Abstract:
To optimize the efficiency of a perforating tool system, downhole conditions may be simulated to determine the optimal configuration for the perforating tool system. A simulated wellbore is disposed in a pressure vessel and coupled to a target composite core assembly. A perforating tool system is disposed in the simulated wellbore above the target composite core assembly. The target composite core assembly includes an outer shell. The outer shell comprises a material that supports a rubber bladder or flexible jacket that is disposed about the outer shell. The outer shell isolates the overburden fluid and pressure from the inner core during a radial flow test to more accurately simulate conditions downhole. A parameter of a perforating tool system may be altered based, at least in part, on a result from the radial flow test.
Abstract:
Viscosity assemblies may be used to determine the viscosity of a sample fluid at a surface location under one or more downhole conditions prior to pumping or flowing of the sample fluid downhole. A viscosity assembly may include a bob assembly disposed in a container that includes a bob disposed about a magnet rotor that rotates when a shear force is applied by the flow of the sample fluid in the container. A stator coil may receive a control signal that induces a force or a voltage that causes the magnet rotor to rotate the bob by a predetermined distance to position the bob from the rotated position back to the initial position.
Abstract:
Undetected emissions may damage devices at a work site and pose a safety hazard to the surrounding environment. A method of control based on predictive emissions detection is disclosed. The method uses sensors coupled to work site equipment to identify devices and regions of a work site that may be affected by adverse conditions. Detection of such emissions may allow the system or operator to shut down or otherwise act on equipment before any harm is done to the device or personnel in the area.
Abstract:
A sensing system may comprise a deployment device having an optical fiber cable with a predetermined curvature or an intrinsic curvature. The sensing system may be deployed into a location that is remote or difficult to navigate, for example, a large vessel or a borehole of a well. A deployment device may deploy the optical fiber cable and a tension control tool may maintain the deployment device along with the optical fiber cable in a straight or non-curved shape until the optical fiber cable has reached a predetermined location or position. A force may then be applied to the optical fiber cable to cause a portion of the optical fiber cable to contact an interior wall of the area or location, for example, a borehole or the deployment device. Measurements may be retrieved from the optical fiber cable, for example, measurements used in distributed acoustic sensing in vertical seismic profiling.
Abstract:
Contamination estimation of a mud filtrate or reservoir sample requires a robust handle on the properties of mud filtrate at downhole conditions. Coupling acquired data with downhole measured data provides a robust estimation of contamination by encompassing the entire available data. Downhole density of the mud filtrate sample may be estimated based on a characteristic of the mud filtrate sample. A density of a formation fluid of the reservoir may be determined using a formation tester tool. The contamination of the formation fluid may be estimated based on the clean fluid density and the estimated mud filtrate density by, for example, using a material balance equation or ratio. An estimated pump-out time for the formation fluid may be determined based on the estimated contamination and a trend of the estimated contamination of the formation fluid.
Abstract:
Methods for delivering treatment chemicals into a subterranean formation using treatment fluids that include nanoemulsions are provided. In some embodiments, the methods include providing a treatment fluid including an aqueous base fluid and a nanoemulsion including a water-soluble internal phase, a water-soluble external phase, and a surfactant, the nanoemulsion being formed by mechanically-induced shear rupturing; and introducing the treatment fluid into at least a portion of a subterranean formation at or above a pressure sufficient to create or enhance at least one fracture in the subterranean formation.
Abstract:
The present disclosure relates to methods and systems for using elastocaloric materials in subterranean formations. A variety of downhole packages, for example, electronic packages and instrumentation packages, are utilized in subterranean formations during hydrocarbon exploration and production operations. Downhole packages are typically designed to operate below a maximum temperature. When a downhole package is placed in the subterranean formation, its temperature may increase as a result of the natural temperature of the subterranean formation in which it is being used. Additionally, many of these downhole packages used downhole generate heat during operation which may raise the temperature of the downhole package. Reaching or exceeding the maximum temperature of a downhole package may result in ineffective operation and/or complete destruction of the downhole package. As a result, the downhole package may need to be frequently replaced. Furthermore, additional steps may be needed to ensure the temperature in the subterranean formation does not exceed the design temperature of the downhole packages and/or to cool downhole packages prior to being introduced into the subterranean formation.
Abstract:
Certain conditions require powering down an engine driving a pump. During the down sequence the pump may continue pumping servicing fluid which may not be desirable. Activating one or more control valves may throttle or prevent the servicing fluid from being pumped from the pump during the power down sequence. Activation of an input control valve may introduce pressurized fluid into a cylinder of the pump extending a rod to force or maintain a suction valve in an open position. While the suction valve is in the open position, the stroke of the plunger may not create enough pressure to pump the servicing fluid causing the servicing fluid to flow between a fluid header and a chamber of the pump. Activation of an output control valve may divert servicing fluid pumped from the pump to a reservoir instead of to the desired location.
Abstract:
Electrically ignitable and electrically controllable explosive material (EIECEM) may be disposed within a shaped charge for deployment downhole. An explosion of the EIECEM is controlled by limiting the duration of excitation at the EIECEM, for example, the duration that an electrical source provides an electrical charge, electrical current or electrical signal. The shaped charge may be insulated from an electrical source to prevent explosion of the EIECEM and coupled to the electrical source to create ignite or explode the EIECEM. A plurality of shaped charges may be disposed downhole and may be ignited or exploded in any suitable order. The EIECEM may be ignited multiple times such that multiple explosions are created. The explosion of the EIECEM creates or extends a perforation or fracture in a formation. The shaped charges may be arranged to create a shaped perforation or fracture, such as a slot-shaped fracture.
