40-50 GPM. The well began to leak minor amounts of gas . <br />several weeks after its drilling. The well would serve as <br />a dewatering well for First Right section and, because of <br />its lower elevation and seam depths, could significantly <br />draw down the water in the fracture zone. <br />GE 35-88 <br />Code /TD /Surf. Elev: #1B /640' /est. 7220 <br />Depth /THK /TOC Maxwell: approx -460' (no accurate measure <br />due to lost circulation & no <br />E-log) <br />Water inflow /Elev: -460'/ 6600 <br />Water GPM (est): 50-100 GPM <br />Water levels /Elev: (E-log) -280' /6940 <br />Gas inflow /Elev: -375' /6845 <br />(base of SS. & top of Red seam) <br />REMARKS: <br />This well was located in planned pillars of the advancing <br />Second Right section on the West side of the faulted <br />workings. It is a similar flow monitoring and <br />degasification and dewatering well to GE 33-88, and it is <br />located approximately 110 feet to the South. The well <br />encountered a significant gas flow at a fracture at -275 <br />feet without the presence of water. It was extensively <br />fractured such that thereafter no cuttings were returned <br />from -295' to -640', TD. It did encounter a heavy flow of <br />water at 620-630 feet and it nearly "washed" out the hole <br />at its completion. It developed such an extensive fluid <br />communication during drilling through the fracture system <br />that foam and cuttings were coming out of GE 26-88, GE 33-88 <br />and the mine waters being pumped from the fault in Second <br />Right section. <br />E-1 <br />REMARKS: <br />This well was drilled to intersect the Second Right workings <br />at the intersection of Entry #2 and crosscut 11 (station <br />13). No appreciable water was encountered in the overburden <br />for this well, and it was completed with steel casing within <br />50 feet of the mine roof. The casing and packer were <br />dropped 20 feet during completion and this acted to wedge <br />the pipe in place. It was to be coupled with E-2-88 at the <br />surface where a large volume vacuum pump would be in:~talled <br />to ventilate the workings, if necessary. <br />u <br />• <br />2.04-6(j) (Revised 09/01/89) <br />
