A blender mixes a liquid and a quantity of particulate solids for use in hydrocarbon well operations. The blender is mounted on a vehicle having a suction manifold of rectangular tubing. The long side of the rectangular tubing is vertical, is positioned on one side of the vehicle and provides a large number of inlet connections which, in use, connect to hoses leading to tanks filled with a frac liquid or the like. The discharge manifold may be a mirror image of the suction manifold. The rectangular suction manifold tubing provides greater spacing between the inlet connections and greater volume throughput in use. Also, the rectangular suction manifold tubing is tilted so that the inlets are angled toward the ground.

A pair of spooled tubing strings are simultaneously run into a hydrocarbon well carrying a chamber providing a check valve. The chamber is positioned below a hydrocarbon formation so that liquid produced from the formation falls adjacent and passes into the chamber through the check valve. Periodically, gas is delivered through one of the spooled tubing strings to push liquid out of the chamber upwardly through the other of the tubing strings. Gas produced from the formation flows upwardly in an annulus between the spooled tubing strings and a production string in the well. The apparatus can be used to run only one string of tubing into a well and has a number of features, including measuring the load applied to the tubing string and measuring the amount of tubing run into or out of a well.
