1 Schlumberger Public Real-Time Data Link From Desperado to Esperanto Bruce Fogelsong Real-Time Architect - SIS Drilling Real-Time Data Link Project Architect Oct 18, 2007

2 Schlumberger Public The ugly status quo of Real-Time: Desperado Desperado: –A violent or reckless person involved in attempting spectacular feats Real-Time App Programmers have had to be “Desperados” –Writing custom code to access different data sources –“Oh yeah, and can you also make it talk protocol X with System Y?” “Standard Variations” –“I thought you said WITSML was a standard?” The wisdom of the Eagles –And the fences between the application and the RT data are generally topped with razor wire. Desperado, why don’t you come to your senses? You’ve been out riding fences for so long now.

3 Schlumberger Public The beautiful dream: Esperanto In 1887 Ludvic Lazuras Zamehof “jumped the fence” and wrote WITSML –Really? No –But he did create Esperanto A new easy-to-use artificial language that could be employed as a common, 2 nd language, fostering better international communication His language goals: –Common, Easy to use –Reduce communication burdens –Foster international understanding Alternatives to Esperanto –Learn N foreign languages! –Don’t communicate! Which makes me think of WITSML –Has it ushered in World Peace? Not yet But it is Esperanto for Real-Time Data Communication But was the dream fully realized? Enter Real-Time Data Link (RTDL) because: “Knowing the language is not always enough. One also needs a local guide to avoid trouble.” Implementing WITSML Clients can be painful. RTDL “centralizes” the pain, puts it outside your application, and serves as your local WITMSL guide. Real-Time Data Link Makes life easier for both the User and the Programmer

4 Schlumberger Public Where Real-Time Data Link Fits in the Data Landscape The focus of this presentation

5 Schlumberger Public What is Real-Time Data Link? RTDL is a.Net 2.0 software component –A.k.a. DataLink2 It can be bundled with Windows applications –Provides easy access to disparate data sources –Supports both bulk and RT data access It has both an API ….…..…and………..…. a……...……GUI Current commercial version is 3, with v4 in Q4, 2007 Abridged list of client applications: –Perform View, Petrel, RTGS, Stonefish RT, Interactive Petrophysics, DDRT, DDToolBox Real-Time Data Link A friendly buffer between your application and WITSML. Easy on the Programmer

6 Schlumberger Public RTDL Sources of Data Data Types Available with RTDL Log Channels – depth or time indexed Trajectories Image Log Channel Data Risks Tubulars (v4) Real-Time Data Link abstracts the source of the data. Easy on the User

7 Schlumberger Public How do applications Subscribe to data via RTDL? Two Key Concepts 1.Requested Data –Define what data types, indices, data ranges an app needs. –Examples: HKLD, Time Log, Depth Survey Any, Any 2.Available Data The data found that matches the Requested Data Description

8 Schlumberger Public Easy on the Programmer – 4 steps to Real- Time Data Hello RTDL World: Update an XY Plot with Real-Time data from a WITSML Server // 1. Create RTDL Instance IDataLink2 rtdl = DataLink2Factory.CreateInstance(); … private void button1_Click(object sender, EventArgs e) { // 2. Create Requested Data Description rtdl.CreateRequestedData(EDataType.Log, EIndexType.Time); // 3. Define where to receive data rtdl.AssignDelegate(new EventHandler (this.rtdl_DataDispatch)); // 4. Initialize Component and Show User Interface rtdl.Initialize(); } … // Respond to new Log Data events and update XY Plot in Real-Time private void rtdl_DataDispatch (object sender, DataDispatchEventArgs e) { foreach (ILogData logData in e.Data) { this.realTimeDataChart1.AddData(logData.Value.Value); }

9 Schlumberger Public Conclusions Real-Time Data Link: –Is also known as DataLink2 –Is used in 7 SLB RT Applications, with more under development –“Centralizes” the WITSML pain, outside of your application –Is able to connect to multiple WITSML, and other, data sources –Provides an API for a program to subscribe for Requested Data Descriptions, either explicit or implicit –Queries the data source for any Available Data Descriptions which match –Maps explicit Requested Data Descriptions to Available Data –Provides a GUI for custom mapping & additional data selection –When data is received it’s asynchronously sent to the application –Has an “SDK” with a Test Work Bench that is useful for testing and troubleshooting –Makes life easy for both the User and the Programmer –Please provide us with your feedback: –Questions?
