Enhanced Oil Recovery, Secondary, and Tertiary Recovery

May 1, 2018


Did you know that much of the oil in the ground is still present after primary recovery? In the kings english, that means there is still a lot of oil left in a well even after 10 years of pumping. The reason oil production slows is that the natural drive that once pushed oil aggressively towards the wellbore has subsided. Normally, the natural drive is either water or gas in the formation. In this article, we look to explain some of the common enhanced or secondary / tertiary methods of oil recovery.

With oil hitting new highs every day, it is clear the cost benefit of utilizing technology to get at extra production makes sense. When oil was in the $ 10-20 range, the incremental cost of some enhanced oil recovery methods did not make economic sense.

One of the most common secondary recovery methods is a waterflood. Essentially, a waterflood is a reintroduction of water into the formation to create a drive to push more oil towards the wellbore. To increase the efficiency of a waterflood, new methods utilize Alkaline-Surfactant-Polymer floods and some explorers are introducing microbes into the wellbore to increase the sweep efficiency of the flood, both methods have been met with success.

One method I find very interesting and have used with success on one oil well is the radial jet enhancement. The technology utilizes jets of high water pressure to cut laterally into the formation up to nearly 300 feet. The technology can be viewed at http://www.wellenhancementservices.com , ask for Steve Bowen if you are interested in utilizing the technology on some of your new or old wells.

With 80% of the oil still in the ground after primary recovery, there is still plenty of meat on the bone for utilizing EOR. New technologies are constantly being tested and will lead to greater gains in the future. One area I am very interested in is new drilling technology. The rotary drilling rig has not changed radically in 100 years, but new advances are coming and we'll discuss those in future blogs.

    I love your videos! They have been so helpful to me in my recovery from my second (hopefully last) relapse! Can you PLEASE do a step by step of how you make your tea…what ingredients you use etc.? I am American, so we don't do much tea here, at least not properly haha (coffee is the default) 🙂

    it takes literally only a sec until the ED thoughts come in when we start make meals an ear food. we need to react on what our bodies need before that even if its super difficult!! working on weight gain itself is already difficult because we gotta eat more and we gotta challenge ourselves to conquer our fear foods. doing it under restriction regardless how subtle it is makes it harder for us to accept our weight gain and be willing to continue our journey. It will make us physically recover but our fears will remain, and we will end up with freakin' quasi recovery!!!! We will gain weight anyway so why not eat whatever we want focusing on our better future! That is my opinion as a person who experienced quasi recovery for multiple times! Thank you for sharing this Meg!! I love your attitude toward your recovery journey💘

    like you mentioned, "diet" culture is so upsetting, and hard to challenge in recovery. I struggle with that myself.

  • Sheela Narayanan May 1, 2018 at 5:19 pm

    i did want to ask your opinion on the 'rules' and restrictions, do you recommend tackling them one by one? i feel like i make success when i focus on one at a time, rather than wake up one day and say 'absolutely no restrictions and today i will let go of every single rule/fear!' ideally this woul happen, but it does seem to take time.

  • Sheela Narayanan May 1, 2018 at 5:19 pm

    I'm so glad you made this video! love what you share so much. =) that jif jar is so cute! i haven't seen that smaller size. I am really glad you touched on this topic of restriction and not feeling guilt at all. I felt bad today because I definitely had nearly the whole jar, and peanut butter its the hardest food for me because i pretty much always binge on it. but i know that's just my body craving what it needs, and i'm surprised in recovery we actually NEED soooo many calories to rebuild ourselves. i'd like t obe able to have peanut or almond butter without all the guilt, still having to work on this!

    Not sure if you've already answered this but what are your thoughts on making/having friends who also have eating disorders? xx

  • Anonymous May 1, 2018 at 5:19 pm

    Thank you so much for this! I hit "healthy" bmi two weeks ago but I still feel starving and it scares me but I'm proud to say I've pushed through and kept eating normally 🤗

  • Lucy May 1, 2018 at 5:19 pm

    YAAAASSS!!! Spot on as always! Seriously, your videos help soooo much! Yes, we need to burst our ED bubbles!!!! Pop them away to be free!!! Lots of love as always to you Meg xxx

  • Tangerinka410 May 1, 2018 at 5:19 pm

    That was in a long time one of the most eye-opening videos, really touching my raw nerve!! Recovering from ED, I always make myself think that I am recovered..it even seems to others that I am completely like them. But I know deep in my mind that I DO have those sneaky habits..I know if calories didn't exist, how much more I would eat. Damn. I have to break free, somehow, from the fear of weight gain…

  • Camille Lena May 1, 2018 at 5:19 pm

    The other day I weighed myself…which I knew wasn’t a good idea, but I was curious to see where I was at. Weird things is that I’ve lost weight. I feel like I’ve been eating more so I’m not sure how that happened. Then of course my thoughts were split between I’m a failure and yes you lost more weight! Did this ever happen to you?

  • Karolina Gorkiewicz May 1, 2018 at 5:19 pm

    what do u you use to recording your vlogs and program to edit ?

  • Emma Stone May 1, 2018 at 5:19 pm

    Megsy, thanks so much for speaking about eating lots during recovery. I have been following some people who are so anti 'binge' when in recovery, and they think of it as a weakness, or another bad habit or that they will never stop. If you could do a full dedicated video about your experience with the amount of food you ate at the beginning of your recovery, like the muffins and Starbuck drinks, and how you felt I think it would be enormously helpful to these persons who are recovering but still are very restrictive and controlled in their recovery. Love your channel, you are such a inspiration.

    THANK YOU for what you said about PB. I always eat the same kind as you, and I do think it is restrictive when people say that you should go for the one that has as few ingredients as possible. It also sets you up for later dilemmas– what if the only PB available is the regular kind (which is often the case)? You won't feel comfortable eating it. And then, does this mean you have to eat the healthiest version of everything? The logic is not conducive to freedom, and it's important to at least show yourself, for a long while, that you can eat the more "processed" or whatever you want to call it version and that it's ok. If you really then decide you like the natural PB that separates and tastes like nothing, then go for it. But then it is more likely based on preference, not out of fear.

  • Christine May 1, 2018 at 5:19 pm

    How many calories do you try to hit each day? Do you follow minnie maud guidelines?

  • Joy Cooper May 1, 2018 at 5:19 pm

    YES! There is a reason they sweeten PB or add oil-because it is tasty and is way more creamy. I feel like I progress in recovery and then the messages from the “health” media and doctors kick in and I take steps back. I rely on the recovery community and videos like yours to keep my perspective. I find that I’ll “eat and eat” when I’m still restricting certain food groups-as in I’m eating more calories but still not balanced-incorporating all foods shuts off that message that I want more and more. I never thought that would happen. The crazy part of anorexia is I’ll go right back to what I was doing even though I know what I know. You look great in that orange color! That’s a beautiful top!

  • Maren Gray May 1, 2018 at 5:19 pm

    Eating my pb and watching this😂😂always love your chats..thanx for motivating me😊😊😊

  • Juibelly May 1, 2018 at 5:19 pm

    I can eat what I want until I gain weight. The moment I realise I gained weight (or when I got back my period for 2 days) I panick and just jump back to not eating enough. Even though I know it's my ed voice, I just don't want to have that body

  • Vegas Babe May 1, 2018 at 5:19 pm

    I hate the concept of a "maintenance diet". It makes me really scared of hitting my "goal weight" because it means that I'll have to restrict again to maintain it. So I completely agree with you, there shouldn't be such thing as a maintenance diet at all!

  • Kim Hoeltje May 1, 2018 at 5:19 pm

    It really doesn’t get much better than Jif!!!!! Those low sugar no salt added ones don’t even come close!!!!

  • Shannon Priestley May 1, 2018 at 5:19 pm

    This helped me so much!!! 💗💗💗

  • Madeline Wilson May 1, 2018 at 5:19 pm

    You see, right now in my recovery I'm only eating safe foods that are a normal amount of calories. But I'm not challenging myself to eat anything else. It's so hard because I don't know how to challenge this fear. But to be honest I'm just happy to be eating anything and staying alive. But I don't know how to challenge anorexic thoughts on introducing new 'scary' foods into my life again

  • Its JustArapo May 1, 2018 at 5:19 pm

    Are you weight restored?

  • Marguerite May 1, 2018 at 5:19 pm

    I actually have been super lucky in my recovery because my doctor knows if I'm restricting or holding back in any way just by looking at my face and attitude. Even if I gained weight, she immediately knows when I'm struggling, kind of amazing 😉 thank you for this video, very interesting!!

  • Tamara May 1, 2018 at 5:19 pm

    Do you still have 3 snacks a day?xx

  • RML May 1, 2018 at 5:19 pm

    Loved this video! Thank you Megsy! Your words are so motivational and inspiring! Wished your channel had millions of subscribers! This is the kind of content that really edify society!

  • Samantha Meneilly May 1, 2018 at 5:19 pm

    THIS IS EVERYTHING!! Seriously, I wish that everybody – be it someone who struggles with an eating disorder, disordered eating, "chronic dieting," etc. – could hear this and what you have to say because you express SO so many incredible truths. So much of what you speak about regarding the different forms that restriction comes in is something I can relate to, and honestly its a huge wake up call and tough love kind of thing to realize that yea, I can choose to live in my ed bubble and accept it simply because its a bigger bubble than it used to be. But honestly, like you said, I'd rather just have no bubble at all <3

  • friendoftherese1 May 1, 2018 at 5:19 pm

    Excellent! I've had a varying sized bubble for almost 40 years, and I'm darn tired of it. I can honestly say this is the first time I've taken a good hard look at my eating disorder, and am taking positive steps to be free of it. Your videos help so very much; thank you!
