DEL PHALT

 

 

 

FUNCTION:

 

GENERAL DESCRIPTION:

 

A superior water soluble sodium sulfonated asphalt which excels in controlling fluid loss, especially down hole HTHP fluid loss.  The very tough, thin filter cake created by Del Phalt reduces mud filtrate.  Filtrate is inhibitive which minimizes damage to water-sensitive shale formations and drill cuttings.

 

 

 

 

 

 

 

An asphalt made water soluble by sulfonation process.  It is an exceptionally versatile drilling mud additive used primarily for shale control and lubricity.  It contains no fillers such as The causticized lignite, resins or gilsonite.  It can readily be added to water base muds that contain oil or lubricants without "greasing out."  Del Phalt is + 85% soluble.  It is also beneficial when used in oil based mud.
PRODUCTS BENEFITS:

4.  Controls high-temperature water 
     loss.

5.  Produces thin, strong filter cake.

6.  Compatible with water base and 
     oil base fluids.

Bulk Density: 50 lbs=1.46 cu.ft.

Appearance: dark brown to black 
                     powder

Odor: slight

Solubility in water: +85%

Specific gravity: +1.23

TYPICAL TREATMENTS:

 

1.  System treatment 2 to 6 ppb

2.  Pill application: 10 to 25 ppb 

(A pill containing 15 ppb Del-Phalt and 8 to 12 ppb Del-Fiber fine can be applied in a sweep fashion to reduce mud seepage loss, stabilize shale sections, seal low pressure sands or to coat, seal and lubricate the wellbore prior to logging or running casing.  To spot a pill across a troublesome zone while tripping, logging or running casing use 15 pb Del-Phalt and 5 to 8 ppb Del Fiber fine.)

 

 

Mixing Requirements:  Conventional hopper is adequate unless chlorides exceed 
                 60,000 ppm in which case, pre-wetting with fresh water is recommended.

Special Information:  Del-Phalt is consumed on drilling solids and on the well bore.  It is advisable to add 20-40% more Del-Phalt 24 hours following the initial treatment.
