A system for optimizing a geothermal heating and cooling system operation comprises a drill rig and a processor. The drill rig is configured to construct a geothermal borehole according to operational parameters and deploy a coiled tubing or joint drill pipes enabled drill bit. The processor is configured to receive user specification of (i) one or input parameters and (ii) a first coefficient of performance (COP) of a heat pump for constructing the geothermal borehole. The processor is configured to apply a model to determine the set of operational parameters for constructing the first geothermal borehole. The processor is configured to collect, in real time during the construction, sensor data from sensors positioned on the drill bit, update the model according to the sensor data, update the operational parameters according to the updated model, and control the construction of the first geothermal borehole according to the updated operational parameters.

A bottom hole assembly (BHA) operable to be conveyed within a wellbore extending into a subterranean formation from a wellsite surface via coiled tubing. The BHA may operable to receive a fluid pumped from the wellsite surface via the coiled tubing. The BHA may include a fluid control tool comprising a first fluid passage extending longitudinally through the fluid control tool and a plurality of first fluid outlets extending radially between the first fluid passage and the wellbore. The fluid control tool may be selectively operable to close the first fluid passage and open the plurality of first fluid outlets to pass the fluid into the wellbore via the plurality of first fluid outlets, and close the plurality of first fluid outlets and open the first fluid passage to pass the fluid through first fluid passage. The BHA may further include a tractor operable to move the BHA along the wellbore coupled downhole from the fluid control tool. The tractor may have a second fluid passage fluidly connected with the first fluid passage. The BHA may also include a fluid outlet sub coupled downhole from the tractor having a plurality of second fluid outlets fluidly connected with the first fluid passage and extending radially outward to fluidly connect the second fluid passage and the wellbore, and a bent sub coupled downhole from the fluid outlet sub and operable for steering the BHA.

The present disclosure relates to a wireline drum configured for use in a material handling system. The wireline drum may have a core extending between a pair of flanges. The core may be configured to receive a spooled wireline. Each flange may have a neck extending from an inner surface toward the core and configured to nestably engage the core. The present disclosure further relates to methods of manufacturing such a wireline drum. In some embodiments, each flange, including the flange neck, may be cast as substantially a single component. At a joint between each flange neck and the core, a V-shaped groove may be defined for receiving a weld. Each flange may be welded to the core at the V-shaped groove.

A method of controlling operation of equipment that spools cable on and off a rotatable drum, in one or more embodiments, includes obtaining video data of a position of the cable on the rotatable drum. The method can also include feeding data into a trained artificial neural network and processing the data fed into the trained artificial neural network to determine at least one of a calculated position of the cable on the rotatable drum, a calculated fleet angle, or both. The method can also include actuating the rotatable drum to one of spool cable on and off the rotatable drum.
