    Table 5.1 provides an outline of the procedures and operations required to locate, drill, and complete a typical unconventional well in Pennsylvania, while Figure 5.1 indicates the average time required for each phase.

    Table 5.1: Outline of procedures and operations required to locate, drill and complete a typical unconventional well in Pennsylvania.
    Exploration Phase (the geology) Leasing Phase (the people and contracts) Drilling Phase (the engineering and inspection) Production Phase (the engineering and infrastructure)
    1. Basin scale assessment (data analysis, available well information) 1. Identifying "sweet spots" 1. File for and receive Permit from state regulators (plan for drilling) 1. Production and takeaway of hydrocarbons(gathering lines)
    2. Seismic data acquisition and interpretation 2. Approaching landowners/owners of mineral rights 2. Site preparation and plan for drilling, including safety plan 2. Site restoration
    3. Securing a block of leases 3. Rig setup and drilling operations(water access)
    4. Cementing and wellbore integrity considerations (geophysical logs)
    5. Hydraulic fracturing operations
    6. Well completion and testing
