It has been an eventful and productive year for CREWES. 2013 was our 25th anniversary year, and it was punctuated with new field equipment, new spon-sors, and new ideas for CREWES research. We’re getting our next 25 years off to a rousing start! In the summer, CREWES (in collaboration with Carbon Management Canada) drilled two new geophysical observa-tion wells at our Priddis test site, and refurbished the exist-ing well. The main new well is instrumented with 48 3C downhole geophones, and has also had three optical fibres installed. CREWES also de-signed and built a new shear wave thumper, so our field-work infrastructure has jumped ahead this year! With the
wells drilled, we carried out an initial shoot, at the same time doing some dynamite tests in obliquely drilled shot holes, to analyze source elas-tic radiation patterns. Kevin Hall who led the drilling initi-ative, summarizes these activ-ities on page 6. The CREWES student and sponsor population has under-gone its usual dynamic varia-tions too: 7 students graduat-ed in the past half year, and 9 new students have arrived! Profiles of the new students can be found on page 2. Also, two new sponsor members are in the process of joining – we welcome Sinopec and Pemex and look forward to a long and rewarding relationship. Looking ahead, we are in the process of applying for our
next NSERC CRD grant. This grant program, which we can use because of our longstanding industrial spon-sors’ support, has been a mis-sion-critical component of CREWES funding for 20 years. The NSERC site visit is now scheduled for March 24. We are tremendously appreciative of all the sponsor support for hopefully making this application a success! We’ve had a host of big tech-nical successes in our 25th anniversary year. We’re looking forward to seeing you at our booth at this year CSEG convention, where we can show them all off to you! Best Wishes, Kris Innanen Associate Director

Staff Profiles: Kevin Bertram and Malcolm Bertram
Volume 26, Issue 1 Page 5
Kevin Bertram was born New Zealand, and immigrated to Calgary with his family when he was a baby. He grew up listening to tales of seismic field experiments and how to repair broken field equipment from his father, Malcolm Bertram. He received his certification in Electronics from SAIT in 2005 and then started working in the as-sembly of seismic acquisition devices. He moved to repair and then eventually into field service departments where he provided training and repair service to crews in all parts of the world.
Kevin joined CREWES in September 2009. He provides technical support for CREWES both in the office and in the field and can often be found in the recorder during field work.

Left: Malcolm and Kevin Bertram in the mini vibe.
Malcolm Bertram received a BSc in Geology from the University of Auckland, New Zealand in 1971. He then spent some time as a geologist in the Pilbara region of Western Australia before joining Geophysical Services International in Perth. After returning to New Zealand in 1974 he was employed by the University of Auckland as the geophysics technician, where he made the ac-quaintance of Don Lawton who was working on his PhD at the time. He followed Don to Canada in 1980 and became the geo-physics technician for the Department of Geology and Geophysics at the University of Calgary. When the CREWES consortium was formed, he provided the technical and IT support for the project, up until CREWES acquired their own staff.
After retiring from the Department of Geoscience in 2008 he joined CREWES as a researcher specializing in seismic acquisition and field techniques. Malcolm is well known for his field repairs and innovative fixes (fondly called “Bertronics”) and has been invaluable to CREWES during all major field projects for the past 25 years.

New tools to advance acquisition experiments
In 2013 CREWES expanded its inventory of equipment used to perform real world seismic acquisition experiments. These included a new shear wave thumper source and two new test wells installed at the Prid-dis test site south west of Calgary.
THE THUMPER
CREWES designed and built a new shear wave accelerated weight drop seismic source for multicomponent seismic surveys. The source was built around an accelerated weight drop device built by United Ser-vice Alliance Inc. The entire system is mounted on a tandem axle trailer. The source uses an adjustable nitrogen spring to accelerate a hammer towards the ground. This hammer then strikes a clawed foot which has the weight of the trailer on it. The mast on the trailer is pivoted on the clawed foot such that it can be rotated forty five degree towards either side of the trailer. This enables the thumper to generate both P and S waves.
An innovative aspect of the design are extendable legs that stabilize the trailer during source operation to minimize rotation of the trailer when the source fires. A triggering system was designed to enable vertical stacks to be obtained at each source location. The source is set up to be recorded by either the 120 channel Geode system or the 600 channel ARIES recording system owned by the University of Calgary, both operat-ed by CREWES staff.
THE WELLS.
CREWES was able to carry out the installation of two test wells installed at the Priddis test site with the support from Carbon Management Canada (CMC). The test well project originally planned to have three new wells drilled, cased and cemented and the existing well re-drilled to a larger case diameter, cased and ce-mented. A fixed budget was specified, with any cost overruns to be ab-sorbed by first dropping the third planned well, then the re-drilling of the original well.
The drilling, carried out by GroundForce Drilling, for the first well be-gan at the end of September. A 311mm hole was drilled to 31.5m, and a smaller diameter bit was used to core the hole. Coring was carried out to 124m, and the decision was made to drill the larger diameter hole for the casing.

New tools to advance acquisition experiments (continued)
It was also decided that this well would have permanently installed instruments on the outside of the cas-
ing. Twelve downhole geophone cables from Weir-Jones Engineering were used . Each cable has four 3C geophones at 10m spacing except, for the last one which only has one. Since these cables were originally de-signed for a much deeper well, some interleaving of the geophone cables was required to install the geo-phones at 3m spacing without an excess of cable in the bore hole. The geophones were attached to the well casing using Gorilla Tape and zip ties.
Along with the geophones, 400m of stainless steel tubing with one single mode optical fibre and two multi mode fibres were donated by Halliburton (Pinnacle) to be installed along with the geophones. The centre of this cable was bent around a casing-width curve and taped to the outside of the casing at the connection between the float shoe and the bottom-most length of cas-ing. The tubing was then taped to the casing every 3m as it was installed into the well. After the drillers had left Halliburton constructed a wooden frame to anchor the exposed tubing and brought the ends of the tubing into a job box.
The single-mode downhole fibre was spliced to surface fibre, and Halli-burton recorded Vibroseis sweeps and dynamite shots at a 1 m sample inter-val with a distributed acousticsensor (DAS) during the seismic program conducted the week of October 14-18. Following the seismic program, one end of the single-mode fibre was spliced to a short length of patch cable ter-minated with an E2000 PS high power connector.
The same seismic survey used the downhole geophones as receivers. Upon reviewing the data from these geophones it was noted that the uppermost phones did not appear to be well coupled. GroundForce was con-tacted, and they checked both wells with a plumb-bob on the inside of the casing, detecting cement in both
cases. The company offered to drill out the cement inside the casing at their cost, but were turned down on the grounds of probable damage to the casing and instrumentation if this was attempted. GroundForce inserted a tremie pipe in the Well 1 annulus to a depth of 24m, and re-cemented to surface. Well 2 casing was also re-cemented to surface.
CREWES is looking forward to the many experi-ments that can be carried out with these new devices now available.
