component monitoring plan two demonstrate mechanical integrity of production <br />wells. <br />1.0 TubinE/Casing Aruiulus Pressure <br />A continuous demonstration of the absence of significant leaks in the casing, or <br />tubing is performed by maintaining and monitoring tubing/casing annulus <br />pressure. Annulus pressure will be maintained sufficient so that annulus water <br />level is below the B-Groove aquifer. Maximum injection pressure is limited to <br />610 psig. Well head monitoring (weekly) of annulus and line pressure, and <br />temperature is accomplished with well head gauges. Continuous readout of well <br />head annulus and line pressure, temperature and flow is provided in the plant <br />control room. Because recovery flow readings are affected by gas bubbles, the <br />flow from the pregnant liquor tank is utilized to adjust calculated recovery flow. <br />Also, down hole pressure is continuously provided in control room from sensor <br />on submersible pumps. <br />2.0 Mud Gel (Casine Pik <br />The second component of the mechanical integrity monitoring plan is to monitor <br />the casing pack around t:he casing. First, weekly visual observation of the <br />casing pack is performed. Second, a more intensive demonstration of the <br />presence of the casing pack is performed by using a temperature logging <br />34 <br />
