Cement Mud Flush

Franklin Cement Mud Flush is a synergistic, anionic blend of surfactants specifically formulated for water-based spacer fluids in cementing applications. When used as a spacer ahead of cement slurries, Mud Flush helps to improve the bond of the cement to casing by boosting the cleaning action of the spacer and rends the casing water-wet.

Cement Pump

Due to the high number of zones that are close together, the Illinois Basin is one of the toughest places to get good zone isolation when cementing the production string. Cement density control when pumping a production string is essential to the success of the job.

Franklin High Yield Cement (FHY)

In most areas throughout the Illinois Basin, the need to have the cement circulated to surface on a production string is a must. Higher density slurries are utilized to isolate the producing zones down the hole. Due to the low fracture gradients down hole, it is impracticable and not cost effective to utilize these higher density slurries all the way to surface. Placing high density slurry all the way to the surface would result in loss of circulation. Light weight filler systems are used to replace the higher density slurries and supply much less hydrostatic pressure on the slurry column.

Franklin Latex (FLAC)

Fluid loss in cement occurs across permeable formations under pressure. The aqueous phase of the cement slurry decreases, which causes the slurry density to increase and change slurry rheologies. If sufficient fluid loss occurs, the slurry can become unpumpable.

Franklin Thix-O

Franklin Thix-O is a thixotropic cement slurry which is often used in wells where excessive fallback of the cement column commonly occurs. These wells have one or more zones with low fracture gradients which will fracture and allow loss of the slurries. Once Franklin's Thix-O slurries stop moving, it very quickly gains gel strength and becomes self-supportive in the annulus, preventing slurry loss.

Franklin Salt System (FSS)

Throughout the Illinois Basin, most wells have several zones on interest to complete. Obtaining reliable zone isolation during the primary cement job is crucial to the success of the well. Even when proper cementing practices are followed, such as proper casing centralization and removal of the mud cake during the cement job, you may still have a micro-annulus between the cement and the casing.

Micro-Fine

Finding a small casing or collar leak during MIT testing is a common occurrence. To correct the problem, conventional cement squeeze techniques using A.P.I. cement slurries are ineffective in plugging small leaks in casing such as collar leaks. This is due to conventional cement particles being larger than the area they are trying to penetrate. When pressure is applied to the slurry, the water is squeezed out, dehydrating the cement and causing squeeze failure.

Right Angle Set Cement (RAS)

Right Angle Set Cement (RAS) is a low temperature cement system generally designed for the use between 32º F and 90º F. It can be retarded for use up to 125º F with proper testing. RAS develops very good compressive strength of the slurries even at low temperatures. RAS is primarily used to stop extreme lost circulation and/or extreme water flows.

Super Zone Control

Zone Control and Super Zone Control are specifically formulated for water-based spacer fluids in cementing applications where lost circulation has been encountered while drilling or anticipated during cementing operations.
