AN EDITORIAL - CEMENT EVALUATION LOGGING IS VERY POLITICAL - THE CEMENT EVALUATION LOG REFLECTS THE QUALITY OF THE WELL DRILLED AND CEMENTED AND IS A DIRECT REFLECTION ON THE DRILLING DEPARTMENT, WHICH MAKES THE CEMENT EVALUATION LOGGING VERY POLITICAL AND CONTROVERSIAL. CONSEQUENTLY, THE DRILLING DEPARTMENT SEEMS TO HAVE INSULATED ITSELF FROM BOND LOG RESULTS, AND INPUTS OF CEMENT PLACEMENT AND MEASURED IN PLACE CEMENT CURING, HELPED BY MORE COMPLEX BOND LOG PRESENTATIONS. THE DRILLING DEPARTMENT NEEDS A LOGGING COMPANY AND A CEMENTING COMPANY WITH - THE VOCABULARY, KNOWLEDGE, UNDERSTANDING, AND CONFIDENCE TO PRESENT AND COMMUNICATE, CEMENT PLACEMENT ANALYSIS AND MEASURED IN PLACE CEMENT CURING AT THE TIME THE LOG WAS RUN FOR ZONE ISOLATION EVALUATION THRU THE WELL'S CRITICAL INTERVALS. A PROVEN, VISUAL, SIMPLE, CONSISTENT LOG INTERPRETATION PRESENTATION THAT EVERYONE IN THE ROOM CAN COMFORTABLY UNDERSTAND - CEMENT ZONE ISOLATION EVALUATION AND CEMENT PLACEMENT ANALYSIS AND MEASURED IN PLACE CEMENT CURING - IS NEEDED. A PRESENTATION THAT LOOKS TO LEARN FROM THE CURRENT WELL’S CEMENT JOB, WHILE LOOKING TOWARD THE NEXT WELL IN THIS AREA. THIS HAS NEVER BEEN MORE EVIDENT THAN NOW!!!!! DRILLING NEEDS TO BE MORE INVOLVED IN, AND AWARE OF, CEMENT EVALUATION AND NEEDS THESE INPUTS – CEMENT PLACEMENT ANALYSIS AND MEASURED IN PLACE CEMENT CURING AT THE TIME THE BOND LOG WAS RUN – THE CHL AND BE BETTER EQUIPPED TO MAKE CRITICAL DECISIONS AT CRITICAL TIMES. FOR A TYPICAL DEEP WATER WELL, CHANGING FROM – A 7” LINER COMPLETION WITH A 9 5/8” TO 7” TIE BACK STRING TO A BETTER CASING STRING DESIGN - A CONTINUOUS 9 5/8” TO 7” PRODUCTION STRING In the approval meetings for changing the casing string design, for an improved final continuous casing string of 9 5/8” and 7” for the well’s production string, was in place cement curing discussed for the complex cementing recipe for the hundreds of feet of high perm, high temperature, geo-pressured production zone?

In all the other previously completed wells, the 7” liner complex cementing recipe was in place 78 to 96 hours before ask to control the differential pressure from reducing the mud weight from 18 #/gal to 12.5 #/gal completion fluid. On all the previous completed wells after cementing the 7” liner thru the production zone, the rig operations to complete the well, created the in place cement curing time that was required and the importance of in place cement curing for the complex production zone cement recipe was lost – * Set the liner hanger and clean up the cement job at the liner top and come out of the well from 17,000 ft – 10 to 12 hours * Trip into the well to 17,000 ft to check and dress the 7” liner top preparing for the tie back casing tie in and trip back out from 17,000 ft – 20 to 24 hours * Run the cement evaluation log after 30 to 36 hours of cement curing time – 8 to 10 hours * Rig up and run the 11,500 foot 9 5/8” and 7” tie back casing string to the top of the 7” liner at 17,000 ft and tie into the 7" liner top - 36 to 40 hours * Hang off the 9 5/8” casing in the well head casing spool and come out of the well from 5,500 ft – 4 to 6 hours Again, the complex cement recipe for the 7” liner production zone on the previous wells had 78 to 96 hours of in place cement curing time with 18 #/gal mud in the well, created by rig operations to complete the well, allowing the cement to cure enough to control the differential pressure from reducing the mud weight from 18 #/gal to 12.5 #/gal completion fluid. With the improved production casing design, all those rig operations were eliminated, and the production zone’s cement job in place cement curing time with 18#/gal mud in the well was greatly reduced. Without the knowledge and understanding of cement placement and in place cement curing for the complex cement recipe for the 7” liner production zone on the previous wells, Drilling and everyone must have assumed, that when the casing was run, the cement job was complete, and the cement was set, and the well was secure. Apparently because of this sinse of security, the change out of the 18 #/gal drilling mud to the 12.5 #/gal completion fluid was started, with the production zone’s cement job in place cement curing time with 18#/gal mud in the well of 10 to 12 hours, without the rig being on high alert, and without a rehearsed well security testing procedure in place. What was the pumping time for the cement recipe used? Who made the decision to send the Schlumberger Crew in while the continuous casing string of 9 5/8” and 7” for the well’s production string was being run the day before the blowout? The Schlumberger Crew had been called out to run a cement evaluation log thru the 7” production zone. Was it the recommendation and input of the Schlumberger Engineer at the Rig, because he knew to attempt to run a cement evaluation log over the complex 18 lb/gal cementing recipe for the hundreds of feet of high perm, high temperature, geo-pressured 7” production zone with only 10 to 12 hours of in place cement curing, the cement could not have developed enough cement compressive strength for the cement evaluation log to correctly evaluate in place cement curing and zone isolation thru the critical zone interval for the well’s 7” production zone, and logging 18 lb/gal green cement would be a waste of time? With the knowledge and understanding of cement placement and in place cement curing for the complex cement recipe for the 7” liner production zone on the previous wells, Drilling has lots of options to change out the mud and secure the well using the better casing design, the continuous casing string of 9 5/8” and 7” for the well’s production string. Not using the knowledge and understanding of cement placement and in place cement curing for the complex cement recipe for the 7” liner production zone on the previous wells, and planning for sufficient in place cement curing time, was much more significant, than only running 6 of the proposed 22 casing centerlizers.

AN EDITORIAL - RESPONSE TO THE QUESTION – In the approval meetings for changing the casing string design, for an improved final continuous casing string of 9 5/8” and 7” for the well’s production string, was in place cement curing discussed for the complex cementing recipe for the hundreds of feet of high perm, high temperature, geo-pressured production zone? ANSWER – NO In all my years working in the Oil Industry and being a part of casing design approval meetings, in place cement curing has never been part of the approval agenda. Even the Industry Experts at the previous trial did not indicate in place cement curing to be a concern. Had we been aware that in place cement curing for the complex cementing recipe necessary for the hundreds of feet of high perm, high temperature, geo-pressure production zone would require 30 to 36 hours to start generating enough cement compressive strength to start controlling the production zone, the completion procedure for securing the well would have been different. Such as, the top of the continuous 9 5/8” and 7” production casing string would be hung off in the 9 5/8” casing spool in the well head and secured and tested which is a part of the well head structure, a traditional industry standard. The well’s annular area and casing back side with 18 #/gal drilling mud and cement would be secure from up flow. To secure the bottom of the production string guide shoe and float collar, with the well secure with 18 #/gal drilling mud still in the well, go in the well with a 7” squeeze retainer to check the security of the guide shoe and float collar plus set the cement retainer just above the 7" float collar for additional well security from in flow at the well’s TD from the production zone. Then, with the top of the continuous 9 5/8” and 7” production casing string securely hung off in the well head and the bottom of the production casing string guide shoe and float collar secured with the addition of a 7” cement retainer set just above the 7" float collar, the casing string should be secure. With the rig on high alert, and with a rehearsed well security testing procedure, change out the 18 #/gal drilling mud with the 12.5 #/gal completion fluid and finish completing the well. QUESTION - Why were you not aware of the importance of in place cement curing for the production zone complex cementing recipe necessary for the hundreds of feet of high perm, high temperature, geo-pressure production zone? ANSWER – The importance of in place cement curing for this complex cementing recipe on all the previous deep water wells, which were 7” liner production strings, was lost because of all the necessary well completion procedures following cementing the liner which gave the impression that in place cement curing was not a concern, such as - * Set the liner hanger and clean up the cement job at the liner top and come out of the well from 17,000 ft – * Trip into the well to 17,000 ft to check and dress the 7” liner top preparing for the tie back casing tie in and trip back out from 17,000 ft * Run the cement evaluation log after 30 to 36 hours of cement curing time * Rig up and run the 11,500 foot 9 5/8” and 7” tie back casing string to the top of the 7” liner at 17,000 ft and tie into the 7" liner top * Hang off the 9 5/8” casing in the well head casing spool and come out of the well from 5,500 ft This gave the cement 78 to 96 hours of curing time with 18 #/gal drilling mud before the cement was ask to control the production zone differential pressure from reducing the mud weight from 18 #/gal to 12.5 #/gal completion fluid. Again, on all the previous completed wells, after cementing the 7” liner thru the production zone, the rig operations necessary to finish completing the well, created the in place cement curing time that was required for well security and in place cement curing concerns was not an issue. QUESTION - What would be your recommendation of all future deep water completions? ANSWER – The continuous 9 5/8” and 7” production casing string is a good casing design for continuous pipe from the well head to the well’s TD, top to bottom, covering all the liner sections needed to drill the well to these depths to insure casing integrity for these complex, high production rate very expensive wells. But the awareness of cement placement and in place cement curing for the complex cementing recipe necessary for the hundreds of feet of high perm, high temperature, geo-pressure production zones, needs to be an integral part of the planning for the safe completion of the future wells. AS A SOLUTION - The industry needs to be aware of and have available cement placement analysis and measured in place cement curing as part of the industry’s cement evaluation package. The CHL is existing interpretation technology with a visual, simple, consistent presentation with the CHL Trace for cement zone isolation evaluation and cement placement analysis and the CHL Heading having measured in place cement curing in an easy to understand format. The exiting cement evaluation technology evaluates what happens before and after cement placement, but none of the existing cement evaluation Logging packages technology presents and evaluates and measures the in place cement curing process. This technology has not been routinely a part of the available cement evaluation Logging package for the industry, even though it is a critical part of the cement evaluation process to insure the success of the cement job. The addition of cement placement analysis and measured in place cement curing as a routine part of the of the cement evaluation Logging package in a proven, visual, simple, consistent log interpretation presentation so everyone in the room can comfortably understand - cement zone isolation evaluation and cement placement analysis and measured in place cement curing - would insure that in place cement curing would be a concern and a part of the completion planning. QUESTION - IS THIS A REASONABLE ANSWER TO THE QUESTION?

AN EDITORIAL - The Cementing Companies main focus is to help design and laboratory test each cement recipes, sell cement and the necessary designed additives for the unique cementing recipe designed for each well, furnish the personnel and the specialized equipment to deliver and mix and pump the cement job at the well sight and does not include in place cement curing analysis. The Logging Companies cement evaluation package main focus, as directed by the industry, is toward the up or down cement evaluation meeting immediately after running the well’s cement evaluation log to determine, with the rig waiting, if the cement job is satisfactory or unsatisfactory for zone isolation thru the critical intervals for the well’s production zones which determines the sequence of the rest of the completion steps to continue finishing the completion of the well. This focus does not normally include measured in place cement curing analysis. The importance of having the knowledge and understanding of in place cement curing, most of the time, is not a critical concern, but knowing that sometimes it is, changes everything.
