3 WELLHEAD MANAGEMENT SYSTEM (WMS) PB/ EN 3 Wellhead Management System ABB tackles the two greatest current challenges in our production industry with an integrated solution that both optimizes wellhead production and chemical usage at the same time in one enclosure. ABB introduces a cost effective package solution for managing your artificial lift & management needs. The ABB Wellhead Management System (WMS) is a single box solution that can allow you to locally and remotely control multiple artificial lift systems. The WMS is built to monitor, inventory, alarm, and control your chemical injection systems with proven measurement techniques and electronic controls. The system is designed for expansion that will also allow you to add our industry leading tools for plunger lift, gas lift, and gas assisted plunger lift in a single unit. The unit is built to scale up from 1 to 4 tanks/wells and can provide you with all of your artificial lift needs. By combining industry leading technologies and field proven applications, you ve never had this much control at your fingertips.

4 4 WELLHEAD MANAGEMENT SYSTEM (WMS) PB/ EN Chemical management and control solution Operational efficiency ABB has engineered an all-in-one solution for managing your chemicals in the field. This solution includes the ability to monitor level and inventory of your tanks through the use of the new ultra-low powered non-contact LST100 level system. Incorporated with monitoring and alarming software, the controller also gives you direct access locally and remotely to the injection schemes, that allows you to effectively and efficiently deliver chemicals to your production. Monitoring and inventory The LST100 is a first of its kind in the oil & gas industry. A low cost monitoring solution that can create real-time inventory of one of the largest lease operating expense (LOE) consumables for nearly all operating assets. Utilizing ultrasonic technology, you now have the ability to monitor and inventory every chemical tank in your field, as well as have alarms in the controller monitoring for leaks, refill alarm set points for re-order of product, tank fill notifications when the product is delivered, and volume calculations. Control Combined with the ABB Well Management System, that includes injections controls, you will have an entire management solution at your fingertips. In addition, an electro-magnetic flow meter verifies accurate chemical volumes down to the milliliter will be delivered according to the ratio you define as the owner. Current injection schemes available are: Manual mode Manual setpoint for Chemical injection rate (Qts/D) which sets the chemical injection target rate (or setpoint). The tuning logic will then adjust pump injection time (secs) based on current measured chemical injection flowrate to meet the chemical injection target rate every minute. Ascend mode Automated chemical injection based on direct scaling between user input chemical injection volume max/min limits (Qts/D) and user input flowrate max/min limits (Qts/D). The tuning logic will then adjust pump injection time (secs) based on current measured chemical injection flowrate to meet the auto scaled chemical injection target rate every minute. Descend mode Automated chemical injection based on inverted scaling between user input chemical injection volume max/min limits (Qts/D) and user input flowrate max/min limits (Qts/D). The tuning logic will then adjust pump injection time (secs) based on current measured chemical injection flowrate to meet the auto inverted scaled chemical injection target rate every minute.

5 WELLHEAD MANAGEMENT SYSTEM (WMS) PB/ EN 5 Artificial Lift application Intelligent optimization Plunger Lift Application Based on the simple idea presented in the Plunger Lift Circle of Life below, the system will react according to the well s ability to produce. Set the expected time for the Plunger Fall Delay and wait for the plunger to reach bottom. Set one or more conditions in the Waiting to Open phase and the system will automatically open when conditions are optimum. Select one option or all, the first one to happen will move you to the next step. You can choose options such as timer based control to more advanced pressure control. Once the plunger is up, there are a variety of options that will assist in determining if the optimum condition has been achieved, from advanced casing pressure monitoring to traditional rate controls. When combined with the ABB Plunger Analysis Software, you will have the most powerful, intelligent, and cost effective solution available. Valve closed During the Plunger Arriving state, simply set the normal arrival windows according to your depth and fluid load. If adjustments are needed, the system will help you during the next cycle to achieve the optimum balance.

Gas lift Critical rate based injection Auto inject based on critical Dynamic control based on a critical multiplier (Turner flow rate calculation) to maintain flow above critical rate. Calc: MCR-ProdRate=Target Rate Inject Intermittent injection Manual control over injection rate, injection period, and off time. Step rate testing Control injection tests using varying injection rates and injection periods to determine the optimal multiplier to keep flow above critical rate. If production rate rises above critical rate, injection rate = 0 Well in Freeflow condition ABOVE critical rate Production rate falls below an auto calculated Critical rate Critical Production = Deficiency in gas is injected until production rate is back above critical rate If production rate rises above critical rate, Injection Rate = 0 If production rate rises above critical rate, injection rate = 0 If production rate < critical rate: BEGIN: Inject X rate calculated difference critical production Multiple mode gas lift options Gas lift critical mode: est:
