Abstract: Well casing heads are provided that can include: a housing defining a first opening at the first end and a second opening at the second end, the first diameter of the first opening being greater than the second diameter of the second opening; and at least one fluid passageway extending through a wall of the housing and into the second opening. Well casing systems within a wall of an underground platform are also provided. The systems can include: a well casing head; a pair of tubular members about each other extending from the well casing head into a wall of the platform; and a void between the two members, the void extending from within the underground platform to the at least one fluid passageway of the well casing head. Methods for removing fluid from earth about an underground platform are also provided.

Abstract: Well casing assemblies are provided that can include at least one casing extending between two ends; another casing surrounding the one casing and extending between the two ends, the one and the other casing defining a void there between. Well casing systems within a wall of an underground platform are also provided. The system can include a pair of tubular members about each other extending upwardly from within the platform into a wall of the platform. Methods for setting casing in an underground platform are also provided. The methods can include extending a well upwardly to within a wall of the underground platform and providing fluid cement to within the well. The method can further include curing the cement to form a casing within the well.

Abstract: Disclosed are hydrocarbon recovery drill string apparatus, subterranean hydrocarbon recovery drilling methods, and subterranean hydrocarbon recovery methods. In one embodiment, a hydrocarbon recovery drill string apparatus includes an elongated assembly within which a rotatable drill rod is received. The assembly comprises a longitudinal axis, a drill rod entrance end, and a drill rod exit end. The assembly comprises a tailcuttings diverter pipe proximate the drill rod exit end, with the tailcuttings diverter pipe defining an initial fluid flow path of the tailcuttings from the longitudinal axis which is acute from the longitudinal axis. Other apparatus and method aspects are contemplated.

Abstract: A subterranean method of processing a hydrocarbon fluid-containing deposit includes, from a subterranean room, providing a borehole into a deposit containing formation fluid comprising fluid hydrocarbon. The borehole has a first end at a wall of the subterranean room, and a second end remote from the subterranean room and received within the deposit. The first end is elevationally lower than the second end. A string of pipe is provided within the borehole from the subterranean room. A cuttings removal fluid is injected from the string of pipe into the borehole and against a wall of the borehole in underbalanced pressure conditions. One of drilling, reaming, or jetting is conducted within the borehole during said injecting of the cuttings removal fluid. Formation fluid comprising fluid hydrocarbon is flowed from the deposit into the borehole during said injecting of the cuttings removal fluid.
