Review of problems and their solutions in the Hillsboro gas storage field
Comparatively low vertical permeability prevented sufficient thickening of the gas saturation in the Hillsboro storage reservoir to prevent water invasion into the well bores during the early part of winter withdrawals of gas. The problem was solved by perforating another interval in the well casing 5 ft below the original perforated interval and installing a production packer with a seating nipple in the 5-ft unperforated interval. The gas bubble was thickened by injecting gas into the deeper zone through the packer. By installing a blanking plug in the seating nipple thus limiting winter-time gas withdrawals to the upper perforated zone, the movement of water into the well bores is prevented. The production of loose sand with the gas from one of the wells in the Hillsboro field was terminated by treating the formation around the well bore with a resinous plastic material, Sanfix. The methanol injection systems for the wells in the Hillsboro storage field were automated to inject only the amount of methanol needed, depending upon the rate of gas flow, to prevent the formation of hydrates in the wellheads and the above ground meter runs.
