As Saffānīyah Oil Fields, Saudi Arabia: WaterSeer Ten Unit WaterGrid Yield Forecast

Climate: In As Saffānīyah, the summers are long, sweltering, and arid; the winters are cool, dry, and windy; and it is mostly clear year-round. Over the course of the year, the temperature typically varies from 53°F to 106°F and is rarely below 47°F or above 109°F. 

The hot season lasts for 4.1 months, from May 24 to September 28, with an average daily high temperature above 98°F. The hottest day of the year is July 28, with an average high of 106°F and low of 88°F. The cool season lasts for 3.3 months, from December 1 to March 9, with an average daily high temperature below 74°F. The coldest day of the year is January 25, with an average low of 53°F and high of 66°F.

Global climate change forecasts temperature and humidity will gradually increase and will persist for longer seasonal periods in this region. Extreme temperatures and humidity around the Persian Gulf are likely to approach and at times exceed the threshold of human tolerance within this century.

Humidity: As Saffānīyah experiences significant seasonal variation in Relative Humidity. The muggier period of the year lasts for 6.0 months, from May 14 to November 15, during which time the comfort level is muggy, oppressive, or miserable at least 10% of the time. The muggiest day of the year is August 28, with muggy conditions 39% of the time. 

Offshore Humidity: Although temperatures off-shore are comparable to on-shore temperatures, Relative Humidity offshore is significantly higher for longer periods. 

As Saffānīyah Oil Field Estimated Yield: As Saffānīyah Oil Field coastal region has an excellent climate for WaterSeer WaterGrid deployment from April to September. Yield is substantial from October to March, but below the peak high yield months. 

The offshore humidity and the ambient air saturated vapor density are close to peak saturation and has much more water vapor per unit volume of air, significantly increasing yield yields, up to 30% higher on average. 

A 10-unit WaterGrid on-shore will generate 134 liters per day on average from October the March and over 290 liters per day from April to September. An off-shore WaterGrid will generate 140 liters per day from October the March and over 370 liters per day from April to September. 

WaterSeer Yield Curve: The WaterSeer yield curve is below. Yield is based on WaterSeer Sonoma model third party testing and trials under a wide variety of controlled and field conditions. Monthly yield is on the left vertical axis. The bottom horizontal axis is the average temperature. The Relative Humidity % (RN) is color coded in 10% increments.



Sources and Data: Weather data and models are derived from historical weather reports January 1, 1980 to December 31, 2016. Yield estimate is from Sonoma Yield Forecast Model. Data graphics are from and
