- Diaseal M® Lost Circulation Material
Diaseal M® Lost Circulation Material
Diaseal M® LCM is a highly effective, high-solids, high-fluid-loss lost circulation squeeze material. A solid plug is formed in the thief formation when water or oil is squeezed from slurry. Diaseal M® LCM creates a seal in the loss zone, not in the wellbore like conventional LCM. The seal cannot be easily disrupted by circulation or drillpipe.

Drilling Specialties’ experienced personnel can help you design a Diaseal M® LCM squeeze to fit your particular application. In certain instances field service engineers are available to travel to your location for on-site field assistance. Diaseal M® LCM has been used successfully since 1964 on thousands of wells combating lost circulation throughout the world. Diaseal M® LCM is highly effective in both water based and oil based mud applications. Diaseal M® LCM can also be mixed with cement to gain a small amount of compressive strength, adding to the longevity of the squeeze. Make Diaseal M® LCM your first line of defense in solving lost circulation problems.

Advantages
  • Very dependable and easy solution to lost circulation problems
  • Does not contaminate drilling mud
  • Not necessary to bypass shale shaker
  • No risk of cementing up drillpipe
  • No risk of sidetracking hole (as with cement)
  • Use instead of conventional LCMs
Application Material Needed
Open hole lost circulation squeeze when open hole volume is 50 bbl or less Mix specified amounts of water or oil, Diaseal M® LCM, barite and LCM for 100 bbl of Diaseal M® LCM liquid volume
Open hole lost circulation squeeze when open hole volume exceeds 50 bbl Mix specified amounts of water or oil, Diaseal M® LCM, barite, and LCM for an amount of slurry equal to twice the open hole volume (if practical)
Lost circulation squeeze through perforations Mix specified amounts of water or oil, Diaseal M® LCM, casing leads barite, and LCM for 50-100 bbl of slurry volume

Follow recommended mixing, displacing and squeezing procedures for best results

 

 Cost

Less than cost for building new mud volume in most instances. Rig time spent on lost circulation problem is usually reduced. An extremely cost-effective material and procedure for remedying lost circulation.

Mud Types

All water-based, mineral oil-based and invert emulsion muds

Mixing Requirements

Clean mixing tank at rig or liquid mud plant. Cement company pump truck may be needed for low-volume pump rates. When oil is used and weighted with barite, an oil-wetting agent is needed to promote oil wetting and dispersion of barite. Otherwise, extremely high viscosity may develop. Generally, 0.5 ppb oil-wetting agent is plenty.

Desired Solids Control Equipment

No special requirements 

Handling

For specific instructions on handling, refer to the MSDS.

Packaging

40-pound multiwall paper sacks
