HOUSTON, Nov. 4 – Vulcan Minerals Inc., St. John’s, said part of its Bay St. George basin seismic program is designed to trace the reservoir in the Flat Bay-1 well down dip to a favorable target area in a higher-temperature regime.
A detailed temperature survey indicated that initial flowbacks with increasing oil cut after stimulation of the thick, oil-charged conglomerate topped at 120 m and more than a gross 100 m thick tapered to nil because the oil’s pour point exceeds reservoir temperature.
The company, by integrating seismic with high-resolution magnetic data, is also seeking favorable permeability-porosity zones that could be subject to the injection of heat to reduce the oil’s pour point.
Vulcan let a contract to W.L. Gore & Associates Inc. for a soil gas survey that will assist in drill target prioritization, seismic, and structural interpretation of the company’s 250,000-acre exploration area.
Vulcan also mobilized equipment from Alberta for injectivity testing at the Robinsons-1 and Red Brook-2 wells to help design the optimal hydraulic fracture stimulation of the zones previously perforated and pressure tested.
Farther north, the company’s Finnegan-1 exploratory well in the Parsons Pond area is drilling toward a projected 3,250 m in the Cambro-Ordovician Anticosti basin.
