Halliburton's exclusive Micro Matrix® cement now offers solutions to specialcementing problems that have beset operators for many years. When you're faced withsuch challenges as how to obtain the needed compressive strength across a low-strengthwater zone; or how to seal off a microannulus smaller in cross-section than a typicalcement particle; or even how to get the needed compressive strength when the BHCT isonly 40°F, as in a subsea completion, Micro Matrix cement will provide the solution youneed. And that isn't all. Micro Matrix cement can be your solution anytime you need alightweight cement, a cement to penetrate extremely small spaces, or a cement with highcompressive strength.

Micro Matrix Cement Represents a Major Advance inPrimary and Squeeze Cementing Technology

• Develops high early compressive strengths at low temperatures.

• Penetrates and helps seal areas normally inaccessible to oilfield cements.

For Squeeze Cementing, Micro Matrix Cement Helps RepairLeaks and Correct Other Problems

Micro Matrix cement has proven to be ideal for sealing casing leaks. Its penetratingability and strength characteristics offer a distinct advantage over regular cement invirtually every squeeze application: controlling water or gas flow, sealing thief zones,repairing leaks, and facilitating abandonment.

Micro Matrix Cement Also Offers UniqueProperties for Primary Cementing

For any primary cementing application requiring a high-strength, lightweight slurry, Micro Matrix could be yoursolution. Also, WOC times with Micro Matrix cement maybe reduced by as much as 50% at low temperature ascompared to premium cement.

Micro Matrix cement expands slightly on hydration andoffers significantly better bonding strength than typicalcement at low temperature. And, Micro Matrix is versatile,compatible with virtually all of Halliburton's proven cement additives.

Ultrafine Cement Technology: TheBreakthrough Innovation That ProducedMicro Matrix Cement

Micro Matrix cement is micro ground so that the particle size is 10 or more times smaller than standard cement.This smaller particle size has been particularly useful forremedial cementing where penetration of small cracks isrequired, and for wells completed and produced that develop high permeability streaks resulting in adverseproduction economics.

Standard cement slurries, because of their greater particlesize, are unable to produce more than a skin effect followinga squeeze procedure. Micro Matrix cement, on the otherhand, has been proven to penetrate small channels, thushelping shut off undesired water, gas, or steam production.

Micro Matrix Cement—One More Reasonto Call Halliburton for AdvancedCementing Solutions
