Geology has many different fields of study. One of which is petroleum geology. As geological engineering students, we need to enrich our knowledge and develop the quality of ourselves in order to confront the challenges such as regarding hydrocarbon exploration, particularly in the future. Today, the discoveries and new concepts about the earth pertaining to geology are growing. Geology has a variety objects, located on and below the earth’s surface. Due to objects located under the surface of the earth, the process of data retrieval, analysis, and interpretation is supported by tools, both hardware and software. One of the software that can help a geologist, primarily related to Well Bore Imaging (WBI), is Techlog software.
On February 14, 2014, AAPG SC ITB held an office trip to Schlumberger, Jakarta. There, some members of AAPG SC ITB attended workshop about Techlog, Schlumberger proprietary software based on windows which can be used to obtain any information about wellbore. The speaker at this workshop is one of the alumni of Geological Engineering ITB 2002, Jhonny, S.T., M.sc, who now works as a petrophysicist at Schlumberger Jakarta. Before the workshop started, we were guided to get around the Schlumberger office located in Wisma Mulia, Jakarta. There are a lot of ITB alumni who work in this office, such as from petroleum engineering graduates and geological engineering graduates.
At the beginning of the workshop, Jhonny gave an explanation about Schlumberger in general. Schlumberger is an Oil and Gas Field Service Company (OFS). OFS is a company that sells services to Oil Company (OC). OC is a company that organizes an exploration in one location, produces oil and gas, and has its own field. Oil Company contracts Oil and Gas Field Service Company on a particular function, such as drilling services and logging activities.
In carrying out its functions, Schlumberger develops a variety of software such as techlog software. By using techlog software platform, petrophysicists, geoscientists, and engineers, can undertake the interpretation of all wellbore data types such as cores, images, photos, and logs. These different disciplines also can access and enter the same data into the workflows together. Thereby, previous investments of data can be utilized effectively. Subsequently, Jhonny gave an explanation of basic things in techlog software. Such matters include techlog modules, techlog windows, and the data structure. Moreover, we were also given an explanation about the levels of saving the data in techlog and image processing with wizard. This image processing method encompass incinonmetry QC, speed correction, image creation pad, harmonization button, pad concotenation plus orientation, and LWD image preparation.
Related to these explanations, techlog software users can obtain various information such as dips in the borehole, view of Well Bore Imaging (contains information about fractures, bedding, and so forth), dip picking, and storing borehole breakout information. Additionally, users of techlog software not only can observe two points, the interpretation dip plots and can observe a walkout plot of fracture strike, but also can enter spatial plotting of data on Stereonet. Users can also observe a borehole breakout. Information and data obtained in the wellbores are generally complex and varied. These should be utilized very well. The techlog software platform provides new ways of visualizing the wellbore formation models. Moreover, this software also can improve the operational effectiveness.
The advancement of science and technology can improve the interpretation quality of a geologist. Our knowledge as geological engineering students must be constantly fortified. We need to hone our personal quality in order to face the global challenges of the future.
