DOPE DIFFUSER 08/04/2013 7

Description

The Dope Diffuser is used in running completion to obtain an even distribution of a weighed quantity of the COMPOUND on the threads

It is also particularly suitable for the drillpipe, giving unquestioned logistic and economic advantages

DOPE DIFFUSER 08/04/2013 8

OPERATION

Once the Tool Spread is positioned

in the box only a few seconds are

needed for even calibrated

distribution of the compound on the

surface of the threads

DOPE DIFFUSER 08/04/2013 9

Failure analysis (1 of 3)

Systematic use of the

compound following the

procedure ensures:

Human error in using the compound in the wrong way is reduced to zero when there are a number of buckets on the rig floor.

DOPE DIFFUSER 08/04/2013 10

Failure analysis (2 of 3)

Application using a brush gives uneven

distribution and allows contamination: with

resultant seizure and loss of the thread ;

The Dope Diffuser protects the compound

from foreign bodies as it is enclosed in the

distributor and eliminates the risk of brushes

falling accidentally down the well.

DOPE DIFFUSER 08/04/2013 11

Failure analysis (3 of 3)

The compound has a lubricating power

corresponding to a precise screwing torque.

NEVER add oil or diesel fuel to improve the

spreading characteristics as this changes the

power of the lubricant.

The Dope Diffuser mixes the compound

eliminating the gravity separation of heavy

metals from oil and grease.

DOPE DIFFUSER 08/04/2013 12

Economic analysis

With the Dope Diffuser savings are made:

The quantity is measured out for the

connection only and excess application

as in the traditional method is

eliminated.

The excess that usually falls down the

well creates blockages that make it

difficult (and expensive) to send down

work-over or drilling equipment.

DOPE DIFFUSER 08/04/2013 13

Safety Analysis

The compound no longer SPILLS over the rig floor because the entire application process is enclosed;

This keeps the work area clean which is of basic importance for safety and stops the operational personnel from slipping .

DOPE DIFFUSER 08/04/2013 14

Environmental Impact Analysis

The elimination of spills is also essential

for respect of the environment;

The Dope Diffuser prevents anything from

the greasing process from falling into

the sea in Off Shore installations and

into the ground On Shore.

DOPE DIFFUSER 08/04/2013 15

Thread Compound

Background (1 of 3)

Historically the compound used both in drilling and production consisted of lubricating grease made from petroleum and containing heavy metals such as LEAD, ZINC, COPPER for:

1) Protection of metal to metal contact and seizing up in situations of high stress;

2) Secure seal against high internal pressures.

DOPE DIFFUSER 08/04/2013 16

Thread Compound

Background (2 of 3)

Ductility and malleability are advantageous

properties of LEAD, ZINC and COPPER,

allowing them to:

1) Compact and deform without fracturing

and prevent wear and damage to metal

surfaces;

2) Form an effective seal between the

threads and/or shoulders of the

connections (pipes and drill pipes)

DOPE DIFFUSER 08/04/2013 17

Thread Compound

Background (3 of 3)

The compound

OCCUPIES the spaces

between the tips and

roots of the threads AND INFILTRATES

between the contact

surfaces of threads and

shoulders, under

screwing torque before

and after drilling.
