**Step-drawdown Test on MX Well**A step-drawdown test was conducted on the MX Well in southern Spring Valley in September 1980. The radius of the well casing is 5 inches, and the radius of the well and gravel pack is 7 inches. The well was drilled to a total depth of 700 feet below the land surface and is screened from 559 to 679 feet below the land surface. The static water level in the well is 231.36 feet below the land surface. Each pumping step lasted for 3 hours, with times and observed drawdowns shown in the table below.| **Time of Operation** | **Pumping Rate (gpm)** | **Depth to Water at End of Cycle (feet)** ||-----------------------|------------------------|------------------------------------------|| 10:00 am – 1:00 pm | 210 | 235.62 || 1:00 pm – 4:00 pm | 392 | 239.39 || 4:00 pm – 7:00 pm | 550 | 242.75 || 7:00 pm – 10:00 pm | 583 | 243.46 |**Tasks:**a. Estimate the transmissivity of the well, assuming it is a confined aquifer with a storativity between 10^-5 and 10^-3.b. Calculate the efficiency of the well at 200, 400, and 600 gpm.

3b) A well of r = 0.328 ft , drainage area 650 acres and Pwr=4500 psia in the reservoir of following characteristics (K = 28 md, h = 59 ft, Pe= 5651 psia, u = 1.67 cp, and B, 1.12 rb/stb). This well is producing at steady state with an outer boundary constant pressure of 5651 psia. This well suffers from skin effect equals to + 10 and penetration of damage is 3ft beyond the wall of the well. Answer Following Questions: A) Calculate production rate of the well for s =+10 and s = zero. B) Describe two mechanisms to increase damaged well production by 30% C) Permeability of damage zone.
Please use the table to answer the second question
Can you calculate the concentration at the end of the well using the 1-D steady advection-dispersion-reaction equation. The given parameters are distance = 200 m, Initial concentration = 10 mg/L, reaction = 0.0062 / day, dispersion = 1.5 m^2/d, and velocity = 0.5 m/d.
