Solutions to Exercises 239

Note that the prize for pushing for the right model could be an improve-
ment in the value of your acreage of about 4% out of 17%, or a 23%
improvement. The actual equity involved would change when the full
mapping was performed, but it is likely that the improvement will remain
roughly constant given that the two wells are indeed representative.
