LTIMindtree Petroleum Data Management Geoscientist Interview Questions and Answers

Fold taper refers to the change in thickness of a fold along its length, while migration apron is a sedimentary deposit formed at the base of a fold.

• Fold taper is the variation in thickness of a fold from its hinge to its limbs.

• It is caused by the differential shortening and thickening of rock layers during folding.

• Fold taper can be observed in geological structures such as anticlines and synclines.

• Migration apron is a...read more

The optimum depth in Assam & Assam-Arakan Basin varies depending on the specific location and geological factors.

• The optimum depth in Assam & Assam-Arakan Basin is determined by various factors such as the presence of hydrocarbon reservoirs, geological structures, and exploration data.

• Geoscientists analyze seismic data, well logs, and geological models to identify the most promising depths for oil and gas exploration.

• T...read more

The seismic processing sequences in a 3D seismic survey involve several steps to enhance the quality and interpretability of the data.

• Data acquisition: Collecting seismic data using an array of sensors or geophones.

• Field processing: Initial processing steps performed on-site to remove noise and correct for acquisition-related issues.

• Data preprocessing: Further processing steps performed in the office to enhance the dat...read more

Multiplex data refers to the process of combining multiple signals into a single signal, while demultiplex data refers to the process of separating a single signal into multiple signals.

• Multiplexing combines multiple signals into one, while demultiplexing separates one signal into multiple signals.

• Multiplexing is commonly used in telecommunications to transmit multiple signals over a single channel.

• Demultiplexing is th...read more

The header file in Seismic processing software contains metadata about the seismic data.

• The header file includes information such as acquisition parameters, processing history, and data quality.

• It is typically in a binary format and is read by the processing software to properly interpret the seismic data.

• Examples of header file formats include SEGY and SEG-D.

• The header file is essential for proper seismic data managem...read more
