Squeeze Cementing Operations

Abstract

AHSTRACT Laboratory and field testing of various squeeze cementing techniques and materials revealed that many improvements could be made in squeeze cementing operations. The use of a slowpumping squeeze cementing procedure permitted the control of the quantity (If . cement displaced into a formation and aided in obtaining a high final squeeze pressure. Field testing indicated the desirability _ ,of .obtaining high _.final squeeze pressures, the need for improved formation breakdown fluids, and the necessity of controlling the pressure differential during testing after a squeeze job.

Interactions of Hydraulic Fractures With Grain Boundary Discontinuities in the Near Wellbore Region

“…The propagation direction of hydraulically induced fracture was contested at some point (Harrison et al., 1954; Reynolds et al., 1961) whether it is horizontal along a bedding plane lifting the overburden (Howard & Fast, 1950) or orthogonal to the minimum principal stress (Hubbert & Willis, 1957). However, a number of theoretical analyses and experiments demonstrated that the plane of hydraulic fracture propagation is orthogonal to the minimum principal stress (Harrison et al., 1954; Hubbert & Willis, 1957).…”

Proactive control of cresting in homogeneous oil reservoirs: an experimental study

“…Inflow control devices (ICDs) have also been used but cannot completely stop the influx of water (Schevchenko 2013). In addition, the idea of injecting a ''pancake'' of cement just below the completion interval to prevent the vertical/upward flow of water into the wellbore was reported (Howard and Fast 1950;Makinde et al 2011). The feasibility of downhole water loop (DWL) installation to produce water-free oil in reservoirs with a bottom aquifer was investigated (Jin et al 2010).…”

Modifying subterranean fluid flow patterns using barriers to improve pre-drainage in coal mining

“…In production related applications, most are directed at modifying vertical flow of water, or coning, in oil or gas reservoirs (Azari et al, 1997). In addition, there has always been a large use of cementatious grouts, chemical grouts, and polymeric treatments to selectively eliminate perforated sections in cased hole environments, from which undesirable water or gas influx may be entering the wellbore and negatively impacting the desired well productivity (Howard and Fast, 1950;Jurinak and Summers, 1991).…”
