Oil and Gas Well Technology Series

Level 3 City and Guilds Certificate in Oil and Gas Well Technology

View available purchase options

The Oil and Gas Well Technology series will help candidates achieve a broad understanding of the operational techniques of oilwell drilling, drilling calculations, completion and wireline well-servicing. It includes the function and construction of a representative selection of tools and equipment used in the drilling of oil and gas wells; the completion and wireline well-servicing of oil and gas wells; while providing guidance and practice on the calculations required during drilling operations.

The series consists of 3 modules which include workbooks and a ‘Guide to open learning’:

  • Oilwell Drilling Technology
  • Oilwell Production Technology 
  • Drilling Calculations

These self study modules enable the candidate to select learning materials that suit his or her own particular requirements. Modules can be studied at the candidates own pace and should be studied in the order set out. The study time needed will vary from one module to another, and from one individual to another – we recommend between 40 - 60 hours for each module. 

Candidates can register for modules individually or enrol for the complete series – modules are non-transferrable and can only be assigned to one candidate. Each module is assessed by examination and an individual certificate endorsed by City and Guilds awarded to successful candidates. 

Each exam which is passed successfully will contribute to one certificate of unit credit towards ‘The Certificate in Oil and Gas Well Technology'. The certificate will be awarded after all 3 Certificates of Unit Credit have been accumulated.

Exams

There is a written exam at the end of each module. 

Exams can be held any time at an approved venue  i.e. there is no set time limit between starting a module and sitting the exam.  

When a candidate is ready to take the exam an invigilator must be appointed on their behalf. The ‘Invigilator’ may be a Training Manager, OIM or Senior Manager. The invigilator is responsible for the receipt of the exam papers, security of the papers, invigilation of the exam and return of the paper. 

The invigilator must contact our team at the UK office to arrange the dispatch of exams.  Included with the papers will be an invigilation form for signature of the invigilator and rules and procedures for the exam.  

Candidates may sit the exam, free of charge at our offices at Minerva House. If this is not possible, then we suggest you contact your local college or learning centre to arrange to sit the exam on their premises. These arrangements must be made by the candidate. Some colleges may charge an invigilation and room hire fee which the candidate will be responsible for. 

Oilwell Production Technology and Oilwell Drilling Technology are two hour closed book written exams. Section A has 20 short questions similar to the Test Yourself in the books. Section B comprises of three questions of which two must be answered – these require good, neat, correctly labelled drawings and a good descriptor. Drilling Calculations is a three hour closed book written exam. There are 20 questions. All questions in the paper relate to the information given in the workbooks. An abbreviation, standard formulae and conversion factor sheet will be given.

Pass Marks: 

60%-74% - Pass

75%-84% - Credit

85%-100% - Distinction 

‘Test Yourself’ questions are available in the workbooks to help you prepare for your exams. 

There is no registration or examination fee. However, in order to be registered to sit the exam, the candidate must have purchased each module.

If candidates do not achieve the required pass mark (60%) a re-sit exam can be arranged at no extra cost, only a pass grade will be awarded irrespective of the result. Should candidates require a re-sit of the same module more than once, there will be an examination fee of £30.00.

Each module is £200 (£190 for digital version), including UK delivery.

International delivery for hard copies will incur shipping charges dependent on location and service.
