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.
Hydraulic fracturing or FRAC is a well stimulation technique utilised in conventional and unconventional reservoirs to increase the productivity of a well. It involves the injection of a proppant, sand or other non-compressible particles suspended in a gel at high pressure to fracture the formation. This process creates a series of permeable channels connecting the formation to the borehole and allowing fluid to flow at higher rates. Evaluating the effectiveness of the FRAC is a challenge because there is no tool or service able to provide three-dimensional measurements. Current evaluation methodologies include expensive acquisition techniques, such as micro-seismic survey, and hazardous and inconclusive techniques, such as radioactive tracers. TGT's Spectral FRAC Flow (SPEC-FRAC*) is designed to measure the effective flow of a fracture zone tracing the path of produced or injected fluid. 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.
