My Thought on Schlumberger
Having the golden opportunity to perform my internship in Schlumberger made me realize that Schlumberger is not only the largest oilfield service company in the world, but way more than that. Their commitment in service quality, HSE and values are of top notch and had really impressed me. Schlumberger ensure that all employees are well-trained and understand their tasks in-depth. As aforementioned, I am able to utilize the theories learnt back in UTM and from the reading material form InTouch in my everyday task in ACRE. Knowledge on the oil and gas industry, engineering and software helped me to thrive in performance and eased my activities.
Being in a working environment has helped me developed my critical thinking especially when I faced any problems when performing any of the tasks given. The employees here often encourage me to have a sense of curiosity and eagerness to learn. I am often grilled with thought-provoking questions which forced me to think out of the box. This is important as engineers are often asked to solve problems and think creatively and fast to solve a problem. My communication skills had good improvements throughout the industrial training period. In a working place, it is common to have senior engineers that are very knowledgeable. In order to learn new things from them, it is crucial to communicate with them in a proper manner. This in a way did enhance my communication skills as I was required to talk to them in a professional manner. Besides that, I have learnt to attract the audience during my final presentation and my confidence in public speaking boosted high.
I can say that the training provided project assigned during my internship period were very well structured. It was an eye-opening experience to involve and contributed even little in an oil and gas company for the first time in my life. I am more than proud and thankful to have completed my internship in ACRE, Schlumberger under my manager, Scott Thomson and maintenance engineer, Amy Shareena. It was an honor to work with a good team as Subsea and I was very happy to learn a lot of new things from them.
Subsea Landing String inside (BOP)
About Subsea Landing String
The E-Z Tree Subsea Safety Valve is made up on the test string and landed in the subsea BOP stack to provide a safety valve and unlatch system during a drillstem test (DST). After the E-Z Tree Subsea Safety Valve has been landed, pipe rams are closed around the slick joint below the valve assembly to seal the annulus. The E-Z Tree valve assembly combines a flapper valve with a ball valve that can cut up to 15/32 inch. wireline or 1.5 inch. coiled tubing. This valve combination provides the simplest, most reliable system available. Hydrate inhibitor can be injected into the test string directly at the flapper valve. The E-Z Tree valve is connected by a hose bundle to a surface control console on the rig floor.
The flapper and ball valves are opened by applying hydraulic pressure and closed by spring force after bleeding off this pressure. Valve unlatching is performed by applying pressure from the console on the unlatch line. Should hydraulic pressure be lost or the hose cut, unlatching can be performed mechanically by shearing a pin and rotating 14 turns to the right. The complete hydraulic operating mechanism is contained in the latch assembly, which can thus be serviced after unlatching which it is a major advantage over other subsea test trees.
The retainer valve, which closes in conjunction with the E-Z Tree valve, isolates the landing string from the riser after disconnection to ensure that no hydrocarbons are dumped, thus reducing the risk of pollution. The E-Z Tree assembly can be tailored to fit most BOP stacks by adjusting the fluted hanger on the hanger mandrel. When the valve and latch assemblies are connected, their combined length is less than 6 feet, 10 inch. In most BOP stacks, that makes it possible to close the pipe rams on the slick joint and still have room to close the blind rams above the latch assembly.

Safety Training
During three months undergo my internship program at ACRE Port Klang, I have undergone several trainings and it were compulsory for all intern students and new hired employee. Without those training, I am not able to do any job in ACRE workshop. The trainings are NEST, SIPP and Subsea Introduction training.
1) New Employee Safety Training (NEST)
New Employee Safety Training (NEST) is a compulsory training for new hired and intern students. It was conducted by Schlumberger Malaysia HSE Specialist, Mr. Izazilullah. This training was held at Rohas building Kuala Lumpur on 3rd and 4th of July 2019. 23 standards, and Schlumberger policies were briefed in this training. From this training, it is clearly shows that Schlumberger practices a healthy work culture, where self-development, HSE and team building are very much embedded in the working environment here. Safety is always a priority in Schlumberger, and even before joining Schlumberger all employees have to undergo medical check-up. Several tests and trainings on safety, be it personal safety, IT security or first aid, are ensured to be educated to all employees upon joining the company. Schlumberger takes HSE very seriously as it does not only save our life, but also heightens the chance of achieving our objectives if the policies and standards are followed. As the world’s leading oilfield service company, Schlumberger has a lot of activities and operations on-going every single day. It is very crucial that the rules need to be well-structured to reduce the risk of all the operations. Schlumberger’s Quality, Health, Safety and Environmental Policy (QHSE) is focusing to improve skills in order to achieve zero HSE-related issue in the company.
2) Schlumberger Injury Prevention Program (SIPP)
Another training that I have undergo was the Schlumberger Injury Prevention Program (SIPP) course which is made compulsory to all employee. This course also conducted by HSE Specialist, Mr. Izazilullah. SIPP focuses on body control techniques and special techniques to give one more control in work in terms of power, balance and stability. Those techniques are body control techniques and special techniques.
Body Control Techniques:
1. Line of Strength
Orienting one’s feet in the direction of the force. Put one foot forward to increase strength and stability, helping to maintain control when handling and lifting.
2. Side Stepping
Use side stepping as one move across and over hazardous areas to prevent slips, trips and falls. It maintains stability by orienting one’s line of strength in the direction that one is moving.
3. Safe Working Zone
Adjusting one’s position & equipment to work in the green zone (near to body) for maximum strength and stability by keeping load close to oneself.
4. Smart grip
Using the strength fingers to activate large muscle groups to allow more power and stability in action.
5. Watch Your Head
Keeping center of gravity within one’s stance to prevent slips, trips and falls. It maximizes eye movement & minimizes head movement to maintain balance and stability.
6. Bracing and Spinal Alignment
Activate one’s core muscle to protect the spine and brace to increase stability and distribute forces away from the spine, ensuring spine is always in neutral position.
3) Commentary Task Assessment (CTA)
The Complementary Task Assessment (CTA) is an assessment conducted after SIPP. It is conducted by a certified trainer on the application of SIPP theories, which are line of strength, side stepping, safe working zone, smart grip, watch your head and bracing and spinal alignment. It is only after CTA one can perform practical task (e.g. Handling of tools) according to Schlumberger's policy. This system ensures all employees are working in a proper way in terms of body postures and ergonomics to minimize injuries and risk of accidents.
4) Quest Training
Schlumberger provides an online QHSE system, QUEST which lists the competency level of each employee through certifications. Furthermore, it is made compulsory that all employees should lodge 4 Observation/Intervention (O/I) or RIR per month, which accumulates 52 reports annually. These HSE reports serves as a constant reminder for one to be observant and constantly aware of the surrounding hazards and possible risk. This method has proved to lead to a decrement in accidents in Schlumberger globally. In enforcing and reminding the reporting system, the sign '52' is pasted all around the workshop.
Project on New Workshop Layout
Transform Subsea Workshop
On the first week I am doing my internship, I was informed that our segment just moved from another area in ACRE to a new area which is the current place. From my observation, the arrangement of the workshop was quite mess and this situation is not good for the tools. The arrangement on the tools on the floor may broke the thread or the sealing surface of the tools. This condition also has a high risk for employee to do maintenance activity since their leg may be stuck or pinch between the tools. Looking at this situation, my manager, Scott Thomson and I plan a new layout for the workshop. Based on my manager opinion, he wants the 5S Lean Philosophy to be implement for the workshop. So, Scott Thomson assigned me to this project which is to implement new layout for the workshop. Figure 26 and 27 show the condition of the workshop before we applied a new layout.
