A subsea heat removal system can include an inflow line having an inflow line proximal end that is connected to a pump in the water and is configured to have cooling fluid from the pump flow therethrough. The subsea heat removal system can also include a thermal transfer device having an inlet connected to an inflow line distal end, where the thermal transfer device has a thermally conductive material that is in thermal communication with an electrical device located in a wellbore. The subsea heat removal system can further include an outflow line having an outflow line distal end that is configured to be connected to an outlet of the thermal transfer device, where the outflow line is configured to have a heated version of the cooling fluid flow therethrough, and where an outflow line proximal end is located above the seabed.

An obstruction relief tool can include a plurality of walls that includes an inner wall, where the inner wall forms a cavity along a length of the inner wall. The obstruction relief tool can also include a chamber disposed between the plurality of walls, where the chamber has a proximal end and a distal end. The obstruction relief tool can further include an actuation device that is configured to actuate when an obstruction is within the cavity, where the actuation device, when actuated, is configured to open a first aperture in the inner wall that leads to the proximal end of the chamber, where the distal end of the chamber leads to a second aperture in the inner wall, where the first aperture is adjacent to the cavity above the obstruction, and where the second aperture in the inner wall is adjacent to the cavity below the obstruction.

The present disclosure provides methods and systems for hydrofracturing processes utilizing native drilling cuttings to enhance wellbore permeability. The native drilling cuttings are obtained during drilling operations and may be used in hydrofracturing applications without further grinding or processing. The native drilling cuttings can be combined into a slurry and injected into a well for the hydrofracturing application. In some cases, the native drilling cuttings are dried before combining them with the slurry.
