A customer performing plug-and-perf completions in Washington County, Pennsylvania, wanted to decrease plug drill out times and eliminate extensive debris removal by using disintegrating frac plugs in a deep well with a low bottomhole temperature (BHT) of around 130ºF.

Low BHT is known to decrease the effectiveness of disintegration, which sometimes results in failed treatment diversion and/or the need for extra plug runs. Additionally, partially disintegrating plugs containing metal slips and carbide buttons leave debris behind in the wellbore, increasing the risk of casing damage.

For this job, Baker Hughes, a GE company (BHGE), suggested running SPECTRE™ low temperature (LT) disintegrating frac plugs. SPECTRE plugs are the industry’s first fully disintegrating plug, enabling customers to skip the costly and time-consuming process of post-frac plug millout. The plug reliably withstands the rigors of fracturing, and the entire plug—including the body, specially engineered slip system, and packing element—fully disintegrates downhole in the presence of wellbore fluid, eliminating unexpected milling costs and/or extra cleanup costs associated with non-disintegrating plug components.

Challenges

  • Frac plug disintegration at low bottomhole temperature (BHT)
  • Increased drill out times with composites resulting in delayed production
  • Reaching total depth (TD) in a 17,300 ft well

Results

  • Eliminated significant clean out time verses traditional composite plugs
  • Allowed for continued production from the lower zones
