This module depends on the BCM2835 library that must be installed on your board before you can actually use this module. To initialize the sensor, you have to specify the sensor type and the GPIO pin where the sensor is connected to. It should work for DHT11, DHT22 and AM2302 sensors.
Profit comes from leasing these drill rigs at contracted day rates that exceed the company's cost of capital and operating costs. The offshore drilling companies are leveraged to long term price trends of oil. It is often stated that the break-even for deepwater drilling is oil over $70 a barrel.he reason it matters is because day rates and operating costs are vastly different. Day rates are typically $75,000 per day for jackups, and $400,000 or more a day for deepwater (rates vary widely, based on market conditions and rig availability).
Annual average electric rates and natural gas prices are used, which also helps to dampen cost variances. Gas lease equipment costs increased 8 percent in 2008 and decreased 4 percent in 2009. Gas lease operating costs increased 6 percent in 2008 followed by a 5 percent decrease in 2009.perating costs for the offshore Gulf of Mexico were estimated for 12- and 18-well fixed structure platforms. Maximum crude oil production was assumed to total 11,000 barrels of oil per day from each platform. Maximum associated gas production was assumed to be 40 million cubic feet of gas per day per platform.
