Expectations, pilot testing

The PSM pilot test will begin in three weeks, on May 15 we expect to maintain it for six to eight weeks to ensure that we get full benefit of this exercise. At the end of this period, the Facility Managers Council will review what has been learned, recommend any changes needed, and report our findings to senior management. 

It s reasonable to expect that you will need to generate interim reports on the pilot test. Such reports would logically include discussion of progress to date, organized to include the key indicators you have been monitoring. In addition, you may wish to include other topics, such as ... 

Launch. We initiated the pilot on schedule on May 15 with a series of group orientation meetings with all three shifts at Marwood. Members of the Task Force, plus the facility manager, conducted these meetings, where we explained the PSM system, discussed the pilot test, and outlined expectations of Manwood personnel. 

With each use of (necessarily) conservative assumed data, the precision of the estimate is diminished. Field pilot testing is an effective way to generate valid data for input into the models. When natural attenuation is selected as the best option, continued monitoring for 3 to 10 years should be expected. 

This reaction over vanadia catalyst showed much better selectivity than before. At 823 K the selectivity exceeded 70%. This result was recognized as a promising lead to a long awaited direct process. However, a pilot test did not meet expectation since the selectivity proved to be too low for commercialization of the process. 

Wetting For operation at low liquid loads, the onset of minimum wetting can adversely affect scale-up, particularly with random packings and aqueous systems. Scale-up reliability at low liquid loads can be improved by pilot-testing at the composition range expected in the prototype, and by using identical packing materials and surface treatment in the pilot tests and in the prototype. 

Any relevant process factors (Sec. 7.3.6) are allowed for. Also, it is a good policy to pilot-test over several composition ranges engulfing all those expected in the commercial column. A pilot test is never an exact replication of a commercial column, and differences may lead to poor scaleup. 

Wu and Chen (167) recommend pilot testing over the entire range between the expected minimum and maximum operating rates, and taking the highest measured HETP as the basis for scaleup. The author concurs. With structured packings, the loed effect may be due to liqnid rather than vapor loads, and the pilot tests should cover the range of liquid loads (i.e., gpm per square foot of column cross section) that is expected in the prototype. 

Perform pilot tests over the entire range of vapor and liquid loads between the expected minimum and maximum operating rates. UBe the highest measured HETP as the basis for scaleup. 

The test arrangement is shown diagramatically in Fig. 3. The upper end of the specimen is screwed into a strain-gauged PMMA Hopkinson bar of 19 mm diameter and 1.5 m length, calibrated for short-time response. Pilot tests had shown that the craze lifetime under impact lay within the expected uniaxial stress wave return time of 1.2 ms. 

A major source of uncertainty in costing a voucher scheme is the proportion of recipients who redeem their vouchers. If too few recipients use their vouchers, the resulting health or other benefits may be smaller than expected. Furthermore, the lower the redemption rate, the higher the distribution costs in relation to the outputs achieved. The best way to estimate the likely redemption rate is to perform a pilot test (see chapter 6). 

The pilot test included 10 injectors, 16 producers, 2 observation wells, and 2 wells for coring. Before the test, the water cut was 97.4%, and the recovery factor was 34.3% with the expected waterflooding recovery factor of 36.3%. The residual oil saturation was 0.33, and the average sweep efficiency was 0.54. The injection pressure was about 11.9 MPa (1725.8 psi). 

There is currently limited field experience with SSD for a smaller range of prodncts. This database is expected to increase significantly in the coming decade. In the mean time, more pilot testing is recommended for an SSD application. 

P(2) If the prediction of the relevant calculation models, or the failure mode to be expected in the tests, is extremely doubtM, the test plan shall be developed on the basis of accompanjdng pilot tests. 

Inaccessible pore volume has a beneficial effect on field performance. The bank of connate water and polymer-depleted injection water that precedes the polymer bank will be reduced by the amount of inaccessible pore volume. Polymer response will be seen at production wells sooner than expected for example, a pilot test reported by Jones found polymer in the produced water immediately after breakthrough. Because adsorption is unchanged, the total polymer treatment cannot be reduced, but the income acceleration benefits of earlier response can be substantial. 

The success criteria definition used for Stage 1 is not as simple as that of the entire pilot test (the general objective previously described). Actually, Stage 1 is expected only to partially achieve specific objectives. In an early pilot test phase, the key issue is the determination to continue to the second stage. To move to the second stage, the following criteria mnst be demonstrated ...
