... the northern Tarim Basin. These strike-slip fault networks are of significant importance to petroleum exploration because of their dual roles as conduits for hydrocarbon migration and fault-controlled paleokarst reservoirs. In this study, two representative strike-slip fault networks are selected for detailed...

...Olanrewaju Aboaba; Christopher Liner Abstract Mississippian paleokarst chat and tripolitic chert (tripolite) zones associated with the Mississippian Lime have been hydrocarbon exploration targets in Osage County for many decades. Chat is residual chert, either in place or transported, weathered out...

...Kristian Jensen; Martin Kyrkjebø Johansen; Isabelle Lecomte; Xavier Janson; Jan Tveranger; Tina Kaschwich Abstract Paleokarst originates from the collapse, degradation, and infill of karstified rock, and it typically features spatially heterogeneous elements such as breakdown products, sediment...

... dissolution origin for the observed HS because the paleokarst landscape also can display closely spaced, irregularly shaped negative dissolution features ( Eberli et al., 2004 ). Karsts are formed due to the dissolution and collapse of carbonate and evaporite sediments in a combination of chemical, physical...

... to delineate using traditional seismic imaging methods. Recent research on geologic characteristics of paleokarst reservoirs facilitates hydrocarbon exploration and exploitation in western China. To interpret karstic fault systems and reservoirs, the seismic image is an effective tool. A high-quality velocity...

..., and the typical stratigraphic interfaces (e.g., T 7 4 , T 7 6 , T 7 8 , T 8 0 , and T 8 1 ) were interpreted manually based on the seismic amplitude reflections. The case study area (unit TP101-TH10421) is a typical fault-controlled paleokarst reservoir located along the TP12CX strike-slip fault...

... . Paper handled by Associate Editor Andrew J. Calvert. 27 2 2018 13 7 2018 The infilling of paleokarst caves and their collapse during subsequent burial could cause large-scale changes in seismic waveforms and amplitudes ( Hardage et al. 1996 ; Loucks 1999 ; McDonnell et al. 2007...

.... Under the right conditions, the dissolution of carbonate rocks by water can develop extensive porosity ( Field, 1999 ; Wright et al., 2014 ). As such, karsts and paleokarsts represent key plays within carbonate-hosted reservoirs worldwide, namely, in hydrocarbon fields in China ( Han et al., 1998...
