Cleanout tools and related methods of operation

A method of performing a cleanout operation on a well, the method comprising:

• a) lowering the cleanout tool within a casing of the well, the lowering until the cleanout tool reaches a first depth that corresponds to a first boundary of the perforations through the casing;
• b) pumping fluid from a pump at the Earth's surface into the cleanout tool such that pressure of the fluid in the cleanout tool;
• c) producing fluid streams by ports through the cleanout tool, the fluid streams intersecting an inside diameter of the casing at axial depths within the casing different than the axial depths within the casing where the fluid streams exit the cleanout out tool, the fluid streams exiting the cleanout tool provide a rotational force to the cleanout tool, and the fluid streams are pulsed;
• d) holding the cleanout tool at a rotational orientation relative to the casing while moving the cleanout tool from the first depth to a second depth that corresponds to a second boundary of the perforations, the second boundary opposite the first boundary;
• and then
• e) moving the cleanout tool to the first depth and rotating the cleanout tool a predetermined angular rotation;
• f) repeating steps b)-e) at least once.

A cleanout tool comprising:

• a tool body comprising:
• a first end, a second end opposite the first end, and medial portion, the medial portion is cylindrical and has a medial outer diameter, the medial portion has a central longitudinal axis;
• threads on the first end that have a pitch diameter smaller than the medial outside diameter;
• threads on the second end that have a pitch diameter smaller than the medial outside diameter;
• a first bore within the tool body, the first bore has a central axis coaxial with the central longitudinal axis, and the first bore defines an inside diameter along a first axial length that extends from the first end;
• a counter bore within the tool body, the counter bore defines a central axis coaxial with the central longitudinal axis, the counter bore defines an inside diameter along a second axial length that extends from the second end, and the inside diameter of the counter bore greater than the inside diameter of the first bore;
• an annular shoulder at the intersection of the first bore and the counter bore;
• an annular channel defined within the tool body, the annular channel circumscribes the counter bore, the annular channel open at the second inside diameter of the counter bore, the annular channel has a closed bottom with an inside diameter greater than the inside diameter of the counter bore, the closed bottom has a semi-circular cross-section with a radius of curvature having a center within the annular channel, and the annular channel defines side walls that intersect the inside diameter of the counter bore and form an angle of about 60 angular degrees;
• five ports through the tool body, each port has an inside aperture within the annular channel and an outside aperture through the medial outer diameter, each port defines a flow channel axis, each flow channel axis forms an angle of about 45 angular degrees to the central longitudinal axis, each flow channel axis forms an angle of about 30 angular degrees to a radial line from the central longitudinal axis through the inside aperture, and the five ports evenly spaced around the annular channel;
• a joiner coupled to the tool outer body, the joiner comprising:
• an outside surface that is cylindrical and has a central axis coaxial with the central longitudinal axis;
• a through bore that defines an inside diameter equal to the inside diameter of the counter bore;
• threads on an inside surface of the through bore on a first end of the joiner, the threads on the inside surface of the through bore coupled to the threads on the second end of the tool body;
• threads on the outside surface of the joiner on a second end of the joiner opposite the first end of the joiner;
• a sleeve telescoped within the joiner and tool body, the sleeve comprising:
• an inside diameter, an outside diameter, a first end, a second end opposite the first end of the sleeve, an end face on the first end of the sleeve abutting the annular shoulder, an end face on the second end of the sleeve, and a central axis coaxial with the central longitudinal axis;
• five ducts through the sleeve, each duct has an inside aperture and an outside aperture, each duct defines a duct axis, each duct axis forms an angle of about 45 angular degrees to the central longitudinal axis, each duct axis forms an angle of about 55 angular degrees to a radial line from the central longitudinal axis through the inside aperture of the duct, and the five ducts evenly spaced around the third inside diameter of the annular channel;
• the five ducts are disposed between the five ports;
• a locking ring within the joiner and abutting the end face on the first end of the sleeve, the locking ring;
• and
• a ball with a diameter of about two thousandths of an inch less than the difference between the inside diameter of the inner channel and the inside diameter of the counter bore.
