INTRODUCTION The purpose of the Rig Inspection and Acceptance Booklet is two fold. The first function is to determine by means of an on site inspection those rigs whose equipment maintenance, condition, and personnel make them capable of efficiently performing the work planned. This function is fulfilled by the “Inspection” section. The second section, the “Acceptability Test”, is intended to be applied once the final rig choice has been made. This section provides performance tests, more detailed inspections, and other criteria which the rig should pass prior to final acceptance by Pluspetrol. Realistically, depending on the location and status of the rig, there are times it will not be practical to perform some of the tests given in the “Acceptability Test” section prior to putting the rig on contract. It is the intent, however, that whenever possible this be done.

PROCEDURE 1) The Tenders for drilling rigs when sent should require presentation of: a) b) c) d) e) f) g) h)

Operating Manual complete with system drawings. All valid certifications of applicable regulating agencies. Equipment list with specifications. Standard Maintenance Program, failure forced and preventative maintenance records, and performance statistics. Spare parts inventory. Safety and Training Program. Safety records pertaining to LTA & NLTA. Resume 5 as outlined within. Note: A bid will not be considered complete unless the above items, when requested, are received along with the submitted commercial section.


2) The specification of each major equipment groups (main body and/or applicable appendix) should be filled out when the tenders are received. A comparative study of the contractor supplied equipment should be developed to aid in effective short listing of contractors. The specification sheets should be filled out as completely as possible prior to the actual field inspection. 3) Prior to actual field inspection, questions pertaining to maintenance records, failure forced repairs, and preventative maintenance should be answered (main body and/or applicable appendix). 4) Arrange a meeting with the individual drilling contractors management for the purpose of organizing an inspection tour. Insure both the contractor Operations Manager and Drilling Superintendent will be present. Use this opportunity to informally interview them. Also, determine the present and near future operation on the rig - this will effect the type, amount, and difficulty of inspecting to be performed. Note: Make sure you are in legal compliance prior to the actual rig visit! 5) Upon arrival at the rig, arrange an informal meeting with all supervisory personnel. It is very important to establish a good rapport with the contractor's supervisory personnel. Explain what our purpose is. Informally interview them separately while inspecting their area of responsibility. 6) Make a general walk around inspection of the rig. Take note of the housekeeping, obvious safety hazards, and organization. Also, continuously monitor the personnel morale. 7) Follow the inspection guidelines established in this document. The order of inspection is not necessarily important and if more than one OPERATOR person is on the inspection tour, split the workload. The operating status of the rig will affect the extent to which you can inspect equipment. Make note of equipment variations from specifications. Why do they vary? Remember, the major purpose of this exercise is not to answer questions, but to determine the units overall operability and apparent dependability!


8) Following the inspection of all rigs, the person in charge of the inspections should notify, in writing, the Drilling Superintendent of the results. The notification should state whether or not each rig inspected is deemed capable of efficiently drilling the well or wells planned. Any major advantages or disadvantages to the use of any of the rigs should be stated. Also, any modifications which would be required should be pointed out. The rigs inspected should be force ranked in terms of their overall apparent dependability and suitability. The completed "Specification" and "Inspection" sections for the rigs inspected should also be forwarded to the Drilling Superintendent and Drilling Manager at this time. 9) After the region has selected the rig to be used, then the acceptability test in each section (main body and/or applicable appendix) should be performed. Rig location and status permitting, the acceptability test will be completed prior to the rig being placed on contract. This testing phase should be carried out by the person in charge of the initial inspection and/or the drilling foreman and drilling superintendent assigned to the project. The drilling manager should be notified as soon as possible when the acceptability test is completed. Any items not acceptable should be documented in this booklet, and in letter correspondence to the Drilling Manager. The person in charge should make recommendations in this letter to accept the rig as it is, reject the rig until deficiencies are corrected, or to accept the rig as it is with the understanding from the contractor and management that the deficiencies will be corrected within a specified time frame. In the latter case, there should be no future shut downs associated with the repair or loss of efficiency. 10) A complete copy of this booklet and all pertinent correspondence should be forwarded to the OPERATOR Drilling Manager office.


INSPECTION SECTION CONTRACTOR PERSONNEL Specifications A resume for all key personnel should be requested with the tender for drilling rigs. The resumes should include items normally shown, i.e., age, education, Years of experience, etc. They should additionally indicate operating experience on the rig being proposed, a copy of their last two personnel evaluations and a listing of all valid certificates held with the date of expiration. Key personnel to obtain resumes from are: Contractor Operations Manager, Drilling Superintendents, Toolpushers, Drillers, Medics (Safety Supervisors), Chief Electricians and Electricians, and Mechanics. Inspection This may be the most important part of the rig inspection. Our objective should be to gain as much truthful information about the rig and the contractors organization as possible. How questions are answered is equally as important as the answer itself -- do they mean what they say! Although you will have to steer the conversation, keep the contractor in the lead, explaining details. Review resumes of all key personnel and personally interview as many of these as possible. In general, points to determine include length of time the individual has worked in his current position, length of time with this drilling contractor, length of time on this rig, the individual's opinion of the contractor and the rig, and his language capabilities. Have the individual describe his job function and the rig equipment for which he is responsible. Try to determine how well the individual knows his job. Discuss with the previous operator the performance of the rig crew and any problems he experienced. Based on your findings, comment on any individuals you recommend to be replaced if OPERATOR contracts the rig.
