Abstract: The invention includes methods of collecting crude oil and apparatus which collect crude oil. In one implementation, a crude oil collection header apparatus comprises a collection reservoir. A plurality of fluid conduits is connected to feed crude oil to the collection reservoir. The fluid conduits respectively comprise a collection reservoir feed valve, a bypass valve, and a crude oil feed inlet received between the collection reservoir feed and bypass valves. A flow meter conduit is connected with multiple of the plurality of fluid conduits downstream of the respective bypass valves. A flow meter is operably connected with the flow meter conduit. A crude oil outlet is associated with the collection reservoir. Other aspects and implementations are disclosed.

The fluid conduits respectively include a collection reservoir feed valve, a bypass valve, and a crude oil feed inlet received between the collection reservoir feed and bypass valves. A bypass conduit to which the fluid conduits connect is received downstream of the respective bypass valves. The bypass conduit includes a gas separator device. A flow meter conduit is connected with the bypass conduit downstream of the gas separator device. A flow meter is operably connected with the flow meter conduit. A crude oil outlet is associated with the collection reservoir. Other aspects and implementations are disclosed.

Abstract: A drill pipe elevator includes first and second separable pieces. Each piece comprises a drill pipe-receiving groove, and a pair of diametrically opposed projections with each projection forming only part of a pair of diametrically opposed lifting posts. The first and second separable pieces when positioned together define the pair of diametrically opposed lifting posts from the pair of diametrically opposed projections and define a drill pipe-receiving passageway through the drill pipe elevator that is oriented transversely between the lifting posts.
