Abstract: A tubular handling apparatus includes a plurality of pipe beams defining a pipe rack, a plurality of tiering arms, each having a first recess, and a plurality of lifting arms. Each lifting arm corresponds to one of the plurality of tiering arms and each lifting arm includes a second recess proximate a first end of each of the lifting arms. Each second recess is aligned with a first recess of a corresponding tiering arm. The plurality of lifting arms are actuatable between a raised position and a lowered position relative to the plurality of tiering arms. A top surface of each of the plurality of pipe beams includes a slope extending downward towards the plurality of tiering arms. As the lifting arms raise, the tubular is lifted from the tiering arms and rolls along the top edge of the lifting arms until the tubular engages with the second recess.

Abstract: A drill rig may include a motor connected to a piston-diaphragm pump configured to: apply a force to a fluid in a cylinder of the piston-diaphragm pump by moving a piston in the cylinder, the fluid filling a void inside the cylinder between a head of the piston and one side of a diaphragm; transfer the force from the fluid across the diaphragm to a drilling mud by flexing the diaphragm, where the drilling mud is separated from the first fluid; and cause a flowrate of the drilling mud through a value connected to the cylinder via a high-pressure piping system into the borehole. The drill rig may direct the mud through a kelly and a pipe to a bottom of the wellbore, force the mud through nozzles located near a bit, rotate the bit, and returning the mud through an annulus to the surface.
