Abstract: Systems and methods for removing carbonaceous clinker material from a coke oven are described. A coke oven can be provided including an oven floor, coke, and clinker material deposited on the oven floor. After a temperature of the coke oven has reached a first temperature (e.g., after heating coal in the oven to produce coke), the method includes increasing the temperature of the coke oven to a second temperature that is higher than the first temperature for a predetermined amount of time. After the predetermined amount of time, the temperature is reduced to a third temperature that is lower than the first temperature.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: Diesel oil-based invert emulsion drilling fluids having fragile gel properties and improved performance. Methods are also disclosed for drilling, running casing, cementing, and/or producing hydrocarbons in a subterranean formation.

Abstract: An inhibitive water-based polymer mud system and method for using the system in drilling and in stabilizing wellbores is disclosed for use in water sensitive formations as an alternative to oil-based muds. The system comprises a non-ionic low molecular weight polyacrylamide in combination with a non-ionic high molecular weight polyacrylamide, preferably long chain alcohol and poly anionic cellulose.

Abstract: A sweep material is disclosed comprising barium sulfate that has been ground and sieved, preferably in the range of about −95% 30 mesh to about +95% 100 mesh. The sweep material is added to and circulated with the drilling fluid during drilling of a deviated, directional or horizontal well to remove cuttings beds accumulated on the lower side of the well. After the drill cuttings are dislodged, the drilling fluid is sieved or screened to remove the barium sulfate to avoid a change in density of the fluid. The drilling operation does not have to be stopped during the sweep or cleaning treatment.
