摘要

Oil and gas developers are required to post an environmental bond to cover the cost of land reclamation. As of 2009, there were more than 68,000 active oil and gas wells in the state of Wyoming operated by approximately 900 separate firms. This level of activity suggests that reclamation issues will be important in the future as these wells are either properly reclaimed or abandoned.;The objective of this study is to establish a dynamic model for oil and gas development that includes a reclamation bond and the cost of reclamation. I provide analytical solutions to the variables of interest and show phase diagrams indicating a stable equilibrium on a saddle path. I also provide numerical simulations of oil and gas development, and solve for an optimal reclamation bonding rate per well using the General Algebraic Modeling System (GAMS) software. The results indicate that current bonding rates are too low and should be increased and tied to production.
