A cellar around a wellbore is formed or deepened with an excavating system that is capable of being assembled around an existing wellbore. The system includes an excavating unit having an annular body with a cutting surface that excavates cuttings from ground around the wellbore. The cuttings are directed up through a slot in the body, and are collected inside a receptacle set in a recess of the body. An opening is formed in a side of the receptacle when in the body, and through which the cuttings pass from the slot into the receptacle. The receptacle is removable from within the recess and cuttings collected within are emptied. When the receptacle is removed from the recess, the opening is automatically covered to retain the cuttings inside the receptacle. Another cellar around a different wellbore is formed by disassembling the excavating system and relocating it to the different wellbore.

Disclosed is an apparatus (100) for sub-surface injection of constituents of a slurry, wet mixture, and or gas in a phase of entrainment for controlled flow. The apparatus (100) includes a rotary union (113), a drilling assembly (403), hollow shaft injection drilling arrays (1003A), limit switches (1705, 1707, 1709), and encoders (1605B). The rotary union (113) facilitates the filling of the constituent in hollow shaft drilling bits (129) during a drilling process or before the drilling process via an opening and closing of a plurality of valves (111, 215, 505B, 805B, and 1107B). The constituents are capable of being injected through the rotary union, wherein the rotary union (113) is in concert with the valve (111) to dispense predefined quantities of constituents at a specific depth in a sequence of dispersal. The drilling assembly (403) is directed by a GPS (1413C) to control an X plane and Y-plane injection coordinates. The drilling assembly (403) determines through a PLC (1405C), a computer (1411C), and an AI robot (1505) in concert with achieved depths of the Z (cubic) volume of injected material. The hollow shaft injection drilling arrays (1003A) provide the sequential dispensing of the constituents at one or more targeted depths, wherein the hollow shaft injection drilling arrays (1003A) enable capturing of targeted volumes of constituents thereby creating mono or poly constituent horizons. The hollow shaft injection drilling arrays (1003A) are enabled by the limit switches (1705, 1707, 1709), the encoders (1605B), and the AI robot (1505) to sequence the constituents to be injected at specific depths.

An articulated support for mast devices of drilling machines, as well as a relative drilling machine, which allows the mast device to rotate by more than 90° from one side to the other with respect to a direction of advancement of the drilling machine is disclosed. The articulated support comprising includes a main body and two rotating bodies, first and second, pivoted to the central body along a same axis and one independently from the other. A linear actuator is pivoted on the main body and is configured to rotate the first rotatable body with respect to the main body around this axis of rotation. Another linear actuator is pivoted on the first rotatable body and is configured to rotate the second rotatable body with respect to the first rotatable body about this axis of rotation. The second rotatable body includes a support to fix a mast device.
