Abstract This paper presents the results of laboratory static and dynamic tests on casing-cement-rock systems exposed to axial loads under ambient conditions. A new testing method has been developed. The casing-cement-rock system mostly fails due to tension and shear stresses. In various applications such as HPHT, deep-water, (steam) injection or geothermal wells, the cement-casing bond is exposed to cyclic thermomechanical loads resulting in casing elongation, contraction, expansion and subsequently in cyclic radial and axial stresses at the cement-casing-rock system. Cement is a brittle material which can fail when subjected to repeated application of stresses lesser in magnitude than the statically determined strength. A novel atmospheric test cell has been designed and constructed. In order to achieve the fatigue limits of the cement-casing bond, a set of testing procedures has been established. Several tests are conducted to evaluate de-bonding. The focus on de-bonding is achieved by allowing the casing to move through the test while preventing any cement movement. Thus, when a force is applied in the axial z-direction - either the casing is pulled out (tension) or pushed down (compression) - the casing has enough space to move in both directions. The advantage of this testing method is that different stress ratios can be applied during the test.

Offshore Production Platforms

Gas-liquid downward flow is frequently encountered in hilly-terrain pipelines, downcomer pipes extending from offshore production platforms to sea floors, and steam injection wells in thermal enhanced recovery operations. Since the gravitational and frictional terms in the total pressure gradient equation for downward flow have opposite signs, gas-liquid downward flow in inclined and vertical pipes may experience either pressure loss or pressure gain, depending on flow rates, pipe geometry, and fluid properties. A mechanistic model for the pressure loss/gain boundary of gas-liquid downward flow in inclined and vertical pipes is developed in this work and is verified with available experimental results. The effects of pipe inclination angle, inside diameter, wall roughness, and fluid physical properties on the pressure loss/gain boundary are presented. [S0195-0738(00)00302-2]

Care Costs

Surgical wound complications remain a major cause of morbidity; although usually not life threatening, they reduce the quality of life. They are also associated with excessive health care costs. Wound healing is affected by many factors – wound characteristics, infection, comorbidities and nutritional status of the patient. In addition, though, psychological stress and depression may decrease the inflammatory response required for bacterial clearance and so delay wound healing, as well. Although the patient´s state of mind can be influenced only to a certain extent, we should nevertheless stick to ERAS (Enhanced Recovery After Surgery) guidelines and try to diminish fear and anxiety by providing enough information preoperatively, pay due attention to postoperative analgesia and seek to provide an agreeable environment.
