Explorer Historical Highlights

This is the story of the drilling of a costly ($60 million) Lahee A-1 well in the Colombian foothills, which presented significant deviations from the prognosticated stratigraphy halfway to the objective – and became an operational nuisance. Nonetheless, it is mainly a story of successful management and prompt response to the geological uncertainty.

The Wattenberg Field north of Denver has become a big deal in the industry since its discovery in 1970 by Amoco Production Company. It’s a twofer, kicking out both oil and natural gas. To many, mention of the field conjures up thoughts of the upper Cretaceous Niobrara shale, which is a prolific producer there, along with other geologic formations. The Codell sandstone, for example, is a major pay in this giant field.

Crude oil and natural gas infrastructure problems, from pipeline oil spills to train derailments and fires, have been in the news recently. Though these problems are not new, public concern is growing. Think tanks and government agencies have been considering the problems and potential solutions for some time and are now reporting the results of their studies. Here are reports of one oil and one natural gas infrastructure study.

Deltas are extremely important depositional systems and often source and contain prolific hydrocarbon accumulations. This workshop includes topical lectures, key cores, and a suite of exercises that integrate core, well logs, experimental flume data, and seismic sections to develop identification and subsurface mapping skills of hydrocarbon accumulations within deltaic settings.

VG Abstract

Analysis of microseismicity induced by hydraulic fracture stimulation in the Marcellus Shale shows changes in stress state for different zones of failure. During the treatment, shear failure occurs on both the J1 and J2 fracture orientations in response to different maximum stress orientations, indicating localized changes in the orientation during the treatment. Reactivation of a fault near the wellbore is associated with failure mechanisms with a higher volumetric component, indicating possible inflation of faults and fractures by the introduction of the slurry. Quantification of the stress conditions that are associated with inflation could potentially be used to optimize the stimulation by identifying which fractures will preferentially take on slurry volume.

VG Abstract

Microseismicity induced by hydraulic fracture stimulation of a horizontal well was mapped with a near-surface buried array. Distinct linear trends of events were not parallel to the direction of fast shear wave polarization measured in the reservoir with a crossed-dipole anisotropy tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source mechanism analysis supports the interpretation of reactivated existing fractures rather than the formation of hydraulically-induced tensile fractures.

This is a less-technical education topic. It can be condensed to an hour or given as 2 two-hour sessions. It stresses selected controversial aspects of fracking that touch some combination of environment and economics and includes a short video of how fracking is done.

VG Abstract

This lecture will discuss the differences between carbonates and siliciclastics from their chemical composition through their distributions in time and space. Building on these fundamental differences, we will explore the challenges carbonates pose to petroleum geologists in terms of seismic interpretation, reservoir quality prediction, field development, etc. Peppered with humorous personal stories, still raging academic debates, and the heartfelt frustrations of real industry professionals, the aim is to inspire students and young professionals to rise to the occasion and embrace the reservoir rocks that petroleum geologists love to hate.
