Patent ID: 8256537

Claim:
A method of blasting lateral holes in a formation around a well bore, the well bore containing production casing, and production tubing within the production casing, the method comprising the steps of: (a) removing the production tubing from the production casing; (b) attaching a ninety-degree deflection shoe to the bottom of the production tubing, the deflection shoe having openings to receive fluid, and having rollers for guiding a hose at a ninety-degree angle from the production tubing and into the formation; (c) attaching a short double-braided stainless steel flexible hose to a first end of coiled tubing, the hose having an operating pressure of 5,000 psi and a burst pressure of 10,000 psi; (d) reinserting the production tubing into the production casing; (e) centering the coiled tubing over the production tubing; (f) forcing the short flexible hose, attached to the coiled tubing, down to the bottom of the production tubing, and into the deflection shoe, while simultaneously forcing circulating fluid down through the production casing; (g) forcing cutting fluid under pressure between 2,000 and 5,000 psi through the coiled tubing and thus through the short flexible hose, thus creating a pilot hole in the formation, and creating spent cutting fluid, while simultaneously forcing circulating fluid down through the production casing; (h) extracting the coiled tubing and the short flexible hose from the production tubing, while simultaneously forcing circulating fluid down through the production casing; (i) replacing the short flexible hose with a long double-braided stainless steel flexible hose, the long hose having an operating pressure of 5,000 psi and a burst pressure of 10,000 psi; (j) forcing the long flexible hose, attached to the coiled tubing, down to the bottom of the production tubing and into the deflection shoe, while simultaneously forcing circulating fluid down through the production casing; (k) forcing cutting fluid under pressure between 2,000 and 5,000 psi through the coiled tubing and thus through the long flexible hose, thus blasting a lateral hole in the formation, and creating spent cutting fluid, while simultaneously forcing circulating fluid down through the production casing; and (l) extracting the coiled tubing and the long flexible hose from the production tubing, while simultaneously forcing cutting fluid under low pressure through the coiled tubing and thus through the long flexible hose, and while simultaneously forcing circulating fluid down through the production casing.
