Multiphase pump extends production life
The Moyno Tri-Phaze System is a progressing cavity solution for multiphase pumping applications.

The system allows all fluids produced at the well site — including oil, water, and gas — to be transported

simultaneously through one pipeline to a central processing station. Its abrasion resistance allows for smooth transfer of sandy fluid. The unit is capable of generating flow rates up to 60,000 b/d of fluid with suction pressures up to 900 psi and discharge pressures to 1,200 psi. The Moyno Tri-Phaze System features a stator elastomer formulation that exhibits exceptional resistance to aromatics.

Additional advantages include:
• Gas void fraction handling up to 99%;
• Preservation of each fluid’s characteristics without emulsification or degradation through low-shear pumping action;
• Extended well production life; and
• Decreased well bore pressures.

Fracturing technique boosts production
The HiWAY flow-channel hydraulic fracturing technique improves the deliverability of hydrocarbons from the reservoir to the well bore by creating channels within the propped fracture. These open channels provide highly conductive paths for oil and gas to flow.

The conductivity of a conventional fracture is affected by several factors such as crushing, fines migration, residual fluid damage, multiphase flow, and non-Darcy effects. The HiWAY service mitigates these factors because proppant serves as a supporting agent to prevent closure within the channels, rather than as a conductive media, as in the case of conventional treatments. Fracture performance thus becomes independent of retained proppant pack conductivity. Also, the open channels extend from the near-wellbore area to the tip of the fracture, significantly increasing the effective fracture length.

Schlumberger reports that extensive field tests of the flow-channel hydraulic fracturing technique have shown increased flowback rates, improved polymer recoveries, decreased risk of screenout and proppant flowback, and substantial gains in hydrocarbon production and estimated ultimate recovery.

The channels are created within the proppant pack through a patented technique that combines a special pumping procedure, perforation scheme, and fiber technology. Over a two year period, wells treated with the HiWAY service have proven stability of flow channels and sustained hydrocarbon production.

Valve flow contour feature increases inflow area

version. The valve features a transitional flow contour that increases inflow area from inlet to outlet. The V150E is designed for installation directly to a medium consistency pump discharge flange. The single-piece body design has no gasket joints, which eliminates potential leak paths, and the expanded outlet will accommodate larger diameter transfer lines.

A critical part of the design is the segmented V-notch ball as the control element, which has a natural shearing action good for pulp stock or slurry flows.

This segmented V-notched ball also provides excellent rangeability and an unobstructed flow passage.

Streamlined drilling reporting tool unveiled
IDS, provider of Web-based reporting and analysis services to the upstream oil and gas industry, has unveiled DrillNet Junior. According to IDS, the new drilling reporting tool is a streamlined version of the company’s DrillNet application.

The aim of DrillNet Junior is to bring high-quality drilling reporting services to smaller operators. The original DrillNet and subsequently, DrillNet2, reporting software has been used by operators for many years to instantly recover and analyze data and documents, generate a fully customized daily drilling report, dozens of associated summary reports, and a final well report ready for distribution directly from the system. DrillNet Junior now allows the same information to be obtained, but with a more limited number of fixed reports and without the high level of customization usually provided by IDS. This “off-the-peg” version of DrillNet will deliver considerable cost savings, IDS said, and will allow operators that had been previously priced out of the market, to benefit from a comprehensive drilling reporting tool. www.idsdatanet.com
