Abstract
A method for oil, gas and mineral recovery by panel opening drilling including providing spaced injection and recovery drill holes (10, 12) which respectively straddle a deposit bearing underground region (20), each drill hole including a panel shaped opening (18, 19) substantially facing the deposit bearing region (20) and injecting the injection hole (10) with a fluid under sufficient pressure to uniformly sweep the deposits in the underground region to the recovery hole (12) for recovery of the deposits therefrom. An apparatus (50) for creating such panel shaped is also provided.

Method for oil, gas and mineral recovery by panel opening drilling comprising:
- (a) providing spaced apart injection and recovery drill holes extending along respective longitudinal axes into an underground area having a deposit bearing region,
- (b) drilling a first panel shaped opening outwardly of the injection hole by cutting the underground area adjacent the injection hole, said first panel shaped opening substantially facing the deposit bearing region, and
- (c) injecting said injection hole with a fluid under sufficient pressure to uniformly sweep the deposits in the underground area to said recovery hole for recovery of the deposits therefrom.
Method for oil, gas and mineral recovery by panel opening drilling comprising:
- (a) providing at least first, second, and third spaced apart drill holes extending along respective longitudinal axes into an underground area having a deposit bearing region,
- (b) drilling a panel shaped opening outwardly of each respective drill hole by cutting the underground area adjacent each drill hole, said panel shaped openings being spaced from one another and substantially parallel to one another with two of said openings being aligned substantially in a common plane and the third opening being spaced from and substantially parallel to said common plane, said third opening having portions thereof overlapping respective portions of the other two openings, at least one of said holes being an injection hole and at least another of said holes being a recovery hole, and
- (c) injecting a fluid into said at least one injection hole under sufficient pressure to uniformly sweep the deposits in the underground area to said at least one recovery hole for recovery of the deposits therefrom.
