  • Testing Compressive Strength with the Ultrasonic Cement Analyzer

    Cement in an oil well needs to be able to resist the forces found in the formation in order to protect the steel casing around which it is placed. The cement sheath is also required to support the weight of the casing as well as resist perforation operations conducted by wireline operators in preparation for fracturing and stimulation activities. Cement needs to develop an adequate level of compressive strength in order to meet these requirements. Cement compressive strength describes the ability of hardened cement to resist crush force. Laboratories have multiple options to measure the compressive strength development of a cement design. The most practical and efficient method to accurately calculate the compressive strength is to use an Ultrasonic Cement Analyzer (UCA). The UCA works by sending a continuous sound pulse into the cement slurry. As the cement hardens, the sound pulse tra ...

  • Testing the Lubricating Properties of Drilling Fluids

    The lubricating properties of drilling fluids are an important factor in well design. Deviated holes are particularly susceptible to excess drag between the drill string and casing. Serious casing wear can also occur in deep and ultra-deep wells and is further complicated by tripping in and out of the hole. The challenge for mud engineers is to design a drilling fluid system that adequately lubricates the drill string without compromising other physical properties such as density, rheology, and filtration. To test the drilling fluid, engineers use a specially designed Lubricity Tester. This instrument simulates the rotation of the drill string and the pressure of the drill pipe against the casing. A stationary block is pressed against a rotating ring while both are submerged in the test fluid. The control board measures the torque necessary to turn the ring at a constant speed and conve ...

  • Preparing Cement with a Constant Speed Mixer

    Cement slurries used in the oil field are dynamic fluids with complex chemistries. Laboratories tasked with the development of slurries used for cement pumping operations strive to prepare these mixtures under conditions that reflect those found out in the field. With the replication of conditions that are as close as possible to those found out at the wellsite, technicians are able to make accurate predictions the behavior of cement slurries under those same conditions. The most basic way to ensure that lab-prepared slurries match the performance of field-prepared counterparts begins with a properly mixed slurry. Cement laboratories use a constant speed mixer to ensure that mixed cement slurries are a homogeneous blend. The proper amount of mixing energy ensures that individual cement grains are completely surrounded by water which kicks off the cement hydration process. Laboratory tec ...

  • Measuring Shale Swelling

    Shale swelling is a major cause of wellbore instability. It can lead to a variety of problems, such as hole sloughing, pipe drag, bit balling, stuck pipe, or other “gumbo” related issues. Shale swelling is caused by clay (one of the major components of shale) absorbing water, usually from drilling fluid. The proper drilling fluid additives can mitigate shale swelling and prevent the loss of the entire drilling operation. The OFITE Dynamic Linear Swellmeter measures the interaction between drilling fluids and mineral samples containing clays. This instrument can test up to four (expandable to eight) samples simultaneously and compare the results over time. Each test consists of a cylindrical wafer of compressed bentonite, rev dust, or downhole sample. The wafer is constrained around its circumference and exposed to fluid. As the clay reacts to the fluid, the wafer can only expand linearl ...
