Q3. You are estimating the pay zone thickness ds of a producing reservoir at location X. Five wells A-E have been drilled in the vicinity of X. The values at well locations A to E are provided in Table 2. (20 marks) Use local averages with a search radius of 50m to derive an estimate of ds using inverse distance squared weighting with a search radius of 50m.
Table 2:
Location x [m] y [m] ds [m]
A 41.00 23.00 2.0000
B 32.00 28.00 5.0000
C 35.00 22.00 2.5000
D 28.10 30.50 4.7000
E 31.50 26.40 3.7000
X 37.00 26.00 ?
