Geosteering Services by scope of work

Chinook delivers customizable Geosteering Services and solutions based on specific company needs ranging from look-backs to full-active geosteering.
Setup and deliverables are listed below:

Active Geosteering

24 hours per day active geosteering performed by a rotating team of two geosteering geologists. The geosteering team can be working from Chinook’s Operation Space (hardware and software licenses included in service), from Operator’s premises (hardware and software supplied by Operator) or from field offices (hardware and software leased by Chinook as part of the service). Multiple wells can be steered simultaneously by the same team.

Service includes:

  • Project Set-up (included in service)
  • Solo platform access
  • Geosteering interpretation of the well being drilled (24 hours/day)
    • Cross-section, Distance to markers at last survey point, Apparent dip calculation along the wellbore
    • Look-ahead targets (ahead of the bit): MD, TVD, SS, Inc; fixed targets, corridors, floating targets, or precision steering
  • End-of well report
    • Cross-section, Horizon exports (X-Y-Z), Well statistics (in-zone-out-of-zone, distance to boundaries)
    • Plan view and 3D View in pad context (relative to drilled wells, planned wells, offset wells)

Remote Geosteering Services

In-field Geosteering Services

Nite Geosteering

12 Hours shift geosteering supervision to augment reservoir navigation performed by staff geologists or geosteerers.

Geosteering projects are shared on-line and in real-time with staff geosteering team. Nite Geosteerer works from a dedicated station in Chinook’s Operations Space. Multiple wells can be steered simultaneously.

Project set-up is usually done by staff team, but can be built by Chinook geosteerer as well. Access to shared online platform such as ROGII Solo for Starsteer is preferred and can be arranged by Chinook. Active geosteering is performed by Nite Geosteerer while on shift at 2-4 hours intervals or as needed. Service includes:

  • Project set-up :
  • Solo platform access
  • Geosteering interpretation of the well being drilled (12 hours/day)

    • Cross-section
    • Distance to markers at last survey point
    • Apparent dip calculation along the wellbore
    • Look-ahead targets (ahead of the bit): MD, TVD, SS, Inc

Lite Geosteering

Reduced volume of geosteering interpretations interpretation while drilling, used as a second opinion or guideline for wellsite operations.

Service includes:

  • Typically two updates per day, interpreting position of wellbore and offering long range targets.
  • Project set-up included in service
  • Geosteering interpretation of the well being drilled
    • Cross-section
    • Distance to markers at last survey point
    • Apparent dip calculation along the wellbore
    • Look-ahead targets (ahead of the bit)
  • End-of well report
    • Cross-section
    • Plan view and 3D View in pad context (relative to drilled wells, planned wells, offset wells)
    • Horizon exports (X-Y-Z)
    • Well statistics (in-zone-out-of-zone, distance to boundaries)

Retro-Steering

Look-back geosteering interpretation of wells and pads performed after drilling concluded. Position of wellpath within the target zone is analyzed. No real-time targets are produced.

Service includes:

  • Set up geosteering project
  • Geosteering interpretation for each well
  • Pad statistics and displays

Competitor Analysis

Geosteering interpretation of competitor wells and pads. Visualize where they drilled, well design, targets zones used.

Service includes:

  • Set up geosteering project
  • Geosteering interpretation for each well
  • Pad statistics and displays

Field development

On-demand

Geosteering interpretation deployed temporarily, on short notice.

When needed, Chinook on-call geosteerers can quickly run data through geosteering software and create a punctual interpretation. This approach is especially useful when the location of the wellpath relative to formation markers is not known or when a second opinion is needed.

Geosteering Services by location

Depending on project size and duration, as well as operator preferences, geosteering services can be deployed from operators premises, from Chinook’s Operation Space, from field offices in conjunction with Geological Wellsite Supervision, or in combinations.

Chinook Operations Space
Remote Geosteering from Chinook location

Location: At Chinook’s office
Personnel: 4 geosteering geologists, working 12 hours shifts in 2-weeks-on / 2-weeks-off hitches; Dedicated team is screened by operator and takes part in pre-job meetings
Operation covered: One team can supervise multiple wells drilling concurrently (generally up to four wells)
Logistics:

  • Geosteering done from Chinook offices
  • Software leased by Chinook, billed back to Operator
  • Redundant internet connection provided by Chinook (DSL, Cable and Cellular)
  • Dedicated work station in our operation room
  • Dedicated phone line for 24 hours access
  • Pason/EDR access (supplied by Operator)
