September 1998 ///

Special Focus

3-D visualization, automation speed interpretation workflow

Emerging technologies such as time-lapse 3-D (4-D) and multidisciplinary E&P software call for integration by geophysical workstation

4-D seismic simulation of a complex turbidite sand

Time-lapse seismic, well logs, static/ dynamic production data, reservoir and fluid-flow simulation are combined to analyze drainage patterns

A multisurvey 3-D prestack depth migration case history

Case history from a multi-survey project in the UK North Sea shows how overlapping surveys with different geometries were successfully merged

Fast track to success — an integrated approach

How a technical partner and a West Africa operator applied an integrated exploration program, from seismic acquisition to multiwell drilling

Interpretation of thin beds using stratal surfaces

Gulf of Mexico case history shows how extrapolating between two well-defined seismic surfaces can reveal important reservoir details

Features

Part 6 – Five completion scenarios are illustrated and discussed to show options designed to handle the field's highly unconsolidated reservoirs

Horizontal, underbalanced wells yield high rates in Colombia

Technical description of how a U.S. independent planned and drilled the country's first two horizontal wells using underbalance techniques

Multi-functional solid lubricant reduces friction/ prevents mud loss

Description of composition/ applications of resilient graphitic carbon (RGC) as a mud additive shows the new system's several advantages
