Fracture-Height-Measurement System

Pinnacle Technologies, a Halliburton service, announced its FracHeight service, a hybrid tool that combines fiber-optic wireline-conveyed microseismic receivers with Pinnacle’s downhole tiltmeter sensors to directly measure the formation movement associated with fracture dilation. 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 multistage 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, the FracHeight service provides definitive evidence of fracture dilation. The result is more-accurate fracture mapping that provides insight into actual fracture deformation as a function of depth. In typical unconventional reservoirs where multistage horizontals are common, the data provided by the FracHeight service offer significant advantages for understanding fracture behavior. The improved knowledge of the subsurface provided by Frac-Height allows for optimized asset development and increased completion and fracture efficiency.
