Abstract: A load handling device for automatically storing a load in an automated warehouse has a base frame onto which wheels are rotatably connected to allow translation of the load handling device along a storage aisle. First handling members are operatively connected to one or more of the wheels. Operational portions define a temporary support plane for the load, and second handling members are operatively connected to the operational portions for moving the operational portions between a base position and a lifting position. A measuring wheel rotatable about a wheel rotation axis is connected to the base frame along a wheel translation direction. A connecting coupling transfers rotational motion of the measuring wheel to an angular position detection device having a device rotation axis parallel to the wheel rotation axis even during an offset variable in time along the wheel translation direction between the device rotation axis and the wheel rotation axis.

Abstract: Composition of water-based drilling fluids characterized in that they comprise anions with a high hydrodynamic radius.

Abstract: A core sampling method, particularly for the oil industry, wherein actual core sampling is performed by means of a core sampler (1) comprising at least one Inner barrel (5), an outer barrel (2) and a bit (3), and a substantially axial compressive force (F) is exerted on the top (7A) of a core sample (7) being formed, at least during a major part of the core sampling process, said force being within a range determined particularly on the basis of the material of the core sample (7), whereafter the force (F) is removed at the latest before the core sample (7) is withdrawn from the inner barrel (5). A core sampler for carrying out the method is also provided.

Abstract: The present invention relates to a device used for the direct measurement of the permeability of rock fragments coming directly from the drilling of an oil well and commonly called cuttings, consisting of a hollow cylindrical body (c) that presents an inlet hole for the fluid (i), a thread for closing it (h) and a hydraulic seal (g) in which is placed the sample holder disk (d) which rests on the seal (g) and is overlapped by a porous sintered steel septum (e) on which a closing plug (f) is situated with an outlet hole for the fluid (i') and the same is also provided with a thread (h') to enable it to close on the body (c).The device can be used to obtain, directly on site, the measurement of permeability along the whole length of an oil well.
