Course Information

The course will shortly (0.5 days) outline the mechanics of drilling, so that participants gain a general knowledge on drilling rigs, on how a well is drilled and the main challenges of drilling a well.

The participants will then be introduced (0.5 days) to the process of designing a well, with a good overview of all those design items that are defined based on the outputs of the subsurface team’s work (such as directional path, directional tools, drilling fluid selection and characteristics, completion requirements, casing setting points, casing characteristics).

In the following two days of the course, the participants will “become” well engineers and will be taken through the most important design steps of a well with power point presentations, class worked examples and individual/group exercises; the intent is to show them how the subsurface data are used to design a well.

Standard well engineering software will be used to familiarize the delegates with its outputs, and to help visualizing how the well design needs to change when inputs are varied.

During the second day of the course, the subjects will be targets definition and directional well planning (0.5 days); and drilling fluid specification (0.5 days).  At the end of the day, one hour will be spent reading drilling reports and deducting technical well engineering information from them.

During the third day of the course, the subjects will be kick tolerance with casing shoe setting depths (0.5 days) and casing characteristics (0.5 days).  At the end of the day, one hour will be spent reading drilling reports and deducting technical well engineering information from them.

Well Engineering For Non-Well Engineers Training Course

Ever wondered why, throughout the design of a well, objectives, trajectory and casing specifications are often changed several times, leading to unnerving loss of team-time, to changes in cost estimates and to procurement issues?

Is it sufficient to have a clearly mapped well design process, in order to avoid the shortfalls that will lead to re-designs and late changes, with cost and safety consequences?

Or instead, wouldn’t the well design process be swifter, if all the subsurface professionals knew what key decisions and data they are required to provide, at what point and for what design decisions?  Which means, if they could see the process from the eyes of a well engineer?

The purpose of this course is to explain what the engineering of a well entails, what the design decisions are, the reasons behind them and how the subsurface data are used in the well design process, with what consequences and what impacts on the well.

To do this, after giving a brief description on the mechanics of drilling a well, the course will mainly focus on the well engineering aspects related to the data coming from the subsurface team; the course participants, through technical explanations and design exercises, will “become” well engineers for three days and this will help them, once back to the office, to be more aware of the importance of their outputs to the well design process.  They will also learn to read drilling reports, which is a skill that will help them be more actively involved in the offsets reviews and in following the wells currently being drilled.

The professionals working in subsurface disciplines whose outputs are the inputs to the well engineering / drilling discipline, for example:

  • Geologists, whose work is an integral part of the well planning process by providing clear target definitions, suggestions on trajectory and anti-targets, learnings from offsets review geology, pore pressure predictions and fracture strengths for the determination of drilling fluid characteristics, kick tolerance and casing design load cases
  • Reservoir engineers, whose work is an integral part of the well planning process by determining well placement strategy (and therefore directional requirements for the well), compaction constraints and monitoring requirements (with obvious consequences to the completion design)
  • Production technologists, whose work is an integral part of the well planning process by leading to the completion requirements (and therefore shoe setting depths, casing characteristics and completion jewelry) and production load cases definition for the casing design process
  • Other subsurface professionals such as geoscientists (whose work defines for example the well conductor requirements and therefore has impacts on the casing design), bio-stratigraphers (whose work defines the strategy of casing setting depths and section picking criteria in the drilling program), etc.

The professionals working in disciplines adjacent to the well engineering / drilling discipline, for example:

  • Contract and procurement specialists, who will benefit from this course by getting a helicopter view on the materials and services that they procure, their role in the drilling activities and the impact of contractual details such as lead time and safety on well engineering and drilling activities
  • Financial and accounting managers, who will benefit from this course by getting a real insight on the drivers to the time and cost estimates that well engineers feed to them, and that are so important to the project finance.
