انجام عملیات شکست هیدرولیکی سهم قابل توجهی در افزایش تولید نفت و گاز در دنیا داشته است. اگرچه بیش از 60 سال است که در صنعت نفت دنیا شکست هیدرولیکی با موفقیت اجرا می شود، اما در ایران گزارشی از اجرای موفق این عملیات ارایه نشده است. همین امر لزوم توجه هر چه بیشتر دانشمندان ایرانی به این مهم را آشکارتر می سازد. در مدل ایجاد شده توسط نرم افزار آباکوس، مدل سازی چاه به صورت استوانه ای درون بلوک سه ب...

Abstract Estimation of a reservoir’s production potential, well placement and field development depends largely on accurate modeling the existing fracture networks. However, there is always significant uncertainty associated with prediction spatial location connectivity networks due to lack sufficient data model them. Therefore, stochastic characterization these fractured reservoirs becomes nec...

Despite appropriate management of distal radius fractures, TFCC tears and DRUJ instability in the acute setting, a subset of patients will have ongoing pain or instability of the DRUJ. Ongoing instability is thought to eventually lead to pain, loss of motion and degenerative changes due to alterations in normal kinematics of the joint, although there is little in the literature to support this ...

BACKGROUND This paper presents the model and results to evaluate the use of teriparatide as a first-line treatment of severe postmenopausal osteoporosis (PMO) and glucocorticoid-induced osteoporosis (GIOP). The study's objective was to determine if teriparatide is cost effective against oral bisphosphonates for two large and high risk cohorts. METHODS A computer simulation model was created t...

The authors report on an important differential diagnosis of back pain in a pregnant woman caused by an atraumatic insufficiency sacral fracture. This diagnosis is a rare entity in pregnant patients and may often be overlooked due to nescience by the treating physicians. The authors discuss the diagnostic and treatment options in undisplaced sacral fractures and their successful natural treatme...
