数字完井技术已完成了 36,000 多个阶段，没有发生任何一次钢丝绳或压力控制事故。这种无事故的安全性和可靠性记录鼓励石油和天然气运营商采用数字基础设施来改善水力压裂和电缆作业。智能井口系统公司 (Intelligent Wellhead Systems Inc.) 凭借其 inVision 技术平台实现了这一目标。

数字基础设施技术集成了软件、传感器和工程安全控制装置，可自动执行压裂阀操作和远程监督电缆操作的标准操作程序合规性。压裂阀启动时间缩短了 55%，电缆阀动作时间缩短了 59%。某些焊盘的交换时间已减少一半。

该技术具有强大的数据采集和控制系统 iHub，它是井场的数字完井技术大脑，用于集成水力压裂、电缆和压力控制作业数据，以创建定制的工作流程、阈值警报和其他分析应用。最新的平台创新是在边缘或云端实施运营商驱动的分析。运营商和服务公司可以通过访问实时压裂、电缆、压力控制和其他第三方数据来实施其完井性能增强算法。iHub 实时双向同步功能消除了云和现场实施之间的差距，并且 API 可确保与其他应用程序的连接和集成。

除了这些创新之外，inVision 软件技术还包括一个远程操作仪表板，可以可视化关键完成数据，帮助用户降低风险、降低成本并延长正常运行时间。实时、可配置的数字显示器是所有现场操作的虚拟窗口，可通过井场平板电脑和远程桌面计算机进行访问。可视化阀门放置和油井活动状态有助于减少人为错误并改进决策。

该软件利用各种 inVision 传感器和工程控制装置来提高完成效率：

• 阀门位置传感器提供数字阀门位置验证，消除手动目视检查。
• 阀门手柄位置传感器通过测量控制阀手柄的位置，为用户提供井口阀门对准的直观表示。
• 每口井背面的压力传感器会检测压裂压力何时超过压裂阈值压力，以防止用户解锁错误的阀门。
• 钢丝绳线轴检测井中钢丝绳的存在，并防止用户解锁可能切断钢丝绳的阀门。
• 液压阀门锁定装置可防止意外关井，并包括可视阀门位置指示器以及数字和手动紧急旁路。

如果井场用户请求访问井并且 inVision 软件检测到井中的电缆或有效压裂压力，则该请求将被禁用。如果系统检测到其安全并且请求获得批准，则会启动三向数字握手并通过 inVision 平板电脑进行。每个用户输入其唯一的 PIN，然后执行并记录该过程。如果任何时候检测到不安全状况，inVision 系统会锁定相关阀门并通知用户，然后在安全状况恢复后解锁。 

在两井同时压裂作业中，使用 inVision 数字握手流程和联锁控制来保证油井交换的安全和简化。由于参与同步压裂作业井交换的阀门数量至少是原来的两倍，因此采用了 inVision 标准操作程序来支持复杂的阀门排序，以减少人为错误。

对于单井压裂、拉链式压裂和同步压裂操作，inVision 数字完井时间序列数据通过标准数据模型提供，可以在自动进行工程分析和建模的 Corva Completions 套件上进行分析和可视化。inVision SIMOPS 应用程序让工程师能够利用 Corva 的数据分析和人工智能技术，从数字完井数据中开发关键的操作学习。inVision 生成的数据和即插即用报告也可以轻松导入 Peloton 的集成油井数据生命周期分析和可视化解决方案 WellView。

inVision 的最新开发成果是能够远程驱动液压阀，以减少井场人员面临潜在危险的风险。阀门的自动化远程操作有望进一步提高阶段效率。

在现场测试中，该开发项目将于 2022 年 3 月底与 Aethon Energy 首次商业应用，Aethon Energy 是海恩斯维尔的一家运营商，自 2020 年以来一直利用 inVision 技术平台。

A digital completion technology has delivered more than 36,000 stages without a single wireline or pressure control incident. This incident-free safety and reliability track record encourages oil and gas operators to adopt a digital infrastructure to improve hydraulic fracturing and wireline operations. Intelligent Wellhead Systems Inc. has achieved this with its inVision technology platform.

The digital infrastructure technology integrates software, sensors and engineered safety controls to automate standard operating procedure compliance for operating frac valves and remotely supervising wireline operations. Reduced frac valve activation time has reached 55%, and wireline valve action times have been cut by 59%. Well swap times on some pads have been reduced by half.

The technology features a robust data acquisition and control system, iHub, the digital completion technology brain at the wellsite for integrating hydraulic fracturing, wireline and pressure control job data to create customized workflows, threshold alerts and other analytical applications. The latest platform innovation is implementing operator-driven analytics on the Edge or in the Cloud. Operators and service companies can implement their completion performance-enhancing algorithms by accessing real-time frac, wireline, pressure control and other third-party data. iHub real-time bidirectional sync capabilities eliminate the gap between Cloud and field implementations, and APIs are available to ensure connectivity and integration with other applications.

Along with these innovations, inVision software technology includes a remote operations dashboard that visualizes critical completion data to help users reduce risk, lower cost and improve uptime. The real-time, configurable digital display, a virtual window into all onsite operations, is accessible on wellsite tablets and remote desktop computers. Visualizing valve placement and well activity status helps reduce human error and improves decision-making.

The software leverages a variety of inVision sensors and engineered controls that improve completion efficiency:

• Valve position sensors provide digital valve position verification to eliminate manual visual inspection.
• Valve handle position sensors give users a visual representation of the wellhead valve alignment by measuring the position of the control valve handle.
• Pressure sensors on the backside of each well detect when frac pressure exceeds frac threshold pressure to prevent users from unlocking the wrong valves.
• Wireline spools detect the wireline presence in the well and prevent users from unlocking valves that may cut wireline.
• Hydraulic valve lockouts prevent accidental well shut-ins and include a visual valve position indicator and digital and manual emergency bypasses.

If a wellsite user requests access to a well and the inVision software detects wireline in the hole or active frac pressure, the request is disabled. If the system detects it is safe, and the request is approved, a three-way Digital Handshake is initiated and conducted over inVision tablets. Each user enters their unique PIN, and the process is executed and recorded. If an unsafe condition is detected at any time, the inVision system locks out the relevant valves and notifies the user, then unlocks once safe conditions have been restored. 

On two-well simul-frac operations, the inVision Digital Handshake process and interlock controls are being used to keep well swaps safe and streamlined. With at least twice as many valves involved in simul-frac operation well swaps, inVision standard operating procedures have been adopted to support complex valve sequencing to reduce human error.

For single well fracs, zipper fracs, and simul-frac operations, inVision digital completion time-series data are delivered with a standard data model that can be analyzed and visualized on the Corva Completions suite that automates engineering analysis and modeling. The inVision SIMOPS app lets engineers develop key operational learnings from digital completion data with Corva’s data analytics and AI technologies. Data and plug-and-perf reports generated by inVision are also easily imported to WellView, Peloton’s integrated well data lifecycle analysis and visualization solution.

The ability to remotely actuate hydraulic valves to reduce wellsite personnel exposure to potential hazards is the latest inVision development. Automating remote operations of valves promises to improve stage efficiency further.

In field test, this development will see its first commercial application at the end of March 2022 with Aethon Energy, an operator in the Haynesville that has leveraged the inVision Technology Platform since 2020.
