Core Core sampling is very important to be done to know the petrophysical property of the formation. It is usually shaped as a cylinder, since it is obtained by using coring bit, the drilling bit which drills the formation with a hole in the center to obtain the sample while drilling, which is called the "core bowling". The cost for coring a well is very expensive, and not all wells will be cored. Also, instead using the conventional whole core, people may also use the sidewall cores, which will take the samples from the wall after the well has been drilled by using wireline. Sidewall cores are cheaper than the conventional core explained above, but the data will not be as complete as conventional core. The advantage is the price and the time which is only spends hours, instead of days. The sidewall cores are retrieved by two ways: Rotary sidewall coring and percussion side wall coring. Rotary sidewall coring will use a special small core bit which will poop o...

Today is the Black Friday. I'm looking for discounts and stuffs since the discount gonna be as low as 70% and it is very worth it for me!  And it really reminds me about the upcoming Christmas eve, Which is very special and glad to see that it will be spent with my family warmly and cheerfully! I remember last year's Christmas, that was not really good since I was hospitalized in the panic attack. That time, I didn't even know that it was the panic attack, felt very dizzy all day long, and couldn't join my family to have Christmas party. Horrible! I used to love this song, All I Want for Christmas is You, which is really warm and full of hope. But as time goes by I realize, it is not really wise to hope for a perfect Christmas with someone adorable such as in the song. People should realize that the perfect Christmas they have is the one that they receive, and spending the Christmas the way people want will not make it more special, or in other words, h...

Hi, Welcome here again! So, now I remembered the time when I played music a lot. I spent quite a long time to find some of the records. I've just realized that it's been a long time I haven't opened my soundcloud! Unfortunately, I didn't remember my soundcloud profile so I should go through posts in Facebook where I share the link.  This one in the video was created after mid test when I was in the college. The singer's name was Cika, She has a great voice and she could have been a great idol if she choose to be a singer! The sound mixer/editor was Rakananda, a friend of me who has already been in US pursuing his master degree. Perfect timing, where someone who simply loves to play guitar meet someone who loves singing and someone who loves sound mixing! We also joined a student band, and played in events and competition. It was actually a kind of batch band, every batch have their own band but with the same name. That is why, the pride will come as t...

It has been a long time I haven't played guitar.  There are a lot of things to do in Bandung, while my lovely guitar is in Tangerang. You know what is really burdening people who love to play music? Sometimes, people don't really see any purpose of playing music. It is very though to be a musician, you better leave everything behind or you will never be famous. Are they underestimating? No, they are not. It is the reality! There are a lot of street musician who play music better than me, or even play better than some famous artists. But unfortunately, they haven't even had their own house in their 30s or 40s. People should be very outstanding from the crowd just to be famous, not to mention the luck factor beside the hard work itself. Indeed, it is the pessimistic view of the society. But that is not the point of view from the musician itself. I hope some other people have the same view of me, sometimes I play guitar just because I love it, and simply because I mis...

Watermelon art in wedding ceremony The time will come, sooner or later, where one by one, the people you know are getting married. It is the time when some people might feel insecure to see them married! There are a lot of tradition that are commonly believed in the society. Sometimes people believe they should bring their significant other to their friends' weeding ceremony, while other people unlucky enough to have that significant other yet. Yes, that's me! LOL In Indonesia, the wedding ceremony is very sacred since it contains the symbol of religion and traditions (adat). The preparations also have a long story, since there are a lot of different practices even in the same tribe or local inherit. It need an intensive discussion on how the celebration should be done between the family, and that makes the preparation need a lot of head. Most of the time, there are sessions of ceremonies to be done. First is to accomplish the religion direction about the marriage....

I still remember this beautiful city. Paris. All the corners of the city were artistic and magnificent. There were a lot of people from various races came, to enjoy the panoramic beauty of the city. I also remember that the foods were delicious, and it wasn't hard to get Asian food there. With many other countries to be explored for the rest of my life, going there twice or three times will be still great. Not to mention the famous Eiffel Tower that play beautiful lamp attraction every hour. It was too beautiful that someday I would like to enjoy it again with the special one. This morning, I woke up with pray for Paris in an Instagram account. I turned on the TV, and saw no breaking news or live news, so I though it will be alright. But then I opened the Internet from my phone, and was shocked that the uncivilized act had happened in Paris. about 100 people were dead, and the attacks happened in several area. I open the Youtube live streaming and realized that the conditi...

Kit Kat is very popular gift you may expect from people traveling to Japan. They are very unique, since they only sell some variants in some area in Japan. They don't export the special Kit Kat. It is become famous among tourists and somehow the exclusivity makes people search for them. And the last time I went to Japan, i brought home some variants which are exclusive in Japan. What a luck. I taste all of them. I felt some differences, although the main taste were all chocolate and milk. The  most interesting one, in my opinion, was the wasabi, since it was a little bit spicy. Being exclusive is one of the power of Kit Kat, not to mention about the taste of course. Since they are representing cities they were made, I remember one type of this kind in Indonesia. Yes it is exclusive from a city, yes it is well packaged, and yes it is popular among young people, It is called ALMOND CRISPY CHEESE!! It is only produced in Surabaya, East Java. Very crunchy and k...

Rainy season is in the town! I woke up in the morning with the sound of rain drops, cold weather & I stayed a little longer in the bedroom, since the comfy warm blanket, morning talk-show in the television, and FREElance time were all perfect combination this morning. It is all that people need recently, the rain. The heat was very horrible, with the smoke and fire-forest problems, people were hoping for the rain. Now, the smoke become less, and in near future, people will enjoy the cool air every time they go to work or go home. These days are great for cups of hot chocolate! Yummy! In my opinion, it will always about the perspective that we see the condition. Some people are stressed that in the future they will face other problems: water-flood, heavier traffic, wet clothes, or hardly bring umbrella anywhere. People can not deny, everything come in a package. since I love playing guitar, then I should accept that sometimes my fingers should bleed. I want to get a better...

Before talking about mud engineering, we should understand first the importance of the mud itself in drilling a well. These functions are remove cuttings from well, suspend and release cuttings, control formation pressures, seal permeable formations, maintain wellbore stability, minimizing formation damage, cool, lubricate, and support the bit and drilling assembly, transmit hydraulic energy to tools and bit, ensure adequate formation evaluation, control corrosion (in acceptable level), facilitate cementing and completion, and minimize impact on environment One of the most significant uses of mud is based on its weight (density). This is mainly related to the function of controlling formation pressure and removing cutting from the well. The mud weight should be adjusted in time and precisely to ensure the mud does its functions. When the mud weight exceeds the fracture pressure (the maximum pressure the formation can accept before it breaks), the formation may fracture and lost c...

Renewable energy is an interesting thing to be considered as working field in near future. This energy source is still undervalued, and it can be analyzed that the performance will be "BULLISH" (as what the stock traders say) in about 10 years. But why renewable energy is that important? First, a consideration of people to convert to renewable energy is about its sustainability and cleanness. Renewable energy will be sustain longer than fossil energy, and also less harm to the environment. As it can be seen, on the long term issue, renewable energy should has been the major source of energy. But back to the basic, all these energy sources are used to get profit, and this was the main disadvantage of renewable energy. Petroleum industry is more profitable than the renewable energy. It seems that the renewable energy still need some years to be considered. Moreover, there are some step before renewable energy to be considered after petroleum industry, named unconventional...

I am quite interested in some stop motion people did for other people's birthday (mostly!) And this one is a stop motion video I did for two of my old friends. They have the same birthday so it's quite kill two birds with one stone. So, we had a horrible joke about the future. So I went to Petroleum Engineering,  one went to electrical engineering, and another one went to computer engineering. We had joke that they would find me in the gas station helping people with their car, also when I looked up to the electricity pylon, My friend would be there fixing things, and the other one would sell computer in electronic center!! That was an old joke, we really expect things go simple and easy, only relax and chill out. I once think what if I visualize the idea, then this video was created.  It is quite an old thing, and we all have different communities and lives in different cities now. I had a lot of effort and time to do this video, and proud enough with the result, s...

Tidung Island, a fascinating island in the north of Jakarta mainland, is a village of Kepulauan Seribu selatan, Jakarta, Indonesia. We may find a very distinctive atmosphere in Tidung Island, although it is still part of Jakarta. Just 3 hours boating from the main land, People may find time’s getting slower in Tidung Island. People will find the local works less stressfully as fishermans, and less polution too. Indeed, since the Island only has motorcycles as the main transportation mode. No car, and a lot of bicycles! A little advice to go to district “Pulau Seribu” (literally means a thousand islands), they have each island with different range of prices to stay, and also some special islands only good to do specific activities. For instance, the price range for Bidadari Island is much higher than Tidung, with different expected accommodation. But don’t expect low quality room in Tidung. The locals are really open to tourists and people will get homey houses, air conditioned room...
