Tracking Drilling Efficiency Using Hydro-Mechanical Specific Energy
SPE/IADC Drilling Conference and Exhibition, 2009Abstract Over the last few years, different types of bits have been introduced to meet the challenges of steerable as well as rotary steerable systems; and it is imperative that bits be utilized optimally in these systems. As challenges increase with increasing depths, it becomes even more important for one to efficiently utilize the ...

Agitation Tools Enables Significant Reduction in Mechanical Specific Energy
SPE Asia Pacific Oil and Gas Conference and Exhibition, 2012Abstract Mechanical Specific Energy (MSE) is a term used by the oilfield drilling industry to describe several formulae quantifying the energy input within a drilling system. MSE mainly describes the Mechanical (WOB and Torque), for a given unit (Length, area or mass), and the energy required to do the work (i.e. force, time, distance).

Maximizing Drill Rates with Real-Time Surveillance of Mechanical Specific Energy
Proceedings of SPE/IADC Drilling Conference, 2005Abstract The concept of Mechanical Specific Energy (MSE) has been used effectively in lab environments to evaluate the drilling efficiency of bits. MSE analysis has also been used in a limited manner to investigate specific inefficiencies in field operations.3,4 In early 2004, the operator initiated a pilot to determine whether the ...

Geomechanical parameter estimation from mechanical specific energy using artificial intelligence
Journal of Petroleum Science and Engineering, 2019Abstract A comprehensive knowledge of geomechanical characteristics of the formations above a reservoir (cap rock, in particular) can prevent a large spectrum of problems during drilling operation. Furthermore, access to such information during drilling operation greatly contributes to proper adjustment of controllable parameters and enhanced rate of

Specific mechanical energy – An essential parameter in the processing of amorphous solid dispersions
Advanced Drug Delivery Reviews, 2021Specific mechanical energy (SME) is a frequently overlooked but essential parameter of hot-melt extrusion (HME). It can determine whether an amorphous solid dispersion (ASD) can be successfully processed. A minimum combination of thermal input and SME is required to convert a crystalline active pharmaceutical product (API) into its amorphous form.

SPE Annual Technical Conference and Exhibition, 1992
ABSTRACTThe conventional way to assess drilling performance in the oil field is to compare actual performance to statistical standards derived from offset records. By their nature, these standards are subjective and variable. While they are ideal to monitor short-range performance and trends in well- known, older fields, they lack the power of physical

Theories and Applications of Pulsed-Jet Drilling With Mechanical Specific Energy
SPE Journal, 2016Summary Mechanical specific energy (MSE) is the amount of energy required to destroy a unit volume of rock. The main work of this study is to bring the hydraulic energy of a pulsed jet into an MSE model and further analyze the mechanism of improving the rate of penetration (ROP) for pulsed-jet drilling on the basis of the model ...

Determination of Specific Mechanical Energy Distribution on a Twin-Screw Extruder
Journal of Agricultural Engineering Research, 1997The distribution of specific mechanical energy (SME) dissipated inside a co-rotating, self-wiping, twin-screw extruder was estimated by conducting energy balances on each zone of the extruder. SME dissipation was studied under three different steady state conditions in which the zone before the die was kept adiabatic or under constant cooling or under ...

Facts, Fallacies and Pitfalls of Using Mechanical Specific Energy (MSE) – Part 1
SPE/IADC International Drilling Conference and Exhibition, 2023Abstract Over the years, some researchers have used Mechanical Specific Energy (MSE), which is said to represent the amount of energy needed to drill a unit volume of rock, to quantify drilling efficiency. MSE was originally introduced by Teal for the mining industry in 1964.
