Good job. But let me correct you one thing is that Alizarin Red is used for Dolomite not Limestone. Also in sample description we will write visual porosity before hydrocarbon shows.
1- Thanks for your reply and i need to clarify that Alizarin Red S is used to identify Limestone as i explained not Dolomite as your correction. - Alizarin Red S : Alizarin Red is a staining solution used to identify Limestone. When placed in contact with Calcium Carbonate, Alizarin will produce a deep red colored reaction. The reaction will be rapid when the carbonate content is in the cementation of the rock. Determination of Limestone vs Dolomite using 10% HCL can be subjective. Use Alizarin Red as a differentiator when combined with HCL test information. (Halliburton manual) - Staining carbonate minerals The staining of carbonate minerals has a long history (Lemberg, 1887) and involves a plethora of different methods (Freidman, 1959, 1971; Reid, 1969). General carbonate stain The most widely used stain for carbonates employs a mixture of Alizarin red S and potassium ferricyanide dissolved in a dilute hydrochloric acid solution. Set procedures are published for this dual stain (Dickson, 1965, 1966; Evamy, 1963, 1969) but the stain can, within certain limits, be modified to suit the needs of the observer and the type of material being stained. The organic dye Alizarin red S (ARS) will produce a pink to red stain on any carbonate that will react with dilute acid. The reaction between carbonates and acid is usually controlled (1-2 minutes at 25°C for thin sections) so that the more reactive minerals, such as calcite and aragonite, stain red but the less reactive ones, such as dolomite and siderite, remain unstained ( link.springer.com/referenceworkentry/10.1007/978-1-4020-3609-5_220 ) 2- I agree that we have to write Visual porosity before hydrocarbon shows in the sample description and this exactly what i explained and also i gave example for the sample description in the power point slide which show that the Visible porosity was written before Oil Shows. Thanks very much for your cooperation
thanks for the lecture so much. And can you explain more about the tracer (calcium carbide, rice, corn...), downtime and how to run carbide bomb , please?
Thank you sir 😊 lots of prayers from Pakistan ❤
It's interesting lectures especially to the Mudlogging Engineer
very much informative , and the way of explaining things is excellent .
Good work i really appreciated
Thank you ...بارك الله فيكم
Thank you very much, sir. Appriciate it!
Thanks,, very informative webinar
Thank you sir..👍🏻

Hello 👋 Sir , I have a question How can I contact with you
Informative Session
