Khalil Ferris commented on Rachain Jetjongjit's blog post pH in drilling mud
"Calcium Hydroxide (used in Cement jobs) Can have a pH source since Hydrogen is present ( As mentioned above). Calcium Nitrate does and should be Alkaline. Usually this is an issue when drilling out cement.  Just food for thought  "

How to Determine Mud Motor Failure

Mud motor failure downhole may be happened from time to time. The questions that are usually raised are things like “How do I know if the mud motor fails down hole?” and “What indications will I see that this has happened?” etc. Due to this, I would like to share my personal experience regarding mud motor failure and its symptoms.The following signs indicate that you may be faced with downhole mud motor breakdown.Frequent Mud Motor Stall– Motor stall happens when the rotor of the mud motor has…See More

Drilling Waste Minimization Strategies

Drilling waste minimization is a method to reduce any waste generated from drilling operation. The ideal goal of it is to generate zero residue requiring final disposals. People have developed technologies for two main reasons which are project cost reduction and environmental protection.

Typically, the drilling waste minimization starts with reducing amount of drilling waste, recycling and recovering waste…

How To Determine Hole Size By Fluid Caliper

This article will demonstrate you how to determine hole size by fluid caliper. First of all, you need to know what is the fluid caliper is. The fluid caliper is one simple way to calculate hole diameter. The concept is based on hole volume, annular capacity, and inner capacity. You pump any substance and when you seen it on surface, you back calculate the hole size based on strokes pumped. It is quite tricky to explain so I would like you to see the example below which it will make you clear…
