Allocation factors are the practically valuable output. A conventional simulation reports what each well produces but not which injector supplied it. Streamline simulation reports the fraction of each producer's support that came from each injector, and the fraction of each injector's water that reached each producer, which converts a field of wells into a quantified network of connections. That network is what makes rate optimisation possible: reducing injection into a well whose water is producing little oil and increasing it where the response is strong is a decision that requires knowing which is which.

Voidage replacement by pattern rather than by field is a related insight. A field balanced overall can contain patterns that are substantially over-injected and others under-injected, with pressure rising in one area and falling in another. Field level voidage replacement ratio conceals this entirely. Pattern level balance, which streamline allocation makes computable, identifies where injection is being wasted and where it is insufficient.

Channelling is where waterfloods lose most of their potential. Water finding a high permeability layer or a fracture reaches the producer quickly, produces at high water cut, and thereafter recycles through the same path without contacting additional oil. The signature is high allocation between a specific injector-producer pair combined with early breakthrough and high water cut, and identifying it well allows conformance treatment or rate change before large volumes have been recycled.

Finally, streamline methods have limitations that matter. They handle displacement dominated by convection well and processes dominated by compressibility, gravity or strong capillary effects less well. They are excellent for waterflood diagnostics and rate optimisation, and they are not a general replacement for finite difference simulation. Knowing which questions they answer well is part of using them.

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

• Explain streamline theory including pressure solution, tracing, time of flight and the one dimensional transport transformation
• Interpret streamline output including drainage volumes, irrigation volumes and swept regions
• Calculate and apply injector-producer allocation factors to establish well connectivity
• Assess flood efficiency including swept volume, bypassed oil and pattern level voidage balance
• Identify injectors and injection volumes that are not contributing to oil production
• Optimise injection rate allocation across a field for incremental oil recovery
• Identify infill drilling, injector conversion and pattern modification candidates
• Diagnose channelling, thief zones and conformance problems from streamline and production evidence
• Evaluate conformance and profile modification treatments and their expected benefit
• Integrate streamline analysis into routine waterflood surveillance and management

The training establishes streamline theory and then applies it to waterflood cases from operating fields, with participants interpreting allocation factors, identifying inefficient injection and proposing rate reallocations. The predicted benefit of each proposed change is then tested by simulation so that participants see whether their diagnosis was correct. Channelling and conformance cases are analysed from combined streamline, production and tracer evidence. Field waterflood management programmes are examined for the surveillance and optimisation practice that produced their results.

Organisations sending participants to this training will:

• Increase oil recovery from existing waterfloods through better injection allocation
• Reduce injected water volume and associated cost without losing production
• Identify and correct channelling and conformance problems earlier
• Improve infill drilling and conversion candidate selection
• Improve waterflood surveillance practice and its diagnostic value
• Extract more value from existing simulation models through streamline post-processing

Participants will:

• Interpret streamline output and translate it into operating decisions
• Quantify injector-producer connectivity in a field
• Identify wasted injection and propose defensible rate changes
• Diagnose conformance problems from combined evidence
• Contribute to waterflood optimisation with quantitative support
• Build a specialist skill applicable to the large installed base of waterflooded fields

• Reservoir engineers managing waterflooded assets
• Simulation engineers working on displacement processes
• Production engineers responsible for injection and well performance
• Surveillance and reservoir management engineers
• Development engineers evaluating infill and pattern modification
• Technical staff working on improved recovery projects
• Engineers moving into mature field and waterflood management roles

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.
