Cleaning the environment from the dirty oil

I watched amazing documentary film about Mega structures: Black gold fields on National Geographic Channel Abu Dhabi. Extraction of the petroleum deposit in Canada required Mega structures. Oil sands will be the future of the oil industry. Shell challenge Syncrude in better production, but Shell system for extraction oil from sands uses large amount of water, producing waste water. Officially they use this water for planting wood, but the trees required long time to grow and use this large amount of the waste water. what make me blog this post is Shell environmental engineer opinion: look at the bright side! we are cleaning the sand from the oil, we cleaning the environment from the dirty oil!!

Aquifers Properties: Porosity (n)

Image
Aquifers Properties: Porosity (n) The porosity of a soil or rock is that fraction of a given volume of material that is occupied by void space, or interstices. Porosity, indicated by the symbol ( n ), is usually expressed as the ratio of the volume of voids. Most rocks naturally contain a certain percentage of voids that can be occupied by water. Fig. 1 Porosity (n)

The Biggest Mistakes Made by Geotechnical Drilling Companies in Saudi Arabia The recession in Saudi Arabia affecting all type of business. Oil price dropped and the country entered the Yemen war. Small geotechnical drilling companies made some mistakes to survive the current recession. Some of small companies did not  survive  and they closed/sold their business. below are the biggest mistakes:

Aquifers Properties: Specific Yield and Specific Retention

Image
Aquifers Properties: Specific Yield and Specific Retention In an aquifer with a water table (unconfined aquifer), the volume of water released from groundwater storage per unit surface area of aquifer per unit decline in the water table is known as the specific yield, S y . also known as the drainable porosity. Hydrologists divide water in storage in the ground into the part that will drain under the influence of gravity (called specific yield) and the part that is retained as a film on rock surfaces and in very small openings (called specific retention). The physical forces that control specific retention are the same forces involved in the thickness and moisture content of the capillary, fringe. fig.1
