Drilling, completion software can be shared among users
Newly released PetrisWINDS DrillNET is an advanced drilling and completion engineering software framework that combines capabilities of Maurer drilling programs into one easy-to-use, integrated package that permits data to be captured, reused, and shared among users.
The software’s intuitive user interface and integrated database are coupled with context-sensitive help and a novel traffic light approach to check that all data are complete for a calculation. Output reports can be generated from the results, and the data exported to Microsoft Office products. Additionally, DrillNET is available in multiple languages, including English, Russian, Spanish, and Chinese, and can be configured for each user to allow the use of one language for the program operation and another one for report generation.
DrillNET allows a user to focus on the specific drilling program of interest and does not require that data for the entire well be present to run the calculations. It allows users to models various outcomes based upon variations in inputs using the intuitive user interface for quick assessments on potential program outcomes using data from drilling operations in real time.

New engine cylinder lubricating system
The pulse lubricating system (PLS) is a new, electronically controlled cylinder lubricating system to meet the demand for lower cylinder oil feed rates.
Developed for application in RTA and RT-flex low-speed marine diesel engines, it delivers reduced cylinder oil consumption without compromising piston-running reliability, the company says.
PLS helps make it possible to reduce the cylinder oil feed rate compared with the existing accumulator system through an improved distribution of cylinder lubricating oil to the cylinder liner, and the fully flexible, precise timing of oil delivery.
The guide feed rate for RTA and RT-flex engines equipped with PLS as original equipment is 0.7 g/kw-hr of cylinder lubricating oil. The system promises to deliver accurately metered, load-dependent volumes of lubricating oil to the cylinder liner running surface at the precise timing required. Electronic control helps ensure the accurate dosage and timing, with full flexibility in settings.
The cylinder lubricating oil is sprayed as a pulse of multiple jets on to the liner surface from a single row of lubricators arranged around the liner, each lubricator having a number of nozzle holes. The oil jet sprays ensure better distribution of the oil over the liner running surface than with the existing accumulator system, the firm points out. There is no atomization and no loss of lubricating oil to the scavenge air.
