Abstract: The present invention relates to systems and methods for well planning and management in a field to maximize the production of hydrocarbons. Specifically, the present invention involves identifying microbial compositions (including phenotypic microbial compositions) of solid samples, such as cuttings or core samples, or fluid samples, such as produced or injected fluids and determining well communication or fracture height (frac height). With well communication and/or frac height analysis using microbial compositions, the operator can better plan the placement and geometry of wells in a field to maximize production and reduce the number of wells that need to be drilled to maximize that production.

Abstract: A method of separating hydrocarbons from an oil field production stream may include providing a production stream having a gas phase and a liquid phase, the production stream including oil, hydrocarbon gas, carbon dioxide, and water; substantially separating the gas phase from the liquid phase; separating the liquid phase into a stream composed substantially of oil and a stream substantially composed of water, the stream substantially composed of water containing carbon dioxide absorbed therein; pressurizing the water stream containing carbon dioxide absorbed therein; and injecting the pressurized water stream containing carbon dioxide absorbed therein to a downhole injection location; the method may include operating each step at a pressure above 150 psig.

Abstract: An earth-boring tool includes a body having a shank and a crown, a plurality of blades protruding from the crown of the body and extending at least substantially along a longitudinal length of the crown of the body, each blade extending radially outward and defining a respective radially outermost gage surface. The earth-boring tool further includes at least one rotatable cutting structure assembly including a leg and a rotatable cutting structure rotatably coupled to the leg. The earth-boring tool also includes at least one stabilizing structure secured to the crown of the body between an end of the leg opposite the rotatable cutting structure and the shank of the body, the at least one stabilizing structure being at least substantially circumferentially aligned with the leg of the at least one rotatable cutting structure assembly along a circumference of the crown of the body.

Abstract: Disclosed is an apparatus for recovering gas from an underground source of gas and water and for disposing of water from the source into a porous stratum above the source. A casing having perforations at the level of the porous stratum extends from the surface into the source. A first mandrel inside the casing is above the perforations and a second mandrel inside the casing is below the perforations. Each mandrel has a first and a second passageway therethrough. A perforated tube connects the first passageways of the first and second mandrels and a bypass tube connects the second passageways of the first and second mandrels. A first tube extends from the surface to the first passageway of the first mandrel and a second tube extends from the first passageway of the second mandrel into the source. A sucker rod extends from the surface through the inside of the first, perforated, and second tubes into the source.

Abstract: A downhole or subterranean tool for use with a subsurface strata producing both hydrocarbon gas and water in which the gas and water are separated downhole by gravity and the gas is produced to the surface through one channel, and the water is disposed into a lower subterranean disposal zone. A production tubing is suspended within a casing which lines a well bore drilled through the two zones. A sucker rod actuated reciprocating pump is located in the production tubing. A seating nipple bypass tool with longitudinal holes and side ports in the wall thereof surrounds the pump. This bypass tool is positioned between the producing zone and a lower zone which is to be used as a disposal zone for the salt water. Gas is produced upwardly through the annulus between the tubing and the casing, and the salt water is flowed down through the longitudinal tubes in the sleeve to be disposed in the lower zone.

Abstract: An acidizing composition and method for slowly dissolving siliceous material by the slow production of very low concentrations of hydrofluoric acid is provided by this invention. The continual generation of very low concentrations of hydrofluoric acid is accomplished by the hydrolysis of hexafluorotitanate-containing compounds. The acidizing composition is particularly useful and advantageous for the solubilization of siliceous clay in or adjacent the pores of subterranean hydrocarbon formations thereby increasing the permeability of said formations. Because of the very low concentration of hydrofluoric acid in the acidizing composition solubilization of siliceous clay deposits is possible at relatively large distances from the point of injection into the formation, for acidizing formations which are too sensitive for more reactive acidizing compositions, for acidizing formations containing chlorite clays, and/or for acidizing formations having an elevated temperature including formation temperatures of 125.
