CHL INTRODUCTION -
WHAT ARE THE RANGE OF VALUES THAT DEFINE THE SUCCESS OF YOUR CEMENT JOB?
A TWO MILLIVOLT READING ALWAYS INDICATES A GOOD CEMENT JOB, BUT SOMETIMES A
TEN TO FIFTEEN MILLIVOLT READING CAN BE A GOOD CEMENT JOB ALSO.
USING THE 3 FT AMPLITUDE SIGNAL, THE CHL IDENTIFIES THE 100% CEMENT READING FOR YOUR
CASING SIZE, CASING THICKNESS, AND CEMENT COMPRESSIVE STRENGTH AND COUPLES IT WITH
THE INTERPRETATION CUTOFF LIMIT FOR POSSIBLE 100% CEMENT, CRYSTALLINE CEMENT,
FOR A CONSISTENT INTERPRETATION IN A TWENTY LINE DISPLAY WITH SHADING FROM BLACK
TO GREY TO WHITE.
THE OVERALL CHL DISPLAY IS ALSO DESIGNED TO GIVE INSIGHT INTO THE CEMENT’S JOB
DISPLACEMENT PATTERN -
1. IS THE CASING CENTER WITH UNIFORM DISPLACEMENT,
2. IS THE CASING EXCENTERED WITH UNIFORM DISPLACEMENT ON THE HIGH SIDE,
3. IS THE CEMENTING COLUMN ROTATING AND SPIRALING UP THE HOLE?
FROM THE CHL SHADING, IF A CHANNEL OF NON-CEMENT EXIST, USING THE HYDRAULIC DISPLACEMENT
PATTERN, DOES THE CHANNEL HAVE CONTINUITY TO A ZONE OF UNWANTED PERMEABILITY?
THE CHL PRESENTATION AND THE HEADING’S GOAL IS TO GIVE INSIGHT INTO THE PRESENT CEMENT
JOB AND ZONE ISOLATION ON THIS WELL WITH A LOOK TOWARD THE NEXT WELL IN THIS AREA.
THE CHL PROGRAM IS CURRENTLY WRITTEN IN A MICROSOFT FORMAT ACCESSIBLE ON THE
INTERNET AT www.addchl.com. THE CHL IS ADDED TO YOUR CEMENT EVALUATION PACKAGE
AFTER THE LOG IS RUN. WITH THE LAS FILE OF THE MAIN LOG SECTION WITH DEPTH AND
THE 3 FT AMPLITUDE DATA AND WITH THE PDF OR PBM FILE OF THE SAME MAIN LOG SECTION,
LOG ON TO THE CHL SITE AND ADD THE CHL. IT TAKES 10 TO 15 MINUTES TO RUN THE
CHL PROGRAM AND HAVE A CHL PDF OR A CHL PBM FILE READY TO PRINT OR E-MAIL.
DETAILS AND APPLICATIONS OF THE CHL ARE AVAILABLE IN THE ATTACHED POWER POINT

RECIPE PERFORM AS DESIGNED AND INTENDED WHEN PUMPED UNDER
THE WELL’S FLOWING HYDRAULICS CONDITIONS FOR CEMENT PLACEMENT,
AND DID THE IN PLACE CEMENT SLURRY CURE AS DESIGNED IN THE
ENVIRONMENT OF THIS WELL AND IN THIS AREA?
THE CHL INTERPRETATION APPROACH INCLUDES AN IN PLACE CEMENT

THE OBLECTIVE OF THE CHL IS TO ASSIST THE CEMENT JOB DESIGNER
EVALUATE THE CEMENT JOB DESIGN ON THE WELL LOGGED LOOKING AT
THE CEMENT JOB DESIGN FOR THE NEXT WELL IN THE AREA.
LOOKING AT WELLS WITH QUESTIONABLE PRODUCTION
---- START YOUR EVALUATION HERE!!!
ON WELLS WITH QUESTIONABLE PRODUCTION, WHAT WOULD BE THE FLUID FLOW MECHANICS
OF A PRODUCING CHANNEL??
1. CHANNEL WIDTH
2. CHANNEL LENGTH AND CONFIGURATION
3. CHANNEL CONTINUITY
4. PRESSURE DIFFERENTIAL AVAILABLE FOR FLOW
5. CHANNEL FLOW RATE
START THE RESEARCH BY REFRESHING THE CEMENT EVALUATION PACKAGE FOR THE WELL USING
THE CHL PROGRAM FOR THE –
1. CHANNEL WIDTH FROM THE CHL
2. CHANNEL LENGTH AND CONFIGURATION FROM THE CHL
3. CHANNEL CONTINUITY FROM THE CHL CEMENT PLACEMENT HYDRAULICS UNDERSTANDING
THEN ADD THE DIFFERENTIAL PRESSURE AND THE FLOW RATE TO ESTABLISH IF THE FLUID
FLOW MECHANICS CONDITIONS ARE SUITABLE FOR CHANNEL FLOW.
E-MAIL THE FOLLOWING TO wwheelis@cox.net
