IWCF  (International Well Control Forum) is the world class organization in well control which many people know about. A lot of people working on the rig are required to have well control certificates and IWCF certificates are accepted world wide.

IWCF also shares excellent kill sheets used for well control situation to everybody. There are both surface and sub sea BOP version. Additionally, IWCF provides the files in several units. There are a total of 16 kill sheets  and please download the IWCF well control kill sheet from the following links:

Annular Preventers – Well Control Equipment

By | |
12 Comments

Annular preventers are the most versatile well control equipment and there are many names referring it as bag preventers, or spherical preventers. The annular preventers are able to seal around several size of drill pipe/drill collar, work string, wireline, tubing, etc. There are some models which can utilize wellbore pressure to provide additional sealing capability.

The annular preventer consists of a body, a cap, a piston and a rubber packing element. The illustration below demonstrates the drawing of an annular preventer.

How the annular preventers work?

Close – When the hydraulic oil is pumped into the extend port, the element inside will be lifted and squeezed the pipe/tubular.

 

Open – On the other hand, if the hydraulic fluid is pumped into the retract port, the element will be pushed down resulting in releasing the tubular.

The following videos will help you understand how the annular preventer work.

 

 

Nowadays, there are several manufactures providing this equipment such as Hydril, NOV (Shaffer) and Cameron. The models available in the market based on the manufactures are listed below:

BOP Stack Organization and BOP Stack Arrangement

By | | ,
4 Comments

Blow Out Preventor (BOP) is a very important part of well control equipment and the first thing which we would like to discuss in this article is the BOP stack organization. The BOP stack can be configured in various configurations which must be suitable for the operation.

API has the recommended component codes for BOP as listed below:

A = Annular Preventer

G = Rotating Head

R = single ram type preventer with one set of rams, blind or pipe.

Rd = double ram type preventer with two sets of rams, blind or pipe.

Rt = triple ram type preventer with three sets of rams, blind or pipe.

CH = high remotely operated connector attaching well head or preventers

CL = low pressure remotely operated connector attaching; the marine riser to the BOP

S = spool with side outlet for choke and kill lines

M = 1000 psi

How can I know the BOP configuration and rating from the codes?

When you see the code, you need to read upwards from the bottom of BOP stack. Let’s take a look at the following example:

15M 13-5/8” – RSRRA

This BOP stacks has pressure rating of 15,000 psi with a bore size of 13-5/8” inch. There are following BOP component from bottom to top

Rams – Spool – Rams – Rams – Annular ( see the figure below)
