production data and other information are given in Table 4.1. As shown in the table, 56,280 <br /> gallons of water were produced in 13 hours. This is equivalent to 8.4 wellbore volumes. <br /> Early in the cleanout and production operation, large quantities of sand were produced <br /> from the wellbore and formation, but during the last five hours, the produced water was clear <br /> and essentially sand-free. This decline of sand production was probably due to the formation <br /> of sand bridges in the perforations during the relatively stable flow of the last few hours. <br /> Sand produced from the well was very clean and completely unconsolidated. Samples <br /> were collected for size distribution analysis because it appeared likely that this information would <br /> be needed for sand control design. <br /> 5.0 FORMATION WATER CHEMISTRY <br /> Samples of the Domengine formation water were collected on May 15, 1993, during the <br /> production of the well. Periodic samples were monitored in the field by three techniques to <br /> verify that the water chemistry was stable before collecting a complete suite of samples for <br /> laboratory analyses. The monitoring techniques and results are shown in Table 5.1. <br /> At 2030 hrs on May 15, the well had produced 42,840 gallons of water (6.4 wellbore <br /> volumes), and field measurements indicated the water chemistry had been stable for at least two <br /> hours. Beginning at this time, a suite of ten samples was collected for laboratory analyses by <br /> methods listed in Table 5.2. All sample bottles were washed in 10 percent (by volume) nitric <br /> acid and rinsed in deionized water before sampling. All samples except the one for phosphate <br /> analysis were stored in ice during transport to the analytical laboratory. The phosphate sample <br /> Mesquite Group, Inc. '7 <br />
