Farzad-B Field is located in the southern part of the Persian Gulf. For this project, PSTM and PSDM were carried out using CRS method in a joint venture with TEECsolutions Company from Germany. The project covered an area of 150Km² where the main objective was to improve the quality of seismic data in depth domain for better understanding of the subsurface image and identification of the geo hazards involved. The project was assigned by POGC in 2018.

Paydar Field is located south of Dezful Embayment within the Zagros Mountains. The PSTM and PSDM processing, seismic interpretation and reservoir characterization of 2D seismic lines were performed in an area of 690 km. This was done in order to generate time and depth structural maps, pre- and post- stack seismic inversions and facies modeling for reservoir levels. The project was assigned by ICOFC in 2018.

This project included a full field study and MDP preparation for the availability and accessibility of feed gas for the three fields, where fault and horizon interpretations were reviewed for Zeloi (840 km²) and Qaleh-Nar (278 km²). In addition to this, seismic interpretation was performed for Karun Field (438 km²). The project was assigned by MISBP in 2018.

Susangerd Oil Field is located in the northern part of Dezful Embayment. One of the main objectives of this study was the 2D seismic interpretation (284 km) of the structure using the data of the neighboring wells in order to provide subsurface maps for the evaluation of the hydrocarbon potential and a better clarification of reservoirs extension. In addition, seismic inversion was another objective followed to better understand reservoir parameters, especially in spots of ambiguity. The project was assigned by National Iranian Oil Company (NIOC) in 2018.

Kish Gas Field is located in the central part of the Persian Gulf. The study aimed at structural seismic interpretation and reservoir characterization of the field using 1800 km of marine and land 2D seismic lines, as well as the drilled wells in the study area. The procedure involved picking horizons and faults in association with structural analysis of the field. Target horizons had been interpreted and their two way time and depth contour maps generated. Due to existence of two different vintages of seismic data with different characteristics (amplitude and phase spectrum), seismic inversion was performed on marine and land lines separately. The project was assigned by Pars Oil and Gas Company (POGC) in 2018.

Sarkhun Gas Field is located northeast of Bandar Abbas port city within the southeastern Zagros Fold and Thrust Belt (ZFTB). The geophysical study included re-processing, interpretation and seismic inversion of the existing 2D seismic data (410Km). The interpretation procedure involved generating time and depth underground contour maps of reservoirs in association with structural analysis of the field. Meanwhile, post stack seismic inversion was also conducted on Sarkhun seismic lines to extract reservoir parameters. The project was assigned by Iranian Central Oil Fields Company (ICOFC) in 2017.

Bankul and Babaghir gas fields are located north-east of Tang-e-Bijar Field in the west of Iran. The geophysical study of these fields included fault and horizon interpretations using seismic sections (totally 1000 km) as well as attribute maps. According to seismic inversion results, major stratigraphic units and lithology variations were defined as “generally well” in the inversion time gate. Consequently, a multi-attribute analysis was conducted to predict reservoir parameters using seismic data. The project was assigned by Natural Gas Storage Company (NIGC) in 2018.

Tang-e -Bijar Structure is located in the west of Iran (Ilam Province). The geophysical study was accomplished based on available 2D seismic data covering Tang-e-Bijar and its vicinity toward Bankul and Babaghir fields. Approximately 1670 km of 2D land seismic data processing of Tang-e-Bijar project included two main phases of seismic processing pre- and post-migration sequences within time and depth domains. Seismic interpretation was performed directly on the PSDM data with regard to PreSTM and PostSTM 2D seismic lines. Moreover, during seismic reservoir characterization, post-stack acoustic impedance inversion and attribute analyses were conducted on 680 km of Tang-e-Bijar seismic 2D lines. In the geological modeling and risk assessment section, two models were built. The two models provided very important input, not only for the volumetric, but also for the risk analysis of the identified prospects. They were produced using the existing well log data interpretations and the seismically derived depth maps and faults. The project was assigned by ICOFC in 2015.

This project was assigned to PPZG as a supervisory work in 2016. The geophysical study of Azar Field (located in the west of Iran) included the interpretation of several seismic horizons as well as generation of their time and depth structural maps. PPZG supervised all steps of the seismic interpretation including picking horizons and faults, generating time and depth maps, as well as preparing velocity models. The project was assigned by Petroleum Engineering and Development Company (PEDEC) in 2016.

A 3D seismic processing and interpretation on a small 3D land seismic data in order to image the subtle faults and fractures. In order to guarantee high vertical and horizontal resolution, the data were acquired with high density and sample rate of 250 micro second. De-noising and velocity analysis are really tough due to low signal to noise ratio.

Drilling of the Tunnel was stopped due to water flooding via faults. This was due to the fact that the area is located in High Zagros where the subsurface is complicated and as a result seismic imaging is really challenging.

In November 2015, PPZG was assigned to a joint project with Larego Co. from Russia after winning in a tender involving 4 other companies. The project covers 1700 km of 2D seismic lines. The processing will be done in conventional Post Stack Time Migration and also both Pre Stack Time (PSTM) and Pre Stack Depth Migration (PSDM).

Basic and detailed interpretation will be performed in order to interpret and generate depth maps for 10 horizons and prepare Post Stack Inversion, attribute analysis and fracture modeling.

3D static modeling, prospect evaluation and risk analysis will be done in order to provide the new well locations with their corresponding risks priorities.

Using 3D structural models or interpreted seismic volume to design wells can minimize well planning time and optimize well locations and trajectories. As a result, better drilling decisions can be made which will, in turn, reduce drilling risk. Similarly, integrating seismic time/depth maps attribute analysis/fault interpretation and seismic reservoir characterization will help in identifying the appropriate well path as well as optimal prospective drilling areas. This project has been supervised by IOOC since 2015.‎
