  • System for pumping fluids from horizontal wells
    Patent number: 5154588
    Abstract: Apparatus and method for pumping fluids from horizontal wells with a dip tube used without requiring a packer in the well. Gas is separated from the liquid phase ahead of the pump to avoid slug flow of gas into the pump. This increases the amount of oil that can be pumped from the well by avoiding shutdowns resulting from gas-locking of the pump.

  • Redox gel process for more uniform fluid flow in formations
    Patent number: 5035287
    Abstract: A metal-containing oxidizing solution is injected through wellbores which reacts in a subterranean reservoir which has naturally-ocurring reduction capacity to form a slightly soluble compound of metal having a valence of +3. Thereafter, the metal crosslinks a water-soluble polymer which is injected into the metal-containing pore volume resulting in a decreased flow in the treated portion of the reservoir.
