Obviously, to avoid allowing the pump pressure to increase, you must open the choke somewhat. For example, if you increase the pump rate and gain say an extra psi on your drillpipe gauge, we can assume the SCR at the new pump speed would have been psi greater than the original SCR.
To answer these type of questions, simply figure out what you would be doing with the choke: When we keep the observed casing pressure constant while changing the pumping rate, the bottom hole pressure remains the same.
The observed pressure in the drill pipe should be allowed to drop to the true value as the pumping rate is reduced and the other way round as the pumping rate is increased. Note that the pressure you read at the casing side of the U tube is the difference between the formation pressure and the BHP plus any additional pressure applied so, if this pressure remains constant, it means the bottom hole pressure is constant. Pls can you post more equipment questions just like you did for pnp.
Am preparing for my iwcf level 2 and i need some serious equipment question. Sir i am a roustabout position what are all the coureses in iwcf or iadc should i have to do for my carrer growth. This is a well control question……your drilling with a TDS 12, feet you have a washout in the drill string at 11, then you take a kick how do you control this matter?
Mail your queries at: ALso tell us more about your profile. The answer to this type of IWCF question will depend upon where the kick is in relation to the washout, mud type and influx type. Assuming you have gas kick in a WBM and the kick is below the washout, our first action should be to evacuate the kick out of the wellbore.
To do this, you need to use the Volumetric Method to allow the kick to migrate above the washout, while maintaining constant BHP. If you have no back-pressure valve above the washout, the process is easily accomplished by maintaining your DPP constant by bleeding off the extra DPP through the choke at intervals.
Also, visit and contribute to unsual questions section. Hello Sir I have a question. Hope to see a reply soon Ques 1 If during shut in the SIDPP is increasing and inspite of kill mud insertion it keeps on increasing what could be the possible reason?
If well is shut in and inspite of kill mud insertion as influx migrates upwards in annulus. SO increase in Hydrostatic head due to Closed well upward migration of influx is negated by increase in hydrostatic head of string due to kill mud insertion but negation is less in this case.
Like our website on facebook if you like answer. ALso if your query is not solved let us know we would try to make our answer more illustrative. Best regards Nawaf Senior drilling supervisor. My quest is — using volumetric method to kill a kick no DP in the hole after bleeding the gas keeping formation pressure close to BHP ,what will be the next steps to kill the well?
Dear rodger I was worked with you in Kuwait that time you r driller I am now working in n d c in abu dhabi. I have a question. Now lets say we drill 1 foot and get a kick. This is where I get confused. But how can this happen because the choke was WIDE OPEN when we took the CLF and we had psi on the pump and now we are circulating through the exact same flow path at the exact same rate 30 SPM with effectively no change in the well depth or geometry.
Your concern is totally logical. Very few people think this much in exploration industry. I am pleased to answer your query. What we follow in general practice is because of some assumptions and approximations. To clear the confusion first look at what we generally do without considering choke. Please read step by step even if it looks trivial.
One part of pressure loss is in drill string and another part is in annulus side. At shut in condition well is under control. Theoretically we should keep: Here we assume that maximum part of the pressure loss is in drill string and the extra annulus side pressure loss is kept over BHP.
Practically we maintain higher ICP than required: Theoretically, during circulation for well killing BHP should be same as at well shut in.
Recently I wanted to calculate the upforce from the well in accordance to the stringweight in relation to stripping. I came out with this formula: So, its area is same as that of a circle.

I also realized that what I thought was healthy had been impeding my life for decades. Paleo did away with my standard breakfast of old-fashioned oatmeal with raisins and creamer, plus a glass of orange juice. Grains turned out to be the culprit that kept me in the bathroom nearly every morning.
I learned that my orange juice, raisins, and creamer were loaded with sugar that was fueling, rather than burning, my fat cells. I knew that sugar fuels cancer cells too. I would rehydrate with coconut water and Gatorade, and limp through each afternoon on electrolytes and a long nap.
I felt so week, but no one knew. For lunch or dinner each day, I would eat a frozen meal. Though a dental hygienist trained in nutrition, I had no clue that I was eating totally wrong.
From my standpoint, I was doing a good job just by staying alive. I felt like doing some chores around the house and enjoyed the most mundane tasks. The simple pleasures of cooking and eating healthy food quickly made radical, positive changes in my life. I even enjoy doing dishes. I take pictures of my beautiful plates full of food half vegetables and share them online with my new paleo support team.
I find joy in encouraging others on their journey, and love this resource. During the first 30 days, I followed the plan as best I could, not counting the cookie or two that I found in the freezer and one piece of pumpkin pie for Thanksgiving. Not everything was organic or grass-fed or free-range.
The learning curve seemed steep. But I must have been doing some things right, for the legs and sleeves on my clothing kept getting longer. I hoped for five or ten pounds. Happiness returned in my life, along with a sense of purpose and determination to stay on-course. But I still had to face that scale on Day That milestone came quickly, and I was shocked to learn that 18 pounds were gone!
Maybe even 20 pounds, counting those first three days before I could weigh myself on Day 4. I celebrated by sharing the news with new friends online and decorating for Christmas. I prepped and grilled some vegetables, shaking them in a Ziploc bag with olive oil.
Wild-caught salmon accompanied half a plateful of yummy grilled vegetables for dinner, replacing frozen meals that I no longer buy. Again, I took a picture of my plate. Paleo is a joy, a life-changing adventure. As the first twenty pounds melted away, my blood glucose dropped eight points, to I sleep through the night, rather than wake up every two hours. My clothes fit better. I feel satisfied with my nutrient-dense food, and seldom need a snack.
Earlier I mentioned my team. So are my nutrition-conscious PCP and hematologist. My diagnosis is SMM, or smoldering multiple myeloma, and is not considered cancer. All of my doctors are percent in favor of paleo as part of my program. With a progression rate of only one percent per year not incremental , my chances of outliving it look good. But I want to have every possible chance of being fully here for my kids, my grandkids, and myself, enjoying each day to the max.
Paleo has given that to me, serving as the cornerstone of my healthy new life. I love it — not only for the weight loss but for how good it makes me feel. My name is Deborah Tubbs and when I decided to embark on this journey, my husband Marvin said he wanted to do the Day Challenge with me. We are both 65 years old. I wanted to drop some pounds but, most importantly, I wanted to feel better. At the time, I had major digestive issues. I woke up every day not feeling well, always bloated and never knew what food was causing it.
Sometimes I could eat something with no ill effects and the next time that same food would cause me major issues.
We emptied our pantry and refrigerator of all the temptations and began the Challenge. We ate lean meats, fresh veggies and have eliminated sugar.
We never went hungry. My husband used to be on Metformin for Type 2 diabetes. What an interesting and informative 30 days that was! I feel like the Paleo Secret Day Challenge was a success for me. Before the challenge I would wake up every morning feeling pain inside my body. Usually it manifested itself around my mid-section. I also had this sciatica condition where pain would shoot down the back of my right leg. It was really uncomfortable. I would start my day vaping cannabis just to ease the pain during the day Cannabis is legal in Seattle.
On day 6, I woke up and the pain was gone. The sciatica pain was subsiding. Later in the challenge, the sciatica pain disappeared altogether. Plus I stopped using Cannabis to treat the pain.
For fitness I started walking again. My pet Chihuahua and I would walk the neighborhood about four times a week. Usually we traveled 2 to 2.
There is a nice hill to climb during the walk, which got less challenging every day. One time Zarya my chihuahua and I walked 3 miles! My before and after pictures did not show much change. However, I started the challenge at pounds and I ended the challenge at pounds.
I feel really great about losing that weight. For October, I am doing the challenge again. For the fitness part, I am changing to 1 to 2 mile walks five times a week.
My goal is to lose another ten pounds in October. My overall goal is to get my weight down to pounds. Maybe I can reach I feel that will take a year to do but now I have all this newfound knowledge. I am getting to know how my body reacts to food and exercise. I think I finally found a method to achieve this. Plus I am learning how to cook healthy meals which is a lot of fun too. Plus I am saving money in that we are not going out to eat as often during the month. I want to thank Chad and Brenda for their website and their helpful advice over the past 30 days.
Everything was so helpful to me and I am thankful for how you both approach this. Thank you, thank you, thank you. Before the Day Challenge, I had hip surgery on my left hip and pain in my right hip.
I anticipated having to have surgery on that hip as well. The pain I felt in both hips, even after surgery was so bad that I was having a hard time sleeping and working.
The pain was worse at night, but never went away. I have had this pain for years. I had done physical therapy, steroid shots, pain management, and surgery. I did not look forward to more surgery as it did not relieve the pain.
Because of the pain, exercising had been nil — even swimming hurt. I decided that I was all in. I had one day that I would say that I cheated. My daughter is moving to Minneapolis, and we had a special dinner. I had a small piece of cake, but everything else was strictly Paleo. Other than that day, I did not cheat at all. I also did the 3-Minute flow program.
I was actually afraid to start. After two-weeks I noticed that the pain in my hips was almost gone. I have had no pain at all in my hips since Day I realized that I felt rested for the first time in years. I only lost 5 lbs. Today I have started a new exercise regimen. I expect over the next few weeks that I will begin to see greater weight loss.
