“Highly Effective” Balanced to Underbalanced Well Cleaning
“Economically Priced” 24 hour operations for longer reach horizontal wells
“Ultra Competitive Cost” 12 hour operations for thru-tubing well completions
Well Service Overview
Alberta companies Efficient Technologies Inc., and partner Petrospec Engineering Inc. provide pressure-balanced wellbore cleaning by conveying their unique E-Vac tool in a coiled tubing format. The primary objective of this technology is to create a low-pressure environment in the wellbore to pump fluids and/or solids to surface in the absence of back pressure on the well reservoir.
Efficient’s specialized “E-Vac Tool” is deployed in the well using concentric umbilical coiled tubing. The E-Vac Tool is specifically configured with both a venturi and jetting nozzle facilitating concurrent solids jetting and production of emulsion to a surface holding tank.
A common problem with horizontal well types is solids accumulation in the lateral section. This inhibits inflow resulting in lost productivity. Using conventional well cleaning procedures, lower pressure wells become overbalanced defeating the purpose of the cleanout operation. Using Efficient’s pressure balanced cleanout technique, all wellbore solids are evacuated from the well with a minimum disturbance to the formation.
