The present invention discloses a method and apparatus for a well testing or production facility system. More particularly, but not by way of limitation, the invention discloses a method and apparatus to transfer crude oil from a separator to an oil pipeline, or alternatively, to a burner flare. The method includes collecting oil in a separator, and then transferring the oil to a first, second, and third pump cylinder. The oil is sequentially forced from the cylinders by high pressure gas, and after being drained, the cylinders are again filled with crude oil. The apparatus includes a separator, a first, second and third pump cylinder which will sequentially receive crude oil. Sensing means are associated with the pump cylinders for sensing the level of crude oil within the cylinders. A control system is utilized to cycle a high pressure gas or air into each of the cylinders in order to force the oil out of the cylinders.
