Hello Earth! here I'll wonder about geology and science. I'll try to blog weekly to share my love of geology with others. I hope you find my posts interesting, enjoy reading. :)

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 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
Colors on Geologic Time Scale or on Geologic Maps form a problem to all geologists around the world, there are many standards in color. I'll not speak about the history of colors or the culture behind the difference in colors, Geologic maps rely on color to symbolize the different ages of rocks. same area can be mapped in different colors, and you can use one or two reference to geologic time scale. USGS have standards and BGS have another standards, it's not the problem of 'Colors' and 'Colours' . When biologists made one DNA standards, they work on the Human Genome Project to mapping the Human genome , the complete code of the human genome is one of the best science achievements. All Geologists need one standard for the geological time scale, or for Geologic Maps whatever it's source (origin) or it's culture. one standard is important for many scientific reasons.
