Name: Mr. Jack Whitten Name: Date: 12/16/2008 Date: Time: 13:15 CST Time:

ABANDONMENT The following is a summary of NRC and/or Agreement States regulations that mus tbe followed when abandoning an irretrievable well logging source(s). The specific regulations are found in 10 CFR 39.1 5 and equivalent regulations in Agreement States. An irretrievable well logging source means any licensed radioactive sealed source that becomes lodged in a well and cannot be retrieved after reasonable efforts have been made to recover the source(s).

If a well logging source is irretrievable, the following requirements must be implemented.

a) The source(s) must be immobilized and sealed in place with a cement plug. The cement has to be dyed red in Texas as a condition of the Texas Railroad Commission (others occasionally).

b) A mechanical deflection device must be set at some point in the well above the cement plug to prevent inadvertent intrusion on the source, unless the cement plug and sources(s) are not accessible to any subsequent drilling operations. The mechanical device can be devices such as a whipstock, old drill bit, etc. For LWO, drillpipe and/or collars left on top of the BHA usually are approved as a deflection device.

c) A permanent identification plaque, (supplied by the STC RSO) made of stainless steel (or brass, bronze and monel), must be mounted at the surface of the well unless the mounting of the plaque is not practical (Le. subsea completion).

The STC RSO (or his designee) wil l notify the NRC or Agreement State of the abandonment plan developed by/with the client. The NRC or Agreement State must approve the abandonment plan prior to implementation. The federal and/or state oil and gas well permitting agency must also approve the abandonment plan. The contact with the well permitting agency is the responsibility of the well owner/client but we should advise him/her of that fact as a courtesy.

If any changes must be made to the abandonment plan submitted to the NRC or Agreement State, the STC RSO must be informed so that he/she can get approval of the modification, as appropriate. The actual abandonment must not begin until any abandonment plan or modification to that plan is approved by the appropriate agency.

The STC Radiation Safety Officer must file a written report with the NRC or Agreement State after the abandonment. The facility management shall file a written report within 7 days to the STC Radiation Safety Officer. The facility report should cover the final abandonment details such as:

a) Actual date of abandonment.

b)

c)

d)

e)

Any changes in the data sent with the approved abandonment plan.

Detailed Well Schematic depicting location and depth of tool(s), source(s), drill pipe, plugs, deflection device etc.

Any information pertinent to the abandonment that the STC RSO may not have for his/her final report.

If all data sent to the STC RSO is still applicable for the final report, an e-mail or fax is to be sent to the STC RSO confirming that fact so that he/she can be ensured that the data sent to the appropriate agency is totally accurate. Most facilities send a completely new report since many these documents often are incomplete or are poor quality fax reproductions.

If there are any questions regarding these procedures, discuss them with your Operations Manager.

FACILITY MANAGEMENT MUST ENSURE THAT THE FINAL ABANDONMENT REPORT IS SUBMlllED TO THE STC RADIATION SAFETY OFFICER.
