The map shows the subsea depths (in feet) for the top of the reservoir unit in several wells drilled into the structure. The thickness of the reservoir is 150 ft. 1. Create a structure map for the top of the reservoir using 50 ft contour intervals. There is a fault associated with the structure. Do these in order: • Draw in the contour intervals and the fault first (note the major changes in the depths of the formation top). • Draw a simple cross-section of the reservoir along the X to X’ arbitrary line (denoted by dashed red line).  • Your cross section should show top and base of the reservoir , OWC, and fault. Keep in mind scale. 1. Determine the oil-water contact depth: • Look for the thickness of the oil column in the deepest well provided which encounters oil (Well A). • Note that the oil-water contact is a flat surface (contour with an equal depth values). • Mark the OWC on the structure map.

Question

The map shows the subsea depths (in feet) for the top of the reservoir unit in several wells drilled into the structure. The thickness of the reservoir is 150 ft.

1. Create a structure map for the top of the reservoir using 50 ft contour intervals. There is a fault associated with the structure. Do these in order:
• Draw in the contour intervals and the fault first (note the major changes in the depths of the formation top).
• Draw a simple cross-section of the reservoir along the X to X’ arbitrary line (denoted by dashed red line). 
• Your cross section should show top and base of the reservoir , OWC, and fault. Keep in mind scale.
1. Determine the oil-water contact depth:
• Look for the thickness of the oil column in the deepest well provided which encounters oil (Well A).
• Note that the oil-water contact is a flat surface (contour with an equal depth values).
• Mark the OWC on the structure map.
