Opposed to when it was actually dying in 2001?
And KSA, which has already been pumping water into Ghawar to keep the oil flowing, has now started a CO2 injection program to try to keep the production rate up.

Yes, the oil is pretty wet when you're getting up to a 98% water cut.
In other words, the mere fact that the Saudis are trying a CO2 EOR pilot project suggests the Saudis are looking for some way to enhance production of the remaining oil at Ghawar.
Saudis now testing out CO2 EOR at Ghawar----the last phase of oil recovery is imminent

It is 40% water cut now as it has been for the number of years according to Aramco.

which says absolutely nothing about where they are now.

they would have 30 - 40 years of production left to get to the 70% ultimate recovery.

That may have been true years ago, but some parts of the field evidently have much higher water cuts now. The 2015 article from the Journal of Petroleum Technology (JPT) I cite in my post above says the EOR pilot program is being done in an area with a 98% water cut
Actually it does. It says they are at a point where they feel they need to test an EOR program that might help them maintain future oil recovery and also deal with their greenhouse gas requirements through sequestration
One estimate is that will ca. $50 bbl to produce oil from Ghawar using EOR. Thats a dramatic increase from today.
You are misinterpreting what is being done.
The fact that Aramco is undertaking a pilot project to test the efficacy of CO2 EOR at Ghawar means Aramco wants to know if CO2 EOR will help them maintain production at Ghawar.
Why else would they initiate such an expensive multi-year pilot project? For the fun of it?
Saudi Aramco has designed and implemented the first CO2-EOR demonstration project in one of the fields. It is worth mentioning that while Saudi Aramco does not require EOR oil for decades to come, this project is being pursued primarily to demonstrate the feasibility of sequestering CO2 through EOR in the Kingdom and using it as grounds to test new monitoring and surveillance (M&S) techniques.

Twelve major shareholders in U.S. shale-oil-and-gas producers met this September in a Midtown Manhattan high-rise with a view of Times Square to discuss a common goal, getting those frackers to make money for a change.
Good luck with that.
saudi..... to increase carbon sequestration and hence aid in their commitments regarding reducing greenhouse gas impacts..
Again you are posting utter nonsense---once again you've posted something that is the exact opposite of the facts.
Being the largest of its kind in the Middle East, Saudi Aramco’s first carbon capture and enhanced oil recovery pilot project demonstrates commitment to environmental stewardship.
"This breakthrough initiative demonstrates that we, as an industry leader, are part of the solution to proactively address global environmental challenges," said Amin H. Nasser, acting president and CEO. "Saudi Aramco is carrying out extensive research to enable us to lower our carbon footprint while continuing to supply the energy the world needs."
Led by the Saudi Aramco’s EXPEC-Advanced Research Center, the company’s Carbon Management Technology Road Map includes many focus areas with a main goal of developing the required technologies to reduce CO2 emissions.
Reducing gas flaring, introducing zero-discharge technologies at well sites, and implementing a comprehensive water conservation policy at all plants and communities are among the company’s environmental protection efforts.
Environmental stewardship has long been a hallmark of Saudi Aramco’s business, with the company’s environmental protection policy formally established in 1963 and its Master Gas System, which significantly reduced CO2 emissions, in the 1970s.
The pilot project is the latest in the company’s list of efforts, injecting 800,000 tons of CO2 every year into flooded oil reservoirs. A monitoring system is in place to measure how much of that CO2 remains sequestered underground.
As part of Saudi Aramco's environmental stewardship program (Al-Meshari et al. 2014), the company has recently embarked on its first carbon capture, utilization and storage (CCUS) through a CO2-EOR demonstration project in one of its carbonate reservoirs. It is part of a multi-pronged effort involving the company's strategic carbon management program aimed at finding technological solution to reduce CO2 emissions. It must be emphasized that Saudi Aramco does not require EOR oil at a production level for decades to come, this project is being pursued primarily to demonstrate the feasibility of sequestering CO2 via EOR in the Kingdom.
Here's a helpful suggestion: There must something you actually know a little bit about----try posting about something you know about instead of just making things up and posting nonsense about things you don't know about.

Aramco has always been on the fore front of oil and gas field innovation. They basically invented the MRC wells, one of the first to fully utilize SMART completions and downhole shutoffs along with expandable liners and the first to build a fully functioning Intelligent Field where drilling, production etc are all linked digitally to their full field models. They test things to improve recovery efficiency all the time, CO2 injection is just one that you have heard about, there are a host of others that may or may not be deployed at some point. There is no rule that EOR projects are undertaken at the end of a fields normal depletion, in many cases it is instituted quite early in the history to help improve overall recovery.
tita wrote: When the "peak oil" subject was mainstream in 2005, one of the main argument was about Ghawar field entering fast depletion, due to EOR techniques used to increase the rate, but advance the date of the peak. 12 years have passed, no sign of depletion... more a plateau.
tita wrote: So, calling for a depletion because they are testing other kind of EOR techniques is probably doomed to be wrong again.
tita wrote:Thinking that Ghawar can sustain its rate for decades is probably wrong also. Who knows? We don't have enough data to make anything else than wild guess.
