3 Mechanical Stratigraphic Controls on Fracturing (Jointing) and Normal Faulting in the Eagle Ford Formation, South-Central Texas, U.S.A. David A. Ferrill, Ronald N. McGinnis, Alan P. Morris, Kevin J. Smart, Zachary T. Sickmann, Michael Bentz Southwest Research Institute, San Antonio, Texas Daniel Lehrmann Trinity University, San Antonio, Texas Mark A. Evans Central Connecticut State University, New Britain, Connecticut 3

4 Introduction Natural fracture systems influence production in unconventional reservoirs Mechanical layering and in situ stress strongly influence natural and induced fracturing Eagle Ford Formation is mechanically layered and naturally deformed Eagle Ford productive trend includes contractional and extensional structural styles Improved understanding of these factors is leading to better well planning and stimulation design 4

30 Failure Modes From Ferrill & Morris (2003), Journal of Structural Geology 30

31 Hybrid and Shear Failure Hybrid failure (mode 1.5) in chalk beds Shear (mode 2) failure in mudrock beds Crack seal texture indicates multitude of reactivation events each producing porosity Ferrill et al. (2014), AAPG Bulletin 31

32 Hybrid Failure Ferrill et al. (2014), AAPG Bulletin 32

33 Hybrid Failure Ferrill et al. (2014), AAPG Bulletin 33

34 Hybrid Failure Failure surface shows evidence of hybrid failure (mode 1.5) in chalk beds Calcite fibers grow in direction of displacement on shear (mode 2) surfaces in adjacent mudrock beds Ferrill et al. (2014), AAPG Bulletin 34

35 Fault Refraction Mode switching Mode 1 to mode 2 Mode 1.5 to mode 2 Change in shear failure angle (mode 2) From Ferrill et al. (2012), Journal of Structural Geology 35

36 Fault Slip and Dilation Shear failure in mudrock Hybrid failure in chalk Crack-seal textures indicate incremental opening in response to multitude of slip (reactivation) events Dilational zones are self-propping Shear Hybrid Shear Ferrill et al. (2014), AAPG Bulletin 36

37 Stress History Stress inversion based on fault measurements Ferrill et al. (2014), AAPG Bulletin 37

38 Fluid History from Calcite Veins Fault zone veins from Sycamore Creek Pavements Fluid inclusion microthermometry, fluid inclusion UV fluorescence, and O and C stable isotope analysis Fault zone calcite precipitated by several isotopically different fluids Smaller displacement faults more likely to have single fluid source Crack-seal texture indicates numerous (10s to 100s) events Ferrill et al. (2014), AAPG Bulletin 38

39 Fluid History A Source fluids for veins was not meteoric water but formation water Low salinity inclusions suggest meteoric mixing to dilute the fluids Abundance of hydrocarbon inclusions in the veins indicates that liquid hydrocarbons were ubiquitous B Ferrill et al. (2014), AAPG Bulletin 39

40 Fluid History Stable isotope values of vein calcite are significantly different from host rock indicating an open fluid system Elevated homogenization temperatures suggest trapping of aqueous fluids 2 km deep Faults likely formed at depths equivalent to some present-day oil and gas production from the Eagle Ford A B Ferrill et al. (2014), AAPG Bulletin 40

41 Conclusions Mechanical layering strongly influenced fracturing Faults cut multiple layers refract through mechanical layers dip more steeply in competent layers formed as hybrid fractures in chalk formed as shear fractures in mudrock dilated along steep segments with each slip event 41

42 Conclusions Joints bed restricted best developed in chalk beds terminate vertically in mudrock layers have much greater lateral extent than vertical penetration 42

43 Conclusions Abutting relationships indicate the following sequence 1 st Normal faults 2 nd NE-striking joints 3 rd NW-striking joints Faults at Sycamore Creek pavements formed at 2 km depth Fault zone calcite veins indicate precipitation from formation water, fluid mixing, and movement of liquid hydrocarbons Joints formed during subsequent erosional unloading 43

44 Conclusions Natural fracture systems, mechanical stratigraphy, and in situ stress conditions are the context for hydraulic stimulation Natural fractures are pre-existing weakness likely to reactivate before conditions for failure of intact rock are reached Open or mineral filled faults and extension fractures have contrasting porosity and permeability with respect to host rock layers, and may dilate, slip or compartmentalize fluid pressure increase during stimulation Outcrop structures serve as analogs for induced hydraulic fractures 44

45 Finite Element Model of Induced Hydraulic Fracturing Shows Complex Damage Horizontal Layering with Normal-Faulting Stress State at depth of 3 km (~9,800 ft): 1 = V = 60 MPa; 2 = H = 50 MPa; 3 = h = 40 MPa; P = 30 MPa Pore Pressure Contours & Principal Stress Axes Shear Damage & Max. Extension Directions Model domain is vertical section parallel to lateral wellbore at base. Mechanical stratigraphic layering strongly controls (i) stress state and pore pressure evolution, and (ii) damage and strain patterns Smart et al. 2014, AAPG Bulletin 45
