Petrel Well Design - RILS (Remote Instructor-Led Series)

This is a Remote Instructor Led Series (RILS) training. The remote classroom delivery is a modality that takes advantage of the instructor led training content, while allowing the same content to be delivered remotely. All training sessions will be delivered online with no face-to-face classroom attendance.


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.


The Petrel Well Design - RILS course will be delivered over a total of sixteen (16) Hours; i.e. in two (2) sessions lasting 5 Hours each, and a third session which will last 6 Hours .

Each participantwill need the following for an optimal experience of the course:

  • Windows-based PC
  • USB headset
  • Internet access
  • Second monitor or tablet for the course manual(s)
  • Webcam


---------------------------------------------------

Note: This course is available in the following languages: English Russian.


Session 1: Modules 1, 2 & 3

(5 hours)

  • Offset Well Analysis
  • Drilling Structure
  • Geological Target


Wellplanners must have high-quality offset data to optimize well designs. Whenthere is no offset data, the well planner must be more conservative indesigning wells and include more contingencies.

This firstsession will start by introducing the functionalities available to establish acollaborative environment enabling integration and teamwork throughout the welldesign process. Then the participants will learn about:

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


Session 2: Modules 4 & 5 (Part 1)

(5 hours)

  • Well Plan Design
  • Well Positioning


Well plans are the proposed wellbore trajectory for intendeddrilling and wells in Petrel can contain multiple imported, created, or convertedwell plans. The Well plan Designer and Well Templates can be used to createmultiple versions of plans per well. By comparing different well paths to theiroriginal targets, the geologist and driller can select the best well path as thefuture well to drill.

During this second session, the participants will learn in-depthhow to design and quality check well plans leveraging the various optionsavailable in Petrel.


Session 3: Modules 5 (Part 2), 6, 7 & 8

(6 hours)

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


This third session will have three (3) parts.

Part 1

In drilling, collision is a familiar problem and, hence, howto detect the collision and modify the well plan effectively are very importantin well design. The collision prediction is related to well positioning;whenever a well is surveyed, measurement errors from a variety of sourcesintroduce 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-collison scan
  • No-go zone creation

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

 

Part 2

The second part of this session will be dedicated to:

  • real-time data streaming in Petrel for quickdecision making, risk mitigation, and intervention on a well as it is beingdrilled;
  • the two (2) major plotting methods used bydrillers for well plans: the well plan map view and the well plan verticalview.


Part 3

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

With more challenging wells being drilled that target highlyproductive reservoirs, it is becoming a requirement to plan relief wells beforedrilling operations begin. Should an incident occur, it is critical to knowwhat is required to stop the well, how the well trajectory should be designedto intersect with a blowing well, and what rig storage and pumping capacity isrequired to stop the blowing well.

Relief wells are drilled for blowouts as well as to solvecomplex well control issues that cannot be resolved through surfaceintervention. And Petrel allows you to create a relief well efficiently from anexisting target well, following standard procedures and using well-knownconstraints for the automated trajectory design. The relief well drillingsimulation allows you to use the designed relief well trajectory to run a quickassessment of kill requirements from a dynamic hydraulic perspective.
