... to 175 deg C) to surface will resulted in significant heat transfer to adjacent casing & its annulus fluids, and lead to annular pressure build-up (APB). High APB will lead to loss of well integrity via 13-3/8" intermediate casing burst and 9-7/8" production casing collapse if left unmitigated...

... Abstract The average geothermal gradient in the subject deepwater field in Nigeria is 4.37 °C/100 m, nearly twice the gradient in most fields. As a result, the magnitude of the expected annular pressure build-up (APB) during steady state production is large enough to threaten well integrity...

... Abstract Annular Pressure Build-up (APB) is caused by heating of the trapped drilling fluids (during production) which may lead to burst/collapse of the casing or axial ballooning, especially in subsea HP/HT wells. The objective of present paper is to apply machine-learning tools to increase...

... Abstract Annular pressure buildup (APB) is a major concern in high pressure, high temperature (HP/HT) well design. High temperature hydrocarbon production increases wellbore temperature significantly, inducing a large APB as a result of annular fluid thermal expansion. Vacuum-insulated tubing...

... Abstract A wide variety of annular pressure buildup (APB) mitigation techniques have been deployed in the past two decades. In the early 2000s, BP focused efforts on the development and implementation of rupture disks, nitrified foam spacers, syntactic foam modules and vacuum insulated tubing...

... Abstract Manufactured to burst/collapse at a specific pressure difference and installed in the casing wall, a rupture disk is a common device used to mitigate annular pressure buildup (APB) and to protect casing strings. This paper focuses on the modeling and simulation of the effects...

... Abstract Subsea wells use Annular Pressure Build-up (APB) mitigation devices to ensure well integrity. Type I mitigation techniques control APB by reducing radial heat loss from the production tubing to the wellbore. Type II techniques work by controlling the stiffness (psi/°F) of an annulus...

... with potential or identified Annulus Pressure Buildup (APB) problems, especially at offshore fields. Historical failure examples happened at the Marlin field and at the Ponpano A-31 well, both in the Gulf of Mexico. The objective of this article is to present several alternatives for mitigating this problem...

... Abstract Biocorrosion of metal pipelines in the oil and hydrocarbon industry is frequently linked to the presence of Sulfate Reducing Bacteria (SRB) and Acid Producing Bacteria (APB). Suggested mechanisms of SRB induced corrosion are an accumulation of corrosive metabolites like hydrogen...

... Abstract Annular pressure build up (APB) is an important problem in the area of well design. Different solutions have been proposed to mitigate APB, including vacuum-insulated tubing, silicate foam wellbore insulation techniques, and insulating with completion (packer) fluids. However, proposed...
