| 20090126999 | Compositions and Methods for Water Control and Strengthening Unconsolidated Formations - The present invention relates, in general, to subterranean fluids, and more particularly, to subterranean drilling fluids that may be useful for reducing the production of water from a portion of a subterranean formation and/or stabilizing an unconsolidated portion of a subterranean formation while drilling. In some embodiments, the present invention provides methods of reducing the flow of water from a portion of a subterranean formation that comprise contacting the portion of the subterranean formation with an organoaluminum compound, the organoaluminum compound being capable of forming a reaction product in the presence of water. The present invention also includes methods of drilling a well bore in a subterranean formation, methods of enhancing the stability of an unconsolidated portion of a subterranean formation, methods of stabilizing an unconsolidated portion of a subterranean formation, and drilling fluids. | 05-21-2009 |
| 20130284519 | Gravity Based Fluid Trap - A method to be used when performing drilling in a well bore and a device for performing the method are disclosed. The method includes positioning in the well bore a drill string comprising at least two pipe conduits, an upper end, and a lower end comprising a drilling tool, thereby forming an outer annulus between the well bore wall and the drill string. A well bore section comprising at least one u-shaped section is drilled. A first fluid with a first density is fed into the outer annulus above the u-shaped section, and a second fluid with a second density is provided within the drill string and around the tool, where the first density is larger than the second density. | 10-31-2013 |

| 20150354323 | NON-ALKYL PYRIDINE SOUR CORROSION INHIBITORS AND METHODS FOR MAKING AND USING SAME - Corrosion inhibiting compositions include at least one dialkyl sulfate quaternary salt of 1,2-disubstituted imidazolines and may include dialkyl sulfate quaternary salts of 1,2-disubstituted imidazoline amides, amides of polyamines, and/or polyamines, and an intensifier system in the presence or absence of a solvent system and methods for making and using same. | 12-10-2015 |
| 20160083640 | Hexadecene Synthetic Drilling Fluid with Improved Environmental Properties - The disclosure relates to drilling fluid compositions, and their method of use, comprising a C16 unbranched internal olefin, including blends of the C16 unbranched internal olefin and a C16 linear alpha olefin. The exemplary drilling fluids are characterized by properties, e.g., pour points and kinematic viscosities, that enable them to be particularly useful in deep water drilling operations and have reduced environmental impact, e.g., increased biodegradation and reduced sediment toxicity. | 03-24-2016 |

| 20160186032 | DRILLING FLUID COMPOSITION AND METHOD USEFUL FOR REDUCING ACCRETION OF BITUMIN ON DRILL COMPONENTS - Disclosed is an anti-accretion additive for aqueous drilling fluids and methods to use thereof. The anti-accretion additive reduces bitumen and/or heavy oil materials from sticking to metal surfaces such as drill bits, drillstring, casing, and the like. Specifically, the anti-accretion additive comprises from 5 to 50 parts by weight of a propoxylated alcohol and from 95 to 50 parts by weight of a propoxylated and ethoxylated alcohol. | 06-30-2016 |
