Heavy Mud - Sodium Bentonite


All the news from the BP oil spill talks about using heavy mud to plug the well. What is heavy mud?


A Common Clay, Swelling Bentonite.
Sodium bentonite expands when wet - it can absorb several times its dry weight in water. It is mostly used in drilling mud in the oil and gas well drilling industries. The property of swelling also makes sodium bentonite useful as a sealant, especially targeted for the sealing of subsurface disposal systems for spent nuclear fuel and for quarantining metal pollutants of groundwater. Similar uses include making slurry walls, waterproofing of below grade walls and forming other impermeable barriers (e.g. to plug old wells or as a liner in the base of landfills to prevent migration of leachate into the soil.


Why is this useful you say? Well it would be particularly useful to pour a slurry of Bentonite around a stack of cargo containers buried below grade.

Origin Oil developing a 40Ft cargo container to grow algae

Origin Oil's Complete Process


Well look how funding can help a company. Progress from Origin Oil towards making algea growing available to the masses. First they have simplified CO2 dispersion into an algal tank, then using the same process but with higher pressure figured out a way to extract the oil without using a separate ultrasonic device.



















Now they are planning on using 40 foot shipping containers as algae growing labs. The question is when can I order one and how much will it cost?http://www.originoil.com/technology/multireactor.html
