The work program included removal of an existing submersiblepump, calliper log and well video to determine requirements for abandonment. The pump wasremoved on February 8 th, 2011, the video was performed on February 10 th and the calliper log onFebruary 22 nd .Pump RemovalA three stage 175mm submersible pump fitted to a 25hp motor was found set on 30m of 100mmsteel column pipe. Based on motor serial numbers the equipment was likely installed new in1991. The equipment is in poor condition.Video Survey ResultsA video survey was conducted to determine the depths of significant well features, and toconfirm the well was free of foreign objects and blockages. Details of the video can be found inthe attached Table 1 and a DVD is enclosed with the original hardcopy of this report.- The hole was found open and unobstructed to 96.5m.- The video survey revealed a substantial amount of buildup on the casing as seen in Photo1. The buildup made it impossible to confirm the exact depth of the bottom of the casing,but historical records indicate a depth of 53.3 m (175’).- The primary well feature is a cavernous section which starts at 58.0 m – 60.9 m (190’ –200’). This section is shown in Photo 2 along with a scrap piece of wire which is hung upacross this feature.- A 1m section of pipe was discovered at the bottom of the well as shown in Photo 3 and4.Caliper LogA caliper log was conducted of the well to confirm the well construction and can be found inFigure 1. The log confirms a total depth of 96.5m which is similar to the 97m depth reported the
