Case study: creat<strong>in</strong>g advantage <strong>in</strong> Petrel with UDMD<br />
Objectives: <strong>Depth</strong> map at H3 (target) + GRV expectation curve at H3<br />
(target) + P10, P50, P90 depth cases<br />
Time Interpretations <strong>in</strong> Petrel<br />
Input<br />
Horizon H1<br />
Horizon H2<br />
Horizon H3<br />
Target<br />
• 3 time <strong>in</strong>terpreted horizons (H1, H2, H3)<br />
• Set of depth markers at each horizon<br />
• V0+KZ <strong>in</strong>terval velocity laws between each horizon<br />
• Velocity law parameters:<br />
H1: V0 = 2050 m/s; K = 0,21<br />
H2: V0 = 2050 m/s; K = 0,22<br />
H3: V0 = 2050 m/s; K = 0,30<br />
• Time pick<strong>in</strong>g uncerta<strong>in</strong>ty (1 sigma):<br />
H1 = +/- 2 ms<br />
H2 = +/- 2 ms<br />
H3 = +/- 4 ms<br />
• Local velocity residuals (variogram):<br />
H1: sill = 20 m²/s²; range X= 500m; range Y= 1000m<br />
H2: sill = 20 m²/s²; range X= 500m; range Y= 1000m<br />
H3: sill = 100 m²/s²; range X= 500m; range Y= 1000m<br />
