ABSTRACT:
A method of drilling in a stratum and a method of enhancing recovery of a hydrocarbon material from an existing well. The method of drilling generally includes providing a drilling apparatus having at least one laterally oriented nozzle. Part of the drilling apparatus is moved downwardly along an existing bore without drilling until the nozzle is in position and pressurized hydraulic fluid is delivered through the nozzle to define a first generally horizontally oriented secondary bore. The nozzle is reoriented the nozzle is used to bore a second generally horizontal oriented secondary bore. The method of enhancing recovery may employ a similar process to define a first generally horizontally oriented secondary bore. The drilling apparatus is removed and pressurized hydraulic fluid is delivered into the main bore and the secondary bore to fracture the stratum to assist in extracting the hydrocarbon material from the well.
