Identifying drill bit failure during oil well drilling is vital to prevent expensive downtime and ensure operational safety. Employing various methods can enhance your ability to identify potential issues as shown below. Real-time drilling data:Rate of Penetration (ROP): A sudden decline in ROP, particularly when compared to the planned rate, may indicate bit wear or […]

The caliper probe, a simple mechanical device, whose main functionality is to measure the internal diameter of a borehole or casing string within a borehole. Another purpose of a caliper arm is to push a section of a probe against the side of the borehole (for example density logging), known as sidewalling. Additional data measured […]

Aims to recover wells from equipment lost and/or trapped in wells to the desired conditions by utilizing various types of “fishing rods”. Fishing rods can be used during drilling operations and during service operations of production wells. In drilling operations, equipment that is lost and/or trapped in the wellbore (fish) must be recovered as quickly […]

The term Slickline relates to the use of a wire or braided line to convey downhole tools or equipment in a wellbore. The first use of wire in a wellbore was as a measuring device. In the construction of the early wells dug by hand, sticks were used to measure depth. The stick was laid […]

Wireline measurements, the logging tool (or sonde) is lowered into the open wellbore on a multiple conductor, contra-helically armored wireline cable. Once the tool string has reached the bottom of the interval of interest, measurements are taken on the way out of the wellbore. This is done in an attempt to maintain tension on the […]

In normal situations, the valve seat in a mud pump plays a pivotal role in ensuring the efficient movement of drilling mud within the oil and gas industry. Its primary function is to form a tight seal with the valve, thereby controlling the flow of the slurry or drilling mud. Operation of valve seat:Directional Control: […]

A tricone drill bit is a type of rock drilling tool that consists of three rotating cones with sharp teeth. Each cone is equipped with bearings that allow it to spin independently, enabling the bit to effectively penetrate hard rock formations. The teeth on the cones are designed to cut through the rock, while the […]

Varco Top Drive Drilling System is more than a concept. It is a proven, practical drilling system that has been setting drilling records and producing profits for operators. Time savings have averaged over 25% on the wells drilled with this system. In addition to reaching TD ahead of schedule, the operators feel that the ability […]

Structure Characteristics of Drilling PDC BitsPDC bit is composed of the a bit body, PDC cutting teeth and a nozzle. According to different structures and drill bit manufacturing processes, the drilling PDC bits are divided into two series: steel body and matrix body. The whole bit body of rigid drilling PDC bit is made of […]

Slips In Drilling Rigs device used to grip the drillstring in a relatively nondamaging manner and suspend it in the rotary table. This device consists of three or more steel wedges that are hinged together, forming a near circle around the drillpipe. On the drillpipe side (inside surface), the slips are fitted with replaceable, hardened […]
