... to the annular leaks. The condition of the cement opposite these sands revealed by the ultrasonic imaging log made this the most likely source of the annular gas. However, it was important to verify that the gas was Upper Devonian and not Marcellus in origin. Samples of the gas from both annular leaks were taken...

Paper presented at the Tight Gas Completions Conference, November 2–3, 2010
Paper Number: SPE-137441-MS
... Abstract Stimulation-design considerations usually include things like formation-fracture gradient, reservoir pressure, stress, casing size, perforation schemes, etc. The type of cement that fills the annular space between the openhole lateral and the casing is not typically considered...

... be cemented which has caused constraints on optimal reservoir production. Studies have indicated that conventional cements are one of the primary causes resulting in reduced fracture initiation. Acid-soluble cements have been advocated for use in unconventional gas reservoirs as a means to reduce the rate...

Paper Number: SPE-114866-MS
... from primary cementing operations. A primary cement job design that provides zonal isolation and preserves structural integrity over the life of the well can reduce or eliminate the need for remedial operations. Achieving successful zonal isolation comprises three key mechanisms: Design and delivery...

Paper presented at the CIPC/SPE Gas Technology Symposium 2008 Joint Conference, June 16–19, 2008
Paper Number: SPE-115003-MS
... Abstract While using conventional surface launch cementing plugs during cementing operations performed on large diameter surface pipe, significant costs are incurred during the pumping of cement and displacement fluids because of the large volumes involved in the job. Additionally, high...

Paper presented at the CIPC/SPE Gas Technology Symposium 2008 Joint Conference, June 16–19, 2008
Paper Number: SPE-115004-MS
... Abstract New cement slurries have been developed with significantly reduced greenhouse gas footprints when compared to conventional cement slurries used for oil and gas well cementing operations. The slurries consist of geopolymeric materials exhibiting superior chemical and mechanical...

Paper presented at the SPE Gas Technology Symposium, May 15–17, 2006
Paper Number: SPE-100572-MS
... Abstract A new method of completing multiple-layer tight gas wells is being investigated. The main concept is to place sliding sleeve valves in the casing string and complete the well with normal cementing operations. The sliding sleeves would then be opened one at a time to fracture layers...

Paper presented at the SPE Gas Technology Symposium, April 30–May 2, 2002
Paper Number: SPE-75700-MS
... Abstract Natural gas is one of the cleaner sources of energy, and our challenge is to produce it safely and economically. The extreme operating conditions that occur in gas-storage and gas-producing wells could cause the cement sheath to fail, resulting in fluid migration through the annulus...

Paper presented at the SPE Gas Technology Symposium, April 30–May 2, 2002
Paper Number: SPE-76333-MS
... Abstract This paper documents recent field cases in which attempts were made to mitigate casing vent flows (CVF's) on producing and abandoned wells by incorporating permeability-blocking gels with specialized cement blends. CVF's are defined in this paper as sustained gas pressure...
