(Society of Petroleum Geophysicists) and EAGE (European Association of Geophysicist and Engineers), PDPU, organised an introductory session on 26th august 2014 for the budding petroleum engineers of first year. The session received an overwhelming response. The attendees were keen to know about petroleum sector and were excited to plunge into this relatively obscure field of engineering.

The session began with an introduction on each chapter, their objectives, roles and the benefits that students can reap by being a part of each one of them. Students were given a brief introduction on fundamentals of Geology and petroleum science. Students were given hand specimens of rock for examining their features.

The session was interactive and the organisers were kept engaged by an inquisitive crowd. The questions ranged from prospects in petroleum industry to terms of membership of the chapters. The students were apprised of oil and gas industry. The session concluded with a Quiz focussing on basic elements of petroleum science and industry. The quiz had a preliminary and a final round. The winners were given free membership and the runner up team received accolades.

The students seemed so eager to join these chapters that there was a rush for registration after the session culminated. The committee wished everyone of a very successful career in petroleum academics and industry. We convey our sincere gratitude to all the stakeholders.

It is said that logging is the eye of Oil and Gas industry. The student chapters of SPG, EAGE, SEG and AAPG in PDPU organized Well Log Interpretation Workshop on 6th September in collaboration with Institute of Reservoir Studies (IRS) ONGC. The workshop received an overwhelming response with an attendance of more than 150 students of PDPU.

The event was graced by eminent Geophysicists and Geologists from ONGC IRS and faculties from PDPU. We were truly honored and privileged to have Mr. Rakesh Kumar Sharma, Executive Director and Head IRS ONGC. He was accompanied by

• Mr. Indrajit Dasgupta (Chief geologist)
• Mr. A. P. P. Singh (Dy. Supt. Geophysicist)
• Mr. Rajesh Kumar (Dy.General Manager)
• Mr. P. P. Deo (Dy. General Manager) (W)

The session began with a talk on Geo-cellular modeling by Mr. Indrajit Dasgupta. He talked about various parameters of static and dynamic modeling along with the assumptions involved in various models. The next talk was by Mr. A.P.P. Singh, Dy. SG (wells) and he presented on an Overview of Well Log Data Acquisition.

This encompassed history of logging and its evolution, role of logging in Oil and Gas industry. He detailed various logging techniques and tools used for open hole, cased hole and production logging. He explained working principles, elicited the parameters measured and mentioned the applications of electrical logs, porosity logs, formation structure logs, pressure logs, side wall coring, depth correlation logs, production logs and high tech logs ( DSI, Formation Imager, NMR and CHFR tools).

The entire session was highly interactive and the curiosity and inquisitiveness of students was appreciable. The experts from IRS were pleased to reply to queries from students and clarified their doubts. Mr. Singh continued on tirelessly and explained the importance of cement evaluation, perforation, plug setting, cutter, back off services, shaped charges.

He ended with a brief on importance of production logging and production logging tool string (telemetry cartridge, Gamma, CCl, Pressure, Hydro, Density, Temperature, centralizer and spinner). The seminar continued and the post-lunch session started with a very interesting talk on Formation Evaluations by Mr. Rajesh Kumar CG (Wells).

He spoke about fundamentals of well log interpretation and parameters calculated by using well logs. The properties that can be measured by logs are porosity, shaliness, density, water saturations etc. He reiterated the importance of calibration of tools which ensures good quality log data. He talked about effects of drilling mud, depth alignment, hole size, hole rugosity, barite effect, salinity and temperature on log data. He then talked about flow profile and casing/tubing caliper, etc. A test was conducted to check the abilities of students on well log interpretation and students were asked to calculate various parameters. The logs were tough to interpret but when they were discussed by experts the bstudents found the answers explicit and manner of explanation was lucid. Students in small groups discussed the answers and inferences with instructors.

Finally, Mr. P.P. Deo talked about petroliferous basins of India (Assam, Bombay, Cambay, Cauvery, Krishna Godavari, and Tripura Cachari) their properties, reserves and production history. As the scale changes so does the picture. He talked about vertical resolution and depth of investigation of logging tools. He also delved upon porosity and permeability variations in sandstones and limestones. He gave us the microscopic and macroscopic picture of reservoirs. He also delineated coring and reservoir characterization. He showed various images of cores and oil samples. The seminar breached all timelines and deadlines but neither the instructors nor the students lost energy and eagerness to learn and share their viewpoints. Mr. Deo ended the workshop on a philosophical note by and urged the students to imbibe and apply their knowledge as an “integrated whole”. The workshop concluded with final words of appreciation from Mr. P.P. Deo, Dr. Ashish Sarkar (Faculty at SPT) and Dr. Uttam K Bhui (Faculty at SPT). We convey our sincere gratitude to all the stakeholders for helping us organize a very successful workshop.

On March 31, 2015 SPG Student Chapter IIT Roorkee organised a guest lecture by Dr. Rakesh Walia at the Department of Earth Sciences, IIT Roorkee. The topic of the lecture was Broadband Seismic Data. Dr. Walia is at present Country Manager and MD of CGG India. He was accompanied by Mr. Hemant Kumar, Technical Business Development Manager-Asia Pacific, CGG. The lecture was attended by around 50 Geophysics students and was graced by presence of faculty members.

Mr. Walia began his lecture by introducing the basics of marine survey, ghosts and broadband seismic. In seismic exploration broadband refers to a wider band of frequencies being recorded than in conventional seismic exploration. In the marine case the conventional acquisition system is said to give a useable bandwidth of typically between 8-80 Hz, whereas broadband seismic systems claims to give useable frequencies from as low as 2Hz up to 200Hz or more for shallow targets.

The additional low frequencies provided by broadband data means that a low frequency model from the well is not required for inversion, resulting in more quantitative results and higher confidence away from the well locations. Broader bandwidths produce sharper wavelets without side lobes to provide high-resolution imaging of important shallow features such as thin beds and small sedimentary traps. Lower side of frequency spectrum, i.e., 2-10 Hz decreases side lobes of Ricker wavelet (source wavelet). No horizons are mapped if this frequency is missing. Higher side of spectrum enhances the spikiness of Ricker wavelet and thus enhances resolution power of thinner beds.

He further talked about deep towed curved streamer profile, which is optimised for each marine survey, to maximum bandwidth. The streamer is towed at variable depths ranging from 7.5m to 50m. This enables to capture frequencies down to as low as 2 Hz and reduces weather related noise thus extending the survey-operation window.

Curved streamer profile provides better compensation of ghost notch for 6-35 m. With broader bandwidth and strong low frequencies, the images of sub-surfaces are rich in details enhancing interpretation and reservoir characterisation. He further mentioned about usage of broad source, multi-level airgun arrays. With curved streamer and broad source, the data is almost fully free from ghost (both source and receiver), extending the bandwidth beyond 6 octaves. This technique offers broadest attainable frequency spectrum, the data is of superior S/N ratio with improvement in depth penetration and illumination enabling better seismic inversion, strategic drilling and completion decision reducing uncertainties.
