Integrated well logging systems and methods
An integrated well logging system includes an elongated stem portion configured to lower the well logging system into a hydrocarbon well, a multi-finger calipers for measuring the internal diameter of the annulus of the hydrocarbon well, the multi-finger calipers comprising a plurality of measuring arms, a first crossover configured to connect the stem portion to the multi-finger calipers, a static bottom hole pressure survey configured to measure the pressure at a location within the hydrocarbon well, the static bottom hole pressure survey comprising a plurality of memory gauges, and a second crossover configured to connect the multi-finger calipers to the static bottom hole pressure survey.
1. A method for performing a static bottom hole pressure survey and caliper log in a single run, the method comprising:
providing an elongated stem portion to lower an integrated well logging system into a hydrocarbon well;
providing a multi-finger calipers portion for measuring the internal diameter of an internal wall of the hydrocarbon well, the multi-finger calipers portion comprising a plurality of measuring arms;
providing a first crossover to connect the stem portion to the multi-finger calipers portion;
providing a static bottom hole pressure (SBHP) survey portion to measure a pressure at a location within the hydrocarbon well, the SBHP survey portion comprising a plurality of memory gauges, the plurality of memory gauges directly connected to each other in series at a terminal end of the logging system;
providing a second crossover to connect the multi-finger calipers portion to the SBHP survey portion,
conducting a SBHP survey while running the integrated well logging system in hole; and
activating measuring arms of the multi-finger calipers upon reaching a target depth in the hydrocarbon well, and then pulling the integrated well logging system up the hydrocarbon well while continuously measuring, with the multi-finger calipers, a surface condition of the internal wall of the hydrocarbon well from the depth to surface.
2. The method according to claim 1 , wherein the elongated stem portion further comprises a rope socket, a third crossover, a swivel joint, an elongated stem, and a knuckle jar.
3. The method according to claim 1 , wherein the multi-finger calipers portion comprises a battery housing, and a caliper portion memory gauge, and where the plurality of measuring arms includes a first plurality of bendable caliper arms.
4. The method according to claim 3 , further including electronics, power supplies, and sensors, and wherein the battery housing comprises a steel case configured to isolate the electronics, the power supplies, and the sensors from the hydrocarbon well.
5. The method according to claim 3 , wherein the plurality of memory gauges comprise an electronic pressure gauge that samples and records downhole pressures, with data representing the downhole pressures being stored in a non-volatile memory, ready for downloading to an acquisition equipment when the integrated well logging system has been retrieved to surface.
6. The method according to claim 3 , wherein the multi-finger calipers portion further comprises a multi-finger caliper tool, and a fourth crossover, and where the plurality of measuring arms includes a second plurality of bendable caliper arms.
7. The method according to claim 6 , wherein the plurality of measuring arms comprises 20 to 120 fingers or measuring arms.
