Abstract

The recent downturn in energy prices has shone a spotlight on the issue of cleaning up inactive oil and gas wells. In Alberta, mounting insolvencies have caused the number of “orphaned” wells – i.e., without a financially accountable owner – to balloon from fewer than 100 to 3,200 in the past five years. With low energy prices, that list of wells risks growing longer. Of the roughly 450,000 wells registered in the province, approximately 155,000 are no longer producing but not yet fully remediated. These wells impose potential risks and costs not borne by those who benefited during the productive phase. These include the opportunity cost of taking up land that can’t be used for other purposes, risks to households from released gas and explosions, risks to the local environment from water and soil contamination, and broader risks due to leaking greenhouse gases. Moreover, the cost to clean up wells from no-longer-viable owners has the potential to spill over to surviving firms in the industry and, ultimately, citizens. In a stress test, we estimate the potential social cost of well liabilities to be as high as $8 billion. Alberta, along with other energy producing provinces in Canada, has a system in place to manage the risk of end-of-life well liability. However, a system that worked in the past is now strained under the weight of low prices. In addition, a recent court decision placing financial creditors in higher priority than environmental liabilities has further degraded the efficacy of current policies. This speaks to the need for reform. To its credit, the Alberta government is in the midst of consultations on reforming the province’s well liability policies. In this Commentary, we propose a two-part solution of partial bonding and mandated insurance for existing and new wells. First, we recommend the province introduce an upfront bonding requirement. However, this bonding requirement should be less than the full expected liability cost. This recognizes that society should accept some risk in exchange for greater economic activity, as well as aligning with the time profile of a well’s net asset value. Second, once a well enters the inactive phase, the province should require companies to hold insurance to cover the cost of cleaning up the well. In comparison to a strict time limit on inactive wells, an insurance requirement would allow firms to weigh the increased cost of holding unproductive wells against the potential value of returning them to production. We hope our recommendations are considered by the current Alberta review of end-of-life well policies, due to report by the end of 2017.
结局好,一切都好:解决油气井的寿命终止责任
最近能源价格的下跌使清理闲置油气井的问题成为人们关注的焦点。在艾伯塔省,越来越多的破产企业导致“孤儿”井(即没有财务上负责任的所有者)的数量在过去五年中从不到100口激增至3200口。由于能源价格低迷,这类油井的数量可能会越来越多。在该省登记的约45万口井中,约有15.5万口井不再生产,但尚未完全修复。这些井带来了潜在的风险和成本,而这些风险和成本在生产阶段并不是由受益方承担的。这些风险包括占用不能用于其他目的的土地的机会成本,释放的天然气和爆炸对家庭的风险,水和土壤污染对当地环境的风险,以及温室气体泄漏带来的更广泛风险。此外,清理那些不再有生存能力的业主的油井的成本有可能溢出到行业中幸存的公司,最终波及到公民。在压力测试中,我们估计油井负债的潜在社会成本高达80亿美元。与加拿大其他能源生产省份一样,阿尔伯塔省也有一个管理油井报废责任风险的系统。然而,这个过去行之有效的系统现在在低价格的重压下变得紧张起来。此外,最近法院的一项裁决将金融债权人置于环境责任之上,这进一步降低了现行政策的效力。这说明了改革的必要性。值得赞扬的是,艾伯塔省政府正在就改革该省油井责任政策进行磋商。在这篇评论中,我们提出了一个由两部分组成的解决方案,即对现有井和新井进行部分担保和强制保险。首先,我们建议该省引入预先担保要求。然而,这种担保要求应低于全部预期责任成本。这一观点认为,社会应该接受一些风险,以换取更大的经济活动,并与油井净资产价值的时间曲线保持一致。其次,一旦油井进入闲置阶段,该省应要求公司持有保险,以支付清理油井的费用。与严格的闲置井时间限制相比,保险要求将允许公司权衡持有闲置井的增加成本与将其恢复生产的潜在价值。我们希望我们的建议能被当前的艾伯塔省报废井政策审查所考虑,该审查将于2017年底报告。
