An intriguing program is afoot to assess the hydrocarbon potential of the Niobrara in south-central South Dakota. The assessment program was initiated in 2012, when the American Indian Higher Education Consortium funded a cooperative education program between the Sinte Gleska University on the Rosebud Sioux Reservation in South Dakota and the South Dakota School of Mines and Technology (SDSM&T).

The Anadarko Basin granite wash play has been considered difficult to interpret both geologically and geophysically. Consequently, the application of seismic attribute analysis to mid-continent washes has not been widely published.

Since the introduction of Electrical Borehole Images over twenty years ago many very useful applications have been developed for this data. These include applications, which range from handpicked bed dips to fracture analysis, from thin-bedded pay determination to measuring vugular porosity, from fault geometry determination to facies analysis. These applications are made possible because of the high resolution provided by these images. The images provide the means to perform detailed high-resolution reservoir characterization at the borehole. This presentation will concentrate on structural aspects of borehole image interpretation. Fault and fold examples from different basins across the USA will be examined with examples from around different US Basins.

What’s new in downhole geology, you ask? According to the advertising and press releases that are sent throughout the media, there’s a lot that’s new – more, in fact, than we could ever cover. But since this is our annual Downhole Geology issue, we thought we’d take a look at some of the latest advancements in drilling, well-logging and other downhole innovations rolled out in recent months by a few industry heavy-hitters.

This trip will visit the breathtaking coastal outcrops of turbidites, carbonate platforms, fluvial sediments and pillow lavas along the cliffs southeast of Melbourne. Come scramble down craggy slopes at Cape Liptrap to view superb outcrop-scale fold and thrust structures in Devonian turbidites, then take a 5 km hike along the adjacent coast where Cambrian ophiolites and exhumed amphibolites, faulted against trilobite-hosting Ordovician marls and Devonian reefal carbonates will be revealed. This will be followed by a trip to a site of Early Cretaceous fluvial rift sediments deposited during the initial separation of Antarctica from Australia to open the Gippsland Basin.

Whanganui, New Zealand
9-12 September 2015

This four-day trip to the internationally-significant Wanganui Basin and North Taranaki coastal sections will examine Late Miocene to Pleistocene components of shelf- to basin-floor depositional systems deposited during an overall tectonically-controlled regressive phase. We will examine and discuss the interplay between tectonics and sea-level change, and the reservoir architecture and sequence stratigraphic framework of these well-exposed rocks. The outcrop geology will be supported by a range of seismic, well and supplementary industry data.

This trip will focus on defining the Niobrara formation from the outcrop scale to the well bore, and discuss the key parameters that have made this play work, both from a geologic and a reservoir standpoint. Furthermore, we will describe how Noble Energy has helped to lead the industry in Northern Colorado to safely, responsibly and efficiently develop this huge resource. We will visit both Niobrara outcrops and Noble Energy production facilities to illustrate our current subsurface understanding and best practices.

Water cut is a big factor in gauging the success of horizontal drilling in the Mississippi Lime Play (MLP). The contributing factors are related in part to the spectrum of producing lithofacies and reservoir quality encountered that varies laterally and vertically, sometimes dramatically.
