Because of the constant application of surface backpressure, the dttl method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean.

Repeatable and comparable inspeciton of concrete joints


A joint inspection system is described herein that develops and implements a practical, rapid imaging system to detect the presence of contaminants or moisture on the adhesion surfaces of a joint and to identify the presence of micro-fractures, fractures, or anomalies that will affect the integrity of the concrete adjacent to the joint faces (elements that could develop into post-construction spalling). The system utilizes existing technologies to provide an accurate, comprehensive, permanent, reviewable, comparable, location-identifiable imagery of the joint channel and the pavement surfaces immediately adjacent to the channel.

Stator component of vacuum pump


The present invention provides a stator component of a vacuum pump, which is suitable for reducing the fracture energy (energy of fracture that occurs when a rotor of the pump is damaged during its rotation) and the size of the pump, and also provides a vacuum pump having this stator component. In the vacuum pump, a spacer or of a thread groove pump stator, which is a stator component forms a gap satisfying the following <<condition>> between an outer circumferential surface of each of housed in a pump case of the vacuum pump, and an inner circumferential surface of the pump case, with the stator component being housed in the pump case.

Pseudoelastic materials as additives to enhance hydraulic fracturing


Systems and methods for enhancing hydraulic fracturing productivity for recovery of a reservoir fluid from a reservoir formation having an open fracture includes providing a shape memory filter that is pseudoelastically deformed and contained within a soluble container. The shape memory filter and soluble container are pumped into the open fracture so that the soluble container dissolves and the shape memory filter returns to an expanded filter shape.
