Summary In this paper we present a field case based upon a reservoir operated by Statoil in the Norwegian Sea. The case concerns a series of water injectors-i.e., both subsea and platform-that underwent extreme losses of injectivity over short period

SummaryThis paper presents an overview of a vast research project called Formation Evaluation 2000, which was undertaken by Agip SpA and was aimed at characterizing in real time the formations encountered during drilling by means of measurements on d

Experiments on Pietra Leccese chalk revealed that many of the material parameters describing its mechanical behaviour, such as the Young's modulus, the uniaxial compressive strength and the plastic yield stress, depend strongly on the water saturatio

Summary Sonic while drilling has long been considered a major goal by the industry because of its potential applications: real-time determination of pore pressure and overburden gradients, improved lithology change determination, seismic calibration,

Summary We mapped the hardness of the rock surrounding shaped-charge perforations with an indentation technique based on the Brinell method. We fired conventional perforators (3.2-g explosive weight) into a friable sandstone (approximately 6.9 MPa un

The role of shale behaviour in borehole instability is classically explained by the high reactivity with water, resulting in swelling, slaking, weakening, etc. However, laboratory experiments are carried out on shale samples whose total saturation is

In conclusion, the conceptual results presented in this note show that attempting to model stress development around an underground excavation using only a simple constitutive model can give misleading results. Two constitutive models, written within

Sand Management is an operating concept where traditional sand control means are not normally applied, and production is managed through monitoring and control of well pressures, fluid rates and sand influx. In the last four years, Sand Management in
