Boss Hog® Frac Plugs Cut Project Time and Costs in Haynesville Shale

CHALLENGE:

A global oil and gas company operating in the Haynesville Shale wanted to reduce cost, time, and risk in multistage, extended-reach lateral completions. With previous completions as a benchmark, the company wanted to:

  • Provide an efficient, multistage completion solution that reduces over-flushing on pumpdowns.
  • Eliminate premature frac plug settings.
  • Effectively seal in the extreme well environment exceeding 350°F.
  • Minimize drillout time and risk.

RECOMMENDATION:

Downhole Technology proposed using the Boss Hog® composite fracplug with the HELISEAL® Fluid Propulsion System; one-piece lower slip and composite upper slip.

The HELISEAL design allows for a no-resistance free fall in the vertical section of the well and provides an inflated surface area allowing horizontal pumpdown with less fluid use and a faster run rate. The patented, one-piece lower slip is pre-segmented to prevent presets and allows the operator to maintain isolation and pressures exceeding 15,000 psi and temperatures above 350°F. The composite upper slip with noncarbide inserts circulate to the surface, along with the small cuttings when the plugs are drilled out.

RESULTS:

  • 43% more efficient pumpdown fluid.
  • 218,000 gallons of fluid saved between two wells.
  • Only 3.3 barrels of fluid per 100 feet used.
