The addition of a hydrocarbon condensate to steam operations in heavy-oil and bitumen reservoirs has emerged as a potential technology to improve not only oil recovery but also energy efficiency.

Chemical enhanced-oil-recovery methods such as polymer and alkaline/surfactant/polymer (ASP) flooding are generally not considered suitable for oil viscosities greater than 100 or 200 cp.

The integration of microseismic data with 3D seismic attributes, and well log and completions data is used to understand geomechanical rock properties.

There is no shortage of ideas for reducing the cost and risk of offshore oil and gas developments. The hard part is implementing them in an industry where they require changes in long-standing habits, corporate cultures, and some new technology.

Statoil is going to work to put its enormous Johan Sverdrup discovery into production, showing that even one of the most explored parts of the North Sea still has significant potential.

In a down market, plugging and abandoning North Sea wells looks like an opportunity. The cost for operators is reduced because the government is paying more than half of the cost of the work, and many service companies hungry for work are offering discounts.

In the interest of conservation and sustainability, it is highly desirable to maximize any opportunity to reuse the produced water for subsequent fracturing treatments.

This paper reports the completion of a two-lateral well in the Williston basin where produced water (PW), filtered but otherwise untreated, was used throughout the slickwater and crosslinked components of approximately 60 hydraulic-fracturing stages.

With the innovation of extended-reach and directional drilling, running casing and liner strings has become increasingly difficult.

While rotary-steerable systems (RSSs) dominate the offshore directional-drilling markets, the land-based markets are still dominated by conventional directional-drilling tools. This paper presents a new RSS that is being designed and tested specifically for the onshore markets.
