Event description

About this Event

This is a 3-day virtual course scheduled to run from 09:00 am to 05:00 pm US Central Standard Time (CDT/CST) (GMT-5) all three days (4 December - 6 December 2020).

The 900 GBP price includes the ticket for all 3 days.

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 normally schedules a quick technical walkthrough before the course to check bandwidth and Zoom setup and to introduce Miro which will be used as canvas for exercises in groups and collaboration during the lectures.

About the course:

During our virtual course we cover the theory, then apply it to real-life examples. 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 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 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 take decisions.

You have never experienced anything like this before.

The course objective:

The objective of the course is to introduce, understand and apply the concept of geological well placement, provide the knowledge of the processes and techniques that are used to successfully place horizontal and deviated wells using geological and petrophysical data in real time.

This will be achieved by:

  • Learning step by step every aspect of decision-making process that geosteering teams face on a daily basis.
  • 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 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

“If you cannot explain it simply, you don’t understand it well enough.”

At GeoModes, we live by this.

Geosteering is complex enough without speaking about it in a complicated way. That is why we offer our clients additional simple and clear explanations in the form of the book - Horizontal Well Geosteering Guidelines.

In this first-ever comprehensive technical guide, the question “to steer up or to steer down?” is easily answered as the author takes the reader through the geosteering decision-making process step by step. The book focuses on three main areas: planning horizontal wells, geosteering methods; and steering instructions, allowing the next generation of industry talent to learn the unique skill of geosteering horizontal wells in half the time of the traditional learning process.

This geosteering compendium is a unique position because such content has never been published before. It is now available to everyone. Everything you need to know to answer the “steer up or down” question is here.

The book is a perfect tool to get prepared for the 3-day virtual Horizontal drilling and geosteering course and it can be purchased on BLURB and AMAZON.
