Gate paper is having two type of questions. 1) MCQs (Multiple Choice Questions) 2) NAT (Numerical Answer Type) GATE is having good portions of questions in NAT sections. To get a good score it is important to know how to tackle with NAT questions. You can not win with only answering Multiple Choice Questions. Here are tips for NAT questions. 1) In NAT questions, if you don't know method to solve, then try to guess answer. Try to guess answer in logical manner with smart way.  Just say if some one asking you positive prime number less than 10 and you don't know answer, but you have given range in question itself. You can atleast write any number between 1 to 10. 2) Atleast type/answer the NAT questions based on logical range of thing asked in quetion. Eg. If they are asking probability of something then you know basic thing it will be in between 0 to 1. Then you have range in which you can answer. Next step is, look at question and try to guess whether it will be more than any n

 GATE allows virtual key board to use during examination. You will just have to click on calculator icon, and calculator will be displayed on your screen board.  You can only take help of mouse and not key board. So practice accordingly. Try to solve problems from GATE virtual calculator only so that on exam day you don't feel it troublesome. display of virtual calculator is like as shown in image. You can find offline virtual calculator from clicking on this following link: GATE virtual calculato r  Procedure to use GATE Virtual Calculator: 1)   Simple Arithmetic Calculations: To calculate 7*(2+3) 7*(2+3) 2) For  Eg. for tan(2 degree) ( Similar for sin, cos operations also) tan(2 degree) 3) For Log or ln operations Eg. for 1*log(3) + 2 1*log(3) + 2 4) for e to the power anything Eg.  e 2 e 2 5) For n factorial (n!) Eg.  (5!)*3-4 (5!)*3-4 6) For valuate nth power of any number: Eg.  8 4    (same for, nth root also) 8 4 7) for log with base Eg. for log 2 (base 10) for log 2 (base 10

To get rid of any problem in life, there is always two ways. One you research your problem, find root cause of problem and remove the root cause and second is, Ingore the problem and perform more better with alternative ideas or innovations. Let's say, you are always late for your office or school, that's problem. And you investigate that it's because of trafic signal delay on your way to office or school. Then you can have two ways. One, You can make your plan accordingly so that you will not arrive at red signal while crossing signal and other one is you change the route of your travel. Here first one is removing root cause and later one is Ignoring problem and finding other way   Same thing happen in our reservoir and production engineering also. When problem of formation damage occurs, there are to ways to get rid of it. One is removing original problem after finding why our formation is damaged. In this method, we use technique like Matrix acidization which removes the

Porosity and permeability are two basic petrological properties of rock. Porosity is basically, void space within rock mateiral.(pores, channels, vugs or fractures or anything which is not rock grains) So, we can imagine porosity as, 'storage capisity of rock.' If you have closed container filled with sand and you spray it with water. Then it will absorb some amount of water into it. Thats the porosity.  Mathematically porosity is volume fraction of void space with respect to bulk volume. Porosity is described as percentages. Many people has mis conception that porosity depends upon grain size. Which is wrong. Porosity is independent of grain size. Porosity depends on grain sorting and not on grain size. For types of  porosity : Click here . And Absolute Permeability is ability of rock (not fluid) to pass fluid through it. Remember, it is ability of rock and not fluid.  Permeability of rock shows us, how easily rock can pass fluid through it. If Permeability of rock is more, th
