an oil well was drilled a down hole dip-meter detemined the orentaion of each unit that was drilled the formations where dolomite, shale, sandstne, limestone, mudstone . Oil was found in the Eagle bluff limestone which was hit at a depth of 7200 ft.
I think you need to give more information. Is it asking at what depth a 2nd well would have to be drilled to? Is there a picture that goes with the question and if so can you describe it? Oil will migrate upwards until it hits an impermeable barrier, like shale.
there is a machine i've seen that creates a small local earthquake. and it acts like a giant sonigram.
Very good observation and statement. Yes, fossil fuels are normally found in limestone rich areas. As you know, oil, or crude oil, is the fossil remains of plankton, and other microbial life that rained down to the bottom of the ocean over millions of years. These deposits accumulated in areas comprised of material that eventually formed limestone caverns. This oil then had to be cooked at high temperatures to produce what we have today. So oil must be located in certain geographical areas conducive to this process. Hence, Texas, Louisiana, California, the Middle East, Etc. Locating oil is another branch of the science of engineering. Various techniques are used such as radar sounding and various methods.
they make city or cross tires for 26 rims. what it comes down to is how narrow your rims are. you shouldnt mount a tire that is narrower than your rim, as it could roll off on you. city tires are 26 tires that come in varying widths but have a smoother tread to run on pavement. you can get them as narrow as 1.25 if your rims are narrow enough to allow you to use those.
