EMDC Drilling Standard Operations Manual for Jack-Up/Platform/Barge Drilling
To: ExxonMobil Drilling Employees
The enclosed manual is the First Edition of our EMDC Drilling Standard Operations Manual for Jack-Up/Platform/Barge Drilling. This manual replaces the Transition Version 1 manual datedOctober 1999. Many changes and upgrades have been made to this manual based oncomments from the Drill Teams and Drilling Support Groups. The preface of the manual
describes how the manual will be used in our operations. In short, the manual:1) provides guidelines for conducting drilling operations using jack-up, platform and barge
rigs,2) is used in conjunction with specific well programs and other procedural manuals,
including OIMS and SMP, to provide the basic framework and principles required for planning and conducting drilling operations, and
3) shall be reviewed and understood by all drilling personnel.
Important to note is that signi f icant changes (any change that increases health, safety,public, environmental or financial risk) from the manual need the consent of the OperationsSuperintendent and/or Field Drilling Manager. Also, the guidelines in the manual must beappropriately interfaced with those established by the Drilling Contractor and conflictsaddressed by the Operations Superintendent.
Special appendices are included in each section of the manual for drill teams to customize themanual for their operating area. The tabs for these appendices are labeled “G” for generalinformation and forms/documents that are used company wide and “S” for specific informationand forms/documents that are unique to individual drill teams.
We appreciate the time and effort by the Drill Teams and Drilling Support Groups in reviewingand commenting on the draft manual. Over 150 comments were received with about 90%adopted in the new manual. The remaining comments referred to requests to include localpractices, sections in the draft manual that were removed, general comments with nosuggested changes, items not applicable to this manual, and a very few number of items notagreed to. In order to close the loop, Drill Teams that suggested changes not agreed to willreceive feedback.
This manual will be revised and upgraded in accordance with the revision process in theOIMS manual. In general, this process will involve review of comments received from the DrillTeams, annual review of MOCs, and reviews at periodic intervals.
Please take the time to review this manual and understand the guidelines contained within.

PREFACE
DRILLING OPERATIONS MANUAL – JACK-UP/PLATFORM/BARGE RIG DRILLING 1 of 1
First Edition - May, 2003
The ExxonMobil Development Company, Standard Operations Manual for Jack-Up/Platform/Barge
Drilling has been prepared to provide guidelines for conducting drilling operations using jack-up, platform
and barge rigs in ExxonMobil Drilling's realm of activities.
This manual, used in conjunction with well-specific Drilling and Completion Programs and other procedural
manuals, including the Drilling OIMS Manual and the Safety Management Program Manual, will provide
the basic framework and principles required for the Operations Supervisors and Drilling Engineers for
planning and conducting drilling operations. Because of the numerous possible variables and conditions
which can occur, this manual cannot replace the knowledge and good judgment of key drilling personnel on
the drilling rig or in the office. The guidelines contained within this manual are the logical sequence of steps
necessary to efficiently conduct drilling operations in a safe and environmentally sound manner on a global
scale while complying with applicable regulatory requirements. Although many of the references to U.S.
laws and regulations were removed from the previous version due to the global intent of this manual, some
remain as examples and may be valuable for international operations.
The guidelines contained herein shall be reviewed and understood by all involved drilling personnel. In
accordance with the OIMS "Management of Change" element, significant changes (any change that
increases health, safety, public, environmental or financial risk) from these guidelines are not to be
undertaken without the express consent of the Operations Superintendent and/or Field Drilling Manager.
The guidelines contained in this manual shall also be appropriately interfaced with those established by the
Drilling Contractor and contained in the Drilling Contractor's operations manuals. Identified procedural
conflicts shall be addressed by the Operations Superintendent and any resulting resolutions shall be
provided to the Operations Supervisors.
Special appendices are included in each section of the manual for drill teams to customize the manual for
their operating area. The tabs for these appendices are labeled “G” for general information and
forms/documents that are used company wide and “S” for specific information and forms/documents that
are unique to individual drill teams.
The manual shall be kept current by including recommended improvements/changes in accordance with the
change process described in the EMDC Drilling OIMS Manual. In general, this process will involve review
of comments received from the Drill Teams, annual review of MOCs, and reviews at periodic intervals.
This process is critical in keeping Drilling abreast of new ideas, advancing technology and regulatory
changes.
This manual was prepared in an attempt to combine the best practices of our drill teams into one manual.
Although it does contain a good bit of information from multiple sources, it does not contain all the
information needed to drill and complete drill wells in all situations. Good sound judgement should always
be exercised in any task and should never be discarded just to follow an outlined step in any process or
procedure

1.2 ORGANIZATION
EMDC - Drilling Organization
EMDC Drilling is responsible for ExxonMobil's world-wide production and exploration drilling activities.
The Drilling Organization is responsible for the contracting of services and materials suppliers, the planningand preparation of drilling engineering work, and the direct supervision of drilling operations. The Drilling
Organization shall prepare guidelines and procedures, as necessary, so that operations are conducted in a
safe and environmentally sound manner. These responsibilities will be met by the following personnel:
• Manager, Drilling
• Drilling Operations Manager
• Procurement Manager
• Drilling Technology Manager
• Field Drilling Manager

•
Engineering Manager • Operations Supervisor
• Supervising Engineer
• Drilling Engineer
• Drilling Materials & Services Supervisor
• Procurement Services Advisor
• SHE Manager, Drilling
• Environmental Coordinator, Drilling
Drilling Contractor and Other Critical Third Party Service Contractors
The Drilling Contractor is an independent contractor who will execute the drilling program to thesatisfaction of the Operations Supervisor on location. The drilling contractor is also responsible for
operating and maintaining the drilling rig in safe working condition and in full compliance with EMDC
technical specifications and local regulatory requirements, including those requirements as specified in the
drilling contract.
Other critical third party service contractors are independent contractors that will assist in executing the
drilling program. These contractors are responsible for operating and maintaining their equipment in full
compliance with EMDC technical specifications and/or contract requirements, and local regulatory
requirements.
The drilling contractor and other critical third party service contractors provide services where inadequate
performance could result in a Level 1, 2, or 3 incident (OIMS Element 9). These contractors must meet
or exceed EMDC requirements in the area for which the contract is issued. This includes the following:
• Safety, Health, and Environmental Policy Statement
• Drug and Alcohol Policy
• Contractor Safety Program

First Edition - May, 2003
• Technical Equipment Documentation
• Work Permit System
• Hazardous Material Handling/Storage Procedures
• Procedure to Control Equipment/Safety Policy Changes
Service Companies/Third Party Services
Service companies/third party service contractors are independent contractors who will assist in executing
the drilling program to the satisfaction of the Operations Supervisor on the drilling rig. These contractors
are also responsible for operating and maintaining their equipment in full compliance with EMDC technical
specifications and local regulatory requirements, including those as specified in the various contracts.
1.3 EMDC- DRILLING REPORTS
Critical drilling operations information and relevant aspects of the daily drilling activities will be documented
in the standard reports developed by EMDC and its contractors. This manual describes the preparation
and distribution of these reports.
Daily Drilling Report
The Operations Supervisor will record drilling activities on the DRS and transmit it, usually via the LAN or
telephone line (modem), to the Drilling Information Management Center (DIMC) each morning.
The Daily Drilling Report will cover a 24 hour period with the current day's drilling activities.
Minimizing drilling cost per foot and achieving an overall increase in the efficiency of a drilling operation
requires that Management, the Operations Superintendent, and Engineering receive accurate, factual,
complete reports from the rig Operations Supervisor on a daily basis. Effective management control of the
drilling operation cannot be effected without input from the entire drilling organization, and the daily drilling
report is the base document from which most information is drawn. The following are guidelines on some
aspects of the Daily Drilling Report:
• Drilling operation events should be time separated to correspond with EMDC rig-time distribution codes
(not IADC). The DRS manual contains a guide on the coding of operations.
• Depth of the well is determined by steel line measurement of the drill string.
• There should be reasonable agreement between the DDR and the IADC report.
• A better report will result if each Operations Supervisor writes the operations summary for his/her tour.
• Do not report opinions or guesses unless they are so identified. If an opinion is reported as fact, the rig
supervisor will know this, but the office staff may not.
• Use only standard abbreviations. Do not make up abbreviations.
• Electric logging: specify logs run, depth interval logged, bottom hole temperature, and tight hole depth.
• Circulation: specify why the mud is being circulated, and circulation rate/ pipe rotation if any.

DRILLING OPERATIONS MANUAL - JACK-UP/PLATFORM/BARGE RIG DRILLING 4 of 10
First Edition - May, 2003
Daily Cost Report
The Operations Supervisor should complete the DRS Daily Cost Report and transmit it to the DIMC each
morning.
The Daily Cost Report should capture all substantial drilling costs including services utilized, rental
equipment, and consumed materials. Where exact costs are not known, reasonable estimates should bemade and included in the Daily Cost Report. Some contractor costs will not be known exactly until the
end of a month. The rig should not attempt to estimate what the discounted charge will be; the rig is to
enter the ticket charge on the cost screen. The Drilling Engineer is responsible for monitoring discounted
materials and services costs and communicating any adjustments to the Operations Supervisor for
modification of cost sheets.
It is the Drilling Engineer's responsibility to include the cost of all materials and services in appropriate
procedures for Operations Supervisor use in completing the Daily Cost Report. The Drilling Engineer is
also to provide initial fixed costs to Operations Supervisor and to check the entries for errors or omissions.
ATF Bomb Threat Checklist
Operations Supervisors need to be prepared to respond effectively should they receive a bomb threat over
the telephone. It is very important to take the caller seriously. Ask the person to repeat the message.
Record every word spoken by the person. Complete the bomb threat checklist and transmit to the
Operations Superintendent. Reference OIMS manual (10-5) for further information.
Casing Tally Report
The Casing Tally Report should be prepared for every casing string run. A copy of the report will be kept
on the drilling vessel for reference during logging, production testing, completion, plug and abandonment
operations, etc.
The Operations Supervisor is responsible for completing the casing run tally report and forwarding it to the
Drilling Engineer after each casing string is run. While it is not necessary to transmit the off-load tally from
the rig, it is necessary to create a DRS off-load tally to be able to complete the casing description part of
the DRS "as run" tally. OIMS requires a DRS casing tally report where possible.
Environmental Performance Indicators (EPI) Report
At the end of every well, the Drilling Engineer and EMDC Domestic Regulatory Technician will complete
the Environmental Performance Indicators (EPI) Report for inclusion in the Final Well Report. This form
contains four sections; Well Information, Emissions Data, Environmental Regulatory Compliance Data, andWaste Data.
Drilling Reporting System (DRS)
When the DRS system is in place, the following DRS reports will be maintained and transmitted from the
rig daily or when pertinent, 1) Daily Drilling Report, 2) Casing Report, 3) Cementing Report, 4) Lithology,

Weather, 13) Well Test, 14) Stratigrophy.
Equipment Failure Report
An equipment failure report will be prepared to document equipment failures which result in significant
economic impact or failures which could have safety implications. The equipment failure report shouldadequately describe the nature of the failure, identify the cause of the failure, document the associated
downtime due to the failure, and recommend ways to prevent the failure from occurring in the future.
The Operations Supervisor is responsible for preparing the report and forwarding it to the Operations
Superintendent. Engineering will review the report to determine if further analysis or action is required.
Hand-Over Notes
Hand-over notes will be prepared by the Operations Superintendents (when working on a rotational
schedule) and Operations Supervisors prior to their respective crew changes. The purpose of these notes
is to document all situations and/or activities that will require follow-up by the relieving personnel, as well asto address significant operational events that took place during the hitch.
Material Transfer/Cargo Manifest
A material transfer/cargo manifest should be prepared for all material shipments to and from the drilling rig.
Manifests should be prepared by the Base Manager/Materials Coordinator for all to-rig shipments and by
the drilling rig's storekeeper (if on contract) for all from-rig shipments.
The cargo manifest should list all materials transferred, giving quantity, description, weight, and the
container number in which it is stored.
Material transfers are prepared for EMDC material and will usually list the commodity number. Hazardous
material should be identified on the manifest. Under no circumstances should used casing thread protectors
be sent to the United States in a container unless all thread compound is removed. There will be venture
specific materials procedures.
