Section V-527 - A Well From Which Some of the Casing Has Been Removed

A. If the casing remaining is in the upper part of the hole, the well shall be sounded to determine the amount, if any, of "cave in." That part of the hole filled with "cave in" material shall be reamed or drilled out to the original depth of the well shall be plugged and sealed with neat cement or cement slurry to a height of not less than 50 above the bottom of the casing. The casing between top of this bridge plug and a depth of 30 feet below the top of the casing shall be filled with fill material if no saline water aquifers were penetrated. A 30-foot surface plug shall be set in the upper 30 feet of the casing. If saline water aquifers were penetrated, the casing and open hole shall be completely filled from bottom up to the top of the casing with neat cement.

B. If the casing (including the screen) remaining is in the lower part of the well, the well and hole shall be completely filled with neat cement from the bottom up to or near the ground surface.
