New lithium cell suited for downhole use

The patent-pending MR125DD is a new primary lithium cell suited for oil and gas measurement-while-drilling (MWD) applications.

It is rated to a maximum temperature of 150° C. but operates most effectively between 75° and 125° C. The cell is an addition to the Moderate Rate family of products and is available in “DD” form factor.

For those users who cannot specifically affirm a maximum operating temperature, this firm’s DDMR150 cell, rated to 150° C., is available. The company says the 150’s lithium thionyl chloride chemistry offers great capacity when operating in the upper temperature range of 125° to 150° C. However, for those applications operating below 125° C., this new cell technology is suitable.

The 125° C. cell provides 33% more capacity in conditions below 125° C. at higher discharge rates than traditional industry standard lithium cells rated to 150° C., the company says. In addition, the MR125DD has greater retained capacity after prolonged exposure at higher temperatures, the firm points out. Although optimal between 75° and 125° C., this new product will operate safely in conditions up to 150° C. The 125° C. cell also delivers exceptional pulse characteristics, the firm notes. This new cell is suited for an array of oil and gas applications including MWD, logging-while-drilling, and pressure measurement.

Flow computer measures gas, liquids

The AutoEXEC multirun flow computer and remote telemetry unit now integrates measurement and control functionality for natural gas and petroleum liquids applications.

The AutoEXEC enables users to standardize and consolidate measurement applications on as many as 32 runs with one unit. It provides the speed and accuracy required for a number of applications, including custody transfer, the firm notes.

The unit has an update rate of 10 times per second and incorporates built-in API Ch 21.2 compliance for electronic liquid flow measurement along with API Ch 21.1 compliance for electronic gas flow measurement. In addition, the unit is easy to install with no required programming, and it is simple to operate and secure with assigned user access levels for retrieval of stored or polled data.

Built on a high performance 32-bit processor, the AutoEXEC runs at more than 300 million instructions per second while consuming minimal power. Scalable input-output gives users the flexibility to build a customized system.

USB connectivity enables users to connect a flash drive, laptop, PC, or printer. NEMA 4X enclosure enables installation onshore or offshore.
