Inactive oil and gas wells present an environmental hazard if not properly plugged. Upon drilling a well, operators are required to post a bond, which ensures that the operator has an incentive to plug and abandon (P&A) at the end of the well's life, and that, if the state is left with the liability of managing "orphaned" wells, it can cover the cost of P&A. Using data from 13 state agencies on their orphaned well plugging expenditures, we provide new estimates of P&A costs in the United States and compare them to bond amounts. Current state bonding requirements are insufficient to cover the average P&A cost of orphan wells in 11 of these 13 states. These should be reviewed and revised where necessary. We also examine the factors influencing P&A costs using detailed data on orphaned wells in Kansas. Given the variability of P&A costs, bonds would be more effective if they varied by factors that are meaningful in explaining P&A costs, such as well depth, location, and proximity to groundwater. State regulators can use the statistical approach developed in this paper to improve bonding requirements and to better predict the P&A costs of their orphaned wells.

This article sets forth a critical integrative review of the study of gender, sexuality, and religion. Treating religion as a cause, an effect, and an intermediary factor in relation to gender and sexuality, it draws on and synthesizes multiple theoretical approaches including gender and queer lenses on religion, cultural analysis, and intersectionality. The article is structured around ten big-picture questions about gender, sexuality, and religion and argues that gender and sexuality are a key symbolic boundary and cultural divide in religious and political life in the United States and around the world. It concludes with an agenda for future research.
