Single Well Completion and Management Strategies for Enhanced Recovery of Tight Oil Using Miscible Gas Injection
… on the multiple transverse fracture horizontal well completion design with 50 or more parallel propped hydraulic fractures distributed along a long horizontal well. Less than 10% primary oil recovery from these wells creates a strong incentive for enhancing recovery from tight oil reservoirs in …

Gas Deliverability Using the Method of Distributed Volumetric Sources
… index (PI) is an important indicator of a well?s production capacity. For conventional reservoirs, well productivity is usually calculated using the pressure response of the reservoir in its pseudosteady-state period. There are numerous studies for different well completion schemes which …

General screening criteria for shale gas reservoirs and production data analysis of Barnett shale
… affecting the decision to drill a horizontal well or a vertical well in shale gas reservoirs? 2. Will the shale gas well flow naturally or is an artificial lift required post stimulation? 3. What are the considerations for stimulation treatment design in shale gas reservoirs? A comprehensive …

Variations in mineral abundance within a single horizontal well path in the Woodford Shale, Arkoma Basin, Oklahoma
… to successful exploitation of this resource (Caldwell, 2014; Turner et al., 2015; Wiley, 2015; Zhang et al., 2017). Most prior studies of the Woodford Shale report properties from a single sample collected from a vertical well, which reports these values as a single point source on a distribution …

Descaling petroleum production tubing using multiple high-pressure nozzles
… side effect of jeopardize the integrity of the well completion. Replacement of sand with stealing beads was excellent with good post descaling well completion integrity at the expense of environmental complexity. While the recent single nozzle, solid free aerated jetting descaling technique was …

Analysis of diagnostic testing of sustained casing pressure in wells
Over 8,000 wells in the Gulf of Mexico exhibit sustained casing pressure (SCP). SCP is defined as “any measurable casing pressure that rebuilds after being bled down, attributable to cause(s) other than artificially applied pressures or temperature fluctuations in the well”. The Minerals Management …

Automated Estimation of ISIP and Friction Losses in Hydraulic Fracture Treatment Falloff Data
… recent publication revealed a method to estimate wellbore and perforation friction loss and tortuosity friction loss from hydraulic fracture treatment falloff data. It illustrated friction loss estimations for 270 stages in 16 shale gas wells drilled from the same pad. The resulting estimates …

Analytical and Semi-Analytical Models for Composite Reservoirs with Complex Well Completions
… analytical and semi-analytical models for multi-well performance in petroleum reservoirs, with a view to simulating and forecasting production from unconventional resources. The models will address flow in different reservoir systems (homogeneous reservoirs and composite reservoirs) produced by …

The role of well testing in geothermal resource assessment
… different approaches and methods for analysing well test data to estimate the capacity of a geothermal field are evaluated. The thesis lays emphasis on well completion and flow tests data, and uses the Reykjanes geothermal field in southwest Iceland as an example for the application of the …

Identification of the physical controls on the deposition of Aptian and Albian deep water sands in the Bredasdorp Basin, South Africa
In the petroleum industry, the location of a new well is selected based on several factors, one of which is the presence of reservoir-quality sands. To determine the lateral extent of these sands away from well control, the depositional environment and character of the deposit must be adequately …

Investigating the effect of perforation diameter and carbon dioxide bubble size distribution on heavy oil recovery
… due to shallow pay zones in heavy oil reserves, wellbore heat losses can become excessive, making the process ineffective and uneconomical. For in-situ combustion, high-temperature oxidation reaction model is very challenging to maintain; which inevitably leads to low-temperature oxidation and …
