Horizontal Drilling & Directional Drilling: Natural Gas Wells
Horizontal Drilling & Directional Drilling: Natural Gas Wells

Most horizontal wells begin at the surface as a vertical well. ,Drilling, progresses until the drill bit is a few hundred feet above the target rock unit. At that ,point, the pipe is pulled from the well and a hydraulic motor is attached between the drill bit and the drill pipe. The hydraulic motor is powered by a flow of ,drilling mud, down the ...

Yield point is a measurement of the drilling fluids carrying capacity in a dynamic state, or when the fluid is moving along the borehole. Gel strength is a measurement of the carrying capacity of the drilling fluid when the fluid is static or when the fluid is not moving in the borehole.

Funnel Viscosity and Rheology of Drilling Mud
Funnel Viscosity and Rheology of Drilling Mud

The funnel viscosity is time in second of drilling mud flowing through the Marsh Funnel Viscosity. Rheology is the study of flow and deformation of fluid. There are several rheology values such as gel strength, plastic viscosity (PV), and yield point (YP). These two concepts are very important to …

1. n. [Drilling Fluids] A two-parameter rheological model widely used in the drilling fluids industry to describe flow characteristics of many types of muds. It can be described mathematically as follows: τ = YP + PV(γ), where τ = shear stress γ = shear rate YP = yield point PV = plastic viscosity.

12/9/2019, · The yield point for varying IMME concentration in the proposed O/W emulsion mud falls in an acceptable range as per API standard (Sulaimon et al. 2017). During circulation, if an operation stops for some operational reason, the gel strength and the yield point are key variables to suspending the cuttings from accumulating behind the drill bit.

TAS (ASX) Ann: Lake Torrens IOCG Project - Drilling Update

I have spent this weekend going over TAS's "Lake Torrens IOCG Project - ,Drilling, Update" which of course was all about the results of FMG's ,drilling, at Vulcan North i.e. VUD018 and VUD019. It is pretty obvious from this announcement, that a geologist has had a very close and very long look at the drlll cores of both VUD018 and VUD019.
