Abstract: A method for determining a flow distribution of a wellbore during a wellbore treatment comprises disposing an optical fiber into a wellbore, performing a wellbore treatment in the wellbore with the fiber optic in place by flowing a well treatment fluid from the surface and wellbore and into the formation, taking distributed temperature measurements at a time interval with the fiber optic cable during the wellbore treatment operation, and calculating a flow distribution of the wellbore while performing the wellbore treatment.

In certain embodiments, a priori data may be used to automatically generate a pull test plan or schedule. In addition, in certain embodiments, real-time data may be used to automatically and/or manually adjust or fine-tune the pull test schedule. In addition, in certain embodiments, an application may automatically generate a pull test schedule and/or automate one or more pull tests. In addition, in certain embodiments, the application may automatically advise a coiled tubing (CT) operator regarding where and how to pull test in substantially real-time.

Abstract: A system for managing multiple transmissions over a single fiber optic thread at an oilfield. The system includes surface equipment and a downhole device coupled to the equipment by way of the fiber optic thread. The types of transmissions may be telemetric or even optical power. Additionally, the transmissions may be one-way or two-way in nature between the equipment and the downhole device. Additionally, unique platform layouts may be employed for sake of managing different transmission types in different ways, for example, during coiled tubing operations.

Abstract: Systems and methods presented herein facilitate operation of well-related tools. In certain embodiments, a variety of data (e.g., downhole data and/or surface data) may be collected to enable optimization of operations related to the well-related tools. In certain embodiments, the collected data may be provided as advisory data (e.g., presented to human operators of the well to inform control actions performed by the human operators) and/or used to facilitate automation of downhole processes and/or surface processes (e.g., which may be automatically performed by a computer implemented surface processing system (e.g., a well control system), without intervention from human operators). In certain embodiments, the systems and methods described herein may enhance downhole operations (e.g., milling operations) by improving the efficiency and utilization of data to enable performance optimization and improved resource controls of the downhole operations.

Abstract: Methods of performing a stimulation operation at a wellsite are disclosed. The wellsite is positioned about a subterranean formation having a wellbore therethrough and zones thereabout. The method involves establishing at least one objective for stimulating production of reservoir fluid from the subterranean formation and into the wellbore. The stimulating involves placing a stimulating fluid along the zones of the wellbore. The objective is based on wellsite data. The method also involves identifying at least one constraint for the stimulating, determining target distributions of the stimulation fluid based on the objective(s) and the constraint(s), and selecting operational parameters for the stimulating based on the constraint(s) and the target distributions. The method may also involve stimulating the subterranean formation using the target distributions and the operational parameters, monitoring the wellsite during the stimulating, and adjusting the stimulating based on the monitoring.

Abstract: Systems and methods presented herein facilitate coiled tubing operations, and generally relate to conveying, via coiled tubing, a downhole well tool into a wellbore extending through a hydrocarbon-bearing reservoir, and performing a plurality of downhole well operations (production operations, perforation operations, testing operations, clean out operations, and so forth) using the downhole well tool. In general, the plurality of downhole well operations may be performed using the downhole well tool while maintaining full well control and without removing the downhole well tool from the wellbore.

Abstract: A sour production fluid mitigation system may at an entry point below an injection sub for a coiled tubing system, pumping an inhibited fluid through pressure control equipment for the coiled tubing system to an exit point. A sour production fluid mitigation system may use a choke guide below the exit point and above a wellhead, maintaining an inhibited fluid pressure at the exit point greater than or equal to a production fluid pressure at a production tree of the wellhead.

Abstract: A technique facilitates controlled creation of pressure waves in a downhole environment. The technique enables creation of, for example, dynamic underbalance (DUB) pressure waves or dynamic overbalance (DOB) pressure waves which can be used to perform desired activities downhole. According to an embodiment, a pump is coupled with a pressure chamber and conveyed downhole into a borehole to a desired location. The pump may be operated downhole to change a pressure level in the pressure chamber until a sufficient pressure differential exists between an interior and an exterior of the pressure chamber. A release mechanism in communication with the pressure chamber is then rapidly opened to establish the desired pressure wave as the differing pressures equalize.
