Granted: 2004-02-17
Abstract: A progressing cavity pump (10) is provided in which the compressive fit between the rotor (18) and stator (20) is gradually reduced with the distance from the suction end (32) of the pump. This gradual decrease in compressive fit allows for increased slippage near the discharge end of the pump, resulting in better distribution of the internal differential pressure along the length of the pump. The differential pressure distribution in turn reduces heat buildup near the discharge end (34), increasing the life of the elastomeric stator or rotor.

Abstract: A computer method (500-570) draws overlapped two-dimensional shapes (A, B) and two-dimensional projections of three-dimensional shapes (C') onto a projection plane (102) in a system of world coordinates (X, Y, Z). The method instantiates a plurality of two-dimensional geometry class objects (320', 320"), each of which includes an order attribute (ORDER) specifying an overlapped position for depicting a corresponding two-dimensional shape (A, B) on the projection plane (102) positioned orthogonally to the Z coordinate of the world coordinate system. The method (500-570) instantiates a three-dimensional geometry class object (330', 330") including a Z-value (Z-value) for a position along the Z world coordinate of the three-dimensional shape (C'). The method sons the plurality of two-dimensional geometry class objects by their respective order attributes in a sorting table in the memory (510). The method sorts the three-dimensional geometry class object by its Z-value in the sorting table and orders it in a composite order with the two-dimensional class objects in the sorting table (520). The method then draws the two-dimensional shapes (A, B) and two-dimensional projections of the three-dimensional shapes (C') onto the projection plane (102) in the composite table (400) order, to depict an overlapped appearance of the shapes.

Abstract: A blowout preventer (BOP? protector is adapted to support a tubing string in a wellbore so that the tubing string is directly accessible during a well treatment to stimulate production. The BOP protector includes a mandrel having a sealing assembly mounted to its bottom end for pack-off in a casing of a well to be stimulated. The mandrel is connected at its top end to a fracturing head, including a central passage and radial passages in fluid communication with the central passage.      The mandrel is locked in a fixed position by a lockdown nut that prevents upward movement induced by fluid pressures in the wellbore. The advantages are that the BOP protector permits access to the tubing string during well treatment and enables an operator to move the tubing string up and down or run coil tubing into or out of the wellbore without removing the tool. This reduces operation costs, saves time and enables many new procedures that were previously impossible or impractical.
