1 General Information

The well will be drilled by the Rowan Viking drilling rig. Wireline logging will be carried out in the 9 5/8in and 7in. casing only.

1.1 Objectives, Requirements and Recommendations for Wireline Logging

1.1.1 Wireline Logging Objectives

To carry out all actions without harm to personnel or the environment.

Run Schlumberger Isolation scanner as CIS to identify

Good casing cement outside the 9 5/8in casing

Run INTeX SBT logs to identify:

Good casing cement outside the 9 5/8in casing and in liner

Run 60 arm Multi Finger Caliper to identify:

Casing wear in packer setting area in the 9 5/8in casing, and in the 7in liner

Verify Production Packer setting depth in 7in liner with good cement bond and no casing wear

Run Reservoir Saturation Tool (RPM).

Run RPM tool in 7in liner to provide a base line Saturation Log

1.1.2 General Requirements for Wireline Logging

All equipment preparation and mobilization to be in compliance with Baker Hughes policies and procedures as defined in BHOS and WS Managing the Job Cycle.

All Wireline cables will be seasoned.

Upon completion of drilling and casing/cementing operations and prior to commencement of wireline operations, survey data, casing details, well fluid data and cement information and other data as required should be delivered to the wireline unit by the Wellsite geologist. The reference log for depth correlation, GR or Casing Tally should be provided by Lundin.

A summary of the logging suite identifying each tool in the string in the correct sequence including all auxiliary tools, knuckles, centralizers, stand offs etc will be provided as a tool diagram before deployment.

Tool sketch shall be provided in all log plots.

All corrections and remarks on the logging runs shall be provided.

A time breakdown of logging operations shall be maintained by the wireline lead Field Service Engineer with all details of any lost time recorded on the time breakdown and the duration agreed with the Lundin representative.

A written description of all tool problems encountered will be presented to the Lundin representative offshore.

In the event of tool failure, initial failure report and subsequent follow-up will be provided by Baker Hughes onshore using the First Alert problem resolution system.

A main and repeat pass have to be logged for all services where applicable. Both main and repeat passes must be presented on the log




The Lundin wireline supervisor will maintain an independent time breakdown with a written description of the logging operations for each log run. This shall include the string length and the logging speed used and an appraisal of the service quality of all personnel and equipment used.

1.1.3 Recommendations to Follow During Logging

The raw curves on the log presentation should be free from spikes.

Any decision to re-log a zone due to poor/no data will come from the Lundin Wellsite geologist following a recommendation from the logging engineer.

Repeat sections will be performed after the main pass. The Wellsite geologist and logging engineer will decide on a repeat section 60m or longer, based on section of interest seen in the main pass. All tools need to be acquiring data across the chosen 60m interval. Repeatability should be within tolerance allowing for variations for statistical tools and pad contact tools.

Gamma ray curves should be free from non-repeating spikes.

All necessary corrections should be applied on every log before delivery.

2.1 Well Design

Depths below are prognosed and should not be used on log headers. The actual numbers are available from the Wellsite geologist.

2.2 Wireline Personnel

The Baker Hughes Wireline standard crew requirements per shift,

1 x Field Service Engineer

1 x Lead Operator

1 x Operator (Welltec cross trained personnel)

2.3 Run Numbering System

A run reference consists of a run number and a trip number. The run number increases with every job/rig-up on a well for a series of logs. The trip number increases with every descent of a logging run into the well i.e. miss-runs will increment the trip number.

Run 1 Trip 1




Refers to the first descent into the well on the first job on the well – for instance the first run in the 12.25” section.

Run 1 Trip 2

Refers to the second descent into the well on the first job on the well.

Run 2 Trip 1

Refers to the first descent into the well on the second job on the well – for instance the first run in the 8.5”. section

2.4 Communication

All communications from the Wellsite to Lundin should be routed through the Lundin Wellsite geologist AND the Lundin drilling supervisor.

2.5 Data

Distribution of wireline data from the rig will be done through the Welllink Wireline remote witness and WellLink data distribution and retrieval services. These services can be accessed by logging on to www.bakerhughesdirect.com and navigating to the required sites. Email distribution of data will only be used as a backup to the Welllink Wireline system.

During logging, an activity log entry should be recorded on the chat page approximately every hour from the start of rig-up. If the operation delays, or is expected to delay, for a period longer than an hour, the wireline engineer will note this in the chat page explaining the reason for the delay. This will ensure that progress can be determined clearly by those monitoring the job through Welllink Wireline.

Access to Welllink Wireline and WellLink is controlled through a per-well access list maintained by Baker Hughes’ Beacon Centre staff. Required additions to or deletions from this list can be can be communicated through [email protected]

4.1 Proposed Logging Sequence

4.1.1 Continuous Logged Runs

1. Hold Tool Box Talk with all personnel involved with the logging operation.

2. Rig-up the tool strings

3. Perform a function check in with the tools in the derrick.

4. If required install / adjust positioning devices if not done during the rig-up.

5. Zero the tool string on the drill floor, making sure that the correct zero point and delay is used. Note the relevant information on the depth control sheet.

6. If required install radioactive sources in the tool string – all barriers in place and announcements to be made.

7. Continue to RIH, slowing down through restrictions.

8. Perform pick-up weights every 500 m down

9. If required perform before-log verifications.

10. Each run to be correlated depth to LWD GR, Check with tally

11. If required record a down-log while on the way to TD, otherwise RIH directly to TD

12. Log up the main interval as per requirements specified above.

13. If required, stop in the casing shoe and perform after log verifications.

14. Perform repeat log as per Lundin instructions.

15. If the tool string contains RA sources, safely remove the sources per standard operating procedures.

16. Perform required after log verifications if applicable.

17. Rig down the tool string.

18. Ensure all tools and accessories are accounted for. Report any damaged or lost equipment to the log witness, drilling supervisor and operations geologist.

19. Prepare cablehead for the next run.




5 Risk Deployment Management

5.1 Tension Simulation

The tension simulation for all runs has been performed with the following deployment risk mitigation measures:

Heavy Duty Wireline (7Q49RTZZ-EEHS, 30 000 lb breaking strength)

Deployment of Welltec Tractor

5.2 Stuck Tool Procedure

In case of a wireline tool string becoming stuck the following procedure will be followed to retrieve the stuck tool string.

1. In case of the tool sticking pull to 55 % of the LWR and hold for 2 min. If there is no sign of the tool moving, slack off completely and immediately proceed with (2).

2. Pull up to 70 % of the LWR and monitor tension carefully for 10 minutes. Inform the Drilling Supervisor as soon as possible that the tool has become stuck.

3. If during (2) there is indication that the tool is moving keep 70 % of LWR pull on the string and monitor the tension. If no further tool movement is observed continue with (4).

4. Slack and pull to 70 % of the LWR. Hold 70 % of the LWR for 5 minutes while closely monitoring the tension.

5. Inform Drilling Supervisor, Town Duty Roster and relevant Town Drilling Personnel.
