Worked as an Asso. Drilling Engineer, I have been involved in developing aerated drilling fluid for Geothermal wells projects. Geothermal formation has different characteristic comparing oil and gas formation. Geothermal mainly has igneous rock while oil and gas mostly sedimentary rock. The Geothermal well drilling process is basically similar to the process of drilling the wells of oil or gas. Formation pressure found in geothermal drilling is smaller than the hydrostatic pressure of the mud used when drilling. Therefore, when drilling mud is applied, its pressure will exceed the formation pressure. Then drilling mud will be lost and enter to the formation itself.
For the drilling team, understanding pore and fracture pressure is the key to optimize the aerated drilling implementation. Aerated fluids is common remedy for lost circulation in geothermal drilling. The bottom hole pressure (BHP) or ECD is to be maintained such that it will ‘balance’ the pore pressure. The utilisation of aerated fluids allows for full circulation of drilling fluids and drilling cuttings back to the surface while drilling through permeable formations. During the planning phase, software and formulas spreadsheet were used to model the pressure profile.
I have an experience to work in drilling engineering area (office and site). I have got to spend several weeks working on a land drilling rig. On my first day, I was introduced to the whole team and got an insight of what it really means to put safety first. I also learnt about the nature of office and site work, which, I believe, will help me decide on my future plans. I was working with projects that take months to complete and use the most advanced technology in the industry. This was the first time I had to actively think about the task at hand and use all my knowledge. I also noticed how software engineers work at a typical engineering job. It was an amazing experience and great to meet all the people who work at drilling rig in the different locations. I am very grateful that I was offered this incredible opportunity.
This morning, I read an article on the “Energia” which discusses about the Pertamina’s journey to create drilling standardization for all Pertamina’s subsidiaries. An oil and gas industry relies on the sophistication and success of drilling operations. In other words, there has never been an oil and gas natural resource obtained commercially without drilling. Drilling operations is a vital role to continue the plan of the subsurface team (Exploration), so that oil can be lifted to surface to be produced. Without these activities, the presence of petroleum and gas cannot be proven and produced to the surface. It also needs a high investment. To rent a rig only, for example, reaches 30 thousand dollars per day. In additions, the rig performance is depends on its maintenance. Therefore, an appropriate inspection must be done regularly.

So, what is “Pertamina Drilling Way”? Pertamina Drilling Way (PDW) as part of Priority Initiative made by Pertamina’s Upstream Directorate in order to improve drilling performance. The PDW is summarized in a guidebook as a guide to standardizing the upstream director’s subsidiary drilling activities. For example, most drilling designs are carried out according to the company custom. They might claim it as a best practices for their field case which is (sometimes) contrary to engineering aspects. The last two cases are the most valid examples. One overseas, namely, the incident in the Gulf of Mexico which makes BP almost bankrupted. One more from within the country, namely the Lapindo case, a heartbreaking tragedy that has hitherto have not ended yet.
PT Pertamina (Persero) needs a great miles to compile Pertamina Drilling Way (PDW). PDW does not automatically guarantee an increase in production. It only makes sure the drilling goes according to the plan and run safely. There is no case in the middle of the drilling operations, the rig was damaged which makes the activities had to be stopped due to the technical/non-technical issues. So far there are three companies that carry out these guidances, namely PHE, PGE, and PEP. From this fact, it is clear how important and central a drilling activity is to bring Pertamina into operational excellences.

Entering the “real world” after graduation for Second Time (First Bachelors degree, Second Masters degree). I am feeling lost, scared, lonely, and confused. In Psychology, it is a normal symptoms which is common in a person’s 20s-30s. This is literally thing called “quarter life crisis”. For everyone out there who are struggling with your quarter-life crisis, you are not alone. I am feeling anxious too, because no one ever told me how to be an adult. There are so many issues that I am dealing with: career, imperfections, social life, spiritual and etc. I am facing the truth that people will come and go. Most of them will go and you’ll live in a smaller circle.
Petroleum is the most valuable commodity in the history of the world. But, many people says 2020 will be the year of data. Is data worth more than oil? Data is more valuable than oil. It can be used by many people simultaneously without being depleted. In a digital economy, companies have started treating data like an asset. We live in an age where running business with the help of data is the new standard. Data help us to know which of your products are currently hot items on the market. It is an important information that reflect personal data of costumers on the web searches. Google and Facebook have made billion dollar businesses from this data.
“If data were petroleum in the artificial intelligence era,
then China would be Saudi Arabia”
The founder and chief executive of Beijing-based Sinovation Ventures told that China would be the new Saudi Arabia. China is the country with massive number of internet users (greater than the United States and Europe) which provide the big data. China is projected to lead the world in artificial intelligence in less than 10 years to become the largest economy. If data is ‘the new oil’, then the data scientist functions much like an oil refinery, converting data into insights that can both save money and generate capital.

Whenever people from your past spread negative stuff about you, just remember that all they know is a past version of you, and now you’re not that person anymore. You don’t need to fight back or prove anything, just keep moving forward. What’s done is done and what’s gone is gone. One of the life’s most valuable lessons is learning how to let go and move on. Looking back at your good memories is fine but never let the past stop you from moving forward. If you want to fly on the sky, you need to be an eagle. If you want to move forward, you need to let go of the past and don’t let negative people drag you down.
