These data are part of a preliminary report based on the 22-day, two-phase, 2004 Bristol Bay-Alaska Peninsula field program. The program's first phase focused on source rock potential of the Mesozoic section, and the second phase focused on reservoir potential and stratigraphic architecture of Tertiary rocks. Data included here are rock sample details, field sample locations, total organic carbon measurements, and porosity and permeability analysis results.
This map service is an information surface which displays whether a soil map unit has no hydric components, some hydric components, or if all the components in a soil map unit are hydric. Each soil map unit polygon falls into one of the following classes according to NRCS: All hydric, Partially hydric, Not hydric, and Unknown. Esri is providing NRCS SSURGO content here without modification except for some cartography and publishing necessary to facilitate esri user access to these data. Of course, esri will continue to update this information as new editions of the SSURGO dataset are published by NRCS. This map service is a representation of the NRCS SSURGO data table MUAGGATT, field HYDCLPRS. The map service...

Unconventional geomechanical testing on coal for coalbed reservoir well design: The Alberta foothills and plains
One unconfined compressive strength (UCS) test and four high-pressure triaxial stress tests were conducted on coal cores in order to best emulate the key issues regarding horizontal wellbore stability, coal strength, permeability change, and coal fines generation during the life cycle of a coalbed methane reservoir. The four non-trivial stress paths were: Loading Compression (LC), where the axial stress is increased while the confining stress is held constant; Loading Extension (LE), where the axial stress is held constant while the confining stress is increased; Unloading Compression (ULC), in which the axial stress is held constant while the confining stress is decreased; and Unloading Extension (ULE), during...
Permeability–porosity relationships for sediments from the northern Barbados, Costa Rica, Nankai, and Peru subduction zones were examined based on sediment type, grain size distribution, and general mechanical and chemical compaction history. Greater correlation was observed between permeability and porosity in siliciclastic sediments, diatom oozes, and nannofossil chalks than in nannofossil oozes. For siliciclastic sediments, grouping of sediments by percentage of clay-sized material yields relationships that are generally consistent with results from other marine settings and suggests decreasing permeability as percentage of clay-sized material increases. Correction of measured porosities for smectite content...
