This is a 3-day virtual course scheduled to run from 09:00 am to 05:30 pm CET (GMT+2) on all three days.

The price includes 1 person access for 3 days. Once the course is purchased, a confirmation email with all the course details will be sent (within 24 hrs). If there are no seats left, you will not be able to book the course. 

The virtual face-to-face class is highly interactive and discussion-based so a stable internet connection and a laptop or computer with a microphone and webcam are required.

The instructor will schedule a quick technical walkthrough before the course to check bandwidth and camera setup and to introduce Miro which will be used as canvas for exercises in groups and collaboration during the lectures. You will be able to select a convenient for you time of the technical walkthrough but please remember that the attendance of this short 15-min check up meeting is mandatory. 

 

We have created an “on-the-job” environment that brings the theory to life.

Through our carefully designed course, we offer close to reality simulation of everyday decisions a geosteerer must face at work. You will practice the process of geosteering a well that is drilled at a speed of 250 feet per hour. You will be exposed to time pressure, presented with unclear real-time data and challenged by the ambiguity of the steering direction. You will experience the feeling of being a geosteerer.

Our course, packed with all-possible geosteering challenges, explains step by step the complexities of the geosteering decision-making process. You will not simply participate in this course, but you will be part of it and shape its content with others. You will speak, discuss, observe and make decisions. You have never experienced anything like this before.

The objective of the course is to introduce, understand and apply the concept of geological well placement. You will also be  provided with  the processes and techniques that are used to successfully place horizontal and deviated wells using real-time geological and petrophysical data.

 

This will be achieved by:

  • Learning step by step every aspect of the decision-making process that geosteering teams face on a daily basis.
  • The practice of various geosteering techniques and rules involved in directional drilling, calculations, and formation evaluation while drilling.
  • Applying Geosteer Well On Paper (GWOP) concept, a new step in the well delivery process that involves all steering activity’s due diligence.

 

The course is designed for:

  • Geosteerers, Operations Geologists, Wellsite Geologists, Operations Petrophysicist, Operations Team Leads
  • Drilling Engineers, Directional Drillers, MWD and LWD specialists, Mudloggers and Data Engineers
  • Students of Petroleum Engineering, Drilling and Geology who aspires to work in the Oil & Gas upstream industry
  • Anyone who aspires to become a member of an operational team that drills deviated and horizontal wells
  • Anyone who would like to understand or improve the understanding of the geosteering science

Day 1

Module 1. Geological Well Placement and Reservoir Geology

The first half of the day will focus on basic concepts and application of well placement. Participants will be presented with reservoir geology and structural features review that imply the need for horizontal well placement. The day will continue with an evaluation of the steering systems and their geometrical features that influence the steering. The main concepts of how wells are geosteered will also be presented. At the end of the day participants will learn about real time versus memory mode data transfers and communication ways with the BHA tool downhole.

  • Basic concepts and application
  • Essential elements of reservoir geology
  • Structural features
  • Steering systems
  • BHA steering tendencies
  • BHA orientation and tool face
  • Real-time data transfer

 

Module 2. MWD directional drilling, surveys and position uncertainties

Module two will start with discussion about directional drilling and MWD surveys. Participants will learn about surveys calculation methods and the technologies and techniques involved in controlling the location of a wellbore. Survey spacing and static and instantaneous surveys will be presented. The day will continue with a discussion about the concept of ellipsoid of uncertainty. Collision avoidance and collision risk visualization will also be covered.  Survey uncertainties and structural uncertainty will wrap up the day.

  • MWD directional surveys
  • Survey calculation methods
  • Survey spacing
  • Static and instantaneous surveys
  • Surveying instruments
  • The ellipsoid of uncertainty
  • Collision avoidance
  • Structural uncertainty

 

Day 2

Module 3. Well trajectory

Creating geological and drilling targets will be the focus of the first part of the day. Participants will also learn the process of planning an optimal well trajectory with respect to DLS limitations, build rates and BHA tool building capabilities. These topics will be followed by covering the topics of steering modes and rates. Sidetracks and avoiding various obstacles while steering will also be discussed. Towards the end of the day practical examples will be given to review the geosteering limitations imposed by certain well trajectories.

  • Geological and drilling targets
  • Dogleg severity DLS limitations
  • Build rate
  • BHA tool building capabilities
  • Steering modes and steering ratios
  • Well trajectory planning
  • Sidetracks and obstacles avoidance trajectories
  • Practical examples of geosteering limitations imposed by different trajectory type

 

Module 4. Application of LWD measurements for geosteering.

In the fourth module LWD geosteering solutions will be evaluated with azimuthal borehole images for reactive and remote boundary detection for proactive geosteering techniques. Participants will learn how to interpret the image patterns and what additional information they provide. Some case studies illustrating the use of the three cross section displays where distortion and projection of the well trajectories will also be discussed. The day will end with the overview of the available LWD technologies with a focus on choosing the right LWD tools for fulfilling various well objectives.

  • Azimuthal borehole images
  • Image patterns and their interpretation
  • Deep directional electromagnetic measurements (remote boundary detection)
  • Proactive and reactive geosteering
  • Cross-sections displays (distortions and projections)
  • Overview of available LWD technologies

 

Day 3

Module 5. Geosteering Methods

On the last day, practical geosteering principles will be discussed. Examples of how to incorporate real-time dip analysis, bed dip and bed thickness calculations into well placement will be given. Attendees will also get an introduction to well landing strategies and will be familiarized with the true stratigraphic thickness geosteering method. Horizontal trajectory management will be discussed during the second half of the day. Critical target change techniques including various drop rates will also be covered.

  • Geosteering principles
  • Bed dip, bed thickness and incident angle calculations
  • True dip versus apparent dip measurements and usage
  • Well landing strategy
  • Geosteering using true stratigraphic thickness
  • Drop rate and inclination changes
  • Horizontal trajectory management
  • Target change techniques

 

Module 6. Geosteering simulation

The last module of the course will be a “real life” well placement experience where participants will be able to “geosteer” a well and test their learnings from the course by answering the most important question of geosteering: to steer up or steer down?

  • Geosteering simulation – team exercise
