New 4.75 in. resistivity MWD tool

Delivery of the new 4.75 in. Compact Propagation Resistivity (CPR) tool to the drilling industry is under way.

The maker says the tool will help expand the availability of measurement while drilling resistivity measurements by lowering the costs of this service. MWD service providers can improve utilization of existing rig site resources by providing this additional service.

The CPR incorporates technology that allows the tool to be made shorter than other devices without sacrifice in measurement quality, the firm says.

The tool was designed to provide state of the art resistivity measurements with the lowest possible cost of ownership, the company notes. By avoiding third party license fees, users can provide formation evaluation services at the lowest possible cost. Manufacturing costs are lowered by keeping the tool as short as possible, with fewer antennas than equivalent competing designs, the firm adds.

The CPR provides three transmitter-receiver spacings using two transmitter and three receiver antennas and operates at two frequencies. The tool is available in 4.75 in., 6.75 in., and 8.25 in. collar sizes to support a variety of drilling requirements and is rated for 175° C. and 20,000 psi bottomhole environments.

The first CPR collars were designed to integrate with existing customer MWD equipment. In this application, the customer's MWD system is retrievable and utilizes a mud pulse telemetry system at the top of the MWD probe as well as electromagnetic telemetry.

The modular design of the CPR allows the resistivity measurement to be adapted easily to a variety of existing MWD systems, including configurations with the mud pulse telemetry system at the bottom.

Batteries for the CPR are housed in the resistivity collar, simplifying the interface design to existing customer equipment. Directional, natural gamma ray, pressure, and other sensors as well as a mud pulse telemetry system can be added to the resistivity collar, to create an all-in-one solution for drilling and formation evaluation measurements.

New brochure on oil field lab report range

A new product brochure, yours free for the asking, discusses AC SIMDIS solutions.

SIMDIS solutions determine the true boiling point distribution of naphtha up to crude oil samples. The product range includes a fast application that reports boiling point data of jet fuel and diesel in 3-4 min. The automated applications provide fast and accurate data that meet and exceed the reproducibility of the worldwide standard test methods, the firm says.

Systems are available using an Agilent Technologies Inc., Palo Alto, Calif., gas chromatograph and are controlled by dedicated application software. The software package automates all aspects of calibration, validation, and sample analysis up to data reporting.

New whipstock system

The new WindowMaster G2 whipstock system is a premium casing exit version that combines one-trip capability of the WindowMaster whipstock system with a full drift window mill.

The company says that operators can save rig time with the G2. The system's full drift window mill requires less rathole to be drilled. The G2 can start, mill, and ream a window without requiring a change in the bottomhole assembly. In one trip, the G2 can be run in hole, oriented to the new hole direction, and anchored in place to mill a window completely. This eliminates at least two round trips with drill pipe that would be required with other window cutting systems, the company says.

The G2 uses Metal Muncher technology to mill a window quickly and efficiently without sacrificing window quality and with minimum weight and torque on the work string. The resulting cuttings are small and easily circulated out of the hole.

For use in hard formations, the G2 is compatible with the PathMAKER formation mill.

High-flow option added to ball valve family

A 25 mm version has been added to the high-performance Hi Pro instrumentation ball valve family.

Featuring a two-piece construction that helps reduce potential leak paths to a minimum, and a design optimized for reliability, the new valve is suited for long life cycle applications offshore.

The new high flow rate option extends the application scope for the valve family from instrumentation applications into areas such as isolation on process lines, and vessel draining and venting. The ability to specify the valve with a choice of end connections including integral compression tube fittings also suits it for hydraulic power applications.

The new, fully bidirectional Hi Pro valve is initially available in 316 or duplex steel; further fabrication material options will follow.

The design conforms to ANSI/ASME ratings and features a 4:1 pressure boundary safety factor, to deliver ANSI Class 1500 operation. It meets the fire safe requirements of API 607 and BS6755 Part 2. The valve's body end connector thread is additionally fitted with an environmental seal, protecting it from external corrosion attack.

The valve mechanism works on the floating ball principle, with dynamic response seats and an antiblowout stem, and offers 100% bubbletight operation. Valves are provided with PTFE seats for operation over –54° to +204° C. (–65° to +400° F.). PEEK seat material can be specified to allow the valve to operate over a temperature range of –54° to +232° C./–65° to +450° F.
