B. [10 pts] Two separate aquifers, one confined, one unconfined, have an equal porosity of na0.22,...
4. (30 pts) Table below listed some reading information from the log, please determine Rw using Rwa method assume that at least one of the three zone is water zone Determine the water saturation for each zone If the water saturation and porosity cutoff, shale volume are 45% and 15%, 20% respectively. The initial formation volume factor Boi-1.25 rbbl/stb and the drainage area is 100 acres, please determine the net pay thickness and oil-in-place. Notes, the formation is limestone formation...
Question 5: (25 marks) A fully penetrating pumping well is located in a confined aquifer that can be considered to have an infinite extent in all directions. There is no recharge to the aquifer and no other pumping wells in the area. There are two observation wells located at 100 and 500 m, respectively, from the pumping wells. The aquifer and the pumping well have the following properties: Depth to top of aquifer: 50 m Aquifer thickness: 5 m Aquifer...
2. A significant new source of water in the form of two aquifers was recently discovered in the dry northern region of Turkana in Kenya, East Africa where a significant population lacks access to safe water. As background information, the aquifers contain nearly 250 billion cubic meters of water (66 trillion gallons) and are recharged at a rate of 3.4 billion cubic meters (898 billion gallons) each year. The recharge rate is how much water goes back into the aquifer...
Question 4 of 10 If two separate containers A and B have the same volume and temperature, but container A has more gaseous molecules than B, then container A will have:
2. If two solutions of equal volume, one saturated with CrPO. (Ksp = 2.4 x 10-4) and the other saturated with Ca(103)2 (K. = 1.0 x 10-) are mixed, will Cas(PO4)2 precipitate? The K. of Cas(PO4)2 is 1.3 x 10-32 You may assume that each solution contains no undissolved solids prior to mixing: {7 marks) Hint: Don't forget that when the two solutions are mixed, their volumes are combined!
The sediments that formed the Nubian aquifer system are much older than those of the High Plains aquifer system or the sediments of Bangladesh. The oldest rocks in the aquifer are Cambrian in age (541 to 485 million years old). After deposition, these sediments were buried, compacted, and cemented, and lithified to form sedimentary rocks. Two cross sections are shown. The sands that form the sandstones were deposited by rivers and wind in nearshore (beach) areas. The sandstone is distinguished...
Problem 4 (10 points) A pipeline with two pumps (Pump A and Pump B) in series delivers water between two tanks with a total static head of 50 ft. The pipeline is 8 inches in diameter and 5000 ft in length, with a Darcy- Weisbach friction factor f = 0.025. The total minor head loss coefficient Ek 20. The characteristics of the two pumps are shown in the following table. Determine (a) the operating conditions of head and discharge, (b)...
Electrolysis of water forms diatomic hydrogen and diatomic oxygen in a two to one ratio as described in the chemical equation. 2H,0 + 2 H, + 0214 Calculate the moles of both diatomic hydrogen and diatomic oxygen formed from electrolysis of 25.0 moles of water. Each gas was collected in separate pistons that expanded against a pressure of 1.00 atmosphere and were maintained at a constant temperature of 298 K. Using the ideal Gas Law and the moles of each...
Volumetric Reserves Estimation The Stock-tank Oil Initially in Place (STOTIP) is the amount of oil that is stored in an oil reservoir. Assuming that the pore spaces in the reservoir are filled with water and oil only, the STOTIP can be estimated using the formula: STOLIP = 7758Ah (1 - S..)/B where A is the area of the reservoir in acres, h is the reservoir thickness in feet (ft). s is the initial water saturation of the reservoir. It is...
not the firsf picture. only the second QUESTION 1 Two glasses with equal quantities of water are at the same temperature. if the temperature of one is ralsed by 10 C and that of the other is raised by 10K, which one will be hotter? O The temperature of the first glass is more than the second, as each degree on the Celsius scale equals 1.8 degrees on the Kelvin scale. - The temperature of first glass is more than...
