评估人工举升市场的未来

公司正在对传统系统采取创新方法。

早在 2014 年市场崩溃之前,石油和天然气井就需要人工举升,而且之后仍然需要人工举升。然而,与该行业的其他部门一样,人工举升市场也受到了打击。Westwood Energy今年发布的一份报告称,全球人工举升支出从2014年的近160亿美元下降到2016年的约90亿美元,降幅达43%。

然而,与其他市场类似,人工举升市场已经反弹并有望增长。

Westwood 报告称,从 2016 年低点至今年增长了 10 亿美元,并预计到 2020 年人工举升需求市场将增长 6%。

麦肯锡能源洞察去年发布的一份报告称,当时人工举升市场面临的挑战是其产品的商品化。

Dimitar Kostadinov 和 Brandon Stackhouse 在 2017 年 8 月的麦肯锡报告中写道:“最近的技术进步已经在市场上为最受欢迎的移位方法创造了差异化。” “这鼓励运营商主要根据价格来选择设备和服务,促使服务公司专注于开发低成本产品,并对市场造成持续的定价压力。”

石油和天然气公司一直热衷于应对这样的挑战。最近在德克萨斯州伍德兰举行的石油工程师学会人工举升会议和展览会上,几家公司通过技术论文或产品展览提供了人工举升系统和操作方面的进步示例。

其中包括西方石油公司对旨在优化水平井人工举升性能的尾管系统的评估(SPE-190938 论文)。该报告由 Chris Humpreys 等人撰写,重点关注一个试验项目,该项目评估了两个尾管系统的性能,该系统可应用于抽油杆泵和 ESP,以降低井底流动压力,而无需将泵降落到启动点并减少泵的段击行为的频率和幅度。

与此同时,Ambyint 和 Oasis Petroleum 等公司赞扬了在人工举升作业中采用数字化的优点。Novomet 和 GE 公司贝克休斯分享了他们公司在永磁电机方面所做的工作。

此外,Raptor Lift Solutions 还配备了带有内置变速驱动器和远程监控功能的液压升降系统。据该公司称,该系统允许操作员使用一台动力装置以两种不同的生产率独立泵送两口井。可以对一口井进行维护,而另一口井继续抽水。

AppSmiths Technology 推出了其 WellTracer 气举井诊断和监视工具,该工具有助于定位气体注入的主要点。该系统的工作原理是通过将少量 CO 2引入注入管线来创建油井性能快照,然后测量井口的 CO 2浓度。

尽管定向钻井和压力泵等服务市场比人工举升对市场条件更敏感,但行业反弹期间钻井的激增正在为举升服务创造未来的基础市场。如果公司继续寻找改进工具的方法,并且油价让人们对持续生产充满信心,那么人工举升行业应该会保持强劲。

Evaluating The Future Of The Artificial Lift Market

Companies are taking innovative approaches to traditional systems.

Oil and gas wells needed artificial lift long before the market crashed in 2014 and still needed them afterward. Like other sectors of the industry though, the artificial lift market took a hit. A report issued this year by Westwood Energy stated that worldwide expenditures for artificial lift fell from nearly $16 billion in 2014 to about $9 billion in 2016—a 43% drop.

However, similar to others, the artificial lift market has rebounded and is expected to grow.

Westwood reports $1 billion in growth from the low of 2016 to this year and predicts 6% market growth through 2020 for artificial lift demand.

A report issued last year by McKinsey Energy Insights claimed at the time the challenge for the artificial lift market was the commoditization of its products.

“No recent technological advances have created differentiation within the market for the most popular lift methods,” wrote Dimitar Kostadinov and Brandon Stackhouse in an August 2017 McKinsey report. “This has encouraged operators to select equipment and services based primarily on price, prompting service companies to focus on developing low-cost offerings and placing sustained pricing pressure on the market.”

Oil and gas companies have been keen to such a challenge. At the recent Society of Petroleum Engineers Artificial Lift Conference and Exhibition in The Woodlands, Texas, several companies, either through technical papers or product exhibitions, provided examples of advances in artificial lift systems and operations.

Among those was an evaluation by Occidental Petroleum on a tailpipe system designed to optimize artificial lift performance in horizontal wells (SPE-190938 paper). The report, written by Chris Humpreys, et al., focused on a trial project that evaluated the performance of two tailpipe systems that could be applied to sucker rod pumps and ESPs to reduce the flowing bottomhole pressure without having to land pumps past the kickoff point and reduce the frequency and magnitude of slugging behavior at the pump.

Meanwhile, companies like Ambyint and Oasis Petroleum extolled the virtues of adopting digitalization in artificial lift operations. Novomet and Baker Hughes, a GE company, shared the work their companies have been conducting with permanent magnet motors.

Additionally, Raptor Lift Solutions featured a hydraulic lift system with built-in variable speed drives and remote monitoring capabilities. According to the company, the system allows the operator to pump two wells independently at two different production rates with one power unit. Maintenance can be performed on one well while the other continues to pump.

AppSmiths Technology featured its WellTracer gaslifted well diagnostic and surveillance tool, which helps locate the primary point of gas injection. The system works by creating a snapshot of the well performance by introducing small amounts of CO2 into the injection line, then measured that CO2 concentration at the wellhead.

Although service markets like directional drilling and pressure pumping are more sensitive to market conditions than artificial lift, the proliferation of wells drilled during the industry rebound is creating a future base market for lift services. If companies continue to look for ways to evolve their tools and oil prices allow confidence in continued production, the artificial lift industry should remain robust.
