April 2013Sander Geophysics (SGL) has just completed an airborne gravity and magnetic survey in Kenya over CAMAC Energy's onshore Lamu Basin Blocks L1B and L16. "I am pleased that we completed the acquisition of the airborne gravity and magnetic geophysical surveys in Kenya safely, on time, and under budget," said Senior Vice President of Exploration and Production Segun Omidele. Now that data acquisition is complete, SGL will commence the final data processing and interpretation to identify faults, basement structures and intra-sedimentary volcanic layers and/or intrusions. CAMAC will use SGL's interpretation to optimize the placement of their planned 2-D seismic lines. CAMAC Energy Inc.

February 2013CAMAC Energy Inc. announces it has an agreement with Sander Geophysics to fly an airborne gravity and magnetic geophysical survey in Kenya over Lamu Basin Blocks L1B and L16. The survey will encompass 12,197 square kilometres in Block L1B and 3,613 square kilometres in Block L16. The resulting data will aid in identifying faults, basement structures and intrusions optimizing CAMAC's placement of 2-D seismic lines and targeting areas of further interest. CAMAC Energy Inc.

February 2013IceBridge's new website for the science community has been launched. According to NASA, Operation IceBridge's science goals include using glacier ice thickness, basal topography and other geophysical processes to increase the understanding of ice sheet flow. Another focus involves furthering technology to improve surface elevation measurements, thus enhancing sea ice thickness data. Sander Geophysics' gravimeter (AIRGrav) is one of the sophisticated instruments employed on the IceBridge project. NASA uses the gravity data from AIRGrav to distinguish between water (less dense) and rock (more dense) below the ice, which is crucial for studying the calving and melting of glaciers.

February 2013Further study is done to understand the significance of the M5.8 August 23, 2011 Louisa County, VA earthquake and the role of the regional geology. In this area there is limited bedrock exposure and the earthquake hypocenter was about 6 km below the surface. The USGS commissioned Sander Geophysics to fly a high resolution magnetic, radiometric and gravity (AIRGrav) survey. The greatly improved geophysical data provides scientists with the ability to further identify the relevant geological structures and develop some insight regarding the trend of the earthquake.

January 2013Preliminary findings are revealed from an airborne gravity, magnetic and radiometric survey that Sander Geophysics flew for the USGS, over the August 23, 2011 Virginia earthquake zone (see SGL news July 2012 for information about the actual survey). In this article, a USGS scientist describes how she hopes this kind of survey can help to identify pre-existing weaknesses in the Earth's crust, explain the pattern of an earthquake through geologic structures, and outline areas that are more susceptible to aftershocks.
