Memorandum
To: BP Project Manager
From: Melinda Pon

Subject: Seismic Exploration Results
From the data that is given we should drill these locations, A5 (500m), C5 (1500m), A5 (1000m), and D2 (2000m). We should drill these locations because when you have lower density it means that these locations are the softest and also there is oil. We used the sound speed data that was given to us to find where there would be oil and to find where there would be low density. Using a method that was shown helped us find the locations of low density.

Your Job: As the geologists at KGS, you need to write an internal memo to your project manager, providing the essential details needed to draft the full report.
Be sure to include:
1. Information regarding the methods used to make your recommendation
2. The location or grid square(s) where you propose to drill
3. Why you propose that location
4. The depth required to drill to reach the reservoir
5. The densities and depths of the rock BP will need to drill through

1) Plot what you know
2) Fit a line as close as possible to the data
3) Use your linear fit to find the relationship between other sound speeds and densities

Part Two: Now you are ready to convert the seismic raw data to a meaningful map, which might show where oil has formed and is trapped.
Using the worksheet you just created from the relation between sound of speed and density, (Table Two), and also the seismic results from your field team, create four map cross-sections of the exploration region (one for each depth). The maps should show areas where there is dense rock (like a capping stone) and areas where the density is low (like where there is oil).
Part Three: With these cross sections of rock density, you now have enough information to make a proposal to BP about where to drill. Your project manager will write the final report to BP (likely a one-hundred page document containing detailed images of the proposed site, as well as information on optimal drilling angles, depths, speeds, type of rock and many other important details.)
