Project Management of Offshore Well Completions

Offshore wells, particularly those in deep water, have become a key source of oil and gas, and their importance will grow in the coming years. Overcoming the many challenges these wells present requires close cooperation between operators, service companies and manufacturers, especially during wellcompletion operations. This article presents two case histories that illustrate how an integrated approach can lead to successful results.

Optimal Fluid Systems for Perforating

Optimized perforating strategies comprise a number of key elements. Among these are tools and techniques for maximized perforating-gun performance, clean perforations and a properly engineered perforating fluid. Until recently, perforating fluids have been poorly researched and little understood. This article describes extensive research that shows how perforation efficiency can be dramatically improved when optimized perforating fluids are combined with overbalanced perforating techniques.

Reducing Exploration Risk

Recent improvements in seismic data acquisition and analysis are reducing the risk of drilling unsuccessful exploration and development wells. This article describes innovations in seismic illumination made possible by probing seismic targets from several angles, and discusses new vertically aligned configurations of sources and receivers that are increasing signal quality in hard-to-image areas. Examples from the Gulf of Mexico, West of Shetlands, and offshore Mexico show how improvements in seismic technology are reducing drilling risk.

The Expanding Scope of Well Testing

Operators have long relied on well test measurements of pressure and flow to quantify production. Over the years, increasingly sophisticated tools and testing strategies have been developed to further characterize the properties and performance of the well and beyond, into the reservoir. This article describes advances in downhole and surface testing equipment. Examples from the Middle East and the Gulf of Mexico demonstrate the improved reliability and performance offered by today’s well testing methods.

A Small World with Great Promise

Tiny microelectromechanical systems, or MEMS, are becoming an increasingly significant part of our everyday lives. MEMS characteristics as sensors and actuators make them attractive to the E&P industry. But can these small devices survive harsh oilfield environments? This article covers the basic theory underlying MEMS and MEMS manufacturing. It also discusses the advantages and disadvantages of MEMS and applications in the oil field.
