Investigation of Efficiency Improvements During CO2 Injection in Hydraulically and Naturally Fractured Reservoirs

The objective of this project was to perform unique laboratory experiments with artificial fractured cores (AFCs) and X-ray CT to examine the physical mechanisms of bypassing in HFR and NFR that eventually result in less efficient CO2 flooding in heterogeneous or fracture-dominated reservoirs. This report provided results of the second semi-annual technical progress report that consists of three different topics

Preferred Waterflood Management Practices for the Spraberry Trend Area

The objectives of this report was to propose the location of new injection wells, to review wellbore status in Germania unit and to forecast the incremental oil recovery based on waterflooding performance in other waterflood pilot area in order to demonstrate the benefit of waterflooding in Germania unit area

Cardiac Tamponade Following Penetrating Mediastinal Injuries: Improved Survival With Early Pericardiocentesis

Cardiac tamponade was diagnosed in 197 patients admitted over 20 years (1955-1974) to the Charity Hospital of New Orleans, for emergency treatment of penetrating mediastinal injuries. Of the 197, 174 definitively treated patients followed one of three patterns of management: 96 had OR thoracotomy, 68% were unstable, and preoperative pericardiocentesis reduced mortality from 25 to 11% (p \u3c 0.01); 44 had emergency thoracotomy, 91% were unstable, and prethoracotomy pericardiocentesis decreased mortality from 94 to 63% (p \u3c 0.05); 34 patients primarily with isolated stab wounds, were treated nonsurgically with pericardiocentesis and observation, only 50% were unstable and there was 15% mortality. Recurrent tamponade did not significantly increase overall or operative mortality in patients with pericardiocentesis. Recommendations: early, even presumptive, diagnosis of tamponade; immediate pericardial decompression via pericardiocentesis; and rapid transfer to OR for thoracotomy or sternotomy and cardiorrhaphy with continous pericardial decompression via intrapericardial catheter
