Surface facilities are where reservoir production becomes revenue. A field can be technically excellent in the subsurface and still fail commercially if the processing plant cannot handle the water cut it eventually produces, cannot meet the salt specification when formation water breaks through, or cannot compress the associated gas when reservoir pressure falls. The facility is a fixed asset sized on assumptions about a well stream that is guaranteed to change.

The core physics is straightforward: gravity separates phases of different density, given enough residence time and a quiet enough environment. Everything else in the facility exists because that simple mechanism is disturbed. Emulsions form because shear at the choke and in the flowline disperses water into oil and natural surfactants stabilise the interface. Foam forms because gas breaks out through viscous crude. Slugs arrive because multiphase flow in a long flowline is unsteady. Salt remains in the crude because it is dissolved in water droplets too small to settle. Each of these problems has an engineering answer, and the answers interact with each other across the train.

Understanding that train as a connected system is what separates competent facilities work from unit-by-unit thinking. Changing separator pressure alters the amount of gas going to compression and the vapour pressure of the crude. Adding demulsifier upstream changes water carry-under and therefore the load on the water treatment package. Raising treating temperature meets the water specification but drives light ends out of the crude and reduces the volume sold. This course develops both the individual unit operations and the interactions that determine whether the plant as a whole performs.

By the end of this training, participants will be able to:

• Describe the complete oil processing train and the specification each stage exists to meet
• Size two phase and three phase separators for gas capacity, liquid residence time and separation efficiency
• Identify emulsion formation mechanisms and select heat, chemical, electrostatic or combined treatment
• Specify dehydration and desalting equipment to meet water content and salt content requirements
• Evaluate crude stabilisation and sweetening options to meet vapour pressure and hydrogen sulphide limits
• Determine associated gas handling requirements including compression, dehydration and conditioning
• Design produced water treatment schemes for oil-in-water specification, reinjection or disposal
• Specify storage, metering, pumping and export arrangements including custody transfer requirements
• Diagnose common processing problems including carry-over, carry-under, foaming, slugging and off-specification product
• Assess how facility performance changes as water cut, gas-oil ratio and inlet pressure evolve over field life

The course is delivered as a technical programme following the well stream through the facility from inlet to export. Each unit operation is introduced through the physical mechanism it relies on, then developed into sizing and selection practice, then examined for its operating problems and its interaction with the units around it. Process flow diagrams and field data from operating facilities are used throughout, including plants that failed to meet specification and the modifications made to correct them. Changes in feed over field life are treated as a central design consideration rather than an afterthought.

Organisations sending participants to this training will:

• Improve facility uptime and reduce off-specification production and export interruptions
• Debottleneck existing plants as water cut and gas rates rise rather than accepting deferred production
• Specify and review facility designs and modifications with better technical judgement
• Reduce chemical consumption and treating cost through better process understanding
• Improve produced water quality and reduce environmental and compliance exposure
• Strengthen the interface between subsurface forecasts and facility capacity planning

Participants will:

• Understand the complete oil processing train and the purpose of every unit within it
• Size and select the principal separation and treating equipment
• Diagnose processing problems from operating symptoms rather than by trial and error
• Anticipate how the plant will respond to changing well stream composition
• Contribute confidently to facility design reviews, modifications and debottlenecking studies
• Work effectively across the boundary between production operations and process engineering

• Production and process engineers working on oil production facilities
• Facilities and project engineers involved in design, modification or debottlenecking
• Operations engineers, plant supervisors and senior operators
• Petroleum and reservoir engineers who need to understand surface constraints
• Maintenance and integrity engineers supporting production plant
• Commissioning and start-up personnel
• Technical managers responsible for production facility performance

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
