A system and method are used in drilling a borehole in a formation. A trip to move a drillstring in the borehole is identified, where the trip is expected to produce a piston effect that changes a downhole pressure of the fluid in the borehole. A peak speed to move the drillstring in the borehole is calculated for the trip, and adjustments to a surface backpressure of the drilling system is calculated for the trip at the calculated peak speed to keep the downhole pressure within a tolerance of the formation. The drillstring is moved in the trip according to the calculated peak speed, and the downhole pressure change produced by the piston effect is counteracted by automatically adjusting the surface backpressure according to the calculated adjustments.

For a wellbore drilled in low or subnormal pressure reservoirs, a static loss rate of drilling fluid is monitored within a limit of a drilling rate. Reaching the limit, the annulus is closed off to returns, or the annulus remains open to atmosphere at surface. Operations may not be able to keep the annulus filled with a mud cap so pressurized mud cap drilling cannot be sustained. Instead, an initial fluid level of the mud cap is defined in the annulus. Drilling with the mud cap then involves: pumping a sacrificial fluid through the drillstring without returns to surface, and monitoring the initial fluid level in the annulus to detect a change. Monitoring uses downhole instrumentation to measure pressure, temperature, and gas level of the mud cap. In response to the change, the drilling can be further controlled, including stopping the drilling, turning off pumps, and possibly bullheading the well.

DRILLING SYSTEM AND METHOD USING CALIBRATED PRESSURE LOSSES
Control of a drilling system drilling a wellbore is improved using a hydraulic model corrected for pressure losses. A surface backpressure of the outlet and a standpipe pressure of the inlet are measured with sensors in the system. An estimate of the standpipe pressure is calculated based integrating from the measured surface backpressure back to the inlet in the hydraulics model. The pressure loss increment in the hydraulics model is calculated based on a difference between the measured and estimated standpipe pressures. Meanwhile, a parameter in the drilling system is monitored during drilling so the parameter can be adjusted at least partially based on the hydraulics model corrected for the pressure loss.

LOAD BALANCED POWER SECTION OF PROGRESSING CAVITY DEVICE
A progressing cavity device operates as a motor to impart torque to a bit. A stator of the device defines an internal profile having uphole stages with a first dimension being less than a second dimension of downhole stage. A rotor has an external profile with a constant outer dimension along its length. Disposed in the stator, the rotor defines cavities with the stator and is rotatable with pumped fluid progressing in the cavities from the uphole to downhole to transfer torque to the drive toward the downhole end. Although the rotor is subjected at the downhole end to a reactive torque from the bit, the interference fit of the rotor's constant dimension with the stator's downhole stages is less than with the uphole stages, which can mitigate issues with heat buildup in the downhole stages. The device can also operates as a progressing cavity pump.

BOTTOM HOLE ASSEMBLY FOR CONFIGURING BETWEEN ARTIFICIAL LIFT SYSTEMS
A wellbore completion is configured for multiple forms of artificial lift. A downhole assembly on production tubing defines a production port communicating a throughbore with the wellbore annulus. A bypass, such as a snorkel or riser tube, on the assembly also communicates the throughbore between the packer and the production port with the annulus. A packer on the assembly seals in the annulus downhole of the production port and bypass. The assembly can then be configured for any selected artificial lift. To do this, at least one isolation, such as a sleeve insert, a sliding sleeve, a check valve, or a rupture disk, selectively prevents/allows communication via one or both of the production port and the bypass as needed. Additionally, removable lift equipment, including jet pump, gas lift valve, plunger assembly, rod pump, piston pump, or standing valve, is selectively inserted into the assembly's throughbore as needed.
An anchor for securing a well tool can include a longitudinally extending central axis, an outwardly extendable grip member, and a mechanical linkage including multiple pivotably connected links. The links pivot relative to each other in a plane laterally offset from the central axis. A method of anchoring a well tool can include flowing a fluid through an anchor connected to the well tool, thereby outwardly extending a grip member into contact with a well surface, and applying a tensile force to the anchor, thereby increasingly biasing the grip member against the well surface and securing the well tool relative to the well surface. A method of anchoring a tubing cutter in a tubular string can include applying a tensile force from an anchor to the tubular string, and cutting the tubular string while the tensile force is applied from the anchor to the tubular string.

SUBSEA ROTATING CONTROL DEVICE APPARATUS HAVING DEBRIS BARRIER
A riser apparatus includes a riser section and a flow control device. The riser section is disposed on a riser. The flow control device's body installs in the riser section. The assembly may install between uphole and downhole side ports, which may be interconnected by bypass piping and an intermediate device, such as a pump. At least one annular seal rotatably supported by bearings in the body's inner bore can engage a tubular passing therethrough and can seal an annulus therebetween. In one example, pressure uphole of the annular seal may be kept greater than downhole pressure. A debris barrier disposed on the uphole end of the body covers an annular area from an outer perimeter at the exterior of the body toward a central opening at the inner bore. The debris barrier prevents debris, such as drilling cuttings, uphole of the debris barrier from entering into the body's inner bore.
