High Frequency Imaging in an Exploitation Production Environment - The Murzuq Basin, Case History Interpretation of high-resolution 3-D seismic imaging identifies subtle stratigraphic and structural changes that help in the placement of water injection wells and the development of new drilling opportunities in the Murzuq Basin, onshore Libya Case Study. Presented at the EAGE, Vienna, Austria, 12-15 June 2006.

4D Seismic provides quantitative data (Offshore, March 2006) Time-lapse seismic technique guides field management.

Finding what others missed (Hart's E&P, February 2006) Utilizing HFI™ and AVO on reprocessed seismic data in mature fields continues to be successful in identifying bypassed pay.

Seeing between a rock and a hard place (Hart's E&P, January 2006) Windows-based visualization of high-frequency seismic volumes optimizes reservoir potential in a channel play.

Change connections in the loop (Hart's E&P, September 2006) Until recently, processing stages have functioned in a self-contained manner. Now companies are connecting the dots.

Resolution Revolution Reaps Results (American Oil and Gas Reporter, October 2005) High resolution 3-D volumes of interpretable data with the proper spatial positioning have long been a goal of the oil and natural gas industry, and many techniques for achieving it have been developed through the years. Everything from newer acquisition techniques to methods for compensating for the absorption and dispersion effects that lower the frequency content of the data have been introduced and are now being used in production environments. This interesting development is part of a broader "resolution revolution" or the ongoing trend toward ever-higher data resolution and imaging clarity.

Houston's Computing Stature Likely to Grow (The Houston Chronicle, September 19, 2005) Geotrace is listed in top 10 supercomputers in Texas.

Enhanced 4D processing and quantitative analysis on Troll West using multiple vintages of legacy data (First Break, September 2005)

Gas-oil contact monitoring at Troll using high resolution 4D analysis and neural networks Presented at EAGE, Madrid, Spain, 13-16 June 2005.

Detailed 3D Seismic Interpretation Using HFI™ seismic Data, Fault Throw, and Stress Analysis for Fault Reactivation in the Cogollo Group, Lower Cretaceous, Urdaneta West Field, Maracaibo Basin As part of a reservoir modeling project, a detailed structural interpretation of 1150 km2 of HFI™ seismic volume was carried out. The number of normal faults substantially increased with this interpretation. The fault trend is related to the preferential flow direction of fluids in the reservoirs. Presented at the 2005 SPE Latin American and Caribbean Petroleum Engineering Conference held in Rio de Janeiro, Brazil, 22 June 2005.

Cluster Computing: CPU count isn't the whole story (The Leading Edge, October 2004) How to determine processing capacity.

Tracking Tertiary delta sands (Urdaneta West, Lake Maracaibo, Venezuela): An integrated seismic facies classification workflow (The Leading Edge, September 2004) This article illustrates a novel approach (based on seismic facies classification and 3D visualization) for tracking deltaic sand systems in the Urdaneta West producing field, Lake Maracaibo, Venezuela.

A new technology for HFI™ using Seismic Data comes to the North Sea Producing broader bandwith seismic data has always been a quest since exploration seismic was started in the 1930's. Since this time numerous algorithms have been written and tested and some are very effective in extending the useable spectrum in a data set.

2002

Curved-ray time migration can improve seismic imaging (Oil and Gas Journal, October 2002) Curved-ray prestack Kirchoff time migration is rapidly replacing other seismic time migration methods for focusing seismic images of subsurface structures.

Frequency-enhanced imaging of stratigraphically complex, thin-bed reservoirs: A case study from South Marsh Island Block 128 Field (The Leading Edge September 2002)

Pore Pressure Grows Exact, Important (The American Oil & Gas Reporter July 2002) In the continuing search for higher-quality subsurface information,companies are making use of new advances in resolution and accuracy of predicting subsurface pore pressure from seismic velocity data. Pore pressure data are important for inferring presence of a reservoir seal as well as potentially such velocity data.

Using a unique high-resolution imaging process to find pay (World Oil March 2002) Geotrace reprocessed an existing 3D survey over Lake Pelto Field then performed HFI™, Frequency Absorption Analysis and AVO. Cabot Oil & Gas used this data to discover substantial new pay that would otherwise have been bypassed in this very old field.

4D article Geotrace is one of the few contractors in the world to offer a proven and effective 4D seismic data processing capability. Unique technologies have been developed for use by the company's specialist processors. Millions of dollars of cost savings have already been gained from 4D processing by Geotrace.
