Description

​

SONANGOL, Angola's national oil company, conducted a 2D seismic acquisition project in the Namibe basin, in southern Angola.

 

The project is consisting of 8500 square kilometers of varied terrain types, ranging from high mountains to the highest dunes in the world, mostly remote from population centers.

 

The project, as other oil & gas research studies, consists of many activities performed by multiple companies from different countries. Therefore, MDVIA's services were required from the early stage of scouting to the seismic acquisition process.

 

From the first phase of the project to the end of the operation MEDVA GIS has operated INSIGHT (former name IMBONDIERO GIS) as the project's geographical Database. INSIGHT operated as a collecting data and reporting system and still serves as the project's unique GIS and database.

 

The data:

 

Scouting Operations

 

MDVIA has used its extensive field experience and knowledge to conduct scouting trips in complicated and challenging terrains. The geographically referenced data collected includes unique access roads, terrain type's analysis, population data, environmental issues etc.

 

Orthophoto Production

​

Aerial photography of the entire project area, at 40 cm. per pixel, was performed using light airplane equipped with the advanced Nevo system, using a 60 megapixel digital camera. The orthophoto map and 3D data produced in the process serve as an ultimate terrain visualization tool, used for terrain analysis, planning of seismic lines and field operations and as an accurate and updated base for producing other information layers.

 

Geographic Information System - INSIGHT G.I.S

​

Based on its rich experience with previous seismic projects, MDVIA has rapidly and efficiently created a complete GIS system for the project's management and participants.

 

The GIS service, based on a complex and constantly improved data base, includes a uniquely designed web environment GIS, which allows the user to view, analyze and download project data, regardless of geographic location.
