For example, the scatter of logged head from a test ",here the transducer was outside its conduit, at the pump inlet and with a free hanging pump column was not significantly different to that from another test where the transducer was set inside a perforated conduit, 4m above the pump inlet, and where the pump column was centralised. The effectiveness of various configurations used need to be n,-affirmed under conditions other than those available during this series of tests. The worst scatter encountered varied from the compared to the site (RN 20544) differed. order of 300mm at the 3m scatter found at the original test site HcNillans Road test where pump setting, rate and bore construction The only controllable factor found to influence the vibrations using a helical rotor type pump was the pump speed. separate series of tests The Nindata and Unidata This was examined in detail through a on bore RN 20544 (see Reference 18).

Hono 620 pump with 50mrn column, set at 40m below ground vlaS used for these tests. The tests were designed initially to determine whether the pump motor or shaft speed were variables associated with the "scatter" of data. If so, then a working range of speeds should be determined so that these could be specified to produce a scatter of data to within acceptable limits. In one test the pump shaft speed was kept const~e,nt at 3 different engine speeds (using the gearbox). In the test "HH'IEST1" the engine was run at three different speeds in each of four gears (Refer Figure 3.6). 22.214.171.124 pumped Bore Results (Electric Submersible P'.l11lps) Two systems, a Mindata and a Wesdata were trialled in a bore pumped by a "Multi-Motor" submersible pump.
