Abstract: A technique facilitates multiple actuations of a toe valve system positioned along a tubing string. According to an embodiment, the toe valve system comprises a piston sleeve slidably disposed in an outer housing which has at least one port therethrough. The toe valve system also may comprise a shifting sleeve shiftable between positions with respect to the at least one port. The piston sleeve may initially be held in a position closing off the at least one port to prevent flow between the interior and exterior of the tubing string. The piston sleeve is held in this closed position via a liquid trapped in a piston chamber which is located between the piston sleeve and the outer housing. The liquid, e.g. oil, is retained in the piston chamber by a release member, e.g. a rupture disc, until sufficient pressure is applied within the toe valve system and against the piston sleeve so as to actuate the release member and to thus allow outflow of liquid from the piston chamber.

Abstract: A technique facilitates both a fracturing operation and a subsequent production operation in, for example, a geothermal well system. According to an embodiment, a geothermal a well completion is deployed downhole into a wellbore.

In some embodiments, a plurality of the shiftable tools may be used along corresponding well zones to facilitate fracturing of the well zones while also ensuring the outflow of production fluid has a desired balance along the plurality of well zones.

Abstract: A technique facilitates collecting data, related to a fracturing, run-in-hole, or pull-out-of hole operation. A frac plug is provided with electronics for obtaining the desired information related to the operation. For example, the frac plug may be constructed with electronic sensors, a digital storage device, and a power supply or other power related equipment. Depending on the application, the frac plug may be a composite frac plug, degradable frac plug, dummy frac plug, or other suitable frac plug. Retrieval of the information obtained may be done via coupling with an associated device, e.g. inductive or physical coupling, by utilizing a broadcast transmitter/receiver, by physical retrieval of the storage device, or by physical retrieval of the dummy frac plug.

Abstract: A hydraulic arrangement for fail-safe and pump-through of a safety valve. The arrangement allows for compact actuation of a safety valve through accumulators. The arrangement supports automatic closure of the valve in the emergent circumstance of any loss of hydraulic control above the valve. Additionally, the arrangement also allows for a technique of re-opening the valve for long term killing of a well in direct response to the introduction of kill fluid without requiring any added complex interventional measures.

Abstract: A method for capturing a sample from a wellbore, comprising the steps of introducing a first message and a second message into a tubing positioned within the wellbore. The first message is directed to a first modem connected to a first sampler device to cause the first sampler device to collect a first sample. The second message is directed to a second modem connected to a second sampler device to cause the second sampler device to collect a second sample.

Abstract: A technique facilitates monitoring of a location susceptible to fatigue due to loading experienced along a subsea landing string or other subsea tubing string. Initially a location or locations susceptible to fatigue may be determined along the subsea tubing string. At least one sensor, e.g. a strain sensor, is placed along the tubing string proximate the location susceptible to fatigue. The strain sensor or sensors can then be used to collect data regarding loading incurred at the location. The loading data can then be used to determine fatigue at the location and/or at a device proximate the location.

Abstract: A technique facilitates fluid flow control with respect to a fluid flowing through a component of a landing string by avoiding or protecting mechanisms otherwise susceptible to debris. A valve is provided in a well component of a landing string and comprises a flexible element. The flexible element is oriented for flexing in an inward direction with respect to an internal flow passage through the landing string. The flexible element enables selective closing off of the internal flow passage without exposing certain types of mechanical mechanisms to fluid flowing through the landing string.
