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 7 09/03/2013

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 8 09/03/2013

Failure analysis (1 of 3) Systematic use of the compound and following the procedure ensures: � That 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 9 09/03/2013

Failure analysis (2 of 3) � Application using a brush gives uneven distribution and allows contamination: with conseguent 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 10 09/03/2013

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 11 09/03/2013

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.

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 13 09/03/2013

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 from Off Shore installations and into the ground from On Shore installations.

Thread Compound Background (1 of 2 ) 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 : Protection of metal to metal contact and 1) seizing up in situations of high stress; Secure seal against high internal 2) pressures. DOPE DIFFUSER 15 09/03/2013

Thread Compound Background (2 of 2 ) 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. DOPE DIFFUSER 16 09/03/2013
