Paper Number: ARMA-2023-0195
... are available for assessing the degree of wear. Thus, quantitatively evaluating the wear of PDC drill bits has been a persistent research challenge. Evaluating drill bit wear status mainly relies on rock breaking efficiency and mechanical specific energy. In this study, a physical model was used to calculate...

... duration of 0.005 s to ensure a fast and steady average force required to linearly cut the rock. The contact between the PDC cutter and the rock. (2) Phase II mechanical specific energy is the energy consumed to contains a cutting process with a cutting speed of 1 m/s break per unit volume of rock...

... on mechanical specific energy (MSE), and compares the effects seen in the lab to those seen during the field trails. It was found that in specific instances the pVARD tool causes a reduction in MSE. The laboratory scale tool saw the best result as more varied operational ranges could be experimented with than...

Paper Number: ARMA-2018-1098
... ABSTRACT: In this study, an artificial neural networks (ANN) model as an artificial intelligence (AI) technique is proposed to determine the formation pore pressure from data of two critical drilling parameters named mechanical specific energy and drilling efficiency. These parameters (MSE...

... and finite element methods. The numerical models were carried out under different geometrical configurations, varying the cutter chamfer size and back-rake angles. The forces generated on the cutter are translated into mechanical specific energy, MSE as this parameter is often used to measure drilling...

... equal; i.e. the balanced pressure conditions with the pressures ranging from atmospheric pressure to 450 psi. The results of the first set of tests show that at 210 psi underbalance, the Mechanical Specific Energy (MSE) is 58% of the MSE at the balanced conditions; while, extrapolating the trend the MSE...

Paper Number: ARMA-2012-622
... ABSTRACT: The relationship between Mechanical Specific Energy (MSE) and the rate of penetration (ROP), or the depth of cut per revolution, provides an important measure for strategizing a desirable drilling operation. The ROP of drilling can be related to the depth of cut for a single cutter...
