Oilfield Chemistry

Many of our remaining hydrocarbon resources are in deep, remote and complex reservoirs. To access these reserves, engineers must deal with cold subsea wellheads, high bottomhole temperatures and surface temperature extremes that challenge personnel, equipment and chemistry. Case histories from Siberia, the Middle East, the Gulf of Mexico and the North Sea demonstrate how new chemistries and engineering solutions are helping operators efficiently drill and produce the Earth’s remote hydrocarbon resources.

Producing Gas from Its Source

The success of the Barnett Shale gas play in north-central Texas, USA, is prompting operators to explore other basins for similar potential. However, their goal may be realized only under the right conditions—when geology is matched with infrastructure and technology sufficient to exploit and produce it.


Compaction and Subsidence

Compaction and Subsidence

Formation compaction not only provides drive pressure to produce hydrocarbons, but also can create problems in the formation and at wells in both the producing and overlying formations. At the surface, subsidence can lead to flooding in low-lying areas and platform safety problems offshore. This article examines practices to monitor and control compaction and subsidence and mitigate various effects in fields in the North Sea, The Netherlands and the Gulf of Mexico.

Improving Oilfield Service Efficiency

Worldwide demand for oil and gas is encouraging energy companies to stimulate production from declining fields and to develop new fields in remote locations. Operational efficiency is essential for either scenario to be economically feasible. This article describes efficiency improvements in two oilfield services—hydraulic fracturing and resistivity logging—and illustrates the associated economic benefits.
