| 3964547 | Recovery of heavy hydrocarbons from underground formations A method of producing highly viscous oil from an underground formation penetrated by a well. Steam is injected through a first channel into the lower part of the formation. At the same time, previously recovered oil from the formation is injected through ... | 06/22/1976 |
| 3954140 | Recovery of hydrocarbons by in situ thermal extraction Hydrocarbons are recovered from a subterranean formation by providing a plurality of generally horizontal boreholes in the formation. The boreholes are vertically spaced across the thickness of the formation and extend from the top to the bottom thereof. ... | 05/04/1976 |
| 3952800 | Sonic technique for augmenting the flow of oil from oil bearing formations High level sonic energy is introduced at the head of an oil well casing and transmitted through the gaseous column formed in the casing down to oil bearing strata from which oil is being extracted. The sonic energy is transmitted into this strata either t... | 04/27/1976 |
| 3951457 | Hydraulic mining technique for recovering bitumen from tar sand deposit Viscous petroleum including bitumen may be recovered for subterranean petroleum containing unconsolidated said formations such as tar sand deposits by hydraulic mining. Hot water or steam is introduced into the subterranean deposit with sufficient velocit... | 04/20/1976 |
| 3948323 | Thermal injection process for recovery of heavy viscous petroleum A new and improved process for the recovery of heavy viscous petroleum from a subterranean formation is disclosed. A heated fluid comprising steam and a heated non-condensable gas is injected into the formation through a penetrating well at an initial pre... | 04/06/1976 |
| 3948755 | Process for recovering and upgrading hydrocarbons from oil shale and tar sands A process for recovering and upgrading hydrocarbons from oil shale and tar sands by contacting the oil shale or tar sands with a dense-water-containing fluid at a temperature in the range of from about 600°F. to about 900°F. in the absence of externally... | 04/06/1976 |
| 3945436 | Method and apparatus for cleansing well liner and adjacent formations First, a cleansing fluid is injected under high pressure into a well liner and out through the apertures in the liner so as to travel through a particular slice of the underground formation adjacent the lining in order to dissolve chemical deposits and di... | 03/23/1976 |
