Close well Gas Migration. How to control BHP during migration.

[@beverlybastian5741]

Good video & explanation keep up the good work. Hope to see some more videos & explanation in the future.

Good explanation.sir

[@s_tv2312]

Beautifully explained

[@JessieRutherford-y5i]

I am a new control instructor and your videos are awesome they help me so much do u have a video on the working window difference between formation psi and fracture psi

[@AjayVermaErigworld]

Thanks for appreciating my work but im sorry this time I don’t have such video but i will record this topic as its in my list.

[@andrixhernandez1323]

My dear sir, I wachted trainning vídeo with wait and weight method where the co- man told to driller keeping constant the casing pressure while I get ready the kill sheet! Regarding your explanation then that was a mistake? Because you are explaining we. Have to keep the sidpp!

[@ismailgarba1212]

Thank you so much sir and weldone. But what about when drilling is done...during production, and there is a bubble at the middle of a drilled hole and then its closed at the top. What happens to the bubble and pressure readings.

Sir please explane about BHP

[@AjayVermaErigworld]

Pls chk my videos i have BHP video both for static and circulation Bhp

why 2.15 ppg?

Its just an example. For explanation

hello sir, suppose we have taken a kick higher then the calculated kick tolerance value, then how we can kill the well? because if we use simple drillers method and wait and weight method then the formation below the casing shoe will get fracture before kick enters into the cased hole.

[@AjayVermaErigworld]

Baraiya Bhumin hi In that case we had to do bull heading method its also called non circulating method. In this method we bull head the formation fluid back to formation by pumping from surface.

[@baraiyabhumin130]

@@AjayVermaErigworld thanks for quick response sir, what if during bull heading we fracture the formation.... actually i read in a manual that they use low chock pressure method but i don't know about that so please if you can explain it briefly.

[@zeeshankhan-mb1jg]

When May You Consider Using the Bullheading Well Control Method? When the kick size is very big so you may not be able to control the excessive volume coming to the surface. When you need to reduce surface pressure in order to start further well control operations. When there is a possibility to exceed surface pressure and volume gas on the surface if the conventional methods (drillers’ method, wait and weight and volumetric) are performed. When there is no pipe in the hole while taking influx. The influx contains high level of H2S which can cause safety of personnel on the rig. When there is no feasible way to strip back to the bottom in order to kill in the flux below.

[@AjayVermaErigworld]

Then low choke pr killing method can be applied. Or bullheading can be done if conditions allowed

Dear sir please our do get influx wet thanks .. cyrille from Cameroon west Africa
