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.
May 11, 2018 – Two new papers and six new abstracts have been added to the Sponsor recent reprints page. Two student theses have also been added to the Sponsor recent theses page:

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.
