Remote geosteering provides consistent supervision more effectively and safely than conventional methods. It allows for 24/7 supervision from offsite locations to make real-time decisions. This improves safety, reduces costs, enhances data flow and communication. Remote geosteering is used for horizontal wells drilled close to reservoir contacts or zones, nighttime supervision, and combining multiple objectives. It involves continuous monitoring, assessing stratigraphic location, optimizing well placement, providing timeline estimates and reports. This standardized approach improves knowledge sharing and reduces costs through centralized resources and reporting.

2. Objective:
To provide consistent, high quality
supervision, in a more effective, efficient
and safer manner than the conventional
approach

3. Remote Geosteering - WHY
- Safety
- Costs
- Data Flow
- Communication
- Real Time Decision Making
- 24/7 Supervision

4. Remote Geosteering - Where
• Horizontal wells with no need for real-time sample
description. (Steering based on LWD/MWD data and drilling
parameters)
• Drilling close to the roof of the reservoir
• Night supervision for one man Hz jobs
• Follow optimum reservoir zones
• Drilling a set distance above the water contact
• Avoid unproductive zones in the reservoir
• Optimal wellpath placement
• Combining two or several of these objectives in one well

11. Monitor current rig operations, paying particular
attention to nature of bottom hole assembly in the
hole (slick, stiff, pendulum, directional, etc.).
Although this is a drilling matter, the remote
geologist must understand all operations, and
recognize any deviations from the drilling program.
If any deviations are observed, Client’s personnel
are notified as per protocol.

13. Directional Drilling Supervision
Synergetic communication
Collision Avoidance
Plot wellpath into Petrel, and proactively evaluate
wellpath position in relation to existing and planned
wellbores (provides an additional line of defense in
the avoidance wellbore collisions)
EnCana Corporation

14. Additional Benefits
 Knowledge and resources shared in all compartments.
 Standardized internal and government reporting.
 Detailed daily reports, to be distributed within the company and to
partners as needed. Everything stored on client’s dedicated data base,
using consistent file naming protocol.
 Further reduction in cost is realized by reducing the required number
of accommodations, Pason terminals and trailer transportation costs
on the lease.
