Reservoir characterisation and understanding reservoir fluid dynamics is fundamental for effective reservoir management. Identifying active formation zones, distinguishing fracture and matrix flows, and understanding fluid movement from the reservoir to the wellbore is essential for optimal recovery
TGT’s Spectral Reservoir Platform (SRP*) is able to diagnose reservoir problems away from the wellbore, through multiple strings and deep in the reservoir. Our range of logging services can provide real reservoir answers for up to 5 m (15 ft) away from the borehole. These answers include: fluid breakthrough identification, injection and production profiling, stimulation efficiency evaluation and formation pressure determination behind multiple casings.
Conventional production logging has been a conventional technique to analyse fluid production or injection for any well. This information is valuable as it explains the dynamics of the fluid produced or injected through a set of perforations or a production interval within the wellbore. However, conventional production logging is limited to the wellbore and, therefore, does not provide tangible information on fluid flow from the reservoir. TGT's Spectral Reservoir Flow Analysis (SPEC-RFA*) measures noise generated by fluid movement behind multiple completion strings deep in the formation enabling the detection of cross-flows and other flow anomalies impacting the well performance. Passive high-definition acoustic data (SNL-HD*) and high-precision temperature (HPT*) data used with TGT's proprietary modelling software (TERMOSIM*) allows quantifying reservoir flow.
