Ideal Solution for Total Losses and Partial Losses in Cavernous Formation
Lost circulation problem is continuously occurring in the oil and gas wells. Lost circulations range from partial to complete which involve material-replacement, remedial operations expenses non-productive time costs and huge financial impact. Conventional solutions ranging from adjusting fluid rheology, pump rates to adding particulate materials to wellbore fluids but, these solutions do not always work. Many severe-loss treatments have been designed on a trial-and-error basis.
Thixo Cure Lost Circulation Solution is proven to help cure losses successfully, particularly severe losses.
CemDos™ Thixo Cure Lost Circulation Solution is designed to prevent cement fallback, promote early strength development, and control fluid migration during primary cementing applications. Our solution helps provide excellent compressive strength development and settling control. It is effective at temperatures from 30 °C to 90 °C.
- Short transition time
- Expansion properties
- Gas migration control
- Lost circulation control
- Prevents slurry fallback
Restored Lost Circulation During a Single Trip
Helping our customers solve problems is what we do best. Currently, there is no generic treatment known which will cure all lost circulation situations. Based on this fact, DOSAS provide a solution used to tackle the lost circulation problem. CemDos™ Thixo Cure Lost Circulation Solution helps manage lost circulation during cementing in cavernous or vuggy formations where bridging materials are ineffective.

High Gel Strength Cements
Thixotropic agent DosThiox™ 85 is lost circulation agrnt and is used to prevent lost circulation during slurry placement. DosThiox™ 85 is effective at temperature below about 90 °C. Very low concentrations of DosThiox™ 85 additive can be used at temperatures above 60 °C when only settling or free water control is needed.
