    Petrel Well Design

    The Petrel Well Design course is designed specifically to learn the well planning fundamentals and Petrel drilling workflows through four (4) main topics: offset well analysis, well design, well positioning and real-time operations.

    You will be guided through the preparation stage for the data used in well design: this includes the project setup, data import and preparation processes. You will learn how to import well trajectories and targets from third-party applications, such as EDM. You will undertake well design exercises integrating all the elements of the well planning:

    • from making offset well analysis using drilling risks;
    • defining geological targets;
    • building drillable well paths to intercept geological targets;
    • running trajectory uncertainty analysis;
    • creating driller’s targets;
    • performing anti-collision analysis;
    • modifying the planned well path to avoid collision with nearby wells;
    • and finally generating reports and plotting.

    After the planning phase, you will learn how real-time data acquisitions are handled in Petrel.


    This course is available in the following languages: English - Russian

    Day 1

    Day 1: Modules 1, 2, 3 & 4

    • Offset Well Analysis
    • Drilling Structure
    • Geological Target

    Well planners must have high-quality offset data to optimize well designs. When there is no offset data, the well planner must be more conservative in designing wells and include more contingencies. This first part of this session will start by introducing the functionalities available to establish a collaborative environment enabling integration and teamwork throughout the well design process. Then the participants will learn about:

      • importing, creating, visualizing and managing the data from existing offset wells, including drilling events, BHA and risks information;
      • setting up drilling structures and slots which allow well planners to place wellheads accurately and organize wells;
      • creating or importing geological targets which are used in the well planning phase as key points of interest.

    Well plans are the proposed wellbore trajectory for intended drilling and wells in Petrel can contain multiple imported, created, or converted well plans. The Well plan Designer and Well Templates can be used to create multiple versions of plans per well. By comparing different well paths to their original targets, the geologist and driller can select the best well path as the future well to drill. The second part of Day 1 will allow the participants to design and quality check well plans leveraging the various options available in Petrel.

    Day 2

    Day 2: Modules 5, 6, 7 & 8

      • Well Positioning
      • Real-time
      • Plots
      • Relief Well Design and Simulation

      Day 3 session will have three (3) parts.

      Part 1

      In drilling, collision is a familiar problem and, hence, how to detect the collision and modify the well plan effectively are very important in well design. The collision prediction is related to well positioning; whenever a well is surveyed, measurement errors from a variety of sources introduce some degree of uncertainty about the actual position of the borehole. The successful positioning of a well in an area of pre-existing wells requires:

      • Geology information
      • Trajectory uncertainty information
      • Anti-collision scan
      • No-go zone creation

      In the first part of this session, the participants will be guided through the process for understanding trajectory uncertainty, calculating driller’s target, performing anti-collision analysis, generating a no-go zone and adjusting well plans based on anti-collision results and a no-go zone to minimize the risk of collision while maintaining the most practical path to the target.


      Part 2

      The second part of this session will be dedicated to:

      • real-time data streaming in Petrel for quick decision making, risk mitigation, and intervention on a well as it is being drilled;
      • the two (2) major plotting methods used by drillers for well plans: the well plan map view and the well plan vertical view.

      Part 3

      The final part of the course will focus on providing the participants a basic understanding of relief wells and how they are designed and validated in Petrel.

      With more challenging wells being drilled that target highly productive reservoirs, it is becoming a requirement to plan relief wells before drilling operations begin. Should an incident occur, it is critical to know what is required to stop the well, how the well trajectory should be designed to intersect with a blowing well, and what rig storage and pumping capacity is required to stop the blowing well.

      Relief wells are drilled for blowouts as well as to solve complex well control issues that cannot be resolved through surface intervention. And Petrel allows you to create a relief well efficiently from an existing target well, following standard procedures and using well-known constraints for the automated trajectory design. The relief well drilling simulation allows you to use the designed relief well trajectory to run a quick assessment of kill requirements from a dynamic hydraulic perspective.
