NITEC performed a detail field study to determine the gas storage potential of a depleted oil fluvial sand reservoir. The study included geology and petrophysics analyses to create a reservoir characterization model for a detailed reservoir simulation study. The simulation model history matched the original depletion period, matching the oil and gas rates and pressure data. The optimal development required groups of 3 horizontal wells with gas injection used to sweep the remaining oil into the center production well, ultimately increasing the reservoir pore volume available for gas storage as well as recovering additional oil volume. The initial test development wells were drilled, proving the validity of the reservoir characterization, but economic conditions tabled the project.
