The Obama administration has in fact halted drilling permits on federal lands.



Unbeknownst to most folks outside the industry, President Obama's response had entirely NOTHING to to do with Gov. Romney's line of questioning about the Obama administration's intentional log-jamming of drilling PERMITS on federal lands.…

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.…

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…

Cutting slip velocity is velocity of cutting that naturally falls down due to its density. In order to effectively clean the hole, effect of mud flow upward direction and mud properties must be greater than cutting slip velocity (settling tendency of cuttings). Otherwise, cutting will fall down and create cutting… Continue

pH is a value representing the hydrogen ion concentration in liquid. We use it to indicate acidity or alkalinity of drilling mud especially water base mud. Let’s talk about general of the pH. The pH is presented in a numerical value (0-14) which means an inverse measurement of hydrogen concentration in the fluid.

The pH formula is listed below;…

Newtonian fluid model is the simplest rheological model. Let’s describe in the mathematical way, a relationship between shear stress (lb/100 ft2) and shear rate (1/sec), named a consistency curve, is a straight line which passes through the original (see the figure below).…

The gel strength is the shear stress of drilling mud that is measured at low shear rate after the drilling mud is static for a certain period of time. The gel strength is one of the important drilling fluid properties because it demonstrates the ability of the drilling mud to suspend drill solids and weighting material when circulation is ceased.

How can we get…

Plastic Viscosity (PV) is the resistance of fluid to flow. In the field, we can get the PV from a viscometer. Typically, the viscometer is utilized to measure shear rates at 600, 300, 200, 100, 6, and 3 revolutions per minute…

For want of a nail the shoe was lost.

For want of a shoe the horse was lost.

For want of a horse the rider was lost.

For want of a rider the battle was lost.

For want of a battle the kingdom was lost.

And all for the want of a horseshoe nail.



Ancient Proverb



There is practically no field of endeavor that illustrates the truth of this proverb than the drilling industry. From the smallest house well jobs, to the most technically challenging… Continue

Lag time is traveling time interval required for pumping cuttings from each particular depth to surface. It can be expressed in terms of time (minutes) and pump strokes.





The lag time always changes when a well becomes deeper and/or pumping speed change. Two factors, affecting lag time… Continue

Steering (orienting or sliding) is drilling with mud downhole steerable mud motor. Drilling with the steerable motor does not rotate drill pipe because it uses hydraulic power to drive down hole motor and bit. Steering is used in order to control well direction.



Rotating is drilling with Topdrive or rotary table and… Continue

The Coming Oil and Gas Boom – Are You Ready?



Every new beginning is some other beginning’s end... Great lyrics from a pretty decent Matchbox Twenty song, and a great lead-in to what will soon be the next great Oil and Gas Boom!



Get ready, because it’s coming.



OK, so maybe this “boom” isn't starting off with a bang, more like a whimper...But I believe it has begun. The worst seems to be behind us as the recent stock market rally and rising energy prices may be… Continue

The "New" National Energy Policy



The recent election of our new President brought with it renewed hope of a national energy policy that would be a step in stabilizing the volatile energy markets here at home and thus ensuring work for those of us employed the in Oil and Gas sector. T. Boone Pickens and his army of followers seemed to have forced energy into the limelight, leaving aspiring politicians no choice but to respond. The message to all of us, in one form or another was… Continue
