1 STRATEGIES FOR MANAGING LARGE AMOUNTS OF RASTER LOG DATA Brandon Schroeder

2 DATA MANAGEMENT INITIATIVES General Principals Capture and catalog data as it s coming in Provide the G&G users access to the corporate data sources deliver accurate, trusted data to the application projects Maximize Data Asset

3 DATA MANAGEMENT CHALLENGES Increased Data Volumes New methods and data types Public data sources Partner data Increased drilling activity Knowing what s available Confidence in quality of data

4 RASTER LOG CHALLENGES 3 rd Party Data Sources Internal Data Sources (Raster/Digtial) Subscriptions, Contractors, Partners Inefficient Workflows Network Storage G&G Projects Data is delivered directly to the end users. No mechanism for effectively cataloguing what has been delivered Data now resides on local system Network Drive storage challenges Project data stores used as inefficient data management strategies Potential results in ordering the same data Documents Tops

5 LEVERAGING TOOLS TO STORE IN PPDM NeuraDB Loaders Connect to Vendor Data Crawl Network Drives Drop box Functionality Connect to Project Data Scan an d Digitize Capture new data as it comes in Associate log data to existing wells Extract data from SIF files to produce header information Crawl network drives for Raster images Use file names and/or folder structure as metadata to identify Drop box for autoloading log files Extract data from Project data stores with related well header information.

6 DATA MANAGEMENT WORKFLOWS 3 rd Party Data Sources Internal Data Sources NeuraDB Loaders Tops Deviation Production Perforations IP DST (Raster/Digtial) E&P Data Management NeuraDB(PPDM) Production Formation Tops Deviation Surveys Raster / Digital Perforations DSTs Digital Well File Docs Network Storage Accounting Production Drilling Documents Production NeuraDB Users Search Map Export G&G Projects Tops Deviation

7 ADVANTAGES TO STORING WITHIN WELL MASTER Data Integrity De-duplication reduction of required storage Known Source of last updated raster log Single source to store, search and export data Advanced Search Area of Interest, advanced metadata searches Specific Queries (e.g. only new logs loaded this week) Find all logs (digital and raster) by well Identify data as it relates to fields, projects, areas and business entities Efficient Workflows Generate depth calibration files to managed version of the raster log Merge multiple depth registered logs to create a composite log file Digitize raster logs

8 DELIVERING DATA TO APPLICATIONS Export functions DRA & LIC files easily imported into G&G applications Transform calibration information into the target G&G application. Re-pathing location of Raster Log Storage Integration capabilities Partnerships with middleware providers to ensure data can be integrated directly

9 ADDITIONAL ADVANTAGES Project creation Source for establishing project data, which includes the raster logs and well header information Single source for searching for well data Leverage versioning to create a master record from multiple sources. PROJECT CREATION NeuraDB Users Search Map Export Tops Deviation G&G Projects

10 SINGLE SOURCE OF TRUTH Leveraging the version tables in PPDM Create composite record from multiple sources Attribute promotion based on client defined rankings and criteria Composite Source A Source B Source C Source D Creating the Gold Record

11 REFERENCE VALUE MANAGEMENT Defend against poor quality data (or bad data values) Leveraged PPDM to allow organizations to setup aliases and automatically change reference values such as log types, document types, source, operators, etc. upon loading and indexing data. Business rules ensure that future data loads respect the changes in reference values and do not add bad value to the database

12 CONCLUSIONS Raster logs provide unique challenges that can be mitigated by improved workflows All data is captured in a single system (providing confidence to know where to look) Creating single source of truth for well and log data provides confidence in the data Flexible search and delivery capabilities ensure users can easily find and use the data.
