A Saudi Aramco facility continues to serve a vital rule in the processing and export of crude oil. This facility is one of the few facilities worldwide that is considered to be fully sufficient with different processes within its boundaries. While processing hydrocarbon throughout the day, this facility also processes utilities to serve the nearby community as well as its own oper ation. The raw water that feeds the utility process arrives from a nearby fields through the 24” supply lines. These lines provide n. the subject RO plant within the utility process with the sufficient amount of water to sustain the huge magnitude of operation.
Maintaining the constant supply out of aging hydrocarbon facilities always remains as a challenge for the operating plants. The critical nature of well-established reliable facilities create no room for error or operational outages. In order to ensure that the processing of hydrocarbons is constant, aging facilities must also ensure that the stream and processing of the supporting utilities is also meeting the operational requirements. Utility streams in plant facility may encounter several challenges especially in the ageing facility (70+ year) that might result in a shutdown and thus it can interrupt the feed. This in return would result the operation to be forced to rely on the steam reserve until the return of normal operation. In this paper, a case study will be presented on a component performance and the rectification to return the service to normal operating condition in a timely manner through the utilization of an optimized nonmetallic solution based on reinforced thermosetting resin (RTR) materials. This approach for CPVC piping systems provided the required resolution with additional benefits to the facility. RTR blinds provided better manufacturability, long term integrity, endurance to better absorb the upset condition and in-Kingdom availability.
The Precipitation Hardenable (PH) Nickel alloys N09925, N07718, N09945, N09946 and N07725 are widely used for critical downhole oil field applications such as high strength tubing hangers and completion equipment. The materials are particularly useful in High Pressure/High Temperature wells where high strength and corrosion resistance are required in H2S containing production fluids. Over the last 20 years a limited number of field failure investigations in PH Nickel alloys have been related to the presence of sufficient amounts of intergranular precipitates promoting hydrogen embrittlement, which results in brittle cracking of UNS alloys N07718 3,4 and alloy N077255 and N077166.

Cesium formate (CsFo) brines have been used as the drilling and/or completion fluids in oil and gas wells in need of high-density fluids.1,2 Multiple studies on corrosion of steels and corrosion resistance alloys (CRA) in formate environments have been reported in the literature.2-8 It was known that the formate brines could undergo significant decomposition to form hydrogen when in contact with catalytic surfaces which CRA can act as. Therefore, there have been concerns that the CRA may catalyze the decomposition of formate brines to accelerate the generation of hydrogen which in turn may embrittle certain CRAs and endanger the relevant well equipment.
Offshore oil production facilities are subject to internal corrosion, potentially leading to human and environmental risk and significant economic losses. Microbiologically influenced corrosion (MIC) and reservoir souring are important factors for corrosion-related maintenance costs in the petroleum industry.1 MIC is caused by sulfate-reducing prokaryotes (SRP), which can be Bacteria (SRB) or Archaea (SRA), with the main focus in literature being on SRB.2–5 The microorganisms most frequently reported in literature to be responsible for MIC are the SRB; Desulfovibrio, Desulfobacter, Desulfomonas, Desulfotomaculum, Desulfobacterium, Desulfobotulus, and Desulfotignum, and methanogens.2,5
