Al Noor Flare Mitigation Study

Analysis of the governing scenarios for existing HP Flare System using design loads. Evaluation of options for reducing the operating pressure of the unloading separator (from 40 bar); reducing the blow down rates from major contributors by adopting slower depressuring rates in order to limit the loads and minimize impact on HP Flare system and current bottlenecks (focus on MP Separator Scrubbers and Unloading Separator); staggering some of the blow down units in order to limit the loads; combination of the above options.

Identification of number of potential mitigation options based on above analysis;

Engagement with PDO technical safety and process engineers for decision and selection of the optimum proposal for temporary mitigation measures;

Liaison with PDO process/concept and technical safety engineers to come up with acceptable options of de-pressuring rate reduction and staggered depressuring taking into consideration existing F&G coverage in ANPS; Provision of a report capturing analysis, decisions and detailed requirements for implementation.

Mabrouk Debottlenecking Process Study

The constraint analysis scope included data gathering, site visits, assessment, testing and rating of existing facility to identify the bottlenecks of the facility. These bottlenecks were further examined to narrow down the limiting element causing the limitation in the system. Prepared an implementation plan containing execution strategy with reliable costing and scheduling. The findings were discussed in the Constraint analysis report.

Saih Rawl GD Flowline and Gas Gathering Network Optimization,Detailed Engineering

Conduct a detailed review of the GD Flowline and Gas Gathering Network Optimization Study for Saih Rawi Cluster. Scope included preparation of input to Project Alignment Workshop involving VEC multi-discipline team and relevant PDO representatives, review/update of existing PipeSIM model for the 5R gas gathering system provided by PDO which included nine new future wellheads and associated flowlines.

Marmul Stage – 5 EPC & Operations, EPC

Produced water at the Marmul Polymer Plant was starting to show polymer breakthrough. It was expected that the polvmer in produced water will affect the performance of the IGF and NSF units due to increased water viscosity. To assess the viscosity impact on produced water de-oiling, PDO decided to carry out trials of the produced water treatment at the Marmul water Treatment Plant (MWTP).

The trials included performance testing of the rented IGF and NSF units with actual polymer added, employing SHF-recommended method for polvmer degradation.

VEC provided engineering, procurement and operations services.

MG Pump Relocation FEED

FEED Project scope includes installation of Condensate Separator and Ejector at Barik facility as well as relocation of existing redundant Condensate Export Pumps from MG facility to barik Facility in order to debottleneck the constraints in existing Barik Condensate export system.
