Conversion Factors
1 Bar = 14.5 psi
1 kPa = 0.1461 psi
1 Atmosphere = 14.7 psi
1 kg/sq m = 0.20 lb/sq ft

1 meter = 3.28 feet
1 foot = 0.30 meter
1 cu ft = 7.481 US Gallon
1 US Gallon = 231 cu ins
1 US Barrel = 5.6146 cu ft
1 US Barrel = 42 US Gallon

7. PRESSURE BASIC & BASIS
1Fundamentals of Fluids & Pressure
Pressure is defined as Force per unit area exerted by fluid i.e.
Pressure = Force ÷ Area
Using  concept, the formula can be changed:
Force = Pressure × Area
Area = Force ÷ Pressure
2 Basic laws of physics concerning fluids & gas
•Liquids are not compressible
•Gases are compressible
•Liquids & gases are both FLUIDS
•Pressure in a fluid is transmitted equally in all directions.

7 Basic Wireline Operations / M.F.Radwan

8. PRESSURE BASIC & BASIS
3 Fresh Water
Fresh water weighs the same per unit volume anywhere in the world that is why it’s
called “Universal Fluid”& used as STANDARD for comparison with other
fluid.
Fresh Water Facts:
•Density of 62.4 lbs/ft
3
•Density of 8.33 lbs/gal
•Density of 7.48 US gal/ft
3

•PG of 0.433 psi/ft
•SG of 1
•API 10º
PG = Force (Density/ft
3
) ÷ Area (ins
2
)
= 7.48 gal/ft
3
÷ 144 ins
2
= 0.052 psi/ft
= 62.4 lb/ft
3
÷ 144 ins
2
= 0.433 psi/ft
Relationship between Density (ppg) & PG
(psi/ft) is always the same  0.052 is used as
constant for any calculation between them.
Formula of Density (ppg) = Density (lb/ft
3
)  Density (US gal/ft
3
)
 Density (ppg) = 62.4 ÷ 7.48 = 8.33 ppg
Formula of fresh water PG if density in ppg is given,
= 8.33 ppg × 0.052 (constant) = 0.433 psi/ft PG = Density (ppg) × Constant
8 Basic Wireline Operations / M.F.Radwan

9. PRESSURE BASIC & BASIS
4 Specific Gravity (SG)

The ratio of the density of a substance compared to density of another substance
which is used as the standard (Fresh Water).

Many fluids in petroleum industry is expressed in SG as well as in wt ppg. It’s
necessary to convert SG to PG to find HP.

To find SG of fluid simply divide fluid wt by fresh water wt.
E.g. Salt water wt is 10 ppg.
 Salt water SG = 10 ppg ÷ 8.33 ppg = 1.2

To find PG of fluid simply multiply fresh water PG by fluid SG

E.g. Find the HP of brine at 5000 ft TVD with brine SG of 1.17.
HP of brine = 1.17 × 0.433 psi/ft × 5000 ft = 2533 psi
9 Basic Wireline Operations / M.F.Radwan

10. PRESSURE BASIC & BASIS
5 API Gravity

API gravity is another value used to express relative wt of fluids & was introduced by
American Petroleum Institute to standardized the wt of fluids at base
temperature of 60º F. Water as standard fluid had been assigned the value of
10º API gravity.

To convert API gravity to SG, the following formula is used.
SG = 141.5 ÷ (131.5 + APIº)

E.g. Find the SG of 30º API oil
SG = 141.5 ÷ (131.5 + 30º)
= 141.5 ÷ 161.5 = 0.875
10 Basic Wireline Operations / M.F.Radwan

11. PRESSURE BASIC & BASIS
6 Hydrostatic Pressure (HP)

HP is the pressure developed by column of fluid at given TVD. “Hydro” means fluid & “static”
means stationary.  HP is pressure created by stationary column of fluid.

To calculate HP in psi of any fluid simply multiply TVD in ft by PG of fluid.

E.g. Find HP in psi of fresh water at 500 ft TVD.
HP = 500 ft × 0.433 psi/ft
= 216.5 psi

To calculate HP in kPa of any fluid simply multiply TVD in meter by SG by 9.81

E.g. Find HP in kPa of brine with SG of 1.32 at 1800 m TVD.
HP = 1800 m × 1.32 × 9.81
= 23 308.56 kPa
Bar = 23 308.56 kPa ÷ 100
= 233 Bar

To find BHA of 2 fluid column or more simply add the HP of the fluid column of the same unit
of measurement together.

7 Case Study

What is the differential pressure in psi exists between the tubing & annulus at the
SSD assembly located at 8960 ft MD (8200 ft TVD) in the tubing?

Available Information:
The tubing/casing annulus is filled with 9.2 ppg brine full.
The well is S/I at surface with CITHP of 600 psi.
There is a gas cap of 0.6 SG gas down to 4000 ft fluid level
32° API oil from fluid level’ to 12000 ft.

Steps:
1 Sketch your information.
2 Calculate HP @ 8200 ft TVD brine in annulus
3 Calculate HP of gas cap @ 4000’
4 Calculate HP of oil column from 4000 ft to 8200 ft
5 BHP of tubing @ SSD, Gas HP + 32° API oil HP
6 Calculate the differential pressure at 8200 ft.

14. Case Study

1 HP of brine in annulus; = SG × WPG × TVD
HP = 9.2  8.33 × 0.433 × 8200
= 3919.6 psi

2 HP of gas = CITHP × GCF
GCF from table = 1.087
CITHP x GCF = 600 × 1.087 = 652.2 psi

3 HP of oil column; = SG × WPG × TVD
HP = 141.5  (131.5 + 32° API) × 0.433 × 4200
= 1573.9 psi

4 BHP in tubing @ SSD = 652.2 + 1573.9 = 2226.1 psi

5  Differential Pressure @ SSD = Annulus HP – Tubing BHP
= 3919.6 - 2226.1
= 1693.5 psi

Direction of flow is from Annulus to Tubing.

61. What is Slickline
Small diameter wire with sufficient strength to accomplish the
operation without breaking – why small?

Minimize the load of its own weight

Minimizing the cross-sectional area reduces the effect of wellhead
pressure

Enables the use of smaller diameter spools, reels and sheaves without
overstressing the material when bending

created whenever wire
deviates from the a
straight line condition

sheave size is the most
common reason for line
failure
14 bending cycles to run
in and out of the hole

Units are broken into two different hydraulic
drive systems, open or closed loop

Open loop - The open loop system has been
in use for several decades and provides a
good control of the line force over line speed

Closed loop - This type of system has a more
refined approach to the control of Line speed
over line force

3Pressure Testing
•Max CITHP + Safety Factor (500 psi) & apply in stages.
•PT medium; 60:40 ratio by volume of fresh water & glycol respectively.
(This would prevents “Emulsion” formation in oil wells or “Hydrates” if it
would be discharged into wells)
De-Pressurize
•Bleed off through production process venting system.
•If not possible, bleed off with extreme care, no personnel & source of
ignition down wind.
•De-pressurizing must be a Controlled Operation.
•PATIENCE is the virtue of this case & NO ACCELERATION is
permitted. Ensure that equipment is earthed to prevent ignition by
static electricity.

Wireline Philosophy:

“Achieve WL Objective with Minimum Run”
172 Basic Wireline Operations / M.F.Radwan

173. Safety Management at Workplace
1. Attitude
- Awareness of one’s action on health, property & environment all day &
everyday.

2. Anticipation
- Expecting or predicting dangerous situations & allows you to be
prepared.

3. Hazard Identification
- Source of danger.

4. Risk Assessment
- Probability that hazard may cause damage, loss or injury.

5. Risk Control & Implementation

6. Review
- Continual updating.

174. Safety Management Tool
Work Permit
Manage & control risks related to individual work tasks.
Control work activities in order to prevent incidents due to interface work
conflicts.
 Provide clear information to eliminate misunderstanding of work tasks hazards.
 Document appropriate approvals.
 Communicate activities to all affected personnel.

Work Permit Provides:
Nature of work

179. Hydrogen Sulphide (H
2S)
H
2S Characteristic

Deadly – Extremely Toxic Gas.

Colorless

Heavier than air, tends to settle in low lying areas.

Readily dispersed by wind movement or air currents.

Odor of rotten eggs only in low concentrations rapidly deadens the
sense of smell.

Highly corrosive to certain metals.

More deadly than Carbon Monoxide (CO), and almost toxic as
Hydrogen Cyanide (HCN) gas.
Guidelines for Working in H
2S Environment

 A pre-work safety briefing must be held in which all departments
concerned should be involved, Job Safety Analysis (JSA) is to be
exercised in this pre-work meeting.

 All persons involved in the work shall be conversant with H
2S
procedures for recognition, escape, and first aid treatment.

 Barriers and warning notices must be erected and PA
announcements made as appropriate.

 A job site H
2S monitor will be provided and personnel involved in the
work shall be conversant on the uses of this monitor.


 The responsible person planning the work and organizing the
worksite must be aware of wind direction and prevailing weather
conditions throughout the duration of the job.

 A sufficient number of Breathing Apparatus (BA) sets must be readily
available at the worksite.
