Clastic zone. Fissure. The main parameters for distinguishing fissure is THL and GVR images by well. As it discussed previously the cut off for fissure is less than 20ft, based on well data. Secondary distinctive parameter is resistivity image, the fissure does not have a structure, and mainly it is perpendicular to wellbore and has a rugged surface, usually conductive. According the observations fissures can be filled with sand or clay, and mixed. The figures #39 and #40 shows the distance from surface of shaly and sandy fissures. As you see from the figures, there is no difference between clean sand and shaly sand fissures in distance to top Shuaiba surface. The main message that fissures are mostly sand filled, that might create a high permeability zones in Shuaiba. Figure #14 shows the non-scaled distribution along the wellbore fissures, based on well data the average THL of fissure 8ft, and thickness around 80ft, which means the distribution of clastic zones in Shu9A. There is an one evidence when fissure with a high permeability, based on …show more content…
The pressure pre-test at 10,851 ft. MDRT is in a sand filled fissure which also had depletion and fits with the depletion profile observed along the well indicating possible communication between the Shuaiba and Nahr …show more content…
And there is no doubt that feature detected in the Shuaiba the well trajectory confirms. According the dimensions iron rich zones considered as a fissures, on GVR images structurally also crossing Shuaiba perpendicular, but all of them conductive, looks like due to heavy mineral content. On the Figure #18 shown distribution of iron rich zones and it is clearly seen that most of iron rich intervals are correlates with fault. Taking that observation in consideration was presented 2 concepts of origin of the iron rich

Tectonic plate movement can occur as close as two and up to 450 miles below the Earth’s surface. According to the Indiana Geological Survey, Indiana’s fault lines are further underground than those in California and Alaska, causing more minor quakes in the Midwest. However, Hoosiers should heed the recent earthquake as a warning for future quakes. Earthquakes can and do happen in Indiana, and almost anywhere else in the world. This is the one natural disaster that people cannot avoid no matter their location on Earth. And, being unprepared can have devastating results.
purpose we use this for is to drill wells into so that we may obtain the water that
The San Andreas Fault Line, first identified in 1895 by Professor Andrew Lawson of UC Berkeley, is an 800-mile fracture in the Earth’s surface, stretching from the Gulf of California to San Francisco, and is one of the longest faults in the world. It forms the boundary between the Pacific Plate and the North American Plate, with a complex network of smaller faults branching off the main San Andreas line which are responsible for a majority of the areas earthquakes.

Recently in the Bismarck Sea there have been discoveries of rich minerals imbedded in the sea floor such as gold, lead, cobalt, silver, copper and zinc. We only have a short time left of gold, 16 years. There are several volcanoes located around the Bismarck Sea, which means there are many mineral deposits coming out from under the sea floor leaving deep pockets rich in coal and minerals. As the tectonic plates are moving they are activating volcanic eruptions, releasing minerals into the sea floor. With the tectonic plates continuously moving, the minerals and metal ores are shifting into the sea floor pockets causing the volcanoes to erupt coal and ores. The edge of the tectonic plates run directly under this site, subsequently releasing minerals from the magma below into the ocean floor.

There was many different theories people had came up with to try and rationalize the situation. Some people say that it had something to do with the Earth’s tectonic plates splitting apart, while others thought otherwise. My own and favorite theory was something along the lines of Yellowstone geysers blowing up. Still, all I know is that some serious shit must have happened in order for most of the countries to be split apart.
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
inferred for the reservoir (4). The magma ascent to the surface occurred through a conduit of possibly 70 to 100 m in diameter (5). A thermal model predicts that such a reservoir should contain a core of partially molten magma (6) that can be detected by high-resolution seismic tomography.
