Your job is to bring new supplies on line, on time, and at acceptable cost. All while dealing with increased regulatory activity and environmental concerns, skilled worker shortages, remote locations, and geological complexity.
And today the industry is no longer operating XQGHU�D�%RRP�7RZQ�PHQWDOLW\³LW·V�FORVHU�WR�D�“factory” business model. That means dealing with tighter margins and less room for error. Also, the expansion of gas supply may mean that the price of natural gas will be in the low-to-modest range for years to come. That makes shaving costs of drilling and well completion operations even more critical.
The Product Must Flow... But at Minimal Cost

The key to maximizing the return on oil and gas development projects rests with the maintenance and safety of your—sometimes—aging equipment.
While most upstream organizations today use traditional maintenance models (see Fig 1.), companies using condition-based monitoring have experienced:• Production increases in the range of 5% overall• Increased reservoir life• Lowered cost of production��6LJQLÀFDQW�LPSURYHPHQWV�LQ�RSHUDWLRQV�� maintenance and decision making.1

Condition-based monitoring means detecting equipment problems before they lead to lost production. Companies employing this approach use “alarms” such as pressure transmitters to identify faults and spot patterns—and correct them before they affect production.
The next section will discuss how to select a pressure transmitter that can help ensure productive, cost-effective operations.

The oil & gas industry engages in what some have called: “Managed chaos.” Managing leaseholds and optimizing rigs across multiple basins is a major challenge. Changes in rig availability, rig rates, permit approvals, site access, and availability of consumables and services can happen overnight.
