Radio-frequency identification (RFID) offers the user flexibility in controlling downhole operations without intervention. RFID uses close-proximity sensing to communicate by simply passing a coded tag through an antenna-equipped downhole tool to actuate it.

This paper presents a new approach in monitoring the hydraulic system and in the recognition of well‑control events at an early stage such that proper counteractions can be initiated before any damage occurs.

This paper reports results of a well-control study for a program to develop a dual-gradient-drilling (DGD) system known as controlled mud pressure (CMP).

The development of the Kanowit field offshore Sarawak, Malaysia, requires the drilling of two subsea development wells with a semisubmersible rig.

Ferrous sulfide (FeS) precipitation increases during shale-gas and -oil production because of increased biologically and thermally induced sulfide production. Although FeS scale is abundant, little is understood about its precipitation and inhibition properties.

The gas-producing carbonate zones of the Ghawar field in eastern Saudi Arabia have been affected by extensive iron sulfide (FeS) scale deposition, reducing overall gas production and increasing risks during well interventions.

This paper describes various sulfide inhibitor-testing techniques that have been applied to candidate products for the management of zinc sulfide (ZnS) and lead sulfide (PbS) in a gas/condensate field with a known relatively severe ZnS/PbS scaling problem.

Critical to success is the accurate testing in the laboratory that best approximates field conditions.

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. He authored patents and pape…
