Mushrooms Image via Wikipedia The White Desert is located at the northern region of the Farafra Oasis . I had visited it within field trip to western desert. The white desert has been classified by government of Egypt as a natural protected zone in 2002 and covers an area of 3010 square kilometers. It's far 570 km from Cairo. The White desert is a unique geological phenomenon; where wind and water erosion sculptured their way through the soft chalk forming incredible shapes "Mushrooms". Along the road Baharia - Farafra, the main geological observations as many isolated hills and hillocks consisting almost of massive bedded, snow white chalk of Maastrichtian Khoman Formation. There are many fascinating geomorphologic feature accompanied the carbonate rocks of the plateau surface such as cave deposits and onyx,

There was some questions in my mind when i start my blog, How to make a good blog? How to blog? What is the best style for science blogging? I got some good answer lately, I think it's useful enough to share it here with sci bloggers who want know the answer or have answers of the following questions. What is the best blogging service for scientists (Blogger, Wordpress, tumblr, or Posterous etc.)? Obbie King : The best blog for a scientist (or anyone, for that matter) is the one that that particular person finds most comfortable to work with and that most effectively communicates the content he/she is presenting. I would suggest "playing around" with some of the more popular platforms, look for ways to make it "look" the way you want, and decide which platform makes you feel more comfortable. You then may wish to get help from someone who's well-versed in your chosen service to set up the fine details and get you rolling.

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

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)

Lost Circulation is one of the major drilling problem geologists and drilling engineer’s struggling it while drilling a well for both oil/gas and groundwater. If a very porous, cavernous or highly fractured zone is encountered while drilling; an excessive amount of drilling mud is lost to that zone during lost circulation. The zone is called a thief or lost circulation zone. In this case I’ll explain dilemma I faced while drilling groundwater well in North Sinai, Egypt we expecting the aquifer at 1200m. Within drilling community North Sinai distinguishing by repetitive Lost Circulation. I joking with my colleagues we need to invent (Lost Circulation Preventer) instead of (Plow out Preventer). That lead me to design Excell worksheet to make cement job calculation easy work , because I think every repetitive work should has a system to make it done. The following table is the important data about lost circulation zones: Depth(m) Lithology/comment From to 372 404 Dolomite, ...

http://youtu.be/zxbiNWSNPTk After watching this movie, my personal opinion about 2012 Ice Age is the most stupid science fiction movie I have ever seen; everything is not realistic. Even the main idea (declares war on the glaciers) is not realistic. I think this movie show the ‘next ice age’ as a theory in a bad way to promote global warming theory. #BadGeologyMovie

This my first post to  Accretionary Wedge Geoscience Blog Carnival . The current topic for AW#35 is “ What's Your Favorite Geology Word? ” hosted by Evelyn Mervine . My Favorite Geology Word Is - Isopach Definition: A contour that connects points of equal thickness. Commonly, the isopachs, or contours that make up an isopach map, display the stratigraphic thickness of a rock unit as opposed to the true vertical thickness. Isopachs are true stratigraphic thicknesses; i.e., perpendicular to bedding surfaces.( Source ) Pronunciation:  'ī-sə-ˌpak Date:  approximately 1918 Structure map includes an isopach of the reservoir with contours shown in red dashes. Venezuela Well Evaluation Conference, 1997, page 2-26 Source: http://www.glossary.oilfield.slb.com/ Isopach is a Map of the thickness variation of a stratigraphic unit; used in geological exploration for oil and for underground structural analysis.  I always love to draw it due to it's...
