Condition of the Macondo Well Before the Explosion
The condition of the Macondo well before the explosion continues to be a concern as the latest attempt to seal the well (Collar, Cap, and Collector) has not reached the desired PSI of 7,000. Rather the PSI has reached just … Continue reading

Subsidizing Renewables: Why this is important
The truth exposed by the BP oil spill is how damaging oil use can be for our environment and planet. It’s tough to see the impact of climate change because of its small, subtle changes over many years. Seeing wildlife … Continue reading

Relief Wells
Will the relief wells work? The problem is that there is another 2,000 foot well branching off from the current well. Will the new relief wells intersect the well below the first attempt and the second attempt? Or is it … Continue reading

BP Response
It would be great if BP’s response was a little more tech/web 2.0 friendly. Why aren’t they fostering the creative ideas from so many people with talented minds. Instead, submitters to the response form are sent to the following site … Continue reading
BP Pipe Into Reservoir: long string
What was BP thinking when they chose the unconventional single long pipe design into the reservoir? From the WSJ article The cement job was especially important on this well because of a BP design choice that some petroleum engineers call … Continue reading

BP Intended To Plug and Abandon Well Before Explosion
Prior to the BP oil well explosion on April 20, 2010, BP hired Halliburton (the cementing contractor) to plug the well and temporarily abandon it, a standard practice in the industry. Still, by mid-April, the well seemed a qualified success. … Continue reading

Latest Attempt: Collar, Cap, and Collector
Let’s hope that the new cap proves the well is solid and intact. If it proves that the well when capped is forcing the oil out of other parts of the broken BOP or into the seabed (below the seafloor) … Continue reading

New BP Cap Procedure
Here is the latest attempt to stop the flow of oil from the leaking well. Let’s hope it works. Once the new cap is installed tests will be performed to calculate the pressure of the oil flowing from the pipe. … Continue reading

Liquid Carbon Dioxide
Liquid carbon dioxide forms only at pressures above 5.1 atm; the triple point of carbon dioxide is about 518 kPa at -56.6 °C. The critical point is 7.38 MPa at 31.1 °C. Plumbers use equipment that forces pressurised liquid CO2 … Continue reading

Oil Freezing Temperature
Oil freezes -18 Celcius (motor oil), diesel -30 C, Cuide Oil -31 F (-35 C) Kind of temperatures you’ll get with dry ice (-78°C) or even liquid nitrogen (-196°C) Olive oil: 6C (refrigerator temp) Sunflower oil: 17C Aviation gasoline: -60C … Continue reading
Water Freezing Under Pressure
Water freezes at a temperature below 0 °C under a pressure higher than 1 atm (0.10 MPa). Consequently, water also remains frozen at a temperature above 0 °C under a pressure lower than 1 atm. The melting of ice under … Continue reading
Salt Water freezing temperatures
The freezing temperature of salt water depends on how much salt you put in. Oceanographers define the “salinity” of water as the number of grams of salt per 1000 grams of water. (Since 1000 grams of water is almost exactly … Continue reading

Density of Salt Water (Seawater)
The density of surface seawater ranges from about 1,020 to 1,029 kg•m−3, depending on the temperature and salinity. Deep in the ocean, under high pressure, seawater can reach a density of 1,050 kg•m−3 or higher.

Density of Dry Ice
The density of dry ice varies, but usually ranges between about 1.4 and 1.6 g/cm3 (87–100 lb/ft3). Dry Ice, solid C02 would therefore sink to the bottom in salt water.

Ice-crushing Strength
Maximum ice-crushing strengths averaged from about 475 lb/in2 at the White River near Oacoma/Presho site to about 950 lb/in2 at the James River at Huron site. See this pdf for additional information on the ice cores taken from South Dakota … Continue reading
