Patent CA-2212696-A1 (CA)
Inventor: HENKE JOSEPH A
IPC: E21B43/116
Filed: 1997-08-08
Abstract: A tool connector is provided for downhole use in oil and gas fields. The tool connector includes a stinger and a stinger receptacle.  The stinger is adapted to be stabbed into the stinger receptacle.  A loaded engaging member movable between arunning position before the stinger is stabbed into the stinger receptacle and a latched position when the stinger is stabbed into the stinger receptacle to latch the stinger and the stinger receptacle together.  A release member retains the loaded engaging member in the running position.  When the stinger is stabbed into the stinger receptacle and a set force is applied to the stinger and stinger receptacle, the release member releases the loaded engaging member to move to the latched position and latch the stinger and the stinger receptacle together.  According to a second aspect of the invention, the tool connector is releasable, further including a releasable stop member to stop the engaging member in the latched position.  When the stop member is released, the engaging member moves to a released position such that the stinger and stinger receptacle are separable.  According to a third aspect of the invention having particular application to perforating gun sections, a tool connector is provided with an internal explosive transfer system for transferring the detonation signal from one perforating gun, through the perforating gun connector, and to the next perforating gun.  In addition, a method of connection a first tool section to a second tool section is provided.

Abstract: With regard to a significant reduction in the tolerance range or margin to be taken into account in the design of a switched-capacitor circuit which is monolithically integrated by means of enhancement-mode insulated-gate field-effect transistors there is provided at least one opamp. This opamp contains a resistor which determines its quiescent current and is realized as a transistor operated in the permanently current-conducting state. An on-chip clock oscillator generates a clock signal. This oscillator is either an RC clock oscillator, whose frequency is determined by an oscillator resistor, which is realized as a transistor operated in the permanently current-conducting state, and an oscillator capacitor, or a current-controlled clock oscillator, whose frequency is determined by the quiescent current of the opamp. At least one capacitor is charged or discharged during operation by the opam via at least one switch in the form of a transistor clocked by the clock signal.

Patent CA-2231947-A1 (CA)
Title: Method of determining fluid inflow rates
Inventor: ALEXANDER LLOYD G
IPC: E21B47/00
Filed: 1998-03-12
Abstract: A method is provided for determining the actual inflow rates of gas and liquid into a wellbore from a reservoir. The wellhead is first closed and the wellhead pressure is measured over time. For a briefly period, gas is flowed from the wellhead and the wellhead pressure is measured again. Using the two conditions, the original wellbore gas volume and an original fluid inflow rate is determined. Gas is again flowed from the wellhead, both the flow and the pressure being measured, but this time for a prolonged duration, sufficient to affect the reservoir. Assuming the original gas inflow rate and original gas volume remain unchanged during the prolonged flow, a total rate of fluid inflow from the reservoir is determined, and finally an incremental inflow rate of fluid from the reservoir is calculated as being the difference between the total rate of fluid inflow less the original rate of gas flow. If the well is a gas well, the incremental fluid inflow is the actual gas inflow rate. If the fluid inflow is known to be liquid, then an incremental change in volume is equivalent to the liquid inflow rate. Using an exponential relationship for the pressure change during wellhead flow, a theoretical curve pressure response curve can be created, displayed and compared against the actual pressure response, any deviation therebetween being indicative of fluid inflow from the reservoir.
