An innovative sand control technology is being developed that has the capability to conform to the wellbore and apply a positive stress on the formation face. The technology is a porous shape memory polymer with the capability to change geometric shapes. This shape memory polymeric material is molded to an initial geometric shape. The material is then heated and compacted to a smaller volume, 25% of initial volume compacted, for run-in hole (RIH) geometry. As any shape memory polymer, it can recover its original shape if heated close to its Tg, or by temporarily chemically shifting its Tg to a new lower temperature that of its original Tg. This paper will present the results of additives added to completion fluids, giving the final fluid composition the ability to activate the polymer to its original shape, and simultaneously clean up the filter cake left by the drilling fluid before the polymer reaches the wellbore. The additives are delayed so that the filter cake retains fluid loss properties during activation, but breaks shortly after the polymer reaches the gauge-hole, or has enough treatment caused by the one-trip fluid there by allowing for production at maximum flow rates. At the same time that the filter cake is being treated, a second additive is acting as a plasticizer on the shape memory polymer to activate it, forcing the polymer to recover its original shape. The results are measured via two test methods, one that monitors and records the activation time of the polymer to gauge hole, and a second method that measures the fluid loss properties of the filter cake ensuring that the filter cake is stable for the time required for the shape memory polymer to reach gauge hole.

Casing Drilling, an innovative process for simultaneously drilling and casing a well, is emerging as viable technollogy for the twenty-first cenury. The concept builds upon experience gained drilling liners to bottom in troublesome holes. With the advent of dependable top drive systems, wireline retrievable bottom hole assemblies, PDC bits, and high torque connections, it is possible to simultaneously drill and case a complete well using casing as the drill-string. BP used the Casing Drilling process in Wyoming to drill both the surface and production casing intervals for five gas wells. These wells range in depth from 8,200 to 9,500 feet. This paper provides a case history discussion of critical issues that were encountered and resolved during the planning and sperations phases of the project.

This research seeks to venture into optimal well and fracture design via reservoir modeling, simulation and economic analysis in an attempt to discover, analyze, interpret and present the best ways of maximizing hydrocarbon (natural gas) production from the Utica shale which is a relatively new reservoir. Within is found research work aimed at propagating the discovery of methods that can enhance production from the Utica shale through reservoir simulation. Furthermore, the Utica shale is studied to determine the effects of various parameters on cumulative natural gas production through the comparison of natural gas production in deep and thick Utica formation sections from various well and facture designs, analysis of various fracture designs and economic analysis to determine an optimal design. The objective of this study is to compare and contrast the gas production from various well and fracture designs in deep and thick Utica formation sections. Along with the horizontal well study, the effects of varying parameters such as fracture half length, number of fracture treatments and horizontal wellbore lateral lengths on gas production in these shale wells would be analyzed, interpreted and presented. Economic evaluations of various well designs would also be analyzed, interpreted and presented. This project focuses only on horizontal wells since it has been proven time and again that horizontal wells tend to be more viable in shale when compared to vertical wells. Furthermore, an economic analysis would then be conducted to discover the optimum design for Utica shale wells. This research is of the utmost importance and holds the unique prestige of being a fore runner in the research of the Utica shale play productivity via the study of stimulated reservoir volume analysis, optimal well & fracture design and detailed economic analysis. This research presents results for the Utica shale play productivity via the SRV analysis, optimal well & fracture design and detailed economic analysis.
