Abstract: Biogenic sulfide production is synergistically inhibited by treating sulfate-reducing bacteria (SRB) with a biocide and a metabolic inhibitor. The biocide directly kills a first portion of the SRB. The metabolic inhibitor inhibits sulfate-reducing growth of a second portion of the SRB without directly killing the second portion of the SRB. The treatment of SRB with both a biocide and a metabolic inhibitor provides effective biogenic sulfide inhibition at significantly lower concentrations than would be required if the biocide or metabolic inhibitor was used alone.

Abstract translation: 通过用杀生物剂和代谢抑制剂处理硫酸盐还原菌（SRB）来协同抑制生物硫化物的生成。 杀生物剂直接杀死了SRB的第一部分。 代谢抑制剂抑制SRB的第二部分的硫酸盐还原生长，而不直接杀死SRB的第二部分。 用杀生物剂和代谢抑制剂处理SRB可以以比单独使用杀生物剂或代谢抑制剂所需的浓度低得多的浓度提供有效的生物硫化物抑制。

Abstract: Radio frequency radiation is introduced downhole to heat one or more components of an in-situ hydrocarbon mixture. The mixture is heated to a temperature conducive to auto-ignition. Upon heating, an oxidant is introduced at conditions supportive of auto-ignition. The combined oxidant/hydrocarbon mixture is then allowed to auto-ignite and combust to form a partially upgraded mixture. Certain embodiments include introducing an ignition agent to facilitate auto-ignition. The radio frequency radiation may be supplemented, continued, or varied as desired to maintain, facilitate, or manage the resulting combustion process. In some cases, an activator is introduced to the formation to interact with the generated radio frequency radiation to enhance hydrocarbon heating. Advantages of certain embodiments include lower cost, reduced heating/ignition equipment, higher efficiencies, increased hydrocarbon recovery, and fewer auto-ignition failures.

Abstract: This invention relates to drilling a well, particularly an oil or gas well, where casing or liner will be installed to stabilize the wellbore. The present invention is intended to permit more drilling and longer lengths of casing or liner to be installed at one time. The present invention includes a combination of a smear tool and specially sized granular lost circulation material solids in the drilling mud which work together to close and seal leaking formations and fractures whether pre-existing or induced by drilling. By the natural collection of the inventive solids along with the conventional particles in the drilling mud to form a filter cake at the problem areas along the wall of the wellbore and the smear tool arranged to compress the filter cake into the problem areas, lost circulation is minimized. Maintaining circulation naturally allows for longer drilling cycles and potentially fewer liner joints in the well. As such, larger diameter boreholes are located in the hydrocarbon bearing formation and less time is spent installing casing or liner pipe.

Abstract: Systems and methods generate steam in hydrocarbon recovery operations and may further enable emulsion separation and product upgrading. The methods rely on indirect boiling of water by contact with a thermal transfer liquid heated to a temperature sufficient to vaporize the water. Examples of the liquid include oils, recovered hydrocarbons, liquid metals and brine. Heating of the liquid may utilize circulation of the liquid across or through a furnace, heat exchangers, or a gas-liquid contactor supplied with hot gas. Further, a solvent for bitumen introduced into the water may also vaporize upon contact with the thermal transfer liquid.

Abstract: A method of event location to avoid first break picking when signals are small or the ambient noise level is high is described. In this method traveltime associated with the maximum amplitude phases (for any mode of wave) are identified and picked from one or more sensors in an array. Difference between the arrival times are then calculated. A grid search (or optimization) techniques are then employed to search for the event location to match the observed time differences.
