Directional drilling is defined as the practice of controlling the direction and deviation of a wellbore to a predetermined underground target or location. The most common deviation tools for directional drilling are steerable motor assemblies (or so-called positive-displacement motors - PDMs) and rotary steerable systems (RSSs). Adjustable-gauge stabilizers, known as “2D rotary systems,” have become quite popular to run with the rotary and PDM assemblies to control inclination. Whipstocks, especially casing whipstocks, are used routinely to sidetrack out of cased wellbores. (Source: Petrowiki)
Imagine drilling for thousands of feets and suddenly your drillpipe becomes stuck. You try everything possible to release your drillpipe and resume drilling, but the more you keep trying to free your pipe, the more frustrating it becomes. Starting afresh is not an option either, as it will be too expensive and time consuming. In times like this, we need to sidetrack the well. Just drill a new hole right from the troublesome one and continue our journey to the payzone. This is where a whipstock (photo) comes in. A whipstock is also used to deliberately change the direction of the well for example in directional drilling. Another example is when we discover to our horror that the bit is just drilling towards the wrong direction, we make use of a whipstock to correct this and restore the bit back to the direction that leads us to the payzone.
Boa noite galera!! Continuando com os cursos importantes para trabalhar em uma plataforma, hoje escolhemos o HUET. O curso HUET – Helicopter Underwater Escape Training – também é conhecido, no Brasil, como Treinamento de Escape de Aeronave Submersa. Trata-se de um treinamento básico de procedimentos de segurança para escape de helicópteros em caso de acidente quando voando sobre a água. Este treinamento vem sido exigido cada vez mais pelas empresas, principalmente aquelas cujo acesso a plataforma é feito exclusivamente por helicóptero.

Understanding oil and gas terminologies - well completions
What does it mean to "complete" a well? For sure, if we're going to complete the well, that means we're not done with what we ought to do.
After going through the trouble to explore and drill a well, the next step is not to start producing. The well has to be completed first in order to optimise production and ensure surface control of what's going on in the well.
Well completions is to an oil/gas well what icing is to a cake. It may not look like much on the surface but it's really crucial.
For example, casing and cementing the well to make it easy to control production from the well, perforating the well to open up the reservoir to producing through the casing. All these fall under well completions.
There are other things to do but these are just a few. Well completions is a very important aspect of the production process.
Sitting comfortably in the Norwegian Sea is Heidrun, a floating concrete tension leg platform. The field was discovered in 1985 and was brought on stream (started producing) ten years after in 1995.
Projects in the oil and gas industry are usually long-term and it can take years before companies get back the original capital invested in a project. Yet, when it begins paying, it will be worth the wait.
