Abstract
A bottom hole assembly (BHA) includes components to perform a fracturing process for small hole wells created by underbalanced coiled tubing drilling. The BHA can be used to drill a wellbore and to stimulate an underbalanced coiled tubing drilled well. The BHA, coupled to a coiled tubing, can include a drilling bit, a hydrajetting tool up-string from the drilling bit, and a diverter between the drilling bit and the hydrajetting tool. After the BHA drills a wellbore, the BHA can be moved so that the hydrajetting tool is positioned to perform perforation without removing the BHA from the wellbore. The hydrajetting tool can perforate the formation using a regular perforation fluid first, then using a cooling agent to cool the wellbore area covering the coplanar perforation cluster, and last propagate hydraulic fracture by injecting the main pump schedule through the tubing and the annulus at the same time.
