*Production per well is much lower in the U.S. than in other countries due to subsidies for stripper wells that produce very little oil. Those subsidies are intended. A drill rig is the primary equipment used for drilling a natural gas well. It consists of a derrick, drawworks, and a rotary system. The derrick provides support and houses the drilling equipment. The drawworks control the drilling depth by raising and lowering the drilling assembly.
[pdf] It contains averages of rigs running in Louisiana divided into regions: north, south inland land, south inland water, state offshore and OCS. The main source of this data is Baker-Hughes drilling statistic.
[pdf] Ambient combustible gas detectors can be placed at various locations around the rigsite (such as the rig floor, flowline, shaker area, and pit area) to measure the levels of combustible gas in the atmosphere.
