November 12, 2020 – New paper on seismic stratigraphy, seismic geomorphology, and heterogeneity of Miocene isolated carbonate platforms (Northwest Shelf, Australia) to be published soon. The high-resolution (60 Hz) seismic data permit description and interpretation of high-fidelity stratigraphic details of the initiation, expansion, termination, and geomorphology of over 100 platforms in the Langhian – Messinian interval. The data, and a review of other contemporaneous platforms, reveal that the eustatic signal combined with dynamic physical regional processes such as waves, currents, and variable subsidence to create the complex and variable architecture and geomorphology of platforms. These results illustrate how global changes can interact with local controls to create diverse patterns of birth, growth, and demise of carbonate platforms and drive local stratal heterogeneity.

July 13, 2020 – Two new publications are available in Recent Reprints for sponsors:
A new paper, “Rock Fabric Controls on Pore Evolution and Porosity-Permeability Trends in Oolitic Grainstone Reservoirs and Reservoir Analogs,” by Hamilton Goodner, Gene Rankey, Chi Zhang, and Lynn Watney, in the July 2020 AAPG Bulletin. DOI: 10.1306/12191919046. Based on Ham’s MS thesis, the project explores if and how pore evolution and Φ-k scatter quantitatively relate to depositional fabric. It empirically examined oolitic grainstones from a range of geologic ages and diagenetic histories to understand depositional sediment-pore relationships, and how they might evolve with lithification. Integrating data from point counting, digital image analysis, nuclear magnetic resonance and core analysis of Holocene, Pleistocene, Pennsylvanian, and Mississippian oolitic grainstones reveals quantitative relations among rock fabric, pores, and petrophysical parameters. Results suggest that sedimentology would control the trends or variability within an oolitic succession, but that diagenesis defines the absolute values of pore attribute metrics and petrophysical parameters. These findings suggest that petrophysical variability within oolitic reservoirs may closely follow sedimentologic trends, which may be predictable within a stratigraphic framework.
A new paper, “Chemical oceanographic influences on sediment accumulations of a carbonate ramp: Holocene Yucatan Shelf, Mexico” by Gene Rankey, Rodrigo Garza-Perez, and Hassan Eltom is now in press at Sedimentology. Although global controls on the oceanographic influences on the nature of carbonate factories are broadly understood, the details of the influences of changes in temperature and nutrients across individual carbonate shelves are less well constrained. This study explores spatial and temporal variations in chemical oceanography along and across the Yucatan Shelf, a modern carbonate ramp, and how these factors relate to variable bottom character, sediment and sediment geochemistry. In-situ ocean chemical data, remote-sensing data, bottom observations and sedimentologic and geochemical characterization indicate the sporadic presence of cool, upwelled water with low dissolved oxygen and elevated Chlorophyll-a. This current-driven, westward flow of upwelled water is most evident in sediment and geochemical attributes of a zone just offshore of the northern peninsular shoreline, but its influence wanes ca 75 km offshore and as the shore turns southward. Collectively, these data emphasize how local processes such as upwelling and longshore transport can variably influence carbonate sediment accumulations and their geochemical signatures, both along and across individual shelves. These data and insights provide an analogue for the influences of spatial variability of water masses in the geological record, and for accurate interpretation of stratigraphic changes of sedimentary and geochemical proxy data in carbonate archives.

Cyclostratigraphy has been widely applied to analysis of multiple aspects of shallow-water carbonates. Cycles at the “type locality” of carbonate cycles, the Dachstein Limestone of the Northern Limestone Alps, show limited lateral continuity and thus need for care and caution in applications of cyclostratigraphy.

August 20, 2019 – A new publication, “Rock Fabric Controls on Pore Evolution and Porosity-Permeability Trends in Oolitic Grainstone Reservoirs and Reservoir Analogs,” by Goodner, Rankey, Zhang, and Watney, is available in the sponsors section. This paper, in press at AAPG Bulletin, empirically explores relations among depositional fabric, pore evolution and Φ-k scatter within oolitic grainstones from a range of geologic ages and diagenetic histories. The integrated NMR, digital image analysis, and petrographic data provide insights into depositional sediment-pore relationships, and how they can evolve with lithification.
April 8, 2019 – New paper Effect of bioturbation on petrophysical properties: Insights from geostatistical and flow simulation modeling has just been published in Marine and Petroleum Geology. This paper, by Hassan Eltom, Gene Rankey, Steve Hasiotis, and Reza Barati, numerically models burrow networks, evaluates their connectivity, and takes the models all the way to simulation to quantitatively assess their impact on flow. The paper is available on the Recent Reprints page for sponsors.
April 3, 2019 – The full schedule for the 2019 KICC Annual Review Meeting has been uploaded. You can find it in the Sponsor Pages section.
March 4, 2019 – New publication by Regina Yayong A and others, Simulating Yield Stress Variation Along Hydraulic Fracture Face Enhances Polymer Cleanup Modeling in Tight Gas Reservoirs, is available on the Recent Reprints page for Sponsors. This work was sponsored in part by support from KICC. The manuscript details how a three-phase simulator was developed to simulate the hydraulic fracture cleanup. Results show that fluid recovery increases with shut-in time, conductivity, and fracture length. Yield stress increases proportionally to the square of the fluid loss volume. Mechanically-induced damage with hydraulic damage is the most significant. Simulating yield stress variation along the fracture, therefore, is crucial to production.
January 23, 2019 – New publication by Gene Rankey and others, Seismic architecture of a Miocene isolated carbonate platform and associated off-platform strata (Central Luconia Province, offshore Malaysia), is available free to read or download at this link until mid-March: https://authors.elsevier.com/a/1YRTAyDcGIMhx
The manuscript illustrates the internal geometry and seismic facies complexity of a Miocene isolated carbonate platform and documents interactions with flanking siliciclastics and highlights the role of syndepositional structural deformation on the carbonate system.

October 2, 2018 – Read in a new paper added to the Recent Reprints page for sponsors about a study that explores depositional influences on petrophysical variability of a tidal oolitic sand shoal. This paper, by Rankey, Goodner, and Doveton, focuses on a Pennsylvanian oolitic succession (Dewey Limestone, Missourian, Cutter Field, Kansas), describing sedimentological, geomorphical, and petrophysical attributes, and their relations. The results reveal that the distinct facies include differences in porosity, acoustic (compressional and shear) velocity, velocity anisotropy, and elastic moduli. In addition, apparent porosity exponents (ma) computed from log porosity and array induction deep resistivity reveal distinctions among facies. Geomorphological, sedimentological, and petrophysical similarities among the Dewey strata, Holocene analogs, and Pleistocene and Pennsylvanian shoals described in the paper illustrate how petrophysical trends can be influenced strongly by depositional framework and character.
August 23, 2018 – A new paper has been added to the Recent Reprints page for sponsors: To provide perspectives on syndepositional pores in ancient carbonate rocks (including aspects of pre-salt reservoirs), a new paper by Hubert et al. characterizes microbialite deposits of a Recent lake on Long Cay, Crooked–Acklins Platform, southern Bahamas. The goal of this actualistic study is to understand the influences of organic-matter source, abundance, and growth habit on carbonate depositional textures and associated pore attributes by characterizing both microscopic and macroscopic fabrics of Holocene microbialites. Results from both laboratory and field analyses at several scales indicate variation in fabric and preservation of porosity as a function of the growth habit and presence and abundance of organic matter, as well as the presence of Mg-silicates.
June 29, 2018 – One student thesis and AAPG poster have been added to the sponsor Recent Theses and Recent Reprints pages:
Erich de Zoeten, Diagenetic controls on porosity, thermal history, and hydrocarbons in the Wolfcamp A, eastern Midland Basin, Texas, M.S. thesis.
de Zoeten, E.G., Goldstein, R.H., 2018, Controls on Reservoir Quality of the Carbonates of the Wolfcamp A in the Eastern Midland Basin (Howard County, Texas): A Case for Active, Open-System Diagenesis. AAPG Poster. Description: Wolfcamp A strata along the basin margin, Howard County, eastern Midland Basin were used to evaluate the effect fluid flow on carbonate diagenesis of basinal carbonates. Stata show a complex paragenesis consisting of 31 diagenetic events. The burial stage was dominated by Permo-Triassic reflux and precipitation of calcite and anhydrite. The fracturing stage began during and after Laramide fracturing and preserved a record of repeated injection of hydrothermal fluids that had an impact on oil migration, generation, and porosity. These results show that the Wolfcamp A in this area behaved as an open system, and that Laramide structures should play a part in locating the best reservoir.

Several new manuscripts are available in the sponsors section!
Nolte, K.A., Tsoflias, G.P., Bigdoli, T.S., and Watney, W.L., 2017, Shear-wave anisotropy reveals pore fluid pressure-induced seismicity in the U.S. midcontinent: Science Advances, v. 3, e1700443 DOI: 10.1126/sciadv.1700443. The paper shows that shear-wave (S-wave) anisotropy in southern Kansas and northern Oklahoma has changed orientation over a very short period of time, interpreted to be the result of pore pressure buildup in the region. This method has the potential to provide a useful tool to industry and regulators for managing induced seismicity risk by identifying regions of critically stressed rock by elevated pore fluid pressure.
