... phases is degraded. Over the last few years, low-shear valves targeting petroleum processes have emerged on the market. This paper presents four separate live-fluid experiences from low-shear valve installations, each surveyed and documented by an independent third party. Three of the installations refer...

The panel on the left shows the heating before the supersonic nozzles were installed, and the panel on the right shows the heating 6 months after the installation of the nozzles. It is shown that the steam conformance was greatly enhanced for both wells after the installation. The economics...

... (Lochman and Bryce 1980 ; Yu 1995 ) and adapted for pumping multiphase mixtures from oil‐producing reservoirs. The pilot installation of this technology occurred in an onshore field, located northeast of Brazil. There is a brief description about some specificities of the progressive vortex pump (including...

This report presents a comprehensive review of AL system application with specific focus on tight oil and gas formations across the world. The review focuses on over 35 successful and unsuccessful field tests in the unconventional...

...C. N. Hardegree; B. A. Gerrard; S. L. Wildman; K. S. McKenzie Summary In this paper we highlight a pilot project in which chamber gas lift was installed in two unconventional horizontal wells. Chamber gas lift, a combination of deep gas lift and intermittent gas lift, allows for an efficient...

... since the start of production, this is not considered as the root cause of emulsion formation because the water cut remained unchanged at approximately 5.5% after the jet-pump installation. The fluid properties of oil and water from this well are summarized in Tables 3 and 4 . Table 3...

... and considerable installation/deployment costs because a workover rig is typically required for intervention. Unfavorable producing conditions and tortuous wellbore trajectories tend to further decrease run lives. These issues can make economical hydrocarbon production impossible. The SRVP was developed...

A two-stage design is presented, with two field installations in the Eagle Ford Shale reviewed as a case...

... of a self-installing platform (SIP). The platform is currently the largest of its kind in the world at 133 m high, being slightly heavier than the Eiffel Tower and designed for future reuse at another location for the purpose of producing some other small accumulation. The platform was installed...

...Abisoye Babajide; Jim Hall; Johnnie Garrett Summary When oil wells can no longer flow naturally at the desired rate, artificial-lift methods are often employed. Most mechanical installations of artificial-lift equipment require a complete workover of the well, involving pulling the well apart...

During the last 4 years, a second stage has been initiated, and the third phase will be finished by 2007. By then, Repsol-YPF will have installed 67 compressors in the field, including new...

.... Another aspect of oil-water separation investigated was the effect of processing equipment and vessel retrofitting. These included the conversion of two-phase (gas/liquid) separators into three-phase (gas/oil/water) separators, installation of coalescer packs, demulsifier injection strategies, and use...
