摘要

作业合同在钻井行业越来越普遍,尤其是近年来。这种激励合同结构是作业者和承包商之间的合作伙伴关系,在提高油井性能和作业执行力的同时,将钻机承包商作为油井运营绩效的额外利益相关者。存在许多类型的绩效合同,它们都有一个共同的目标:如果达到了目标,所有相关方都将受益。一种越来越常见的绩效合同类型是分层结构的KPI(关键绩效指标)格式。在这种格式中,以kpi的形式确定度量标准,并在分层系统中设置目标范围。之前的研究和数据收集需要多个部门的努力,以确定可实现的和可扩展的指标。在目标达成一致后,确定现场人员、经验丰富的钻机领导和全面的技术支持,为成功奠定基础。建立有效的沟通结构对于持续改进至关重要。这是通过现场和办公室人员定期召开的钻机承包商和运营商的性能改进会议来实现的。在这里,可以共享成功和失败的相关性能数据,并收集和实施未来井所需的改进措施。在这种情况下,采用了四层激励结构,并使用kpi来测量周期时间/天、连接次数、起下钻速度和滑动时间。随着时间的推移,绩效合同结构有利于运营商和承包商之间的关系,使其在目标和责任上更加一致。一个持续的沟通线路允许频繁的头脑风暴和渴望尝试新方法,导致一个独特的机会来展示价值,几乎立即产生结果。某些承包商的技术可供作业者使用,因为这些技术有利于油井计划,为最初没有考虑到的技术创造了更多的开放性。绩效合同允许不断提出这样的问题:“这是否有助于我们实现总体目标?”对持续改进的持续关注导致性能基准的不断审查和新数据的微调。没有真正的“放之四海而皆准”的解决方案——尽管每个人都尽了最大的努力,但并不是所有的合同都能在油井释放时成功。作业者和承包商都必须持续做好应对快速失效的准备,识别改进机会,做出改变,并共同努力。然而,在不断发展的钻井行业和能源格局中,所有的合同最终都发挥了创新精神的作用。在整个部署过程中,与没有激励的钻机相比,这种合同结构带来了更高、更稳定的性能。总体而言,与去年的基准相比,该钻机的平均每天钻井英尺增加了8.2%。42%的井落在平均英尺/天的半标准差范围内,这是一个高度一致的区域。此外,该钻机在不同的目标地层中钻出了两口破纪录的井。我们将探讨性能合同结构如何以及为什么能够产生高性能井的一致交付。

Drilling Performance Contract: An Evolution in the Partnership Between Operator and Rig Contractor
Performance contracts are increasingly common in the drilling industry, especially in recent years. This incentivized contract structure, established as a partnership between operator and contractor, improves both well performance and operational execution while incorporating the rig contractor as an additional stakeholder in the operational performance of the well. Many performance contract styles exist, with one common goal: if targets are met, all parties involved benefit. An increasingly common performance contract type is a tier-structure KPI (Key Performance Indicator) format. In this format, metrics in the form of KPIs are determined, and goal ranges are set in a tiered system. Prior research and data collection, requiring effort from multiple departments, is needed to determine achievable and stretch metrics. After the goals are agreed upon, field personnel, experienced rig leadership, and comprehensive technology support are determined, forming a foundation for success. Establishing an effective communication structure is crucial for continuous improvement. This is achieved by regular performance improvement meetings, occurring among field and office personnel, for both the rig contractor and operator. Here, relevant performance data is shared regarding both successes and failures, with improvements needed for future wells are captured and implemented. In this instance, a four-tiered incentivized structure with KPIs measuring cycle time ft/day, connection times, tripping speeds and skid times were used. Over time, the performance contract structure benefits the operator/contractor relationship, with greater alignment on goals and responsibilities. A constant line of communication allows for frequent brainstorming and an eagerness to trial new methods, leading to a unique opportunity to demonstrate value with near-immediate results. Certain contractor technologies are at the operator's disposal as they benefit the well program, creating more openness to technologies not initially considered. Performance contracts allow for the continuous questioning of, "does this help us achieve our overall goal?" The constant focus on continuous improvement leads to performance benchmarks continually reviewed and fine-tuned with new data. There is no true "one size fits all" solution - despite everyone's best efforts, performance contracts don't all succeed at well release. Both the operator and contractor must continually be prepared to fail fast, identify improvement opportunities, make changes, and work together. However, all performance contracts ultimately play a part in innovative spirit while implementing fundamental changes in an evolving drilling industry and energy landscape. Over the course of deployment, this contract structure led to increased and more consistent performance compared to the unincentivized rigs. Overall, the rig experienced an 8.2% increase in average feet drilled per day compared to the operator's prior year benchmark. 42% of wells fell within the half-standard deviation boundaries of the mean ft/day, a highly consistent zone. Additionally, the rig drilled two record-breaking wells in different target formations. We will explore how and why the performance contract structure can yield consistent delivery of high-performance wells.
