PHASE - Reservoir simulationAims of Phase IV:

- To carry out a research analysis on a particular aspect of oil field development.

- To engage in a reservoir simulation practical activity including: problem definition; method selection; data gathering; preparation of a design solution with calculations, data sheets, sketches and drawings; checking, review and criticism of results.

Part A:

Research: The research will be focus on gas and water coning during production and strategies used to control water/gas coning in field development. You also will review principles of reservoir simulation, assumptions made and uncertainties.

Your research has to include a discussion on the following parts:

- Physical principles in which reservoir simulation is based on.
- Required information to build a reservoir simulation model, including a discussion of effect of possible uncertainties and assumptions made.
- Explain Recovery Methods and Gas and Water conning.
- Principles and strategies used during field development to control and/or manage Gas and Water conning.

Note: You might find useful to use some cases studies to support your discussion.

Part B:

Simulation: In this part you will apply what you learn in Part A in a practical case.

"Field development strategy of an oilfield using Petrel Reservoir Engineering (RE)"

"Student will be provided with data to import and they have to follow steps learned in workshops to make a 3D model:

- Calculate OOIP.

- Follow steps to make a reservoir engineering model including an active aquifer.

- Analyse production of existing wells with natural depletion for 20 years. Identify water breakthrough and discuss alternatives to delay and/or minimize water production.

- Calculate the critical rate for water coning for your given case.

- Design and locate new wells and re-design existing wells so that you can delay water conning.

- Explain how mobility ratio affects water conning, what options do you have to modify mobility ratio?.

- Propose 3 development cases and support your plan. Compare proposed scenarios technical and economical. Assume cost of wells and any treatment.
