The area of designated reservoir is $100$ acres, and the thickness of the sandstone and conglomerate water wet is $100$ ft$.$ The reservoir is divided into THREE $(3)$ consecutive layers of equal thickness. The number of grid blocks in both X and Y directions are $50$ with a cell size of $100$ ft$.$ The thickness of each cell is $100$ ft$.$ Perforate the producing zone using IMEX Simulator and field units throughout in CMG and assume default data for the data that are not provided.

$1)$ Place your wells based on your waterflooding patterns.

$2)$ Produce at the gross rate with maximum surface oil rate at $3,000$ STB liquid$/$day for total summation of wells.

$3)$ Inject with a maximum value for surface water rate at $5,000$ STB liquid$/$day for total summation of wells.

$4)$ Start the simulation on $25$th September $2023$ and use time steps of $1$ month each for $20$ years. Report Format:

Organize your work in a report detailing your findings. You must include all relevant calculation, coding, illustration, graph, or table to support your work. Refer to Appendix A for field data, Appendix B for general requirement on report, Appendix C for guidelines on discussion, conclusion and references, and Appendix D for marking scheme.

Assess the Design Analysis

Student should be able to assess the parameter involved to create the reservoir model by implementing the waterflooding technique in term of cost and design by using optimum production strategy for homogeneous system to solve the complex engineering problem using CMG software starting from $15$th August $2023.$ Student should be able to evaluate the basic cost of injection and production.

Review the Proposed Innovative Design

Student should be able to review their innovative solution to predict the incremental of oil recovery from the entire field based on proposed optimum production strategy. Student should be able to list down all the justification involve in developing a certain scenario after $15$ years.

Evaluate the Design Implementation

Student should be able to evaluate the design implementation based on their knowledge to create static model. Student should be able to place different location of sink and source wells when designing the reservoir in quick pattern grid for waterflooding pattern. The outcome of model creation using software is a static model. This part of assignment is marked based on static model validity $(15\%)$ and location of wells $(15\%).$

Appraise the Dynamic Model

Students should be able to appraise their results obtained by using suitable tools and technique and it should be corresponding and representative. The result is dynamic model and leads to highest oil production from each layer and entire field. It should be $3$D view models submitted in the report $($only $3$D model with complete$-$colored version is accepted$).$ Student should be able to use quick pattern grid mode in designing the reservoir model.

Defend the Innovative Design Solutions

Students should be able to defend their individual work in term of methods employed and results obtained. Tutor assessment will last approximately $1520$ minutes followed by a five$-$minute session.
