Alphageo (India) Limited

1. Designing and preplanning of 2D /3D/4D/3C surveys

Surveys by Alphageo are designed to achieve the objectives at an optimum cost. The main highlights are as follows:

• Direction and the layout of the lines is also tuned to the objectives.
• Preplanning in terms of exclusion zones, inaccessible zones and methodology to cover the area beneath exclusion and inaccessible zone is laid down.
• The quality control criteria to achieve the objective are prescribed.
• The accuracy and the tolerance limit for topographic survey and other aspect of seismic survey are defined.

 2. Seismic data acquisition in 2D/3D/4D/3C

Alphageo offers the following services under this category:

• Seismic data processing of 2D /3D/4D/3C data
• Reprocessing
• Special processing including pre-stack imaging, AVO inversion, etc.

With ever increasing demand for petroleum exploration activity all around the world, especially in the developing nations, many countries are offering blocks for exploration. Further, many Indian companies have joined the fray. Alphageo has the potential to evaluate all the geological, geophysical, wire line, reservoir and drilling data available and offer appropriate recommendation about block bidding. The recommendation includes identifying the data gaps and designing a strategy for acquisition of the required data and the exploration strategy.

1. Structural and stratigraphic interpretation
2. Generation, evaluation and ranking of prospects
3. Evaluation of blocks for exploration
