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.

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.
