Wokha district is situated in the mid-western part of the state. The landform of the district is marked by a series of sub-parallel hill ranges running in a north-east to south-west direction rising one after another towards east with intervening valleys. They are comprised of tertiary sequence belong to an igneous and sedimentary types. The western part of the State of Nagaland which includes Wokha district has been surveyed by Assam Oil Company, subsequently geological and geophysical surveys have been carried out by Oil and Natural Gas Corporation (ONGC). As a result of these surveys, it has been revealed that a large thickness of sedimentary rock sequence of tertiary age is exposed in this area. The boundary between Naga hills and upper Assam plain is marked by thrust fault – Naga thrust. The rocks underlying the Naga thrust are in general undisturbed. On the basis of these surveys along with laboratory analysis of the rock samples, it was assured that this part of Nagaland holds good hydrocarbon prospects, particularly within the lower tertiary sequence. Under this condition, the ONGC drilled a well in 1973 in Changpang area of this district which proved the existence of commercially exploitable hydrocarbon. On the foot hills of the district, coal deposit have been located in various places. Besides coal, sandstone suitable for, road metals also occurs in abundance in the district.
