Origin, distribution and implications on production of bedding-parallel fractures: A case study from the Carboniferous KT-Ⅰ Formation in the NT oilfield, Precaspian Basin, Kazakhstan

Bedding-parallel fractures (BPFs) are the breakage of rocks along weakness bedding plane of stratification or foliation. At present, the research of fractures is primarily focused on high-angle structural fractures (SFs), but few systematic efforts have been made on the formation mechanism, distribution and influences on oil production of BPFs. Knowledge of attributes of BPFs in carbonate reservoirs is necessary for well-site design and reservoir waterflooding development.
