Storing Natural Gas Underground

Underground storage of natural gas is a growing industry that helps gas suppliers meet fluctuating demand. This article reviews the basics of under-ground gas storage and describes the technologies that make it possible, including mechanical modeling, salt-solution mining, horizontal-well construction, imaging while drilling, specialized completions and reservoir monitoring. Case studies demonstrate how these technologies are used to help in the design, construction and surveillance of underground gas-storage facilities.

Networking with the World

Sharing information globally in a secure network is vital for timely business decisions. In the oil and gas sector, that network has to extend to remote oceans, rain forests and deserts. With the diverse, globally dispersed workforce of many companies, the system must provide a variety of tools to maintain productivity, from self-healing software to help desks operated every hour of every day. This article describes a suite of services designed to maintain a secure infrastructure for information technology.

Combined Stimulation and Sand Control

Tip-screenout fracturing and gravel packing in a single operation mitigate sand influx without restricting well production. This “fracpacking” technique breaks through formation damage and minimizes productivity restrictions that plague cased-hole gravel packs. We review the evolution of this method, which gained wide acceptance in the 1990s. Case histories illustrate job designs, treatment execution, downhole equipment, fluid and proppant selection, pretreatment evaluation, applications and emerging techniques.


Seismic Applications Throughout the Life of the Reservoir

eismic Applications

Seismic images are no longer just for exploration. Operating companies rely on seismic data to help delineate reserves, avoid drilling hazards, position development wells, map porosity and other reservoir properties, monitor subsidence and track fluid changes. New acquisition and processing techniques have led to an increasing number of successful reservoir applications. Field examples in this article demonstrate the power of seismic data to reduce risk and enhance asset value at every stage of reservoir life.
