Mechanism research on technical policy of liquid extraction depressurization development for buried hill reservoirs [PDF]

E3S Web of Conferences, 2021
Most of buried hill reservoirs are in the late stage of water flooding development, especially for this kind of reservoir with large water-oil volume ratio, it is more difficult to develop the residual oil in matrix system.

Numerical and experimental investigation on the depressurization capacity of a new type of depressure-dominated jet mill bit [PDF]

Petroleum Science, 2020
AbstractEfficient cuttings transport and improving rate of penetration (ROP) are two major challenges in horizontal drilling and extended reach drilling. A type of jet mill bit (JMB) may provide an opportunity to catch the two birds with one stone: not only enhancing cuttings transport efficiency but also improving ROP by depressuring at the bottom ...
