Mechanical Assemblers

Mechanical Assemblers


Nanometrics is looking for contract Mechanical Assemblers to join our production team in Kanata. Responsibilities include the assembly of products using bolts, screws, clips, soldering tools, and assorted fasteners. The Assembler will be responsible for the efficient production of products according to established procedures, following all safety protocols and workplace policies.

"Monitoring in a Western Canadian Shale Play With a Sparse Surface Network: Moment Tensor Analysis Implications,"
Kit Chambers, Senior Geophysicist

Ballroom E during the Induced Seismicity Special Session 
 
Abstract is as follows:
We present results from monitoring the stimulation of 4 wells using a sparse surface network of three-component instruments in a the western Canadian Montney formation. Focusing on the results from moment tensor inversion, we interpret this data set in the context of hydraulic fracture seismicity. During the treatment a total of 7237 events were identified based on P and S arrivals of which full moment tensors were computed for 1960 sources. The temporal and spatial distribution of the events along with their B-value is consistent with hydraulic-fracturing related rather than induced seismicity. The events partition into two groups separated by an aseismic gap. The largest group consists of events occurring near the wellbore, whilst the second group occurs to the north east. Throughout the entire data set we observe similar trends in terms of; event timing, relationship to stages, waveform characteristics and orientations, for both groups of events, which in turn is suggestive of a common causative mechanism for both groups.
 
The decomposition of computed mechanisms suggests that the sources are pure double-couple failures and that observed non-double couple components can be attributed to the influence of noise in the inversion process. The mechanisms are primarily dip-slip/horizontal-slip (DSHS) style sources with a consistent polarity, however, there are notable exceptions where the mechanism polarity is reversed. The existence of mechanism polarity reversals is shown to be robust through the analysis of station gathers. Whilst the observation of polarity reversals excludes a common interpretation for microseismic events, that they are consequent of a pre-existing stress field and their movement is triggered through the reduction of normal stress on a discontinuity. Instead our results are consistent with the source mechanisms being related to the stress field associated with the hydraulic fracture. As the hydraulic fracture grows it alters the stress state in the surrounding rocks, and as such creates favorable conditions for slip on weakness planes (such as bedding planes or joint surfaces) which would otherwise be stable. Our observations illuminate several aspects for this style of faulting. In particular, the separation of event groups could be due to fluid transfer along conduits where there is no seismic deformation, and the distribution of mechanism polarities may be related to the interaction of the local fracture and a regional stress field.

Nanometrics actively contributing to data format discussions

The Data Format working group of the International Federation of Digital Seismograph Networks (FDSN) is holding a workshop, focused on the evolution of miniSEED, on March 22 and 23 in Utrecht, Netherlands. Nanometrics will be represented by David Easton, Senior Manager, Software Development, who has been an active member of the working group for the last year.

Nanometrics prefers contributing to the evolution of data storage and streaming formats in a user community-based approach, rather than attempting to drive proprietary implementations. Our participation also allows us to better understand user needs both from the perspective of the producers of data as well as the data center, to ensure our instrument and data center software is designed for maximum interoperability, efficiency and usability.
