Subsea gate box
Different wells in a subsea
oil
field have different production capacities, different
production constraints and different production targets dictated by reservoir
management. Therefore, they are subject to individual management and control.
However, the cluster nature of the field,
commingling the production streams of the
individual
wells,
creates
a
strong
interdependence of the flow rates and
production pressures of the individual wells.
Thus, as the wells are producing in a network, a
change in operating conditions of one well,
affects all other wells in the cluster and
consequently the total network outcome. The
results of this interdependency is that the
production rate of the integrated system i ,
most often, considerably sub-optimal.
This project explores new facilities and system
configurations, as well as novel strategies to
achieve efficient and optimal management of the integrated system. This includes
optimization over the entire life of the field, accounting for the considerable changes
in production conditions associated with the reservoir recovery process.
In short, the challenge in the project is to optimise the recovery and revenue from an
asset by managing the interdependencies between the wells.
The project will identify and evaluate the feasibility and the implication of various
subsea systems architecture alternatives. A central element of the project is the
development of a modular and multi-functional assembly to allow easy re-routing of
well streams and a quick and easy deployment of separation and compression
capabilities to a single well, to a group of wells or to the entire cluster. The assembly
named Subsea gate box will be configured to account for all the default demands of
modern subsea process equipment, including; compactness, robustness, ease of
deployment and integration in the entire system and ease of operation.
The S bsea gate box is configur bl as a template that can accommodate individual
well modules and compartments, containing process equipment (
Figure 3
). The
process equipment may include separators, pumps, compressors, control valves and/
or flow meters, according to the characteristics of the well stream. A task in the early
phase of the project (
Figure 4
) will be to identify the leading technology in the
market that suits best to a compact and modular solution. The project deliverables
will include a description of the state-of-the-art subsea process technology,
feasibility analysis of the Subsea gate box and performance analysis of business cases
designed for both conventional and low-energy oil fields.
