Nonplanar Fracture Propagation From a Horizontal Wellbore: Experimental Study

Abstract: Summary This paper presents experimental results related to hydraulic fracturing of a horizontal well, specifically the nonplanar fracture geometries resulting from fracture initiation and propagation. Experiments were designed to investigate nonplanar fracture geometries which were categorized as: multiple parallel fractures, T-shaped fractures, and reoriented fractures. This paper discusses how these nonplanar fractures can be responsible for premature screen out and excessive treatment pre… Show more

“…The rough fracture opening surface and the failure of a mini-fracture linkup from deviated wellbores were reported by Hallam and Last [6], Veeken et al [7], Weijers and de Pater [8]. The propagation of a hydraulic fracture from oriented perforation was also studied experimentally by El Rabaa [9] and Abass et al [10,11]. The experimental observation is in general consistent with the analytical results presented in this section.…”

“…This reorientation results in a tortuous and segmented fracture path, as evidenced by pressure losses that can be interpreted from the injection pressure records (Weijers et al 1994). Specifically, the large pressure losses are reflected in the drop in pressure that occurs at shut-in (Abass et al 1996) and by direct measurement of the difference between the injection pressure and the pressure in the fracture measured by an offset monitoring borehole. Lecampion et al (2013) provide a concise summary of the literature dealing with reorienting hydraulic fractures.…”

“…Since the hydraulic fracturing procedure is a flow-deformation coupling process, the fluid flow changes the stress state in rock and the stress reversely influences the fluid flow. The major difference of this pore pressure from the bottom hole pressure obtained in the field (Jeffrey et al 1995), or indoor experiments (Abass et al 1996), is that there is a sudden increase and it slightly drops to a stable value. This is because it is the real time pore pressure simulated within the rock and exhibits a different phenomenon (Ji et al 2009, Morgan et al 2015.…”
