Drillstring vibration is a leading cause of downhole-tool failure and premature wear of downhole equipment.

Sourcing water for large multifracture stimulations in west Texas is a well-known constraint on oil and gas activities in the area. A 6-month pilot operation demonstrated that produced-water reuse is technically feasible and can be a cost-effective solution.

This paper summarizes the benefits of using a bipolymer crosslinking system in environments where water quality cannot be guaranteed. It also demonstrates the yielded cost savings per well that are achievable when reusing 100% produced or flowback water for hydraulic fracturing.

A new technique that analyzes scanning electron microscope (SEM) images of formation samples has been used to measure porosity and total organic carbon (TOC) in the Wolfcamp Shale of the Delaware Basin in west Texas.

Surplus production in the oil markets is likely to grow in 2017, and long-term oil prices will track with costs and not revert to the margin-inflated patterns of the shale boom.

The world’s developing countries will lead economic growth and consume an increasing share of energy production globally over the next quarter-century.

Iran’s national oil company is offering investment opportunities in 50 fields to global bidders, its first effort to do so since the 2015 pact with world powers that lifted nuclear-related sanctions against the country.

Drillpipe doesn’t last forever, but a ­Houston-area startup company says it has developed a way to make it last significantly longer.

The story of unconventional oil and gas technology development has been focused on fractures. The formula has been more stages, more sand, and more water, targeting the most productive spots.

A normal five-spot polymer-flooding pilot has been conducted at the Mangala field, one of the largest onshore fields in India, and results are encouraging
