Case Study: Enterprise Web App Development for a Global Oil & Gas Firm

Overview

A global oil and gas company was facing increasing challenges due to mounting inefficiencies in its field operations. With hundreds of remote technicians, outdated communication processes, and disconnected systems, the organization struggled to maintain efficiency and control costs. Recognizing the urgent need for change, they sought a modern, scalable solution to streamline operations and reduce overhead.

In response, they turned to Tevpro—a trusted leader in enterprise web app development—to modernize their field operations through a cloud-enabled mobile solution.

The Challenge: Outdated Systems, Slow Response, High Costs

The client’s critical infrastructure consisted of oil wells, pumps, tanks, and other essential assets. As a result, these assets required maintenance from hundreds of on-site technicians, supported by a massive 24/7 call center. This call center played a pivotal role, monitoring field sensors and manually dispatching technicians by phone whenever issues arose.

Despite these efforts, several key pain points emerged.

  • Delayed response times – Alarms could take hours—or even days—to reach the appropriate technician.
  • Legacy SCADA systems – Data remained siloed across outdated platforms, resulting in limited visibility.
  • Manual dispatching – The reliance on phone calls and laptops significantly slowed operations.
  • High operational costs – Running a call center and coordinating manual dispatch proved to be resource-intensive.

Consequently, these bottlenecks hindered productivity and increased downtime across operations. To overcome these obstacles, the oil firm partnered with Tevpro to initiate its digital transformation.

The Solution: A Real-Time, Cloud-Enabled Mobile Field Application

Tevpro’s team designed and delivered a custom enterprise mobile app built for rugged field environments and powered by real-time sensor data.

Technologies Used:

  • Frontend – Angular & Ionic Framework are used for responsive mobile experiences.
  • Backend – C# .NET for robust server-side processing.
  • Cloud – Microsoft Azure for scalable data storage, analytics, and security.

Key Features:

  • Real-time integration with multiple legacy SCADA systems.
  • Mobile access to field data, alerts, and asset history.
  • Auto-generate service tickets from sensor inputs.
  • In-app task management, system testing, and work order closure.
  • Push notifications, SMS, and email alerts for technician dispatch.
  • Escalation service to ensure critical alarms are addressed.

Together, these features streamlined field operations and enhanced the efficiency of technicians in real-time. Workers in the field can now collect, analyze, visualize, and share time-series data from any tablet or mobile device.

Results: Increased Field Efficiency, Faster Response, and Reduced Downtime

Ultimately, the mobile app transformed the way field technicians operate. Notable benefits include:

  • Faster response times – Real-time alerts allow for immediate technician dispatch.
  • Reduced costs – Automation minimized dependence on the call center.
  • Anywhere access – Technicians can manage repairs, upload photos, and track hours from any device.
  • Better decisions – Real-time cloud analytics help identify trends and prevent future issues.
  • Automated workflows – Task escalations flag issues and automatically assign them to a designated field technician.

In addition, Tevpro’s forward-thinking approach to enterprise app development enabled the client to streamline operations and minimize unnecessary downtime.
