Class Rules
If there is anything you do not understand during
the lectures, say so. We constantly build onideas so if you do not understand the basics youwill soon be lost
We will break every hour or so. Please return onschedule in consideration for the others.
Computers are to be on the honor system during
lectures. Check you mails on breaks.

WHAT THIS COURSE IS AND IS NOT
This will not make you a DE in a WeekAimed at giving you the concepts
Allows you to understand how Cementing
Fits into the larger process
Provides a basis for understanding whatyou will see on rigs and in client offices

Well Construction
The process creating of a hole in the ground, forthe finding or exploitation of natural resources.
Mines are holes dug to find valuable minerals. We
efficiently remove the overburden to get at the ore-
body
Wells are holed drilled to find valuable liquids or
gases (Gas, Oil, Water, Helium, CO2 etc). Weefficiently remove the overburden to get at the liquid
for extraction

Well Construction
A construction project to build a hole inthe ground
To Build the hole we must understand
The material we are building in (the Earth) The material we are building with (Steel)
The Hole Construction Equipment (Rig)
The services and subcontractors needed toefficiently execute to plan (SLB and others)

Drilling is a repetitive Process
Drill a hole until the earth is no longer
strong enough to support the loads that youare imposing
Evaluate the hole you have drilled by
looking at the dirt, using electrical logs,cores and samples
Run and cement protective casing toreinforce the earth and allow drilling toproceed

The Overall Drilling Process
Prepare location for rig Dig cellar Dig Pits install liners Install conductor pipe Prepare support pad for
rig, camp etc Build roads, fencing, dig
pits Sometimes drill water
well
Move rig on to location, rigup and prepare tostart drilling.

Setting Conductor
Large, thick walled pipe drilled, jetted
or driven in to the groundPurposes;
1. Supports the weight of the well and
BOPs etc.2. Prevent washing out surface soil so
the well can be circulated
3. Formations are weak no well iscontrol possible
![Page 14: Lecture One Introduction and Rig Basics](https://reader031.vdocuments.mx/reader031/viewer/2022021322/577d39331a28ab3a6b9948bc/html5/thumbnails/14.jpg)

Drill Surface Hole
Drill a hole through the conductor
Drill until
1. Formations cannot support the hole2. Deeper formations have pressures
higher than the strength of the rock
at the top
![Page 15: Lecture One Introduction and Rig Basics](https://reader031.vdocuments.mx/reader031/viewer/2022021322/577d39331a28ab3a6b9948bc/html5/thumbnails/15.jpg)

Set Surface Casing
Pull Bit out, Run Casing in And Cement
1. Install a Wellhead
• Support axial loads, isolate the annulli and
casings from each other
2. Install a blow out preventer (BOP).• Plan will control formations not divert them
3. Casing protects freshwater sources.
4. Reinforces the rock allowing moredrilling

Drill Intermediate Hole
Drill through the Surface pipe to
extend the well
• Directional work is often used
• While drilling possibly cut cores
• After drilling Run electrical logs,
Sidewall cores etc to evaluateformations
![Page 17: Lecture One Introduction and Rig Basics](https://reader031.vdocuments.mx/reader031/viewer/2022021322/577d39331a28ab3a6b9948bc/html5/thumbnails/17.jpg)

Run the Intermediate Casing
Run the casing and cement the
annulus.Note that each casing is smaller
than the previous one.
1. Increased shoe strength to drill
ahead.
2. Protect drilled hole.3. Protect any oil and gas found

Production Hole Section
Drill remaining overburden and into
the main pay sectionsPurposes:
1. Penetrate the reservoir.
2. Allow sufficient over-hole toprovide a sump (logging tools,
casing, drop guns etc)
3. Logs are run to evaluateformations
![Page 19: Lecture One Introduction and Rig Basics](https://reader031.vdocuments.mx/reader031/viewer/2022021322/577d39331a28ab3a6b9948bc/html5/thumbnails/19.jpg)

Run Liner or Casing
Cement a liner in to the reservoir.
Liners are partial casing strings
Run for economics where the main
casing is strong enough but the
formations below are not
Liners are run on Drill pipe and “hung”
on modified packer systems cemented
through the drill string to provideisolation

Drilling & Casing; Completion
Run completion tubing.
Perforate the production liner.
Purposes:1. Allow hydrocarbon production.
2. Form a conduit for tools to be run.

The Complete Well
Concentric strings of casing
Sealed at the top using mechanical
packoffsSealed at the bottom and in the
annulus using cement
Innermost string is the production
string, and is usually perforated to
allow production
A packer and tubing string are run
inside the P Csg.
