Total Drilling Footage Table <br />UI1C <br />EDERGY <br />3.2 Drilling Program (Phase 2) cont. <br />Assuming 2,500 feet per hole, a total footage of 25,000 feet is envisioned and will be a <br />mix of rotary and core drilling methods. Drilling will be a combination of air - rotary (water <br />injection), mud - rotary and continuous core as ground conditions warrant. After the <br />surface casing is set, the hole will likely be rotary drilled to the desired core point. <br />Approximately 200 feet of the roof and 50 feet of the floor of each thick target seam are <br />planned for coring. Assuming two target coal seams per hole approximately 550 feet or <br />22% of the section is planned for coring. The remaining 1,950 feet is planned for rotary <br />drilling. These estimates are subject to change after more in -depth analysis. Currently <br />the following footage is estimated for the Little Snake River Area: <br />Cased open hole: 200' <br />Rotary open hole: 19,300' <br />Core drilling: 5,500' <br />Total Footage: 25,000' <br />Linc Energy drilling personnel will review the available types of drilling equipment needed <br />and available to drill these planned sites. In addition the rig must be designed to easily <br />handle a 2,500 hole and be able to handle casing for possible groundwater monitoring <br />well conversion. <br />Due to the softness of the Tertiary coal- bearing strata, drilling fluid that would create a <br />mud cake along the annulus of the hole may be needed to assure an open hole suitable <br />for geophysical logging. However, air /foam drilling mediums will be considered due to <br />lower cost and speed of completion. <br />8 <br />
