Optimizing IT Infrastructure for an Independent Refinery in the Eagle Ford Basin

Comprehensive IT Managed Services to Enhance Core Business Operations and Resource Efficiency


The client is an independent refinery located in the Eagle Ford basin, specializing in processing crude oil and condensate. Their production capabilities include liquefied petroleum gas (LPG), regular gasoline, ultra-low sulfur diesel, and atmospheric tower bottoms. Known for delivering high-quality petroleum products efficiently and reliably, the refinery plays a vital role in the energy sector.

The client focuses on refining crude oil and condensate from the Eagle Ford basin and producing essential fuels, including LPG, gasoline, ultra-low sulfur diesel, and atmospheric tower bottoms.


The client faced the challenge of managing their IT infrastructure while focusing on their core business operations. Their existing IT setup was not adequately supporting their needs, leading to inefficiencies and potential disruptions. To address this, they needed a reliable IT Managed Services Provider to take over their IT operations, allowing internal resources to concentrate on refining activities.

  • Network Infrastructure Overhaul: Replaced firewalls and recreated the network topology across four sites, incorporating WiFi, VLANs/IP scopes, VPN, security hardening, and Internet upgrades with failover.
  • Phone System Upgrade: Transitioned from a legacy PBX system to a modern UCaaS solution.
  • Hypervisor Migration: Migrated from QEMU to Hyper-V to improve virtualization performance.
  • Local Storage Upgrades: Enhanced local storage and optimized backup processes.
  • Active Directory Migration: Migrated from Linux to MS Active Directory for better identity management.
  • Enhanced Security: Implemented Endpoint Detection and Response (EDR), Antivirus (AV), and Security Operations Center (SOC) services.
  • Cloud Migration: Moved local shares and HomeDrive data to Microsoft SharePoint for improved accessibility and collaboration.
