DIRECTIONAL DRILLING
& SURVEYING
Course Overview
Aims & Objectives
Directional Drilling is one of the most fascinating subject areas in the oilfield – with high tech tools able to
drill into the smallest of targets great distances from the rig.
The course learning outcomes are:-
To enable delegates to understand why points on the Earth (e.g. Geographic North, Magnetic North,
Latitude & Longitude, UTM co-ordinates) have been referenced as they have;
To enable delegates to understand why certain survey tools reference certain points of reference (e.g.
magnetic tools / MWD, gyroscopic tools, inertial navigational tools etc.) and how positional calculations
are carried out;
To e a le delegates to k o hat goes o i side la k o soft are sur e progra s; To learn why – and how – directional wells are designed as they are: Vertical, KOP, Tangential Section,
Horizontal & Multi-lateral;
The tools used for directional, horizontal and multi-lateral drilli g a d ho the are used, e.g. PDM s, turbines, rotary steerable systems, whip-stocks etc.;
How the Directional Drillers & MWD Engineers drill from the vertical to the target(s) selected by the
Operators su -surface groups. Tool Face, High Side, Inclination, Azimuth, Measured Depth & TVD.
The following media are used during the course:-
1) Lectures (the Trainer began his career 35 years ago as a Drilling Engineer and has designed and been
involved with hundreds of directional wells worldwide on land rigs, jack-ups, platforms and semi-
submersibles);
2) PowerPoints (written by the Trainer);
3) Videos & Digital Film
4) Calculations & Manuals
The aims and objectives of the course are for delegates to understand how directional wells are planned
and how the tools used work. We will also go through Minimum Radius of Curvature Programs to
establish wellbore positional uncertainty.
Provision is also made for delegates to discuss any directional aspect of their up-coming wells which are
perti e t to their e plo er s proje ts i order to attai su ess ot just first ti e – but every time.

DAY ONE
THE EARTH
.
The Earth’s Magnetic North Pole is in North East Canada and Varies in Position
SURVEYING
During this introductory session you will gain an understanding
of why we survey oil and gas wells, how we reference various
points on the Earth and variations – such as magnetic variations
for example. We will cover the following subject areas:-
Why Survey?
Models of the Earth
The Geoid
The Spheroid
Grid Systems
Universal Transverse Mercator Grid (UTM)
Lambert Conformal Conic Projection
Other Grids
Magnetic Declination
Mapping Grids
SURVEYING TOOLS
There are a variety of surveying tools for a variety of purposes,
and in some parts of the world (e.g. on low day-rate land rigs for
example) old Tot o s, Single Shots and Steering Tools are still run.
At the other end of the spectrum, very high accuracy inertial
navigation systems are run, similar in spatial accuracy to modern
day aircraft systems. In this section we will cover the following
subject areas:-
Tool Selection Factors
Magnetic Tools
Photographic Magnetic Survey Tools
Magnetic Single Shot
Magnetic Single Shot Reading 5 ½ Deg. Inclination
South 36 West Azimuth (Raw)
Magnetic Drop Type Survey
Magnetic Multi-Shot
Magnetic Multi-shot (R) run in Non Magnetic Drill Collars (L)
Electronic Magnetic Multi-shots (EMS)
Gyroscopic Survey Tools
Gyroscopic Single Shots
Gyroscopic Multi-shots
Surface Read-Out Gyro
Ring Laser Inertial Guidance System (RIGS)
MWD Systems
Magnetic Interference
Lines of Magnetic Flux Vary in Intensity Around the Globe
