Progressing Cavity Pumping (PCP) System

PCP SchematicProgressing Cavity Pumping (PCP) Systems typically consist of a surface drive, drive string and downhole PC pump. The PC pump is comprised of a single helical-shaped rotor that turns inside a double helical elastomer-lined stator. The stator is attached to the production tubing string and remains stationary during pumping. In most cases the rotor is attached to a sucker rod string which is suspended and rotated by the surface drive.

As the rotor turns eccentrically in the stator, a series of sealed cavities form and progress from the inlet to the discharge end of the pump. The result is a non-pulsating positive displacement flow with a discharge rate proportional to the size of the cavity, rotational speed of the rotor and the differential pressure across the pump.

Gas Lift

In a typical gas lift system, compressed gas is injected through gas lift mandrels and valves into the production string. The injected gas lowers the hydrostatic pressure in the production string to reestablish the required pressure differential between the reservoir and wellbore, thus causing the formation fluids to flow to the surface.

Proper installation and compatibility of gas lift equipment, both on the surface and in the wellbore, are essential to any gas lift system. An extensive range of compatible equipment and capabilities, experienced technical and field support, and in-depth analysis programs complements every gas lift design. Our comprehensive family of value-added products and system components encompasses a broad range of equipment models, configurations and special features to service and provide the right equipment and system solution for all your gas lift applications.

Offshore Works

one of platform at East Coast of Malaysia..

Work start at early morning, using boat to remote platform..see picture jump like tarzan,right?

I just to share with u guys my pictures at offshore.. hopefully it's give u general knowledge to understand offshore works and how difficult to get crude oil (thats why the price of petrol increase every year!!)

this is wellhead area, which consist of wellhead, wing valve, production choke valve,pressure gauge etc.

this is pure crude oil with 10% water cut.

interested? join oil & gas industry now..

Professional Engineer (IR)-BEM

Any candidate who applies for registration as a Professional Engineer must:
  1. Be registered as a Graduate Engineer with BEM; and
  2. Have satisfied the training requirements of BEM; and
  3. Have passed the Professional Assessment Examination (PAE) of BEM or be elected as a Corporate Member of the Institution of Engineers Malaysia (IEM); and
  4. Have been residing in Malaysia for a period of not less than six months immediately prior to the date of application.


  1. Application shall be made in Form B1.
  2. On approval of the application, the candidate is required to pay a registration fee of RM350.00 within two months of the date of notification of such approval.
  3. On payment of the registration fee, a certificate of registration in Form D1 will be issued.


  1. A registered Graduate Engineer is required under Section 10(1)(b) of the Act to obtain practical experience in order to be entitled to sit for the Professional Assessment Examination (PAE) which is a prerequisite to apply for registration as a Professional Engineer.
  2. The candidate shall carry out the practical experience in the following manner as prescribed in Regulation 22(1) of the Registration of Engineers Regulations 1990:

The practical experience that a registered Graduate Engineer is required to obtain under section 10 (1) (b) of the Act in order to be entitled to apply for registration as a Professional Engineer shall be carried out in a manner satisfactory to the Board for a period of three years –

  1. in the planning, design, execution or management of such works as comprised within the profession of engineering;
  2. in engineering research; or
  3. in the teaching in a course leading to a qualification in engineering research; or in the teaching in a course leading to a qualification approved by the Board, and at least one Year of such practical experience shall be obtained in Malaysia under the supervision of a registered Profession Engineer of the same discipline or an approved allied discipline and shall be in fields of engineering practice other than in research or teaching.
  1. This period of training in a local environment is greatly emphasized by BEM as it is of
    paramount importance for the prospective Professional Engineers to be familiar
    with the local conditions and by - laws so that they can comply and practise effectively in Malaysia.
  2. Notwithstanding the above, regulation 22(2) stipulates that if the Board is satisfied for sufficient cause or reason, the Board may in any particular case exempt either wholly or partly the requirements as to the practical experience required to be obtained in Malaysia or the requirement as to the supervision by a registered Professional Engineer in Malaysia; provided that the total practical experience to be obtained shall not be less than three years.

  3. Where there is no Professional Engineer of the same or allied discipline as the candidate in the organisation in which the candidate is working, he may seek the approval from BEM to obtain a Professional Engineer from outside his organisation to supervise his training.

  4. After the candidate has completed the required prescribed training, he may apply to sit for the Professional Assessment Examination conducted by BEM.

What is Hydraulic Lift?

Hydraulic Lift Systems consist of a surface power fluid system,power fluid cleaning unit, a prime mover, a surface pump, and a downhole jet or reciprocating/piston pump. These systems are renowned for their versatility and ability to operate in high volume, high depth environments. One major advantage to either system is the ability to hydraulically circulate the pumps to the surface for maintenance, dramatically reducing well downtime and eliminating pulling unit expenses.

In the operation of a hydraulic lift system, crude oil or water is taken from the storage tank and fed to the surface pump. The power fluid, now under pressure built up by the surface pump, is controlled by valves at a control station and distributed to one or more wellheads. The power fluid passes through the wellhead valve and is directed to the downhole pump. In a piston pump installation, power fluid actuates the engine, which in turn drives the pump, and power fluid returns to the surface with the produced oil and is piped to the storage tank. A jet pump has no moving parts and employs the Venturi principle to use fluid under pressure to bring oil to the surface.

Who's Engineer?

An engineer is someone who is trained or professionally engaged in a branch of engineering.[1] Engineers use creativity, technology, and scientific knowledge to solve practical problems. People who work as engineers normally have an academic degree (or equivalent work experience) in one of the engineering disciplines.
