Seismic Imaging in 2D, Reflection & Refraction


Shallow 2D Seismic Reflection Profile,
Bison Galileo Seismic Recording System,
with Software Roll Box.  Most Accurate Reflections Ever Seen.  Correlates to 2D Resistivity Profile Very Accurately. !!!.

The Reflection Seismic Line to the left,  was shot in May of 1995.  All by myself.  One man crew.      It is a 2D reflection section with some 250 records.  It was shot using a Bison 24 channel Galileo (20/20 system) seismograph using a "software seismic roll box".   I collected the data over a 2 hour period in the field and processed the data in about 6 to 8 hours using both WinSeis(KGS) and also Seistrix III (from Interpex).  The reflection between 4 and 10 ms is "the shallowest reflections" observed even by today's standards!    I am not sure if anyone has ever been or will in the future be able to shoot such a shallow reflection with a 24 channel Seismograph.     I also ran a resistivity survey over this same site and collected more data in about 3 hours time.   Please be sure to view this case study under Resistivity Applications within this webste!

 This is the same data set as above displayed with more traces per inch.  You can also see this feature on the Resistivity Profile "St Thomas University",St Paul, MN.  Please note that the brown highlighed Reflector that starts at approximately 60 MS is the St. Peter SandStone!   The Dakota Limestone overlays this huge tremendous body of ocean white beach sandstone,  with at least three distictive Shale Layers,   which really cannot be seen on the above 2D Seismic Section Profile!    They can although,  be seen on the Resistivity Profile entited "St Thomas University"  and is seen under "Resistivity Examples" in this Web Site.

Fractured Bedrock in Northern Spain.  In Apple and Wine Country.  The National Spanish Transportaion Board was building an new tunnel and wanted to see what a shallow bedrock profile of the region would look like.  IGT GS,  Espaina  was the contractor.  From what I knew the profile to the left had very similar structure to the resistivity profile done intial by IGT for the National Spainish Transportation Board.  The above data was collected with a Bison 24 channel 24 bit seismograph.  It used one of the first Windows Graphical User Interface System operations software.  The data for this survey was collected in Sept of 1996.





 


MRSAPS Refraction P and S wave.
Shallow 2D Seismic Refraction Profile  MRSAPS  SOFTWARE  26 Shot Points. !!
Bison 9000A Seismic Recording System .   At the Same Site in St. Paul Above (St. Thomas University along Mississippi River Road).   Everything Correlates !!  The profile to the left was collected by a Bison 9000A system.   26 shot points were used and the data was collected over a few hours.   Much More than the older Five shots that are limited by the old outdated softwares.   26 shot points  were analyzed as shown in the profile by the MRSAPS software which is the "State of the ART" today.  Shotpoints were offend and at every geophone station.      The seismic data from these 26 shots was then analysed with the MRSAPS computer software,  to make the profile to the left.   This is known as Seismic Refraction Analysis,  for subsurface Bedrock Imaging.  This new and outstanding software will handle both P and S wave refractions and can be shown with both the Results of both P and S wave data profiles combined and inverted together ... or shown individually.  NO ONE ELSE IN THE WORLD HAS THIS SOFTWARE.   IT CAN BE USED FOR BOTH DEEP APPLICATIONS OR SHALLOW. 








OutStanding BWS #1 Seismic Reflection Data Processor !

OUTSTANDING 2D SEISMIC DATA PROCESSOR !!   Bret W. Smith,  Geophysicist.
Look at this 2D line.   NO ONE ELSE could show the real geological structures NO ONE.   I can not tell you exactly where the seismic data for this line was collected,  but I can tell you that it shows a full Silurian Reef ! !    Can you see it.  ??  It was collected in SouthEastern Indiana.   It's exact location is a secret.   The data was collected in 2004.   It was processed by several companies..all of whom could not show "The Client", what can clearly  CLEARLY BE SEEN HERE    The Silurian Reef is about 500 feet high and is at a depth of 2,984 feet.    They want to try to use MRSAPS to find if it is full of OIL and GAS before the Drill !  Good Idea ! ?  The Line is shown from West to East.    Again.  ONLY BRET W SMITH,  was able to show this to the client.  !!    WOW !!   From the Surface to great depth.   I did a small project for them.  They were very very unhappy with all the people who processed their data.  Very very few people know how to process seismic reflection data.   VERY FEW.   This line is a tremedous example of my Skill Set !! 





Seismic See Application for Above Line !!!



































<>OUTSTANDING 2D SEISMIC DATA PROCESSOR !!   Bret W. Smith,  Geophysicist.
This is the same line with an application in Seismic SEE. !    This line is a tremedous example of my Skill Set !!   No one  Else   NO  one can do this !


<>OUTSTANDING 2D SEISMIC DATA PROCESSOR !!   Bret W. Smith,  Geophysicist.
The two lines below are from Western Australia.   I WAS NOT PAID IN FULL AND HAD TO TRY TO TAKE THE CUSTOMER I DID THIS FOR TO COURT IN AUSTRALIA !!      HE NEVER PAID ME.   THE WORK I DID WAS  "OUTSTANDING"   NO ONE    N O   O N E  Else could show what I did especially considering it was with an ISEIS system.   Not quite even 18 bits of Resolution( a really crappy system in my view). 

Line 5  Shot points every 5 meters. 5 meter stations. 
Line 1  Shot Point every 10 meters,  5 meter stations. 

Total Shot Points  1282 shot points !!  Total  It took about 300 hours to do these two lines.  I got them to him (he was in a big hurry) in only about two months.  The reprocessor took two years .    I WAS NEVER PAID IN FULL !! ??
Dont ever expect me to do business with anyone there again. !!

They used 10 Hrtz Geophones.  This line was 3,135 meters roughly 3 kilometers.   Wow.   Look at the Detail.   He told me (the customer) that he had to have someone else process the data becuase he could not trust my work.
I dont believe him...but the Judge did. ???    "Awful "  He should be sued.   ...Again.   YOU HAVE A LOOK  

LINE 5   West to East over 3km Long. !!   I should have been Paid at least $1000 dollars per Km.   !!  NO ONE NOT ANYONE IN THE WORLD COULD HAVE SHOWED HIM THIS.  !  HE SAID IT WAS RE-PROCESSED...BUT I DOUBT IT.   I NEVER SAW ANY OF THE REPROCESSED DATA. ???

Look at this outstanding line from Western Australia.  !!!   

Line 5  West to East:
Wow Can you see the Pinicle REEFS !!!



Line 5  West to East with Seismic SEE ! :
Line 5 with Seismic See Wow He Never Paid me. !!

This was the second line.   Look At it    the guy used a 24 channel ISEIS.   Three of them linked together.  The data was NOT easy to process.
 NOT to uncommon in this industry.   NO wonder now no one ever finds anything,  and drilling is highly inaccurate.   Look at the Pinicle Reefs.  These are quite well known in Australia.   They are overlain via a UnConformal Boundry.   Wow.

Line 1  West to East :
Look at this oustanding Line with Pinicles !!




Line 1  West to East SEISMIC SEE :
Wow OUTSTANDING !!!
