SUMMARY
WHAT DOES WATER
PRODUCTION COST??
25,263,000,000 BBLS OF WATER PRODUCED
IN UNITED STATES- 2000
AVERAGE WATER CUT 94% per WELL
$5 BILLION COST TO THE INDUSTRY
MORE IS SPENT ON PRODUCED WATER
THAN ALL OTHER MAJOR SERVICES
COMBINED

CAN BE USED IN PLACE OF STANDARD CEMENT
SQUEEZES FOR VARIOUS APPLICATIONS
HIGH TEMPERATURE POLYMER
ADVANTAGES OF HTP SLURRY:
NO NEED FOR ZONAL ISOLATION AS WITH STANDARD
CEMENT OPERATIONS
SLURRY IS BULLHEADED INTO ALL PERFORATIONS
SHALLOW PENETRATION OF THE FILTRATE ALLOWS FOR
RE-PERFORATION IN THE HYDROCARBON ZONE
HTP SLURRY LEFT IN THE HOLE DOES NOT HAVE TO BE
DRILLED OUT, AND CAN EASILY BE JETTED OUT WITH
COILED TUBING.
RIDGID SETTING FLUID
FORMULATION OF INORGANIC NON TOXIC POWDERS AND
FLUIDS MIXED IN A BRINE SOLUTION
USED TO PERFORM CHEMICAL ISOLATIONS/SHUT OFFS IN
VERTICAL AND HORIZONTAL WELLBORES
CHARACTERISED BY A CONTROLLED RIGHT ANGLE SET
FOLLOWED BY RAPID STRENGTH DEVELOPMENT.
ONCE SET PRODUCT HAS MECHANICAL CHARACTERISTICS
SIMILAR TO CEMENT BUT IT IS NOT A CEMENT.
RIDGID SETTING FLUID
ZERO SHRINKAGE.
ZERO STATIC GEL GENERATION.
WILL NOT INVADE FORMATION.
100% ACID SOLUBLE WITH 15% HCL.
TREATMENTS TYPICALLY 25 BBLS OR LESS.
RIDGID SETTING FLUID
IMMISCIBLE IN OIL.
TOLERATES UP TO 50% CONTAMINATION.
TYPICALLY 5 MICRON MEDIAN PARTICAL SIZE.
VARIABLE VISCOSITY FROM 18 CP TO 100 CP.
RIDGID SETTING FLUID
NEAR WELLBORE PHENOMENON
EXOTHERMIC REACTION TIME AND TEMPERATURE

HOW IS AN RPM DIVERTOR USED?
BULLHEAD TREATMENT: ALTERNATING STAGES OF RPM FLUID
AND ACID
NO DAMAGE TO HYDROCARBON BEARING ZONES
ENHANCES ZONAL COVERAGE BY DIVERTING ACID AWAY FROM
WATER BEARING ZONES
DOES NOT REQUIRE VISCOSITY TO AID IN DIVERSION
SIMPLE AND EASY TO USE:
NO ZONAL ISOLATION NEEDED.
NO SPECIAL PLACEMENT TECHNIQUES REQUIRED.
RPM FRAC SERVICE
SOMETIMES FRACTURE STIMULATION RESULTS IN
MORE THAN HYDROCABON PRODUCTION?
RPM FRAC SERVICE
CONFORMANCE WHILE FRACTURING:
LIMITS RISK ASSOCIATED WITH FRACTURING NEAR HIGH WATER
SATURATION
REDUCES PERMEABILITY TO WATER
REQUIRES NO SPECIAL PLACEMENT TECHNIQUES
A SIMPLIE LIQUID ADDITIVE THAT CAN BE INCLUDED AS PREPAD
OR ADDED TO THE ENTIRE TREATMENT
RPM FRAC SERVICE
COMPATIBLE WITH MOST EXISTING FRAC

SUMMARY
EXCESSIVE WATER PRODUCTION CONTINUES TO
COST THE INDUSTRY BILLIONS OF DOLLARS A
YEAR
SUCCESSFUL TREATMENTS CAN BE PUMPED
SOFTWARE FOR DESIGN AND APPLICATIONS ARE
AVALIABLE
NEW PRODUCTS HAVE BEEN DEVELOPED FOR
