Expedio Top Tip – Code Compliance

Code Compliance

Expedio’s Top Tip for May keeping Code Compliance:

Data Mining Code Compliance

Having inconsistent logging codes within a data set will cause major issues when modelling the data. “how do I use this – I can’t model my geology, how do I put this on a section?”  This can be caused by a field geologists creating there own codes in the field “Im not sure what this is, ill just use ???”

The old data management proverb of “S*** in S*** out” comes to mind.

Enforcing company codes is important, consistency in logging is the key. Having a standard set of codes allows data collected to be consistent from geologist to geologist, Field assistant to Field assistant.

Having a field logging tool that has built in checks for valid numeric ranges and valid logging codes like OCRIS Mobile is essential.

Having a process for adding new codes within your company will kept consistency when new codes are required.

Expedio Top Tip – Azimuths and Magnetic Drift

Azimuths and Magnetic Drift

Expedio’s Top Tip for April understanding Azimuths and Magnetic Drift:

DataOcean

Managing azimuths and magnetic drift is very important in maintaining the integrity of your downhole survey data.

Steps in managing azimuths and magnetic drift correctly:

  • Correctly reference azimuths recorded – Is the reading measured in True north, Magnetic north or Grid north. Incorrectly collecting and storing this data will have a massive effects on the quality of the data set.
  • Know the magnetic north to grid north conversion – Magnetic declination tells you the direction of magnetic north, measured from true north, and convergence tells you the direction of grid north, measured from true north. For example countries such as Brazil  have a 23 degree swing between national grid north and magnetic north. Get this wrong and you will miss your target.
  • Be aware of magnetic drift –  Variations in the Earth’s outer core results in changes to the magnetic field and hence the position of the magnetic north and south poles over time.

 

OCRIS Mobile 3.1.8 Release

OCRIS Mobile 3.1.8 releaseOCRIS mobile

OCRIS Mobile 3.1.8 release is here, providing great new user functionality and improved development to the database engine;

  • The addition of a Site list filter in the selection pane. This allows the user the ability to filter when Site lists become too large.

site list filter

  • Updated the application status text, so that users can immediately see which logger is active.
  • Updated the underlying SQLite engine, this will increase the performance of the underlying database engine by at least 60%.
  • Minor bug fixes.

Expedio Top Tip – Data Handling

Data Handling

Expedio Top Tip for February better Data Handling:

Data Handling

Poor Data Handling procedures can lead to loss of data, money and time. This can put a resource project under huge risk of failure. Companies are happy to spend millions of dollars on drilling and lab test work, but lack when it comes to storing the data it returns.

Data Handling problems can be attributed to these main factors;

  • Break down in data flow procedures;
    • loading the same data files several times
    • field collected data and lab results not making it back to the main office and the master data set
  • Non centralised data;
    • multiple copies of the data/database, users and managers working on separate copies of the data. Who has the most recent and up to date version?
  • Data being stored on an unsecure/non backed up system;
    • what would happen if the computer/server dies, do you lose millions of dollars worth of data

Kambalda Geology Symposium Wrapup

Kambalda Geology Symposium held on 21 October 2015 was a great success with around 70 geologists from the surrounding mines and exploration projects attending. It was the first time this event has been held since 2008 and the first hosted at the fantastic facilities on offer at the Kambalda Recreation Centre.

Many speakers were presenting for the first time and all were impressive with a wide variety of topics from local mine geology targeting Ni Sulphides to the latest technology in down hole optical viewing tools, geo-metallurgy and best practise data management principles.

It was very encouraging to meet with so many young people who appreciated the event and the opportunity to meet geologists from the surrounding projects, and of course to enjoy a drink together afterwards.

Expedio would like to thank all attendees and the co-sponsors Cube Consulting and BMGS for their efforts in making the day enjoyable and productive for all.  We hope to see you all again next year
