Resume: TOTAL Day on Well Site Geology in Petroleum Industry

 Uncategorized

Well Site Geologist..? What kind of job is it..? Alright, to know more about Well Site Geologist especially in petroleum industry AAPG SC ITB in cooperation with TOTAL E & P Indonesie (TEPI) held a Lecture with themed “ TOTAL Day on Well Site Geology in The Petroleum Industry” on May 10th 2014. This event began with welcoming speech from Mr. Nuki as advisor of AAPG SC ITB and Mrs. Moskwita Darmawan as a Human Resources in TEPI. There are three speakers in this event, the first is Mr. Ronald Atasi (Well Site Geologist TEPI) give a lecture about Wellsite Geology Overview. The second speaker is Mr. Riksa Pribadi (Petrophysics of TEPI) give lecture about Basic MWD/LWD Acquisition and Petrophysics Analysis and Coring. The third session is given by Mr.Lo Ten Haven (Geosciences Tutor of TEPI)  who talks about Mudlogging Case Study.

In Wellsite, geologist have important roles in maintain production of petroleum. A wellsite geologist tracks operations on the site of an oil or gas well to provide advice about how to conduct drilling. This person collects and analyzes samples of material taken from the well, advises personnel on site, and submits reports to geologists at the company’s headquarters. The wellsite geologist is also part of the health and safety monitoring team, advising people of safety risks so they can adjust their activities accordingly.

A Wellsites geologist, as the source of all operational geologic information, is the most important link in the chain of communication between wellsite and management. The importance of wellsite geologist to the overall successful termination of any project whose aim is to find hydrocarbon for exploration cannot be overstated. He is the exploration department’s man-on-the-spot upon whose shoulders rests the responsibility for obtaining (of insuring that) every possible scrap of information which can be wrested from the earth and insuring that the data are transmitted to the office in a concise butt comprehensive, coherent report. It is the wellsite geologist’s duty to confer regularly with the company’s wellsite drilling operations representative (company men) on location to forestall misunderstandings and to insure that the maximum information is obtained at the most economical price.

Wellsite geologists study rock cuttings from oil and gas wells to determine what rock formations are being drilled into and how drilling should proceed. They identify critical strata from core samples and rock-cutting data and build up knowledge of the structure being drilled. They are experienced geologists, deciding when specialized tests should be carried out and, ultimately, when to stop drilling. They send reports and logs of completed drilling to the operations geologist and offer geological advice to oil company representatives. Wellsite geologists also liaise with drilling engineers, petroleum engineers and mudloggers during the course of projects.

When an oil and gas company starts drilling in a given area, a wellsite geologist travels to the site to participate. They will review documentation from the period of oil and gas exploration, including results of surface testing. As the drill is sunk into the borehole, they analyzes samples of rock and mud. This information is used to construct a profile of the formation the company is drilling into. The geologist can provide advice about how and where to drill, and when to stop.

The wellsite geologist is in a good position to identify safety problems. If he sees issues of concern, such as hazardous substances in the samples, he should bring this up with the foreperson and other members of the drilling crew. The geologist offers technical advice on safely accessing the formation and controlling conditions on site to keep members of the crew safe, as well as protecting expensive drilling equipment.

A large amount of Geological data is acquired – as a substantial cost – during a drilling operation. Ensuring optimal quality of this information and effective reporting plays a key role during well design and drilling operations, as well as later use of this data in field studies. A key requirement for success is close cooperation between geological, drilling, and engineering departments.
