A device for measuring strain on the exterior of a pipe includes a body comprising a top portion and a bottom portion; one or more elastically deformable members coupled between the top portion and the bottom portion, wherein each of the one or more elastically deformable members have an outer contact surface and an inner non-contact surface. One or more sensors are disposed on the inner non-contact surface of one or more of the elastically deformable members. The sensors, during use, provide data that can be used to determine changes in strain on the exterior of the pipe. In another embodiment, one or more sensors are embedded in, or attached to, a casing disposed in a wellbore. In an embodiment, a method includes pressurizing or depressurizing the wellbore with a fluid and measuring the strain induced in the casing (or in an open wellbore) in response to this change in wellbore pressure.

Downhole strain sensor

Systems and methods for assessing physical properties of a geological formation are disclosed. The systems and methods may use electrodes that include two conductive portions separated by an isolation gap positioned along a casing in a wellbore in the formation. The electrodes may be sequentially energized to provide excitation stimulus into the formation while the remaining, non-energized electrodes may substantially simultaneously receive excitation responses to the excitation stimulus from the formation. The excitation responses may be assessed to determine one or more physical properties of fractures in the formation.

Modular electrode tool for improved hydraulic fracture diagnostics

Described herein are methods and system that use electromagnetic heating to heat wellbores and the fluids therein. The heating is achieved by placing one or more permanent magnets in the wellbore and moving a metallic component and/or the one or more permanent magnets relative to each other. This generates eddy currents in the metallic component, which heat the metallic component. This heat is transferred to the fluids in the wellbore from the metallic component by convection.

Downhole induction heater for oil and gas wells

Described herein are methods and system that use electromagnetic heating to heat wellbores and the fluids therein. The heating is achieved by placing one or more permanent magnets in the wellbore and moving a metallic component and/or the one or more permanent magnets relative to each other. This generates eddy currents in the metallic component, which heat the metallic component. This heat is transferred to the fluids in the wellbore from the metallic component by convection. In some embodiments, permanent magnets are installed in the tubing to induce eddy current heating in a well by converting the linear motion of a sucker rod to rotary motion of a conducting tube using a lead or ball screw. The heater may directly integrate with existing pump jack equipment with little or no additional infrastructure required.

Methods and systems of treating hydrocarbon containing formations are described herein. A system for treating a subterranean hydrocarbon containing formation includes a wellbore, and one or more packers positioned in the wellbore. At least one of the packers allows fluid to be injected in a subterranean hydrocarbon containing formation while allowing fluid to be produced from the wellbore.
