1 Petroleum technology Pressure Sensor © 2012, all rights reserved Gauges Deployment

2 Petroleum technology Pressure Sensor © 2012, all rights reserved Example: reservoir monitoring and control Surface sensors and controls Multi-phase flow rate Valve and choke control Pressure measurements Sand detection Permanent downhole sensors flow rate and density monitors Submersible pumps control pressure and temperature gauges Client office multi-channel web access SAFE ZONE EXPLOSIVE ZONE Wireless communication

3 Petroleum technology Pressure Sensor © 2012, all rights reserved HPHT Recording Sensor OT /OT /OT Deployment options Operation (gauges Installation): Where ever you wish to use the Gauges their installation may be assured by your operator (contractor).

4 Petroleum technology Pressure Sensor © 2012, all rights reserved 1 - Surface - Using adapter OT – As a recorder – As a live measurement 2- Downhole - As a recorder – In a side-pocket mandrel – In a user defined carrier 3- As a live measurement – On a user-defined wireline cable or insulated slickline cable using communication module 0T Deployment options - Summary SlicklineSlickline, a cabling technology used for oil well completions and maintenance Wireline (cabling)Wireline (cabling), a cabling technology where a current is sent to downhole logging tools in oil well exploration and completions

5 Petroleum technology Pressure Sensor © 2012, all rights reserved Surface Deployment Sensor is connected to pressure line using adapter OT (ring) Ring held in place by Autoclave 1/4 OD tubing Can then be connected to other pressure connection types : Autoclave, Swagelok, NPT, WECO union,... As a recorder Job is configured using PC, then the sensor is disconnected and performs the measurement as a stand-alone recorder As a live measurement Job is configured using PC, and sensor performs measurement while still connected to the PC through a coaxial cable Autoclave end connection. Change to suit your pressure line connection type. Sensor connected to a multiline adapter Example of pump truck line autoclave connection Well-head with Frac lines

6 Petroleum technology Pressure Sensor © 2012, all rights reserved Downhole Recorder Deployment As part of a dummy gas lift 1 nose part 1 body part with body adapter At the end of a slickline cable without live communication Mounting a sensor in an unused perforation tool 1 dummy gas lift valve deployment options. Sensor is circled in red. At the end of a slickline cable without live communication

7 Petroleum technology Pressure Sensor © 2012, all rights reserved Gas Lift Valve Deployment Principle Side pocket mandrels allow the deployment and easy retrieval of gas lift valves to control the injection of gas from the casing Gas lift valves can be replaced by Dummy gas lift valves to plug the holes when not in use These Dummy gas lift valves can be turned into measurement locations when one or more of their parts are replaced by a recording sensor Nose part to measure tubing pressure Body part for casing pressure Kickover tool for GLV deployment 1 dummy gas lift valve deployment principle. Casing Tubing Sensor

8 Petroleum technology Pressure Sensor © 2012, all rights reserved Downhole Live Measurement Deployment At the end of a wireline cable used to communicate electrically from sensor to surface Casing is used as electrical ground reference if using an insulated slickline cable Configuration must be defined with client to suit the cable specs. Slickline operation

9 Petroleum technology Pressure Sensor © 2012, all rights reserved Expected deployment with acoustic communication Sensor communicates acoustically with transceiver a few tens of meters from surface Sensor deployed in horizontal segment communicates acoustically with transceiver in the vertical tubing

10 Petroleum technology Pressure Sensor © 2012, all rights reserved Oilfield Wireless Permanent Well Surveillance System

11 Petroleum technology Pressure Sensor © 2012, all rights reserved Key features Surface Wireless Sensor Network Downhole pressure, temperature, flow, fluid density Low power Sensors working on battery ATEX Connected to internet through Stations

12 Petroleum technology Pressure Sensor © 2012, all rights reserved System overview Well Head Module with Battery / Acquisition / Memory / Antenna Downhole Gauge ½ diameter cable RF Up to 300m Client network WIFI Ethernet Station

13 Petroleum technology Pressure Sensor © 2012, all rights reserved The Permanent Gauge Assembly system. There is a room that is taken into sandwitch between the gauge and mandrel which seals with a metal to metal contact. The mandrel (tube on which the gauge is attached) must be designed and manufactured according to customer specifications (diameter production casing diameter, type of steel, thread type).
