What well pressure control is:
Well pressure control is the most critical consideration in the planning and performing
any well servicing operation.
The awareness of well pressure control in the prevention of injury to personnel, harm
to the environment and potential loss of facilities, must be fully appreciated by
planning engineers and well site personnel. This appreciation must include a sound
knowledge of legislative requirements, completion equipment, pressure control
equipment and operating practices and procedures.
‘Well Intervention’ and ‘Workover’ are commonly used terms to describe servicing
operations on oil and gas wells and which have, in the past, had many different
interpretations. However, in general, ‘Workover’ describes well service operations on
dead wells in which the formation pressure is controlled with hydrostatic pressure.
Workover operations are carried out by a drilling rig, workover rig or Hydraulic
Workover Unit (HWO) where the Xmas tree is removed from the wellhead and
replaced by blow out preventer (BOP) equipment. ‘Well Intervention’ is a term used to
describe ‘through-tree’ live well operations during which the well pressure is
contained with pressure control equipment. Well Interventions are generally
conducted by wireline, coiled tubing or snubbing methods. Snubbing operations are
now usually conducted with HWO units.
About the course:
The certification program is designed for equipment operators (Level.1) and
Supervisors (Level.2) and covers the following operations:
• Wireline Operations
• Coiled Tubing Operations
• Snubbing Operations
Who is this course for:
This course is designed to train personnel in Well Intervention Pressure Control.
Well pressure control equipment used by wireline, coiled tubing and snubbing units is
so termed as it must control well pressure during live well intervention operations. It
significantly differs from BOP systems used on dead well workovers. As most well
servicing is now carried out by these live well intervention methods, it is essential that
these are fully addressed during this course. The term Well Control specifically
applicable to drilling or dead well workover operations are not addressed in this
manual. However, it is necessary to review Production Well Kill Techniques and have
a thorough understanding of Pressure Basics to minimise risks involved when placing
fluids in the well, whether it is to provide a barrier or when performing a well
intervention activity.
To have an understanding of well operations conducted by live well intervention
methods and the associated pressure control equipment, it is first necessary to have,
or obtain, a basic knowledge of completion designs, completion equipment, practices,
well service methods and their applications. An overview of these activities is given in
the course with a multitude of exercises the student can work through to review their
knowledge.
Training in well intervention well pressure control is an essential part in ensuring the
competence of personnel involved in the planning and carrying out of live well
servicing operations.
The Certification Standards are based on a detailed analysis of the pressure control
knowledge that Wireline, Coiled Tubing, and Snubbing personnel require to perform
their jobs safely. The method assessing the performance of an individual is by written
examination covering Completion Equipment, specialized Pressure Control
Equipment operations, and Principles & Procedures. Each candidate is required to
complete a written test paper on the following:
• Principles & Procedures
• Completion Equipment
• The operation disciplines are Wireline, Coiled Tubing or Snubbing equipment.
Candidates may choose to take one, two, or all three of the operations disciplines.
Candidates should note that they must pass all nominated papers in order
to gain a certificate.
