Stimulation/ Diverting Agents

To optimise a matrix or fracture acid job ideally the whole production interval should be treated. However, when this zone is massive or several sands are open to the wellbore, it can be necessary to perform the treatment in several stages. To do this, it is obviously necessary to isolate the zone to be treated from the others, and this can be done either mechanically using packers, or chemically using diverting agents.

These chemicals work in very much the same way as the fluid loss additives by bridging the pores in the formation. One important aspect of using diverting agents is the use of the correct material to avoid causing any damage to the formation. Lab testing is a great help in deciding which product is suitable for the application.

SDA-01 is a diverting agent for use in oil, gas and water injection wells. It is an organic material in flake form and is slowly soluble in water, acid, oil and gas.	SDA-01
SDA-02 is an oil-soluble resin available in fine, medium, coarse and granular grades for use in matrix acidising and aqueous fluid fracturing. It can be used at temperatures up to 250F.	SDA-02
SDA-04 is a waxy, off-white material used as a temporary blocking or diverting agent during well treating operations. SDA-04 can be used at bottom hole temperatures of 80 to 180F.	SDA-04
SDA-05 is a waxy, off-white material used as a temporary blocking or diverting agent during well treating operations. SDA-05 can be used at bottom hole temperatures of 80 to 145F.	SDA-05
SDA-06 is a waxy, off-white material used as a temporary blocking or diverting agent during well treating operations. SDA-06 can be used at bottom hole temperatures up to 200F	SDA-06
SDA-09 is a universal diverting material that may be used in treating or completion fluids for injection, disposal, oil and gas wells. It functions as a fluid loss additive and diverts at the face of the formation.	SDA-09
SDA-155 is a waxy off-white material used as a temporary blocking or diverting agent during well treating operations. SDA-155 can be used at bottom hole temperatures 155F+.	SDA-155
SDA-180 is a waxy off-white material used as a temporary blocking or diverting agent during well treating operations. SDA-180 can be used at bottom hole static temperatures of 180F+.	SDA-180
SDA-33 is a diverting material in liquid form for use in matrix acidising. When added to aqueous fluids, SDA-33 provides a dispersion of fine particles of a high melting point, oil soluble resin.	SDA-33
