Abstract: A septum contains at least one internal chamber along the central axis of the septum. The chamber provides relief space into which the sealing sections of the septum can deform as a needle passes through the septum. Incorporation of the chamber reduces surface area contact and friction between the septum and needle, which results in reduced septum tearing and reduced production of particulate matter from abrasion.

Abstract: Provided is a diagnostic wellbore testing method that includes forming a diagnostic wellbore in a subterranean zone including one or more formations. The wellbore extends through a portion of a formation having a maximum horizontal stress extending in a first direction and a minimum horizontal stress extending in a second direction perpendicular to the first direction. The method also includes forming a pair of notches on a circumference of the wellbore. The pair of notches are formed diametrically opposite each other. The method also includes applying fluidic pressure to the wellbore at the pair of notches in the second direction while avoiding applying fluidic pressure in the first direction. Fractures propagate from the pair of notches responsive to the fluidic pressure. The method also includes measuring a closure pressure of the wellbore, and providing the closure pressure as the maximum horizontal stress of the formation.

Abstract: A method of securing a wellbore experiencing upward crossflow includes determining a depth of a leak in a first wellbore casing tubular and identifying a second wellbore casing tubular downhole of the leak depth. From a surface, a well control tool is incrementally lowered into the wellbore until a lower tool string of the well control tool is positioned in mating contact with an end receptacle of the second wellbore casing tubular. The lower tool string is exposed to the upward crossflow during lowering of the well control tool. A unidirectional valve preinstalled inside the lower tool string inhibits movement of the upward crossflow into an upper tool string of the well control tool while permitting kill fluid pumped into the upper tool string from the surface to flow into the wellbore. The unidirectional valve is retrieved to allow additional operations in the wellbore through the lower tool string.
