PROBLEM STATEMENT
4
PROBLEM STATEMENT (CONT.)
It includes some realistic constraints in the design
1. Achieve two dimensional reconstruction of the fluid passing
through the device with a minimal error accuracy of 10%
2. The device should provide a standard computer interface to a
General Purpose IBM-compatible computer (e.g. RS232, PCI,
or parallel interfaces)
3. The delay time required for data acquisition and image
reconstruction should not exceed 20 seconds
5
PROBLEM STATEMENT (CONT.)
It includes some realistic constraints in the design
4. Provide a Graphical User Interface (GUI) to display the
reconstructed image onto a screen
5. The algorithm for image reconstruction and data acquisition can
be embedded into any general purpose computer having 2 GB
hard disk and 256 Mbytes of memory (RAM)
6. The device should be powered with a standard power voltage
level (e.g. 24VDC and/or 220VAC)
7. The design should be operational before May 5th, 2011.

DESIGN SPECIFICATIONS
1. A two dimensional reconstruction image of the fluid passing
through a pipe can be constructed by manipulating the received
data from the electrodes
2. Only one of the electrodes can be excited at a time which
creates an induced voltage for the rest of electrodes
3. An analog multiplexer will be placed between the hardware
and software in order to receive the induced voltage and send
the output signal to the software
7
DESIGN SPECIFICATIONS (CONT.)
4. IEEE-488 control will be used as standard interface for sending
data to the computer
5. Serial interface RS232 will link the feedback provided from
the computer side to the analog multiplexer

PROJECT GOALS AND OBJECTIVES
 The main purpose is to build a strong theoretical and
algorithmic background on Tomography
 It aims to design a tomography system that consists of
capacitance arrays, front end analog electronics and digital
hardware architecture of the algorithm
 For efficient oil development, it is necessary to accurately
measure the products result from the oil wells.

SOLUTION APPROACH
 In order to produce efficient work:
o A schedule was designed that illustrates the tasks,
assigned team member, deliverables and deadlines
respectively
 A meeting will be held during the project at least once a
week among team members
 A meeting will be conducted with the instructor once a
week to ensure that the team is on the right track and
solve any problem that might appear
11
SOLUTION APPROACH
 In order to provide easy communication between the
team members and the client, Data Retrieved System (DRS)
is required.
o This system helps to keep in touch with the advisor
and all the team members.
 A website will be prepared with all project documents for
easy access by the team members and the client
12
DESIGN’S BACKGROUND
 Tools of solving:
o Forward methods (example: ECT)
o Inverse methods
 Previous solutions for monitoring pipelines:
o Optical sensors to distinguish gas flow
o Ultrasonic sensors to distinguish water and oil
13
ECONOMICS
Our project does not cost a lot because it needs:
o Few instruments
o Software codes (will be built by the team)
Improving the project in a future stage can help the device to
work as an early detector of fluid leakage  save the
company’s money
14
TESTING AND VALIDATION PLAN
 Hardware Testing
 Software Testing
 Software & Hardware Interface Testing
15
TESTING AND VALIDATION PLAN
 Hardware Testing
oInitial testing to match the practical results with the
theoretical concepts
o Make sure that the instrument is not affected by any
external interference and if it does, an screen layer has to
be provided
o Checking the instrument ability to withstand high
temperature and pressure
16
TESTING AND VALIDATION PLAN
Software Testing
o Software interconnection with the hardware
o Two software programs interface which are MATLAB
LabView programs
17
PROJECT SCHEDULE
 Different matrix and chart that set the details of the
deliverable of this project and their deadline have been
produced
 The Percent Complete Matrix designed to represent the
responsibility of each team member and help in keep track of
the project accomplishments
 The Gant Chart
18
FACILITIES AND EQUIPMENT
 For experimental purposes, we are using impedance analyzer to
measure the capacitance effect into two parallel plates
 In the hardware part:
o Pipe
o Number of electrodes
o Electrode multiplexer or analog multiplexer
 In the software part:
o Labview program
o Matlab program
19
BUDGET
The cost of the project will consist of two budgets
 The research budget which will almost cost of 100 $ will be funded by
Electrical Engineering department at the Petroleum Institute
 The products/equipment ordered from some vendors companies
*This equipment will provided by Electrical Engineering department at the Petroleum
Institute
20
REPORTING, MAINTENANCE AND
UPGRADE PLANS
 Submitting a weekly work-in-progress report (mints) to
update the client once the project has started
o Date of the conducted meeting
o Topics and the issues discussed during the meeting
o Tasks distributed with deadlines
o Brief description of each task
o Next topic to be prepared and meeting date
o Comments and important notes
21
REPORTING, MAINTENANCE AND
UPGRADE PLANS
 Having maintenance and upgrade plans report
o Details about changes made in case of any replacements
in certain parts with reasons of replacements, and how
effective these changes are
22
DELIVERABLES
 Full description of how each product will be produced and
handed for the client
23
SOCIETAL AND ENVIRONMENTAL
IMPACTS
 The design will help the oil industry to recover a huge
amount of oil savings
 Since we are using AC power to turn on our device, we can
use one of the renewable energy sources to minimize the
effect on the environment by using DC to AC convertor
24
PROFESSIONAL ENGINEERING
ETHICS
 Engineering ethics is one of the most important issues in
any engineering project
 Ethics’ codes were produced as a reference during the
project
 The only main highlighted ethical issue that is involved in
this project is the “copy-right” issue since this project will
include different software programs from different companies
25
SUSTAINABILITY
 All the documents, that include the technical descriptions
of the hardware and the software as well as the prototype
results, will be saved in a CD as a softcopy backup for both
the client and the group
 Two softcopies can be uploaded in both a special EE
program webpage and internet blog
 Another way of documenting is by installing the prototype
in one of the workshop with a hardcopy manual
26
MANUFACTURABILITY
 The final report will include all the product specifications,
conditions and the operation method
 The operator health and safety which is considered as a
very important document in manufacturability
27
HEALTH AND SAFETY
 Each member should fully understand the lab safety rules
document written by EE department
 The presence of the project supervisor is required when
implementing the design at the first time
28
MANAGEMENT
 Formal and informal meetings with the Project
Supervisor
 Formal report
