Tapis is light sweet crude. Low suplhur content (0.04%) which produces full range naphtha (light and heavy), butane, jet kero and high grade diesel. Such crude only need fractionation to obtain their products. Of course they will try to get rid of as much sulphur and H2S in the product. Also fine sand is found in any crude which is not good for engine combustion. But nothing is perfect when it comes to sulphur removal.

The oil produced at Tapis is the same grade in all 4 platforms (platform may have increased for DD, my dad's time no such thing as DD and MWD) due to the fact that they share the same geological faults, age, temperature, porosity and depth. There is a reason why only Tapis had sweet light oil.

Tapis is not found till later in my dad's career. Before Tapis, other oil fields are sour crude and some even have mercury.
Thus, this explains why PD oil refinery had a hydro treater. Hydrocrackers are use to improve the oil performance for petrol.

If things had changed in the Tapis field that I am not aware (I am working overseas btw), my sincere apology for any doubts created, we are here to share knowledge. I am here to share my dad's long life experience in that field.

As said, it is simple, your logic sure will work if you eat yesterday and then you no need to eat until you dies.
But the fact already proven that your logic fails. No need to keep on bringing your dad's story.
Even if you want to bring up 40-50 years stories your logic still fails as hydro treater are built together with crude distillers. ESSO refinery are about 40 years.
Your first statement already shows that you know nuts on crude processing. Even the lightest product of LPG still need to remove sulphur.
When a crude is tested to have 0.04%wt of sulphur, once processed it will become higher.

I am aware that sulphur removal is not perfect. Hence my previous statement "But nothing is perfect when it comes to sulphur removal". Read my previous statement properly.

PD refinery obviously process other Malaysian oil field crude BEFORE Tapis was discovered. Tapis was only discovered only on 1969. No one builds a refinery without a HDS, that is plain stupid as each oil field are different from others when it comes to quality and sulphur content. Assuming PD only refines only Tapis oil (which NEVER HAPPENS), sulphur content will build up (even with the 0.04% sulphur) sulphur will always build up in concentration.

Regardless is good or bad crude, good or bad crude are always stored, in which later it will be blended with other crude to produce the desired products based on market demand.

No oil and gas company will take a crude to be burned staright to a car. That is plain no brainer either.My first statement was just a metaphore of how good the oil is at Tapis is.

What makes you think I dont know anything about refinery? Once again dont assume.

2. Some of the DE in operators came from services company and previously a field engineer such as mud engineer or MWD. Most of the DE come from fresh grad and gains experience from there. Drilling Contractors DONT HAVE a Drilling Engineer.

Is it possible that a drilling engineer from operator can work in oilfield service company?

From my understanding, it is best to work in an oilfield service company to gain working experience, before joining the operator. The thing is that if I cannot seek employment in an oilfield service company, perhaps I should apply for entry-level drilling engineer in operator.

may i know whether graduate from other degree will be able to join O&G companies?

Graduate from where and field of study?

bachelor of science - statistics from local university UPM

Am I the only one here thinks that one particular commenter here are nothing but pain in the arse?

TEG is just dehydration right?

PTS 20.04.10.10 is another good reading material for those who are interested in glycol dehydration.

of course it is possible. my U senior who was a petronas scholar resigned from petronas after less than one yr service to join slb. she paid the penalty but i guess it is really worth it. now she's working/staying in houston, still with slb.

working with operator vs oilfield services....both have pros and cons...depending what is 'best' means for you...

if you are fresh grad, apply all....the competition is very very tough out there. quick google search can tell you how many people being laid off in this 2-3 month and still on going...get in first, build your network, gain experiences, work hard and go up the ladder...keep humble...

We're just village heroes.
Office workers who does not develop, just copy and paste.

So we chose to.........ignore 

Anyways for you guys who have been wondering what we do upstream to remove impurities from gas, the TEG is generally our largest processing step on the GPF.

It's a pretty good presentation and goes over the basics.

Anyone know of a certain French Oil & Gas company that is based in KL Sentral? I received a very weird call today, refused to disclose their company name and no idea how they got hold of my details.
