The drilling mud circulating system components comprises the following equipment: Active Tank This is the tank from which drilling fluid is pumped downhole and to which drilling fluid returns from the hole is received. The route taken by the drilling fluid when circulating is called the active (circulating) system. At the start of …
Retort analysis for drilling fluid is used for determining oil, water and solids content in the mud, comprising a sample chamber assembly of known volume filled with mud. The sample chamber is put in a heating chamber to boil off the water (and oil), which passes via a condenser tube into a graduated glass measuring …
Samples are examined under a microscope for: The objective is to depict changes in lithology and the appearance of new formations. The microscope and ultraviolet light are complementary tools in reconstructing the characteristics of the originating strata. An estimate of the lithology, staining, and porosity percentages is made carefully since factors such as grain shape …
A definite time interval is always required for pumping the samples from a particular depth to the surface where they can be collected. When determined, This critical time interval is called “Drilling lag time” and can be measured in terms of pump strokes and time. This lag applies to all downhole information, including formation cuttings …
What Is The Definition Of Drilling Mud Pump Output? The rig pump output is the output of the drilling mud pumps, which can be expressed normally in gallons per stroke, bbls per stroke, or m3 per stroke. This term is a very important figure which is necessary to be known as it is important for …

SHALE INHIBITION CHEMICALS | INTRODUCTION There are three approaches to stopping the clay formations /shale deteriorating upon contact with the drilling fluid /mud: In the younger shales the main destabilizing mechanism is dispersion of the clay lattices by penetration of water into the interlattice zone. Limiting water penetration in these formations is difficult due to …
The purpose of these BOP & Well Control drills procedures or exercises is to familiarize rig personnel with the various equipment and with the techniques that will be employed in the event of a Well Kick. Here, we explain all well control drills including trip drill procedure, pit drill in drilling, H2S drill, Emergency drills, …
