Shell Exploration & Production Geographic Overview

Shell Exploration & Production The Problem (Overview):  No mandated standard for storing hydrology Well header information  No clear method for marking hydrology wells in the field  No established approach for collection and storage of hydrology sampling event results  No Field based GIS tools

Shell Exploration & Production The Problem (In depth):  No mandated standard for storing hydrology well header information  Hydrology program began as a small R&D effort 20 years ago  Well data was kept in Excel spreadsheets or in peoples heads  No complete record of drilling results  Planned vs Actual drilled  Recompletion info convoluted  Naming conventions non standardized  Survey information not comprehensive  What, where?

Shell Exploration & Production The Problem (In depth):  No clear method for marking wells in the field  Wells were identified in field in different ways, many not identified at all  Evolved into a large number of wells (500-600)  Names changed  Initial attempts to mark wells left much to be desired  Location and Survey info was confusing, not complete

Shell Exploration & Production The Problem (In depth):  No established approach for collection and storage of hydrology sampling event results  Field Data was logged in a Note Book, no digital entry mechanism  Transcription errors occurred  400,000 analytical results housed in disparate locations  Life cycle for data to end consumers was long and siloed  Critical data was housed with consultants  No common platform for storage and dissemination of hydrology data

Shell Exploration & Production The Problem (In depth):  No Field based GIS tools  Hard copy maps were ineffective do to dynamic data environment and amount of data  Needed a digital solution in the field to leverage in house GIS datasets  Wells, Aerials, Lease and Property Boundaries, Federal Land, Resource Info  Aerial, Elevation and Topo data critical  GPS Navigation was a value add

Shell Exploration & Production These Problems resulted in:  Confusion on validity of data  Data Analysis Latency  Over dependency on consultants  Disconnect between back office and field crews  Distrust of data by our end consumers

Shell Exploration & Production

Shell Exploration & Production The Solution (Overview): Well Identification Program (WIP) and Environmental Management Implementation  QA / QC all existing wells  Migrate well header info into OpenWorks  Migrate Environmental Sampling Data into EQuIS  Tag wells in the field with standardized methodology  Develop a field GIS platform to disseminate geographic data

Well Identification Program Objective: To have a system that will help with well and subsequent data identification, and reduce in over-all project costs. Ruggedized Field Laptop Shell Exploration & Production Current Well ID Program: Not clearly defined and confusing; not cost • GPS / GIS Integration effective. • Field Interface for Integrated • EQuIS Sampling wireless GPS Proposed Well ID Program: Physical tagging of wells with a 2D Bar • GIS / GPS Code with relevant information. Navigation • OpenWorks Well DB Benefits of 2D Bar Code System:  Reduction in human effort, and data recording duplication  Elimination of well ID confusion  Aid in data QC and input of data into main databases  Well ID, location, and sample ID errors eliminated EQuIS  In-field managers can track progress on each well Sampling Form  Allow independent field personnel to track latest information at the well site  History is available at each well for all borehole life-cycle activities  Minimizes chance of old data being used  Data latency is significantly reduced  Errors can be quickly corrected  New information can be quickly reported in a hard-copy computer readable format  Barcodes can be quickly replaced if damaged  Bar codes are secure and keep data classified, and are easily combined with encryption and limited user operation procedures. Wireless Bar Code • Well Name Reader • API, UWI • Reads Data from well bar • Total Depth code and reports to field • Drill Date • Comp Date Laptop • LL • Contact • Use/Program • etc The data capacity of a 2-D bar code is up to 3 K Bytes of data. This should be sufficient for the most of the information required including the elevation, coordinates, well construction information including location of the screen and pump, and any other information associated with the well.
