Wellsite Geology Training Course

Do you want to become a wellsite geologist? Are you looking for a lucrative career in oil and gas? Globat Oil and Gas Skills offers training in Wellsite Geology. 

Our wellsite geology course provides a comprehensive overview of wellsite operations from the wellsite geologist’s perspective. Our focus is on helping you understand all the job functions performed on the wellsite and how the data collated is used.

A large amount of geo-data is acquired during the drilling operation. Ensuring that the information is of optimal quality and effective reporting is crucial during drilling operations, well design and use of data in field studies. A requirement for success is co-operation between geological, well-engineering and drilling department. Wellsite geology is at the heart of it all.

Globat instructors will teach you all the techniques wellsite geologists use in formation evaluation. We use a combination of exercises and lectures. Upon completion of the course, you’ll have a deeper knowledge of the requirements of a wellsite geologist.

You’ll learn responsibilities regarding the well execution phase such as wireline logging, monitoring of coring, pore pressure evaluation and geosteering. Post-well duties include data distribution, end of well reporting and archiving.

Your trainers have over 20 years of experience in the oil and gas industry. We’ve pulled specialists such as data engineers, mudloggers, geologists and wellsite geologists. Globat trainers received training certifications from top institutions like Schlumberger and academic qualifications from the best universities around the world.

Who Is a Wellsite Geologist?

A wellsite geologist is an analytical role where geological interpretations are used to advise drilling personnel on the geological causes of problems that occur during drilling when fluids and drilling apparatus interact with rocks that form the borehole wall as well as to check the well meets geological targets.

Recognising geological problems early-on leads to cost-effective and rapid solutions that make the well safer and keeps drilling within budget.

In oil and gas extraction, a wellsite geologist supervises all the stages of the drilling process. A wellsite geologist studies and analyses rocks from oil and gas wells to direct drilling and identify rock formation where they are drilling. Knowledge of specialised test, wireline data, rock-cutting data, core samples and other measurement are required to analyse and properly evaluate the drilling process.

You’ll identify critical strata from rock-cutting data and core samples and develop knowledge of the structure being drilled.

As a wellsite geologist, you’ll liaise with drilling engineers and mudloggers to ensure drilling process is hitch-free and follows correct HSE procedures.

Ultimately, the burden lies on you to say when drilling should stop or be suspended. You’ll compile logs and reports of the drilling process and the final well report. You offer geological advice to representatives of the oil company.

Globat Skills equips you with top-notch critical and analytical skills, communication skills, supervisory skills and the leadership skills required to work well under pressure.
