Huge Electrostatic Coalescers for the Shaybah Field provide a sunny outlook

July 23, 2015

Frames successfully completed the fabrication of two enormous Electrostatic Coalescers for the Shaybah Oil Field GOSP 4 CPF Expansion (Gas/Oil Separation Plant) in Saudi Arabia. In 2014 Frames was awarded the design and supply of the vessels by Samsung Engineering, the Korean EPC contractor. The Electrostatic Coalescers will be used to dehydrate and desalt an additional 250,000 barrels of oil per day.


The Shaybah Oil Field is Saudi Aramco’s most remote oil field and located in the northern edge of the Rub’ Al-Khali desert. The current production of this field is about 750,000 barrels per day. The Electrostatic Coalescers, also known as Dehydrators / Desalters will be used to dehydrate and desalt an additional 250,000 barrels of oil per day at the Shaybah Field and are therefore huge in size; 49 meters long and 4.3 meters in diameter.

Local strategic partner


The internals are fabricated in-house in The Netherlands, while the fabrication of the vessels was subcontracted to Frames’ local strategic partner MIS Arabia, a renowned fabricator in The Kingdom of Saudi Arabia. From this fabrication shop the vessels are transported to the Shaybah Oil Field, which is a journey of more than 800 km through the dessert.

Milestone in relationship Saudi Aramco


Frames is a known supplier to Saudi Aramco, mostly due to its drive to help clients find solutions for their process challenges. With depleting reservoirs, more water needs to be injected in (oil)fields to maintain pressure and continue production. This will change the composition of the well stream and requires advanced solutions to ensure efficient separation. Frames is familiar with Saudi Aramco’s challenges and has been providing for many years their debottlenecking support through engineering studies, CFD analyses and process equipment.

Geert Willemse, Sales Manager at Frames Separation Technologies, says the delivery of the Electrostatic Coalescers is a new milestone in Frames’ relationship with Saudi Aramco. “Our first supply to Saudi Aramco started in 1993 with two Separator Skids for the Berri Platform. Later, many large multiphase separators followed for the Shaybah, Khurais, Safaniyah and Hawiyah fields as well as produced water treatment applications for the Shaybah, Khurais and Manifa fields. Since Electrostatic Coalescers are the last and crucial step in the crude separation train, the recent supply of also these items confirms of the confidence of Saudi Aramco in our capabilities as a world-class solution provider.”

Frames Electrostatic Coalescers


Frames proprietary Electrostatic Coalescers are 2-phase separators that utilize an electrostatic field to remove water and salts from crude oil, allowing cost-effective transport and protecting downstream processes. Frames builds on its vast experience in Coalescer engineering, enabling them to give their clients a competitive advantage when it comes to cleaning crude oil. By efficiently and effectively removing undesirable water and salts, clients are able to increase the quality of their crude oil, cut their transport costs and protect their downstream processes and equipment.
