Realtime Drilling systems uses - WITSML, WITS & OPC for drilling efficiency, reduce NPT, etc.

WITSML / WITS data has spatial components which is not being utilized for any geospatial

analysis and are restricted within WITSML servers.

Geospatial Platform supports in well planning & execution stages.

An open Information Transfer Standard,Supports drilling workflows. Well, Wellbore, Risk, Formation Markers, Log objects are utilized. Each object has one or more spatial attributes- Lat/ Long, Depth,

Azimuth & Inclination. CoordinatesRefSys & WellCRS objects carries coordinate information.

• Log, Mud Log• Cement Job, Risk• Formation Marker

Each workflow monitors the well using various performance indicators. Realtime drilling workflow outcomes will be represented as non-spatial

attributes of the well. Non-Spatial attributes would be displayed in real-time based on change in

time or depth index.8

Well profile will be rendered with trajectory stations. Current Bit depth will be rendered on the well profile. Movement of bit

depth will be updated based on the realtime status. On the offset profile the formation markers and risk will be rendered.

Risk is tied with formation Markers,depth range and Hole section.Each Risk is characterized by its Types,

Category, Subcategory, Ext. Category,Severity, Probability, Affected Personnel& Mitigation.4-5 offset wells & 100 risks may be

considered during well planning.

Run Spatial Analysis & Density Analysis to identify Risk based on HoleSize and Rig Activity.

Display Risk ,consequence and mitigation steps. Alert users when bit is approaching the risk.

Support both well planning and well execution stages

Offer live map to monitor realtime drilling operations across the globe.

Renders both realtime and future rig acgtivity ot well status.

Not intended to replace any existing industry specific drilling and G&G

apps.

Useful for beginner to expert level personnel.

Enable collaboration between experts.
