TLDR
In this paper, the effects of carbonate diagenesis, especially pressure solution during relatively shallow burial stages, exercise major controls on the processes of petroleum generation and migration during deeper burial.About:

Primary Migration by Oil-Generation Microfracturing in Low-Permeability Source Rocks: Application to the Austin Chalk, Texas
Robert R. Berg,Anthony F. Gangi +1 more
TL;DR: In this article, an equation for the pressure change in low-permeability source rocks is derived using four major assumptions: (1) the permeability of the source rock is negligibly small (0.01 µd; 10-20 m2) so that the pore-pressure buildup by the conversion is much faster than its dissipation by porefluid flow; (2) the stress state is isotropic so that horizontal and vertical stresses are equal.

Geological and geochemical characterization of the Lower Cretaceous Pearsall Formation, Maverick Basin, south Texas: A future shale gas resource?
TL;DR: In this paper, the authors evaluated the Lower Cretaceous Pearsall Formation of the Maverick Basin, south Texas, as a potential shale gas resource and estimated a mean undiscovered technically recoverable natural gas resource of 8.8 tcf of gas and 3.4 and 17.8 Tcf at the F95 and F5 fractile confidence levels, respectively.

Impact of stylolitization on diagenesis of a Lower Cretaceous carbonate reservoir from a giant oilfield, Abu Dhabi, United Arab Emirates

TL;DR: In this paper, the authors demonstrate that stylolitization plays a crucial role in fluid flow and diagenesis of carbonate reservoirs during basin evolution, and the flanks of the oilfield (water zone) display more frequent presence and higher amplitude of stylolites, lower porosity and permeability, higher homogenization temperatures and more radiogenic composition of carbonates compared to the oil zone.

Petroleum Migration: Mechanisms, Pathways, Efficiencies and Numerical Simulations
Ulrich Mann,T. Hantschel,Rainer G. Schaefer,Bernhard M. Krooss,Detlev Leythaeuser,Ralf Littke,Reinhard F. Sachsenhofer +6 more
TL;DR: In this article, the authors discuss the aspects of petroleum entrapment, redistribution in traps and petroleum loss from traps, and various types of traps in a special case of petroleum migration in which an otherwise diffuse fluid flow field is highly focussed towards a reservoir structure.

Deposition of petroleum source rocks
TL;DR: It has been long recognized that fine-grained sediments of both siliciclastic and carbonate compositions are the principal source rocks of petroleum as discussed by the authors, and the common coincidence of significant, and often high, content of organic matter within such sediments, as first comprehensively documented by Trask and Wu (1930), provided the initial clue and support for this now generally accepted opinion.

Middle East: Stratigraphic Evolution and Oil Habitat
TL;DR: The post-Hercynian sequence of the Middle East is dominated by carbonate sedimentation on a stable platform flanked on the northeast by the Tethys ocean as mentioned in this paper, and three principal types of depositional systems alternated in time: (1) ramp-type mixed carbonate-clastic units and (2) differentiated carbonate shelves.
