Shiranish fractures fracture porosity and unswept micro fractures Free Water Level absolute distribution across the field and management of rise rate Bypassed oil in Qamchuqa
Lower well density on flanks of the structure Crest Flanks Production concentrated on crest Water level rising faster at the crest compared to the flanks
Shiranish Fracture Map Side-track campaign on flanks N of structure Side-track wells to target zones of high fracture porosity and potential unswept micro fractures in the Shiranish 2,500m 2,500m 1:32165
Irregular free water level rise Actions: Potential for unswept zones 1. Reduce rate of field offtake 2. Manage offtake less on crest more on flanks 3. Drill horizontal wells on flanks Shiranish Qamchuqa Kometan FWL…
