The invention includes methods of collecting crude oil and apparatus which collect crude oil. In one implementation, a crude oil collection header apparatus includes a collection reservoir and a plurality of fluid conduits connected to feed crude oil to the collection reservoir. 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.

The invention claimed is: 1. A crude oil collection header apparatus, comprising: a collection reservoir; a plurality of fluid conduits connected to feed crude oil to the collection reservoir; the fluid conduits respectively comprising a collection reservoir feed valve, a bypass valve, and a crude oil feed inlet, the crude oil feed inlet being received in the respective fluid conduits between the collection reservoir feed and bypass valves; a bypass conduit to which the fluid conduits connect downstream of the respective bypass valves, the bypass conduit comprising a gas separator device; a flow meter conduit connected with the bypass conduit downstream of the gas separator device, a flow meter operably connected with the flow meter conduit; and a crude oil outlet associated with the collection reservoir. 2. The apparatus of claim 1 wherein the flow meter conduit connects with the collection reservoir. 3. The apparatus of claim 1 wherein the gas separator comprises a primarily liquid outlet and a primarily gas outlet, the primarily liquid outlet connecting with the flow meter conduit. 4. The apparatus of claim 3 wherein the flow meter conduit connects with the collection reservoir and the primarily gas outlet does not. 5. The apparatus of claim 1 wherein the plurality of fluid conduits join with the collection reservoir along a straight line. 6. The apparatus of claim 1 wherein the collection reservoir is elongated and substantially vertically oriented. 7. The apparatus of claim 6 wherein the fluid conduits are substantially horizontally oriented. 8. The apparatus of claim 6 wherein the plurality of fluid conduits join with the collection reservoir along a vertical line. 9. The apparatus of claim 6 wherein the collection reservoir comprises an upper end and a lower end, the crude oil outlet being proximate the lower end, the flow meter conduit connecting with the collection reservoir proximate the upper end. 10. The apparatus of claim 1 wherein the gas separator is positioned elevationally higher than the collection reservoir. 11. A crude oil collection header apparatus, comprising: an elongated and substantially vertically oriented collection reservoir having an upper end and a lower end; at least four series of a plurality of fluid conduits connected to feed crude oil to the collection reservoir; the plurality of fluid conduits within individual of the series joining with the collection reservoir along a line; the fluid conduits respectively comprising a collection reservoir feed valve, a bypass valve, and a crude oil feed inlet, the crude oil feed inlet being received in the respective fluid conduits between the collection reservoir feed and bypass valves; a bypass conduit associated with the fluid conduits downstream of the respective bypass valves, the bypass conduit comprising a gas separator device, the gas separator device comprising a primarily liquid outlet and a primarily gas outlet; a flow meter conduit connected with the primarily liquid outlet and with the collection reservoir proximate its upper end, a flow meter operably connected with the flow meter conduit; and a crude oil outlet proximate the lower end of the collection reservoir. 12. The apparatus of claim 11 comprising at least eight of said series. 13. The apparatus of claim 11 wherein all fluid conduits connected to feed crude to the collection reservoir connect with said bypass conduit comprising the gas separator. 14. The method of claim 11 wherein the line is vertical in each of the individual series. 15. The method of claim 11 wherein the plurality of fluid conduits within individual of the series are substantially horizontally oriented. 16. The method of claim 11 wherein the plurality of fluid conduits within individual of the series are substantially horizontally oriented, and the line is vertical in each of the individual series. 17. The apparatus of claim 11 wherein the gas separator is positioned elevationally higher than the collection reservoir. 18. A method of collecting crude oil, comprising: positioning a collection header apparatus within the earth lower than a crude oil-bearing strata, the collection header apparatus comprising a collection reservoir; connecting a plurality of well lines in fluid communication with the crude oil-bearing strata to the collection header apparatus; flowing crude oil at least in part by gravity from the crude oil-bearing strata through the well lines to the collection reservoir of the collection header apparatus; withdrawing crude oil from the collection reservoir; and periodically separately routing at least some of said flowing crude oil in individual of the well lines through a gas separator and a primarily liquid stream from the gas separator through a flow meter to monitor primarily liquid flow of crude oil in said individual well lines. 19. The method of claim 18 wherein at least some of the separately routed flowing crude oil in the individual of the well lines is flowed to the collection reservoir after flowing through the flow meter. 20. The method of claim 18 wherein at least some of the separately routed flowing crude oil in the individual of the well lines is flowed to a conduit downstream of the collection reservoir after flowing through the flow meter. 21. The method of claim 18 wherein the collection reservoir is elongated and oriented in a substantially vertically upright orientation. 22. The method of claim 21 comprising withdrawing crude oil from the collection reservoir proximate a bottom end of the collection reservoir. 23. The method of claim 21 comprising flowing crude oil to the collection reservoir from a conduit which is substantially horizontally oriented where it joins with the collection reservoir. 24. The method of claim 21 wherein the separately routing comprises feeding the crude oil flowing through said flow meter into the collection reservoir proximate an upper end thereof. 25. The method of claim 24 wherein the crude oil flowing from the flow meter flows to the collection reservoir from a conduit which is substantially horizontally oriented where it joins with the collection reservoir. 26. The method of claim 18 wherein the separately routing comprises opening one valve and closing another valve.
