THE ULTRA SEAL ( PLUS ) IS A PROPRIETARY BLEND OF FIBROUS, GRANULAR AND FLAKE MATERIALS DESIGNED GRANULAR AND FLACK MATERIALS DESIGNED SPECIFICALLY FOR MASSIVE LOSS OF CIRCULATION, THIS PRODUCT WAS FORMULATED TO EXPAND THE EXISTING POSITIVE QUALITIES OF THE ULTRA SEAL PRODUCT LINE.
THIS PRODUCT IS FOR SEVER LOSS CIRCULATION CONTROL THE ULTRA SEAL ( PLUS ) IS A BLEND OF ULTRA SEAL (XP) , ULTRA SEAL (C) AND ADDITIONAL LARGER PROPRIETARY SEALING AGENTS, THIS BLEND EXPANDS THE SUPERIOR RANGE OF PARTICLE SIZE THAT ARE CONSISTENT WITH THE EXISTING PRODUCT LINE.
THIS LARGE PARTICLE ARRAY IS BENEFICIAL ON ESTABLISHING A STRONGER INITIAL BRIDGE ACROSS THE THIEF ZONE.
THUS ALLOWING TIME FOR THE SPECIALIZED FIBERS FOUND IN THE ULTRA SEAL (XP) AND ULTRA SEAL (X) TO FILL ANY REMAINING MICRO-FRACTURE THAT MAYBE PRESENT BY THE INCLUSION OF THESE LARGER PARTICLE EFFECTIVE CONTROL OR UNCONSOLIDATED FORMATIONS AND HIGHLY PERMEABLE THIEF ZONES CAN BE ACHIEVED.

TREATMENT :

ULTRA SEAL ( PLUS ) IS NORMALLY RECOMMENDED IN CONCENTRATION OF 20 - 40 PPB, MIXED IN BATCHES OF 100 TO 200 BBLS AND SPOTTED ACROSS THE LOSS ZONE IMMEDIATELY AS SIGNS OF LOSSES OCCUR.
THIS PRODUCT SOME TIMES CONSIDERING PRETREATING THE CIRCULATING SYSTEM WITH 15-20 PPB ULTRA SEAL (PLUS) AND BYPASSING THE SHALE SHAKERS, THIS METHODS HAS BEEN VERY SUCCESSFUL FOR SHELL IN
CANADA.

PRODUCT DATA SHEET
ULTRA SEAL-PLUS®

DESCRIPTION: A proprietary blend of fibrous, granular and flake materials designed specifically for massive loss of circulation. This product was formulated to expand the existing positive qualities of the ULTRA SEAL9 product line.

USES: Severe Loss Circulation Control

FEATURES: ULTRA SEAL-PLUS ® is a blend of ULTRA SEAL-XP ®,
ULTRA SEAL-C ® and additional larger, proprietary sealing agents. This blend expands the superior range of particle sizes that are consistent with the existing product line.
This large particle array is beneficial in establishing a stronger initial bridge across the thief zone, thus allowing time for the specialized fibers found in me UL TRA SEAL-XT ® and UL TRA SEAL-C ® to fill any remaining micro-fractures that may be present.
By the inclusion of these larger particles, effective control of rigid type fractures, jugular or unconsolidated formations and highly permeable thief zones can be achieved.

TREATMENT: ULTRA SEAL-PLUS ® is normally recommended in concentrations of 20 to 40 ppb mixed in batches of 100 to 200 bbls and spotted across the loss zone.

PACKAGING: 40 pound net in multi-wall paper bags.

SHELL IS DRILLING WITH THE ABOVE CONCENTRATION SYSTEM WIDE TO PREVENT LOSS CIRCULATION THROUGH CONGLOMERATE AND RUBBLE ZONE OFFSET WELLS WERE DRILLED USING 7 - 10 CEMENT PLUGS TO CONTROL LOSSES, CURRENTLY WELLS ARE BEING DRILLED USING ULTRA SEAL ( PLUS ) WITH 1 - 3 BBLS / HOUR SEEPAGE AND THREE DAYS SAVING OF BIG TIME.

DEAR SIR,
AT CONCENTRATION IS PPB, ULTRA SEAL ( PLUS ) AND AT 10 PPB OF ULTRA SEAL ( C ) TO LOAD THE SYSTEMS IS REQUIRED SOME TIMES DEPEND ON THE WELL CONDITION THIS FORMULATION HAS RECENTLY BEEN SUCCESSFULLY USED BY SHELL OIL IN WESTERNS ALBERTA - CANADA TO DRILL SURFACE HOLE IN AN AREA KNOWN TO BE VERY PROBLEMATIC WITH REGARDS TO SEVEER LOSSES OF MUD TO A RUBBLE ZONE. THE ZONE WAS DESCRIBED TO US AS BEING A MIXTURE OF DIFFERENT SIZE ROCKS RANGING IN SIZE FROM BOULDERS DOWN TO LARGE PEA GRAVEL WHICH IS DISPERSED A LONG FAULT LINE.
THIS ZONE HAS REQUIRED IN THE PAST A MINIMUM OF SEVEN (7) CEMENT PLUGS AND SOME TIMES LOSING OF THE BHA TO GET THROUGH IT AND FAILURES OF SETTING 13 3/8" CSG.
ULTRA SEAL WAS USED AS DESCRIBED ABOVE AND THE ZONE WAS DRILLED IN RECORD TIME WITH NO PROBLEMS AND MINIMIZED MUD LOSS.

MIXING AND PUMPING OPERATION :-
1) MIX THE ULTRA SEAL ( PLUS ) FROM 2 - 3 SX / MINUTE.
2) KEEP THE SYSTEM IN ACTIVE POSITION.
3) BEFORE PUMPING THE PILL, REMOVE THE PUMP STRAINER AND THE SURFACE, i.e. ( MWD ) STRAINER.
4) PUMPING RATE MUST BE FROM 2 - 3 BBL / MINUTE ABOVE THE THIEF ZONE.
5) LEAVE THE PILL FOR (3) HOURS THEM START LOW CIRCULATION PUMPING UNTIL YOU GET FULL RETURN.
6) DUE TO THE LARGE PARTICLE SIZE OF THE ULTRA SEAL (PLUS) IT WOULD BE NECESSARY TO BYPASS THE SOLIDS CONTROL EQUIPMENT WHILE IT IS BEING USED.
7) PPB ULTRA SEAL ( PLUS ) WILL PASS THROUGH 8 1/2" BIT WITH A JET SIZE OF 13.
