Title: Innovations of Jafar Abdollahi

Introduction

Jafar Abdollahi is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of drilling technology, holding a total of five patents. His work focuses on innovative solutions for mud loss treatment during drilling operations.

Latest Patents

One of his latest patents is a tool designed for the remediation of lost circulation while drilling. This mud loss treatment drilling tool features an upper tool joint connected to a lower end of a drill pipe string. It includes one or more tanks with a through channel for drilling fluid flow and a lower tool joint connected to a Bottom Hole Assembly (BHA) that comprises a drill bit. The tank is arranged to hold a swellable sealant agent, which mixes with water to swell. When undesired mud loss is detected, the tool flushes the swellable sealant agent into the through channel, allowing it to react and swell, effectively blocking the fracture to stop the mud loss.

Another significant patent by Abdollahi is the at-the-bit mud loss treatment method. This method involves a drilling tool main body with a through bore connected to a wired drill pipe string. The main body is equipped with an annular tank containing a swellable sealant and a valve to an outlet to the through bore. A control system receives sensor signals and runs a monitoring algorithm to detect mud loss states during drilling. If a mud loss state is detected, the system commands the valve to open, ejecting the swellable sealant into the through bore.
