摘要： This disclosure relates to a system and method for generating a change in pressure proportional to fluid viscosity. In particular, the disclosure discusses a viscosity dependent pressure differential system. The system can comprise a first pilot stream, a second pilot stream, and a pressure sensing device that reads a differential pressure across a first junction on the first pilot stream and a second junction on the second pilot stream. The first junction is between a first section having a first predominant pressure loss characteristic, and a second section having a second predominant pressure loss characteristic. Similarly, the second junction can be between a third section having a third predominant pressure loss characteristic and a fourth section having a fourth pressure loss characteristic.

摘要： A production pipe for production of oil or gas from a well in an oil and/or gas reservoir, or for injection of fluids into a well in an oil and/or gas reservoir, includes a production pipe with a lower drainage pipe. The drainage pipe is divided into sections with one or more inflow restriction devices which control the flow of oil or gas from the reservoir into the drainage pipe on the basis of calculated loss of friction pressure along the drainage pipe, the calculated productivity profile of the reservoir, and the calculated inflow of gas or water.

摘要： A system and method for fracturing a well, wherein the system can comprise a base pipe comprising an insert port capable of housing a stop ball partially within the chamber of it, and a sliding sleeve. The sliding sleeve can comprise a first sleeve with an in inner surface. That inner surface can comprise a void. The first sleeve can be maneuverable into two positions. In the first position, the void can rest on a surface of the base pipe not comprising an insert port. Such positioning can prevent a stop ball from exiting the chamber of the base pipe. In the second position, the void can rest over an insert port. Such positioning can allow the stop ball to the chamber of said the base pipe and to enter the void.

摘要： A method and a system are disclosed for the transportation and separation of gas from liquid and solid media in one or several stages in a manner so that the pressure in the gaseous phase from an early separator stage (1) or from another gas deposit is utilized for the transportation of the fluids produced in subsequent separator stages (2, 3, 4). Gas which is separated at high pressure in an early separator stage (1) or gas from another gas deposit is fed into a separator (3) which has effected separation at a lower pressure and the high pressure gas forces out the separated fluid which is present in the separator receiving the high pressure gas. The separator stage at which high pressure gas is received from a preceding stage or another gas source, is made up of several identical separators (2, 3, 4) which alternate in carrying out the separation phase (2), output (3) and decompression (4) so that there is at all times one separator carrying out functions within one phase.

摘要： According to a preferred aspect of the instant invention, there is provided a boat hull that is an improvement over the state-of-the-art stepped hull. More particularly, in contrast to prior art designs, the instant steps are specifically constructed to have an opening/air passage situated on the side of each step. The air passage will be preferably placed on the side of the step closest to the surface of the water or farthest away from the keel of the boar. This feature tends to introduce more air under the boat, thereby reducing water drag on the hull and improving its overall performance.

摘要： According to a first preferred aspect of the invention, there is provided a downhole sand screen device for use in well completions that comprises a plurality of isolated individual sand screens. Further, in the preferred arrangement the instant invention consists of two screens, one concentrically nested inside of the other, and further wherein the screen sections are not continuous but rather are periodically interrupted by sections of blank pipe. Further, the screen sections are arranged so that a screen section on the outer pipe will be matched by a corresponding, but staggered, blank pipe section on the inner pipe. As a consequence, if a hole develops in one of the outer screen sections the movement of sand will be blocked from entering the wellbore by a second/inner screen.
