Manara

Access, measure, and control multiple reservoir drains from single wellbores or multilaterals

Manage your reservoir more efficiently to improve recovery with the Manara™ production and reservoir management system. Now you can benefit from downhole permanent monitoring and in-lateral flow control of multiple zones and compartments in real time—even in multilateral wells.

Control an unprecedented number of zones and compartments with full production information from each to enable unmatched production and reservoir management in heterogeneous or multilayered reservoirs, extended-reach developments, multilateral wells, and extreme reservoir contact (ERC) wells.

Monitor and control multiple reservoir compartments with a single line

The Manara system delivers in situ measurements of pressure, temperature, flow rate, and water cut across the formation face. All sensors are packaged in one compact station with an electric interval control valve (ICV) that has a continuous choke and is controlled from surface through a single electric line. Use stations in each compartment to maximize hydrocarbon sweep and recovery per well by suppressing unwanted gas and water. Active high-precision control of more than the usual two zones brings new completion opportunities to longer and deeper wells.

Enhance drainage without intervention operations

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 ICV setting recommendations. Data workflows embedded in the real-time acquisition and control system software streamline the data gathering and manipulation required, enabling production and reservoir engineers to make decisions in minutes instead of days or weeks. For example, unwanted gas, sand production, or water breakthrough from an individual compartment can be identified and swiftly addressed to maintain production from the remaining compartments without intervention (such as with CT or electric line).

Enable high-reliability multitrip completion installation and workovers

ESP-noise-immune, field-proven AC power delivery and bidirectional telemetry enable use of inductive couplers, eliminating hydraulic wet-mate connections. Moreover, later in the life of the well, remedial operations in the upper completion are greatly simplified. Replacement of an ESP or a safety valve, for example, can be accomplished with greater confidence because the contactless inductive coupler can be reliably disconnected and reconnected multiple times.
