Why do we Need a Standard, or What is Wrong Today?

• Microseismic Events– In the majority of cases the Events are

transmitted via column formatted ASCII or Excel (including .csv) files

Dates and Times

• Is Date and Time relative?– What is it relative to?– What are the Units

• Or is Data and Time Absolute?– Do we know the time-zone?– Are the date and time defined in the

same columns or different columns?– What format are the data and time in?

Event Locations

• Are Locations Relative?– Are they with respect to the treatment or

observation well?– Are they in True North or Grid North!!!– What are the Units

• Or are Locations Absolute– What Coordinate Reference System (CRS)

are they defined in?– Do they use the CRS units or something

else• Seen UTM CRS with Feet measurements

Event Vertical Locations

• Are they TVD from Treatment Well?• Or are they TVD from Observation Well?• Or are they Elevation above MSL?

– But what is MSL?• Or are they TVDSS?

– Positive down or up?• Or are they Elevation above a given Datum?

Who is the Biggest Loser?

• The Client• Time required to load the data

– That is if the know all the missing information• Date/Time information can generally be implied• True North/Grid North can not• Units of measure must be known• End result – The can make wrong assumptions –

which can lead to high cost mistakes!

How is it Fixed?

• Build a Standard

•We all Adhere to it

Data exchange between participants

• What do we see?– Data are frequently exchanged across company

boundaries– Data exchange can be real-time or non real-time– Data exchange happens regularly, frequently,

and with absolute necessity– Microseismic trace data accounts for just a few of

these exchanges – Seismic trace-data formats are not suited to

many of these non-seismic data exchanges

What do we need?

• A standard data format for transmitting these data– On disk (probably XML)– Between computers via a network link in real

time (possibly using SOAP or JSON over an internet link)

• Implementation by microseismic providers, consumers, software and hardware manufacturers

• An effort that tries to build on existing standards, when possible.

• Participation, support and commitment by operators, regulators, service companies, and academia

The next steps

Creation of a committee. It should include• Microseismic service providers

(acquisition, processing, consulting)• Oil and gas operators who utilize

microseismic services • Software and hardware manufacturers

who work with microseismic data• Industrial users for non-oil and gas applications• Academic or regulatory bodies that research or

utilize microseismic dataThe committee will work openly and inclusively to accept input from all stakeholders.

Formation of the committee

• Send your nominations to ALL THREE email addresses below. Nominees should be members of the Energistics consortium.

• Henry Bland henry.bland@pinntech.com• Julie Shemeta julie@meqgeo.com• Jana Schey jana.schey@energistics.org

• Nominees will be notified, and asked if they want their name to stand. Nominees from the same company will be asked to consolidate participation to a singe representative. If the committee exceeds 15 people, a vote by nominees shall determine the makeup of the committee.

Committee tasks

• Elect a chair set dates for future meetings• Consult with the special interest group members

(both on and off the committee) to maximize the chance of acceptance of the standard.

• Work directly, or through subcommittees, and with Energistics staff to complete and publish the standard.

Summary

• Inaugural workshop meeting was an excellent first step

• Our industry urgently needs a data exchange standard

• We need to form a Microseismic Committee to direct the development of a standard

• Email your committee nominations by March 26th, 2012

• Spread the word about the work being performed by this group.

• Show this presentation to colleagues within your company
