Oil Well Basics
Oil well is a drilled hole (1000-15000 deep)
3-10 in diameter. It is cased all the way
through. Pipe has holes for oil mixture
inlet. Oil saturates formation. It resides in
pores of some solid earth regions.

Introduction to Oil Well Logging

• Well logging is an ordinary process in oil well
  development. It is also used in water wells.
• It is essential to know approximate porosity,
  permeability and oil concentration in the earth
  around the well

Problem

• 730,000 wells in the USA producing lt1200/day
  (10 of oil used in USA)

• No technology to fit these small wells. Industry
  leaders like Schlumberger have tools fit for
  12000/day wells.
• Stripper well owners normally cant afford to
  rent well logging technology.

Taylors Grant Goals

• Cheaper technology that can be used easily by
  stripper well owners
• Nuclear detector tool
• Video Camera
• Portable Winch system
• Pressure Sensor

6
Work and Testing Done

• Nuclear detector prototype built and lab tested
• Prowex tool structure built and tested under
  150psi liquid pressure

Objectives

• To design and build a system that can handle the
  weight of using a winch for down oil well
  operations.
• The winch has to be able to hold at least 1000
  feet of cable.
• It also has to be motor-operated for ease of use.
• The system has to be stable.
• The optical encoder has to be accurate to within
  an inch.
• It has to be lightweight

8
Figuring out a Design

• Figure out whats cheap, lightweight and sturdy

Optical Encoder
11
Making a Model

• The same material as the Science Building Model
• After the Model we changed the design

12
Future Work

• Build the system
• Figure out all the wiring
• Finish figuring out the motor
• Testing
