"fracture extent" is a correct phrase in written English.
It refers to the size or severity of a fracture or break in something, usually in reference to bones but can also be used in other contexts. Example: The doctor examined the X-ray to determine the fracture extent of the patient's broken arm.
The hydraulic fracturing design coding was done for two different types of fracture extent namely vertical fracture and horizontal fracture.
Case 2 The well B was drilled at depth 10,000 ft with the fracture gradient of 0.64 ft/psi and assumed to be in vertical fracture extent.
Since the well depth is at 7,000 ft, the fracture extent of the well is assumed as vertical with the fracture gradient of 0.7 ft/psi.
The PR of the well after fracturing was 5. Case 4 The type of fracture extent is vertical as the well was drilled up to 6,500 ft with the fracture gradient of 0.68 psi/ft.
Understanding the fracture extent is important not only for assisting with hydraulic fracture design, but also for mitigating unwanted fracture growth into non-target geologic intervals that do not contain hydrocarbons (e.g. zones with high water saturation).
We derive a number of limiting solutions for hydraulic fracture propagation assuming that the flow occurs in a given regime over all the fracture extent: turbulent smooth or turbulent rough.
In API (2009), the fracture extents are divided into two which consists of horizontal fracture and vertical fracture The fracture plane in productive layer is assumed to be vertical when the fracture gradient is 0.7 psi/ft of 2,000 ft depth or less, and horizontal when the fracture gradient is 1.0 psi/ft of 2,000 ft depth or greater.
The data from the WHI study are the most robust non-vertebral fracture data extent.
Randomization was stratified for hip or other fracture, and extent of undernutrition.
We anticipated the presence of clinical heterogeneity, based on the findings that the effects of surgery seemed to vary depending on the type of fracture, the extent of metaphyseal comminution, the quality of the bone, and the medical condition of the patient (Cherubino et al. 2010).
The severity of the injury is determined by the location of the stress fracture and the extent to which the fracture propagates across the involved bone.
