Methodology to Compute Mathieu Functions for Arbitrary Large Parameter q and Its Application to Pressure Transient Analysis
Autor: P.J. van den Hoek
Publikováno v: Proceedings.
Mathieu functions are widely used for the solution of boundary value problems in elliptical systems. In spite of their common use, they are notorious for their inherent instability at high (absolute) values of the parameter q. In this paper we presen

A Simple and Accurate Description of Nonlinear Fluid Leakoff in High-Permeability Fracturing
Autor: P.J. van den Hoek
Publikováno v: SPE Journal. 7:14-23
Summary Fluid leakoff in hydraulic fracturing is conventionally described using the well-known linear (Carter) model. Although this works well in low-permeability formations, the linear leakoff assumption may lead to sometimes significant overestimat

Publikováno v: SPE Drilling & Completion. 15:274-283
SummaryLong-term stability of horizontal wellbore completions with uncemented liners in weakly consolidated to unconsolidated sandstone formations (e.g., the Gulf of Mexico and Nigeria) remains an area of concern. In this paper we present the results

Simulation of Produced Water Reinjection Under Fracturing Conditions
Autor: Ghassem Gheissary, T. Matsuura, P.J. van den Hoek, Michiel de Kroon
Publikováno v: SPE Production & Facilities. 14:166-176
SummaryAn essential difference between conventional waterflood fracturing and unfiltered produced water reinjection (PWRI) under fracturing conditions is that in the latter case, the fracture conductivity cannot be assumed infinite anymore as a resul

Injection Fall-off Interpretation from Fractured Injectors
Autor: P.J. van den Hoek
Publikováno v: Proceedings.
We performed numerical simulations of injection fall-off (IFO) testing for both water and (non-Newtonian) polymer in which the gradual closure of the induced fracture is explicitly included. A large variety of induced fracture sizes and shapes was in

Application of Injection Fall-Off Analysis in Polymer flooding
Autor: T.G. Sorop, Marcel Zwaan, Hassan Mahani, Faisal Saadi, S.. Sen, Khalfan Shuaili, P.J. van den Hoek, A. D. Brooks
Publikováno v: All Days.
Polymers exhibit non-Newtonian rheological behavior, such as in-situ shear-thinning and shear-thickening effects. This has a significant impact on pressure decline signature as exhibited during Pressure Fall-Off (PFO) tests. Therefore, applying a dif

Publikováno v: SPE Production & Facilities. 9:239-246
Summary We conducted fracture propagation experiments on blocks of cement paste, cement paste with sand, and a tight outcrop sandstone rock. A novel acoustic monitoring system was developed for measuring the fracture profile and radius during the tes

Theoretical and experimental investigation of rock dilatancy near the tip of a propagating hydraulic fracture
Autor: J. T. M. van den Berg, P.J. van den Hoek, J. Shlyapobersky
Publikováno v: International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts. 30:1261-1264
This paper quantifies the effect of Leading Edge Dilatancy (LED) on Net Fracture Pressures (NFP) in the hydraulic fracturing of reservoir rock by simulating fracture growth with an elasto-plastic Finite Element (FE) description. Rock properties were

Investigation of the dynamics of the O2/Si(001) adsorption system by small-angle ion-surface scattering

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 48:339-343
The small non-adiabaticity associated with the slow collision of a 450 eV to 3 keV O 2 + beam incident at 5° to a carefully flattened Si(001) surface was used to probe the adiabatic potential energy surface for the O 2 /Si(001) adsorption/reaction s
