... ( Elmer 2017 ), the authors of this paper proffered that Annular SPHPGL could lift large liquid volumes. Further, this lift method was potentially a competitive alternative to failure prone Electric Submersible Pumps (ESPs) which are often used early in the life of horizontal wells to produce at high...

... fracturing treatment designs. Abstract Engineers commonly expect symmetric fracture wings in multiple transverse fracture horizontal wells (MTFHWs). Microseismic surveys have shown asymmetric hydraulic fracture grow away from the recent fractured wells and grow towards previous produced wells. It might...

... in a challenging deep and hot environment requiring hydraulic fracture stimulation. Recently, horizontal well trials started taking place in two of the structures aiming for testing efficiency of this type of completion and further evaluation of formation deliverability. Successful completion of horizontal...

Multistage hydraulic fracturing in horizontal wells through multiple reservoir sands allows production of hydrocarbon from multiple reservoirs at the same time while improving the hydrocarbon flow significantly in low-permeability formations. As drilling activity in the Third Bone Spring...

Paper Number: SPE-173593-MS
... Abstract The Woodford shale formation of Oklahoma is difficult to evaluate and forecast for production. Horizontal wells can often be inconsistent with offset wells, either in production rate or in expected ultimate recovery. The costs of these wells can vary greatly based on the cost...

Paper Number: SPE-173633-MS
... Abstract Simultaneous multiple fracturing is a new hydraulic fracturing technology by fracturing two or more parallel horizontal wells simultaneously to improve oil and gas production. Quite a few simul-fracs have been down and some of them are successful in the industry up to now. Using...

Different borehole conditions, such as hydraulically fractured vertical wells, horizontal wells, and mixed borehole conditions, are considered. Multivariate linear regression analysis was used to determine interwell...

..., both reservoirs should be depleted relatively identical. Figures 5 and 6 represent the reservoir models that have been applied for the horizontal and vertical wells. By performing Nodal Analysis for horizontal wells, it was realized that the well cannot flow without applying artificial lift, even...

Paper Number: SPE-164513-MS
... Abstract In North America the primary drilling and completion activities are for horizontal wells. Inclined wellbores make it more difficult to get high quality cement log data and, hence, additional information is necessary for proper execution and evaluation. These guidelines intend...

... Abstract Horizontal well completion and stimulation technologies are the keys to successfully develop shale gas reservoirs. The impacts of hydraulic fracture parameters, hydraulic fracture induced complex natural fracture system, and rock characteristics to well performance need to be clearly...
