| 20090283257 | RADIO AND MICROWAVE TREATMENT OF OIL WELLS - A method including exposing a substance to a first type of electromagnetic waves generated by a first device. The frequency of the first type of electromagnetic waves is in the radio frequency range and the device consumes no more than about 1,000 Watts of power. The exposure takes place for a period of time and at a frequency sufficient to detectably alter at least one physical property of the substance as it existed prior to the exposure. | 11-19-2009 |
| 20090298722 | Emulsion Breaker - This invention provides acrylate polymers having at least two different ester groups. The ester groups are selected from the following:

| 20100029514 | NAPHTHENIC ACID SOLIDS DISSOLVER COMPOSITIONS AND METHODS RELATED THERETO - Methods and compositions are provided for dissolving naphthenic acid solids from oilfield systems. The composition includes glacial acetic acid and a solvent that is soluble in the glacial acetic acid or a solvent in which the glacial acetic acid is soluble. | 02-04-2010 |
| 20100105580 | Polymers For Oilfield Applications - This invention provides polymers having side chain groups selected from at least one of the following: | 04-29-2010 |
| 20100175875 | Squeeze Process For Reactivation Of Well Treatment Fluids Containing A Water-Insoluble Adsorbent - A process for fracturing a subterraneous formation in the production of an oil well is described. The process steps include injecting an initial charge of a mixture, the mixture being formed from at least a water-insoluble adsorbent and at least one well treatment agent, into a well bore formed in the subterraneous formation so as to form a downhole matrix within the formation; injecting a solution comprised of an additional amount of the well treatment agent into the formation after the initial charge of the at least one well treatment agent has been substantially depleted; and then pressurizing the well bore for a time and under conditions sufficient to reactivate the downhole matrix in the formation, so that the treatment agent activity of the matrix is increased relative to the treatment agent activity of the matrix just prior to injecting the solution. | 07-15-2010 |
| 20110079402 | Apparatus And Method For Directionally Disposing A Flexible Member In A Pressurized Conduit - An apparatus and method for directionally disposing an elongated flexible member in a pressurized conduit. The method includes inserting a bent end portion of an elongated hollow body through an opening in fluid communication with a well valve and defined by a pressurized conduit, the bent end portion being disposed in a pre-determined direction and location within the pressurized conduit; inserting a lead portion of an elongated flexible member into a fluid passageway defined by a primary valve, the fluid passageway of the primary valve being in sealed fluid relationship with the elongated hollow body which, in turn, is in sealed fluid relationship with the pressurized conduit, so that the lead portion of the elongated flexible member is inserted through the bend end portion and into the pressurized conduit by a pre-determined distance; and thereafter retaining in place the inserted elongated flexible member, whereby the elongated flexible member is directionally disposed in the pressurized conduit. | 04-07-2011 |
| 20110284231 | Electromagnetic Wave Treatment Of Oil Wells - A method including exposing a substance to a first type of electromagnetic waves generated by a first device. The frequency of the first type of electromagnetic waves is in the radio frequency range and the device preferably consumes no more than about 1,000 Watts of power. The exposure takes place for a period of time and at a frequency sufficient to detectably alter at least one physical property of the substance as it existed prior to the exposure. The substance is selected from the group consisting of a hydrate, a water and oil emulsion, clay, scale, cement, a completion fluid, tank sediment and iron sulfide. | 11-24-2011 |
| 20120018159 | Polymer Hydration Method - Disclosed is a method of rapidly hydrating a hydratable polymer, which method involves irradiating with radio frequency electromagnetic radiation, a mixture of at least the polymer and an aqueous hydrotreating medium to form a viscosified mixture of at least aqueous hydrotreating medium and hydrated polymer. Related methods of treating a subterranean formation and continuously hydrotreating a subterranean formation are also revealed. | 01-26-2012 |
