Deviated well drilling involves drilling horizontal and slant-hole wells to better intersect vertical fractures in tight formations. Natural vertical fractures are important factors in the economic production of gas from these rocks because the permeability of the natural fractures is almost always much higher than the unfractured rock. However, most of the gas resources reside in the rock pores and move out of the rock to the wellbore via fractures. The vertical lines represent natural fractures in blanket and lenticular reservoirs. DOE and industry are experimenting with these new methods of producing gas from tight reservoirs.
