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] *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.

Drilling derricks and Rig Masts consist of a steel framework with a square or rectangular cross-section. Their purpose is to support the hoisting equipment and rack the tubulars while tripping pipe. The number of joints in a stand (single-double-triple) that the rig can pull is dependent on the height of the derrick. .
The Drawworks is one of the most important components of the drilling rig (types of drilling rigs). The unit supplies the hoisting power, the. .
The Crown Blockas a drilling rig component is a fixed set of pulleys (called sheaves) located at the top of the derrick or mast, where the drilling line is threaded. The companion blocks to these pulleys are the traveling blocks. By using two sets of blocks in this fashion,. .
The Traveling Blockis a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the. .
Attached to the bottom of the traveling blocks, the hook is required to hang the swivel and rig kelly(for drilling) and the elevator bales (for tripping pipe and casing).
