SST’s 36” test well is tied into a full ﬂow loop in order to facilitate surface ﬂow testing. The ﬂow loop is equipped with three centrifugal pumps which together are capable of ﬂowing, 50 bpm or 72,000 bpd.
The system typically ﬂows either water or gelled ﬂuids at ambient temperature. However, the ﬂuid reservoir can be cooled down with its 75 ton chiller, thus allowing long-term ﬂowing at a stable temperature. The test well itself can be heated up to 400°F via a glycol heating system that ﬂows through the well casing.
The ﬂowrates in the system are measured by either low or high ﬂow turbine ﬂowmeters (0.5 bpm to 60 bpm). The ﬂow meters are placed both upstream and downstream of the well with the data being displayed on rate totalizers and with analog input.
Sand or other solids in the ﬂow stream can be measured with a sophisticated system of both ultrasonic and with our inﬂow camera solids detection systems, which can detect particles as small as 25 um (microns). Solids are then caught in a large ﬁlter/strainer unit which uses ﬁlter socks of varying size to prevent particles from recirculating and causing any damage to the system.
