Dennis Energy Services, Inc. DESI SEALMCT-1000 FINE(
Mud Circulation Treatment - Fine Grade Cellulose Material ) DESI SEAL MCT-1000
FINE ( Mud Circulation Treatment ) is a uniquely
formulated product designed to seal permeable formations of all types, in water,
oil and brine water. Formulated
from a combination of available cellulose fibers. MCT 1000 encompasses a wide range of particle sizes
and shapes. In order to increase
the flexibility of MCT 1000 both fibrous and granular cellulose
materials are incorporated. All
components in MCT 1000 are compressible and deformable allowing them
to confirm to the shape of pore spaces and fractures. MCT 1000 will
form a seal near well-bore, minimizing fluid invasion an proportionately reduce
cake build-up. A combination of MCT
1000 and MCT-500 can handle problems from differential sticking
to lost circulation MCT 1000 is most effective when used alone or with
Gilsonite material. BENEFITS: Minimizes differential
sticking; seals micro-fractures; can help prevent loss circulation or heal it;
minimal rheological effect on fluids; compatible with water, oil or brine
fluids; minimizes formation damage from fluid invasion; easily removed from
productive formations; thermally stable; environmentally safe and non-toxic;
non-damaging to MWD tools. GENERAL APPLICATION
PROCEDURES: Seepage Loss: Mix MCT 1000
in a pill at concentration of 8-15 ppb and sweep the wellbore periodically. When
chronic seepage is occurring at a system treatment of 4-8 ppb is recommended.
System maintenance can be achieved by incorporating subsequent sweeps. Lost Circulation: Mix DESI SEAL
through the chemical hopper in a pill containing 60% MCT 500 and 40% MCT
1000. Fluid density will determine the total concentration that can be
mixed. Total concentrations of 25-65 ppb are common. After circulation is regained a MCT 1000 / MCT
500 sweeping program is recommended to maintain the integrity of the seal
during the drilling operations. Differential Sticking
Prevention: Prior to drilling
depleted zone add 2-4 ppb MCT 1000 to the system.
Mix a pill containing 8-15 ppb MCT 1000 and 8-15 ppb Gilsonite
material. Sweep the hole as new
sands are drilled and every 4-6 hours depending on hole conditions.
Sweep the hole prior to tripping, logging, or running casing. Brine Fluid Pills: Vicosity fluid with
polymer to +/- 40 sec./qt. Add 15-25 ppb MCT 1000 through chemical
hopper. Spot pill across area to be perforated or point at which hole is taking
fluid. MCT 1000will
minimize fluid invasion into the formation.
MCT 1000 is easily removed from formations during production
and will biodegrade naturally. Physical Characteristics: Form
