• Mitigating Gas Migration by Measuring Static Gel Strength of Well Cement

    Cement slurries that are placed in gas bearing formations as part of the well completion process are at risk of gas migration under the right conditions. Gas migration refers to the annular flow of natural gas from the formation up through the cement column. As the gas moves through the cement matrix, it carves a channel that becomes permanent once the cement sets. This permanent channel becomes a conduit that allows for natural gas to continuously bleed from the formation. After cement placement operations have stopped, the cement slurry begins to develop gel strength under static conditions. The amount of gel strength development and the speed at which it occurs are two of the main factors that describe a cement slurry’s ability to resist gas intrusion. Generally, gas intrusion begins when cement slurries develop 100 lbf/100 ft2 (48 Pa). Gas intrusion ends when the cement develops 500 ...

  • Pressurized Consistometers Provide Valuable Information About Cement Thickening Time

    For oilfield service companies trying to cement a well, the thickening time of the cement slurry is the critical slurry property to control. A typical cement job requires the slurry to be mixed at the surface and pumped downhole. Cement slurry that sets up too soon leads to a Cement Left In Pipe (CLIP) situation. A CLIP occurs when cement fluids set up inside the steel casing during placement. Costs associated with both the well and nonproductive time is significant. Slurries with extended thickening times lead to costly extended time on station as the drilling rig is required to remain on station in order to provide support for the casing. In a worst case scenario, the well is at risk of complete loss of control as the cement is unable to maintain both zonal isolation and well integrity. Laboratories need the capacity to gauge the performance of the cement slurry in order to accurately ...

  • Multi Unit Retort Saves Valuable Lab Space

    The Retort measures the percentage (%) of oil, water, and solids in a sample of drilling fluid or cuttings. The results from a Retort test are essential to properly controlling mud properties such as rheology, density, filtration, and salinity. It is also important for evaluating viscosity control and solids control equipment. Retort Kits have historically been large and bulky, taking up valuable laboratory space. The OFITE Multi Unit Retort combines five 50 mL Retort units into a single enclosure with a single electrical inlet. It saves space on the counter and only uses one electrical outlet. It also features a convenient stand for 50 mL Receiver Tubes (JP Tubes) and independent temperature control for each unit. The included software records and graphs the temperature of each unit over time. ...

  • Pressurized Viscometers for Fracturing Fluids

    Fracturing fluids are viscous mixtures of water and additives that are pumped at high pressures into an underground oil or natural gas formation. They are designed to fracture the formation and carry proppant into the newly formed cracks. Once the proppant is placed, the fracturing fluid flows back to the surface for disposal by the service company. Proppant left inside the fractures provides liquid hydrocarbons an easy path to flow out of the formation and up to the surface. The fracturing fluid is the key component to the stimulation process. It needs to have enough viscosity to carry the proppant, but it must also "break" and lose viscosity so that it will flow back to the surface without blocking the production of hydrocarbons from the formation. The Pressurized Viscometer is the essential tool service companies use to finalize the fracturing fluid design. A Pressurized Viscometer a ...
