... As stated above, drilling across fractured carbonates may lead to a significant exposure due to lost circulation. To quantify that statement, the analysis of completed wells on several fields was performed to identify the amount of fluid lost downhole while drilling from the drilling fluid...

... Abstract Lost circulation is a major contributor to non-productive time (NPT). Any efforts to better understand the factors that lead to it and subsequently identify a suitable cure will translate to tremendous savings of time and money for operators. Conventional materials such as calcium...

... in two options. The first one – horizontal conventional drilling. As far as the bit penetrates into the reservoir we are seeing SPP (Stand Pipe Pressure) decrease which means we have total lost circulation. There was only one means for resolving this problem – using LCM (Lost Circulation Material). Due...
