Emerging trend of allocation wells and cross unit drilling in the Appalachian Basin
Allocation wells and cross unit drilling have the potential to create more economic wells using longer laterals, while overcoming unit size limitations commonly found in oil and gas leases. An allocation well is a lateral wellbore that crosses multiple lease boundaries of tracts that have not been pooled or unitized. Similarly, cross unit drilling involves laterals that traverse multiple units.
The use of allocation wells and cross unit drilling in Texas and Oklahoma has evolved out of legislation, administrative rulings and case law. Allocation drilling and cross unit drilling are not yet widely used in the Appalachian Basin, but as drilling technology evolves it is likely that operators will look to the feasibility of employing that technology across the basin.
The biggest risk with allocation wells in the Appalachian Basin is the lack of specific authority under most standard Appalachian Basin leases granting the operator the authority to drill allocation wells. Consequently, possible claims might be asserted challenging an operator’s transportation of non-native gas across leased lands or the commingling of native and non-native gas produced from separate units or leases. Another issue associated with the potential use of allocation wells is determining the appropriate method of allocating production royalties between the different lessors. …
