Oil Drilling Rig

The Oil Drilling Rig is a multiblock Machine in GregTech 5 Unofficial for pumping oil needed for plastics or as fuel.

Building the Multiblock
First Build a base of 3x3 Solid Steel Casings. The controller goes into the middle of one side. It also needs an Energy Hatch, Maintenance Hatch and an Output Hatch.

After that, place 3 more Solid Steel Casings on the middle of the base.



Finally place 3 Steel Frames on top of and to each side of the 3 middle Casings.



Once the Multiblock has formed, resolve the issues via the maintenance hatch.

Usage
Place Mining Pipes in the Oil Drilling Rig block. You can't actually see a slot to put the Mining Pipes into, shift-clicking on the pipes in your inventory will help you to find the right spot to put them. The drill will start digging down until it reaches bedrock. After that it will start pumping the oil contained in that chunk.

An Oil source is 96x96 blocks big. 50% of these areas are empty. The others each have a chance of 12.5% to contain Natural Gas, Light Oil, Oil, Heavy Oil. Oil sources do not vary in the amount of oil contained, but rather the speed it can be pumped out. The speed is random beween 1-1024L/cycle. One cycle is 8 sec long using LV. With IV a cycle is down to 0.5 sec. Only 2% of all sources produce more than 500L/cycle, 4% more than 250L/cycle.... After some time pumping the speed slowly drops until it finally reaches 0.

You have to find your first oil for plastic by randomly drilling. Once reaching HV tech, it is possible to build the Seismic Prospector to search for oil more efficiently.
