Segregated sampling technique for water samples in Uganda

Baker Hughes recently ran a series of pressure tests in Uganda where the similar salinity of formation water and filtrate indicated a segregated sampling technique after consultation with an independent oil company.

HOUSTON – Baker Hughes recently ran a series of pressure tests in Uganda where the similar salinity of formation water and filtrate indicated a segregated sampling technique after consultation with an independent oil company. 

The result was success in obtaining high quality water samples from an exploration well despite the complexities of the West African reservoir, says Baker Hughes. A total of 49 pressure tests were performed and 22 fluid samples were collected in three RCI runs. During the clean-out phases for various samples, 164 gal (622 L) were pumped and monitored during clean-up for all samples.

Besides the 22 samples, two fluid identifications were performed to confirm results from a pressure gradient in thinly laminated sections.
