Pinnacle Technologies, a Halliburton service, announces its latest innovation in fracture diagnostics. FracHeight™ service is a hybrid tool that combines fibre optic wireline conveyed microseismic receivers with Pinnacle’s downhole tiltmeter sensors that directly measure the formation movement associated with fracture dilation.
Fracture mapping in unconventional reservoirs
While microseismic monitoring has been the primary diagnostic tool for fracture mapping in unconventional reservoirs, determining fracture height can sometimes be a challenge when relying on these measurements alone.
For example, in some multi-stage fractures where shallow microseisms clearly exist, identifying the cause – be it the actual fracture opening, natural fractures, a result of a critically stressed zone shearing, or some other mechanism – requires additional information. By incorporating microdeformation measurements made by downhole tiltmeters, FracHeight service provides definitive evidence of fracture dilation. The result is a service that leads to more accurate fracture mapping by providing insight on actual fracture deformation as a function of depth.
Understanding fracture behaviour in unconventional reservoirs
In typical unconventional reservoirs where multi-stage horizontals are common, the data provided by this new service offers significant advantages for understanding fracture behaviour. The improved knowledge of the subsurface provided by FracHeight service allows for optimised asset development and increased completion and fracture efficiency.
