Maximizing Total Available Pumping Time with Innovative Wireline Completion Technologies

Horizontal well completion trends have migrated toward multiwell pads with zipper fracs that

  • Optimize spacing and stacking
  • Increase lateral length with some approaching 20,000 ft
  • Have a greater number of frac stages, as high as 100 stages per well
  • Reduce stage lengths from 250 to 300 ft down to 150 to 200 ft
  • Space up to 30 perforation clusters as close as 10 ft apart.

This trend requires an extremely safe and efficient execution approach specifically designed for these multiwell pads. The optimization goal is to lower completion time, reduce risk, decrease operating cost and maximize total available pumping time.

Reliable Connectivity in Oilfields Gives GR Access to Real-time Data

GR Energy Services had been expanding the reach of its oilfield measurement equipment aboard wireline trucks throughout the United States, but one missing component was hindering operational efficiency: network connectivity in out-of-the-way locations and the ability to securely access real-time data remotely.

In partnership with GR, INS implemented Cradlepoint's cloud-managed, all-in-one routers in each vehicle, which gave GR reliable connectivity, comprehensive security, and robust cloud management tools to increase efficiencies by connecting its vehicles to the Internet and to the company network. Cradlepoint's purpose-built in-vehicle solution provides Unified Threat Management (UTM), multizone firewall, web content filtering, and Intrusion Prevention and Detection Systems (IPS/IDS).

By using Cradlepoint's high-performance 4G LTE routers with dual-modem functionality, GR has automatic and instant cellular-to-cellular failover whenever one carrier's coverage drops off. The system also leverages load balancing, using multiple carriers to ensure the flexibility of keeping GR trucks connected all the time, even in the middle nowhere.

With always-on connectivity, GR avoids making unnecessary trips to the wellsite, and operators are ensured reliable online access to real-time data.

With a built-in firewall, CP Secure Web Filter, CP Secure Threat Management for IPS/IDS, and a constant VPN tunnel back to the data center, GR has the information security it needs to block unwanted website usage and protect employees and the network from malicious sites.

Permian Basin Saltwater Disposal Performance Package

The GR Energy Services Flex Flow* HPS SWD system integrates a surface horizontal pumping system with variable speed drives, surface controls and automated reporting capabilities to lower the total cost of operations of saltwater disposal. With trailer-mounted or permanent installations, the Flex Flow HPS SWD system offers significant cost and performance advantages over conventional triplex positive displacement pumps. The system has been optimized for Permian Basin applications with field-proven directly-coupled, multistage centrifugal pumps designed for high pressure, low- to- medium-flow saltwater transfer and injection. Surface facilities engineers using these systems have documented lower maintenance and repair costs, longer run-life and greater operating flexibility and efficiency.
