Wellstorm Development Connecting Real Time Data to Everything Hugh Winkler May 11, 2006

Wellstorm’s Business Founded 2004 Broadening the base of real time data suppliers and consumers: “WITSML Everywhere” Enabling data suppliers with WITSML server technology Exposing RT data to web and WITSML clients

Target Audience You need to supply WITSML services to your customers, or you’re an operator with internal real time systems You have a business requirement to retain control over the data you acquire or aggregate –e.g. you distribute data to customers over internet –e.g. you have an application-specific repository You intend to focus your resources on enhancing the value you already give your customers –…not on reinventing the plumbing of getting the data from A to B

Our Status Integrated with M/D Totco RigSense Shipped first integrated systems this year; on track for several dozen by year end Seeking other integration partners

Integrating with Wellstorm We help company build export adapter –Translate internal format to WITSML –Store in Wellstorm repository e.g. log data –Reflect to subscribers Can be a two-way adapter –accept WITSML info –fire update events to host system –Example: send control data back to driller

The Process Two weeks of analysis, typical Four weeks integration, typical Two weeks interface QA, stress testing Validating the correct semantic mapping: variable

Connecting Your customers will be able to connect to their data three ways: –WITSML clients: purpose built applications like GEO, DrillWorks that speak WITSML API –Web clients a browser, maybe a little script feed readers, for updates (v 2) –Real time clients: desktop applications that subscribe to Wellstorm supplies “Click Once” rich client (v 2) We can help you enhance your existing rich RT client or web client software to use these data access practices

WITSML Clients Works with standard WITSML clients software Several companies test client compatibility against our v1 and v2 servers every day Wellstorm supports all WITSML objects; suitable for any application domain

Web Client: Browser Just use a web browser to review repository It’s easy to build a custom web user interface, because all Wellstorm objects have URLs. Note to Nerds: This is an ajax webapp, meaning if you look at the javascript you’ll see how to construct your own rich client application by navigating Wellstorm’s URLs (“lightweight witsml”)

Web Client: Feed Web feeds: a special xml format that feed readers understand (RSS, Atom) Windows Vista and IE7 have built in support for feeds Manageable way to monitor changes over dozens of wells, hundreds of objects

Realtime Client: Solving the Publish Problem Publish interface good for server to server communication but usually can’t push to the desktop Most offices do permit instant messaging, because the connection always is requested by the client Solution: Push objects over instant messaging protocol (RFC 3290) –Secure –More efficient –Actually works We supply this generic client, but you can easily adapt your own RT client software to read this messaging stream

Vision Thing Break your data out of application silos. This means anywhere an application is sitting on a pile of data in proprietary format, expose it in standard formats like WITSML. The data have more value to you when all applications can use it. Metcalfe’s Law: The value of the network increases as the square of the number of nodes. Enable your data to participate in the Web – the most valuable network there is. It can then be used in ways you never anticipated.
