate oil-water flow. Deviation from the normal production condition can be identified with Avocet software platform and may be interpreted as “water production.”
Manara system was developed primarily for oil-water reservoirs. Below 30% downhole gas volume fraction (GVF), liquid flow rate measurements are within the specified accuracy. Below 10% GVF, the impact on water cut error is <3%. Manara system is not designed for gas wells with liquid production. To date, system performance has remained unaffected in wells where free gas is produced with the oil-water flow in various zones.
We have deployed six zones in a trilateral well at up to 14,000-ft MD [4,267-m MD] and five zones (with six Manara system stations) at up to 33,533 ft [10,220 m] in an extended-reach well. Simulation modeling is recommended for more than 4 zones, >15,000-ft MD [4,570-m MD], and subsea installations. Advanced system modeling capabilities are available.
Data reach the surface almost instantly, where wellbore and reservoir surveillance software facilitates understanding of flow behavior in real time and effective use and analysis of the data through clear displays and FCV setting recommendations.
Data workflows embedded in the software reduce the amount of data gathering and manipulation needed, freeing up production and reservoir engineers to manage the asset and focus on priority wells. Decisions that used to take days or weeks can now be made in hours.
