Mixed carbonate-/sulfide-scale problems have been reported when water is produced from carbonate reservoirs. This study presents interactions of lead sulfide and zinc sulfide coprecipitating with calcite.

James Lee Rike, SPE, of Tickfaw, Louisiana, died on 3 August 2014. He was 87. An SPE member since 1949, Rike played a key role in the development of new completion concepts, directional perforators, sand control using plastics, coiled tubing rigs, concentric tubing workover/completion operations, and advanced offshore completion practices.

"Smart water" is needed for effective waterflooding in carbonate reservoirs. A novel water-ionic technology, comprising nanofiltration and reverse-osmosis membrane-based processes, was identified for optimization in this study.

One of the earliest problems that plagued downhole fiber-optic technology is known as hydrogen darkening.

The human mind, presented with a series of time data, will generally look for common features, label them as events, and seek correlations against other timelines. This approach is fallible because questionable data might be selected in attempting to find supporting evidence for a perceived pattern.

Every year, JPT surveys its readership to help determine future coverage and to ensure that it is fulfilling its mission.

Safety, efficiency, and accuracy are fundamental goals of well construction. But as the search for new oil and gas resources pushes into deeper waters and increasingly complex reservoirs, meeting these goals has become more challenging.
